3 FAQ - Frequently Asked Questions
4 ================================
6 Please have a look at our `Link section
7 <http://www.phpmyadmin.net/home_page/docs.php>`_ on the official
8 phpMyAdmin homepage for in-depth coverage of phpMyAdmin's features and
18 1.1 My server is crashing each time a specific action is required or phpMyAdmin sends a blank page or a page full of cryptic characters to my browser, what can I do?
19 ---------------------------------------------------------------------------------------------------------------------------------------------------------------------
21 Try to set the :config:option:`$cfg['OBGzip']` directive to ``false`` in your
22 :file:`config.inc.php` file and the ``zlib.output_compression`` directive to
23 ``Off`` in your php configuration file.
27 1.2 My Apache server crashes when using phpMyAdmin.
28 ---------------------------------------------------
30 You should first try the latest versions of Apache (and possibly MySQL). If
31 your server keeps crashing, please ask for help in the various Apache support
34 .. seealso:: :ref:`faq1_1`
43 1.4 Using phpMyAdmin on IIS, I'm displayed the error message: "The specified CGI application misbehaved by not returning a complete set of HTTP headers ...".
44 -------------------------------------------------------------------------------------------------------------------------------------------------------------
46 You just forgot to read the *install.txt* file from the PHP
47 distribution. Have a look at the last message in this `PHP bug report #12061
48 <http://bugs.php.net/bug.php?id=12061>`_ from the official PHP bug
53 1.5 Using phpMyAdmin on IIS, I'm facing crashes and/or many error messages with the HTTP.
54 -----------------------------------------------------------------------------------------
56 This is a known problem with the PHP :term:`ISAPI` filter: it's not so stable.
57 Please use instead the cookie authentication mode.
61 1.6 I can't use phpMyAdmin on PWS: nothing is displayed!
62 --------------------------------------------------------
64 This seems to be a PWS bug. Filippo Simoncini found a workaround (at
65 this time there is no better fix): remove or comment the ``DOCTYPE``
66 declarations (2 lines) from the scripts :file:`libraries/Header.class.php`
67 and :file:`index.php`.
71 1.7 How can I GZip a dump or a CSV export? It does not seem to work.
72 --------------------------------------------------------------------
74 This feature is based on the ``gzencode()``
75 PHP function to be more independent of the platform (Unix/Windows,
76 Safe Mode or not, and so on). So, you must have Zlib support
81 1.8 I cannot insert a text file in a table, and I get an error about safe mode being in effect.
82 -----------------------------------------------------------------------------------------------
84 Your uploaded file is saved by PHP in the "upload dir", as defined in
85 :file:`php.ini` by the variable ``upload_tmp_dir`` (usually the system
86 default is */tmp*). We recommend the following setup for Apache
87 servers running in safe mode, to enable uploads of files while being
90 * create a separate directory for uploads: :command:`mkdir /tmp/php`
91 * give ownership to the Apache server's user.group: :command:`chown
92 apache.apache /tmp/php`
93 * give proper permission: :command:`chmod 600 /tmp/php`
94 * put ``upload_tmp_dir = /tmp/php`` in :file:`php.ini`
104 1.10 I'm having troubles when uploading files with phpMyAdmin running on a secure server. My browser is Internet Explorer and I'm using the Apache server.
105 ----------------------------------------------------------------------------------------------------------------------------------------------------------
107 As suggested by "Rob M" in the phpWizard forum, add this line to your
110 .. code-block:: apache
112 SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
114 It seems to clear up many problems between Internet Explorer and SSL.
118 1.11 I get an 'open\_basedir restriction' while uploading a file from the query box.
119 ------------------------------------------------------------------------------------
121 Since version 2.2.4, phpMyAdmin supports servers with open\_basedir
122 restrictions. However you need to create temporary directory and configure it
123 as :config:option:`$cfg['TempDir']`. The uploaded files will be moved there,
124 and after execution of your :term:`SQL` commands, removed.
128 1.12 I have lost my MySQL root password, what can I do?
129 -------------------------------------------------------
131 The MySQL manual explains how to `reset the permissions
132 <http://dev.mysql.com/doc/mysql/en/resetting-permissions.html>`_.
146 1.15 I have problems with *mysql.user* column names.
147 ----------------------------------------------------
149 In previous MySQL versions, the ``User`` and ``Password``columns were
150 named ``user`` and ``password``. Please modify your column names to
151 align with current standards.
155 1.16 I cannot upload big dump files (memory, HTTP or timeout problems).
156 -----------------------------------------------------------------------
158 Starting with version 2.7.0, the import engine has been re–written and
159 these problems should not occur. If possible, upgrade your phpMyAdmin
160 to the latest version to take advantage of the new import features.
162 The first things to check (or ask your host provider to check) are the
163 values of ``upload_max_filesize``, ``memory_limit`` and
164 ``post_max_size`` in the :file:`php.ini` configuration file. All of these
165 three settings limit the maximum size of data that can be submitted
166 and handled by PHP. One user also said that ``post_max_size`` and
167 ``memory_limit`` need to be larger than ``upload_max_filesize``.
168 There exist several workarounds if your upload is too big or your
169 hosting provider is unwilling to change the settings:
171 * Look at the :config:option:`$cfg['UploadDir']` feature. This allows one to upload a file to the server
172 via scp, ftp, or your favorite file transfer method. PhpMyAdmin is
173 then able to import the files from the temporary directory. More
174 information is available in the :ref:`config` of this document.
175 * Using a utility (such as `BigDump
176 <http://www.ozerov.de/bigdump.php>`_) to split the files before
177 uploading. We cannot support this or any third party applications, but
178 are aware of users having success with it.
179 * If you have shell (command line) access, use MySQL to import the files
180 directly. You can do this by issuing the "source" command from within
183 .. code-block:: mysql
189 1.17 Which MySQL versions does phpMyAdmin support?
190 --------------------------------------------------
192 Since phpMyAdmin 3.0.x, only MySQL 5.0.1 and newer are supported. For
193 older MySQL versions, you need to use the latest 2.x branch.
194 phpMyAdmin can connect to your MySQL server using PHP's classic `MySQL
195 extension <http://php.net/mysql>`_ as well as the `improved MySQL
196 extension (MySQLi) <http://php.net/mysqli>`_ that is available in PHP
197 5.0. The latter one should be used unless you have a good reason not
198 to do so. When compiling PHP, we strongly recommend that you manually
199 link the MySQL extension of your choice to a MySQL client library of
200 at least the same minor version since the one that is bundled with
201 some PHP distributions is rather old and might cause problems see
202 :ref:`faq1_17a`. `MariaDB <http://mariadb.org/>`_ is also supported
203 (versions 5.1 and 5.2 were tested).
205 .. versionchanged:: 3.5
206 Since phpMyAdmin 3.5 `Drizzle <http://www.drizzle.org/>`_ is supported.
210 1.17a I cannot connect to the MySQL server. It always returns the error message, "Client does not support authentication protocol requested by server; consider upgrading MySQL client"
211 ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
213 You tried to access MySQL with an old MySQL client library. The
214 version of your MySQL client library can be checked in your phpinfo()
215 output. In general, it should have at least the same minor version as
216 your server - as mentioned in :ref:`faq1_17`. This problem is
217 generally caused by using MySQL version 4.1 or newer. MySQL changed
218 the authentication hash and your PHP is trying to use the old method.
219 The proper solution is to use the `mysqli extension
220 <http://www.php.net/mysqli>`_ with the proper client library to match
221 your MySQL installation. More
222 information (and several workarounds) are located in the `MySQL
223 Documentation <http://dev.mysql.com/doc/mysql/en/old-client.html>`_.
232 1.19 I can't run the "display relations" feature because the script seems not to know the font face I'm using!
233 --------------------------------------------------------------------------------------------------------------
235 The :term:`TCPDF` library we're using for this feature requires some special
236 files to use font faces. Please refers to the `TCPDF manual
237 <http://www.tcpdf.org/>`_ to build these files.
241 1.20 I receive an error about missing mysqli and mysql extensions.
242 ------------------------------------------------------------------
244 To connect to a MySQL server, PHP needs a set of MySQL functions
245 called "MySQL extension". This extension may be part of the PHP
246 distribution (compiled-in), otherwise it needs to be loaded
247 dynamically. Its name is probably *mysqli.so* or *php\_mysqli.dll*.
248 phpMyAdmin tried to load the extension but failed. Usually, the
249 problem is solved by installing a software package called "PHP-MySQL"
250 or something similar.
252 There are currently two interfaces PHP provides as MySQL extensions - ``mysql``
253 and ``mysqli``. The ``mysqli`` is tried first, because it's the best one.
257 1.21 I am running the CGI version of PHP under Unix, and I cannot log in using cookie auth.
258 -------------------------------------------------------------------------------------------
260 In :file:`php.ini`, set ``mysql.max_links`` higher than 1.
264 1.22 I don't see the "Location of text file" field, so I cannot upload.
265 -----------------------------------------------------------------------
267 This is most likely because in :file:`php.ini`, your ``file_uploads``
268 parameter is not set to "on".
272 1.23 I'm running MySQL on a Win32 machine. Each time I create a new table the table and column names are changed to lowercase!
273 ------------------------------------------------------------------------------------------------------------------------------
275 This happens because the MySQL directive ``lower_case_table_names``
276 defaults to 1 (``ON``) in the Win32 version of MySQL. You can change
277 this behavior by simply changing the directive to 0 (``OFF``): Just
278 edit your ``my.ini`` file that should be located in your Windows
279 directory and add the following line to the group [mysqld]:
283 set-variable = lower_case_table_names=0
285 Next, save the file and restart the MySQL service. You can always
286 check the value of this directive using the query
288 .. code-block:: mysql
290 SHOW VARIABLES LIKE 'lower_case_table_names';
299 1.25 I am running Apache with mod\_gzip-1.3.26.1a on Windows XP, and I get problems, such as undefined variables when I run a SQL query.
300 ----------------------------------------------------------------------------------------------------------------------------------------
302 A tip from Jose Fandos: put a comment on the following two lines in
303 httpd.conf, like this:
305 .. code-block:: apache
308 # mod_gzip_item_include file \.php$
309 # mod_gzip_item_include mime "application/x-httpd-php.*"
311 as this version of mod\_gzip on Apache (Windows) has problems handling
312 PHP scripts. Of course you have to restart Apache.
316 1.26 I just installed phpMyAdmin in my document root of IIS but I get the error "No input file specified" when trying to run phpMyAdmin.
317 ----------------------------------------------------------------------------------------------------------------------------------------
319 This is a permission problem. Right-click on the phpmyadmin folder and
320 choose properties. Under the tab Security, click on "Add" and select
321 the user "IUSR\_machine" from the list. Now set his permissions and it
326 1.27 I get empty page when I want to view huge page (eg. db\_structure.php with plenty of tables).
327 --------------------------------------------------------------------------------------------------
329 This was caused by a `PHP bug <http://bugs.php.net/21079>`_ that occur when
330 GZIP output buffering is enabled. If you turn off it (by
331 :config:option:`$cfg['OBGzip']` in :file:`config.inc.php`), it should work.
332 This bug will has been fixed in PHP 5.0.0.
336 1.28 My MySQL server sometimes refuses queries and returns the message 'Errorcode: 13'. What does this mean?
337 ------------------------------------------------------------------------------------------------------------
339 This can happen due to a MySQL bug when having database / table names
340 with upper case characters although ``lower_case_table_names`` is
341 set to 1. To fix this, turn off this directive, convert all database
342 and table names to lower case and turn it on again. Alternatively,
343 there's a bug-fix available starting with MySQLÂ 3.23.56 /
348 1.29 When I create a table or modify a column, I get an error and the columns are duplicated.
349 ---------------------------------------------------------------------------------------------
351 It is possible to configure Apache in such a way that PHP has problems
352 interpreting .php files.
354 The problems occur when two different (and conflicting) set of
357 .. code-block:: apache
365 .. code-block:: apache
367 AddType application/x-httpd-php .php
369 In the case we saw, one set of directives was in
370 ``/etc/httpd/conf/httpd.conf``, while the other set was in
371 ``/etc/httpd/conf/addon-modules/php.conf``. The recommended way is
372 with ``AddType``, so just comment out the first set of lines and
375 .. code-block:: apache
383 1.30 I get the error "navigation.php: Missing hash".
384 ----------------------------------------------------
386 This problem is known to happen when the server is running Turck
387 MMCache but upgrading MMCache to version 2.3.21 solves the problem.
391 1.31 Does phpMyAdmin support PHP 5?
392 -----------------------------------
396 Since release 4.1 phpMyAdmin supports only PHP 5.3 and newer. For PHP 5.2 you
397 can use 4.0.x releases.
401 1.32 Can I use HTTP authentication with IIS?
402 --------------------------------------------
404 Yes. This procedure was tested with phpMyAdmin 2.6.1, PHP 4.3.9 in
405 :term:`ISAPI` mode under :term:`IIS` 5.1.
407 #. In your :file:`php.ini` file, set ``cgi.rfc2616_headers = 0``
408 #. In ``Web Site Properties -> File/Directory Security -> Anonymous
409 Access`` dialog box, check the ``Anonymous access`` checkbox and
410 uncheck any other checkboxes (i.e. uncheck ``Basic authentication``,
411 ``Integrated Windows authentication``, and ``Digest`` if it's
412 enabled.) Click ``OK``.
413 #. In ``Custom Errors``, select the range of ``401;1`` through ``401;5``
414 and click the ``Set to Default`` button.
416 .. seealso:: :rfc:`2616`
425 1.34 Can I access directly to database or table pages?
426 ------------------------------------------------------
428 Yes. Out of the box, you can use :term:`URL` like
429 http://server/phpMyAdmin/index.php?server=X&db=database&table=table&target=script.
430 For ``server`` you use the server number
431 which refers to the order of the server paragraph in
432 :file:`config.inc.php`. Table and script parts are optional. If you want
433 http://server/phpMyAdmin/database[/table][/script] :term:`URL`, you need to do some configuration. Following
434 lines apply only for `Apache <http://httpd.apache.org>`_ web server.
435 First make sure, that you have enabled some features within global
436 configuration. You need ``Options FollowSymLinks`` and ``AllowOverride
437 FileInfo`` enabled for directory where phpMyAdmin is installed and you
438 need mod\_rewrite to be enabled. Then you just need to create
439 following :term:`.htaccess` file in root folder of phpMyAdmin installation (don't
440 forget to change directory name inside of it):
442 .. code-block:: apache
446 RewriteBase /path_to_phpMyAdmin
447 RewriteRule ^([a-zA-Z0-9_]+)/([a-zA-Z0-9_]+)/([a-z_]+\.php)$ index.php?db=$1&table=$2&target=$3 [R]
448 RewriteRule ^([a-zA-Z0-9_]+)/([a-z_]+\.php)$ index.php?db=$1&target=$2 [R]
449 RewriteRule ^([a-zA-Z0-9_]+)/([a-zA-Z0-9_]+)$ index.php?db=$1&table=$2 [R]
450 RewriteRule ^([a-zA-Z0-9_]+)$ index.php?db=$1 [R]
454 1.35 Can I use HTTP authentication with Apache CGI?
455 ---------------------------------------------------
457 Yes. However you need to pass authentication variable to :term:`CGI` using
458 following rewrite rule:
460 .. code-block:: apache
464 RewriteRule .* - [E=REMOTE_USER:%{HTTP:Authorization},L]
468 1.36 I get an error "500 Internal Server Error".
469 ------------------------------------------------
471 There can be many explanations to this and a look at your server's
472 error log file might give a clue.
476 1.37 I run phpMyAdmin on cluster of different machines and password encryption in cookie auth doesn't work.
477 -----------------------------------------------------------------------------------------------------------
479 If your cluster consist of different architectures, PHP code used for
480 encryption/decryption won't work correct. This is caused by use of
481 pack/unpack functions in code. Only solution is to use mcrypt
482 extension which works fine in this case.
486 1.38 Can I use phpMyAdmin on a server on which Suhosin is enabled?
487 ------------------------------------------------------------------
489 Yes but the default configuration values of Suhosin are known to cause
490 problems with some operations, for example editing a table with many
491 columns and no primary key or with textual primary key.
493 Suhosin configuration might lead to malfunction in some cases and it
494 can not be fully avoided as phpMyAdmin is kind of application which
495 needs to transfer big amounts of columns in single HTTP request, what
496 is something what Suhosin tries to prevent. Generally all
497 ``suhosin.request.*``, ``suhosin.post.*`` and ``suhosin.get.*``
498 directives can have negative effect on phpMyAdmin usability. You can
499 always find in your error logs which limit did cause dropping of
500 variable, so you can diagnose the problem and adjust matching
501 configuration variable.
503 The default values for most Suhosin configuration options will work in
504 most scenarios, however you might want to adjust at least following
507 * `suhosin.request.max\_vars <http://www.hardened-
508 php.net/suhosin/configuration.html#suhosin.request.max_vars>`_ should
509 be increased (eg. 2048)
510 * `suhosin.post.max\_vars <http://www.hardened-
511 php.net/suhosin/configuration.html#suhosin.post.max_vars>`_ should be
513 * `suhosin.request.max\_array\_index\_length <http://www.hardened-php.ne
514 t/suhosin/configuration.html#suhosin.request.max_array_index_length>`_
515 should be increased (eg. 256)
516 * `suhosin.post.max\_array\_index\_length <http://www.hardened-php.net/s
517 uhosin/configuration.html#suhosin.post.max_array_index_length>`_
518 should be increased (eg. 256)
519 * `suhosin.request.max\_totalname\_length <http://www.hardened-php.net/s
520 uhosin/configuration.html#suhosin.request.max_totalname_length>`_
521 should be increased (eg. 8192)
522 * `suhosin.post.max\_totalname\_length <http://www.hardened-php.net/suho
523 sin/configuration.html#suhosin.post.max_totalname_length>`_ should be
525 * `suhosin.get.max\_value\_length <http://www.hardened-
526 php.net/suhosin/configuration.html#suhosin.get.max_value_length>`_
527 should be increased (eg. 1024)
528 * `suhosin.sql.bailout\_on\_error <http://www.hardened-
529 php.net/suhosin/configuration.html#suhosin.sql.bailout_on_error>`_
530 needs to be disabled (the default)
531 * `suhosin.log.\* <http://www.hardened-
532 php.net/suhosin/configuration.html#logging_configuration>`_ should not
533 include :term:`SQL`, otherwise you get big
536 You can also disable the warning using the :config:option:`$cfg['SuhosinDisableWarning']`.
540 1.39 When I try to connect via https, I can log in, but then my connection is redirected back to http. What can cause this behavior?
541 ------------------------------------------------------------------------------------------------------------------------------------
543 Be sure that you have enabled ``SSLOptions`` and ``StdEnvVars`` in
544 your Apache configuration.
546 .. seealso:: <http://httpd.apache.org/docs/2.0/mod/mod_ssl.html#ssloptions>
550 1.40 When accessing phpMyAdmin via an Apache reverse proxy, cookie login does not work.
551 ---------------------------------------------------------------------------------------
553 To be able to use cookie auth Apache must know that it has to rewrite
554 the set-cookie headers. Example from the Apache 2.2 documentation:
556 .. code-block:: apache
559 ProxyPass /mirror/foo/ http://backend.example.com/
560 ProxyPassReverse /mirror/foo/ http://backend.example.com/
561 ProxyPassReverseCookieDomain backend.example.com public.example.com
562 ProxyPassReverseCookiePath / /mirror/foo/
564 Note: if the backend url looks like http://host/~user/phpmyadmin, the
565 tilde (~) must be url encoded as %7E in the ProxyPassReverse\* lines.
566 This is not specific to phpmyadmin, it's just the behavior of Apache.
568 .. code-block:: apache
571 ProxyPass /mirror/foo/ http://backend.example.com/~user/phpmyadmin
572 ProxyPassReverse /mirror/foo/ http://backend.example.com/%7Euser/phpmyadmin
573 ProxyPassReverseCookiePath /%7Euser/phpmyadmin /mirror/foo
575 .. seealso:: <http://httpd.apache.org/docs/2.2/mod/mod_proxy.html>
579 1.41 When I view a database and ask to see its privileges, I get an error about an unknown column.
580 --------------------------------------------------------------------------------------------------
582 The MySQL server's privilege tables are not up to date, you need to
583 run the :command:`mysql_upgrade` command on the server.
587 1.42 How can I prevent robots from accessing phpMyAdmin?
588 --------------------------------------------------------
590 You can add various rules to :term:`.htaccess` to filter access based on user agent
591 field. This is quite easy to circumvent, but could prevent at least
592 some robots accessing your installation.
594 .. code-block:: apache
599 # Allow only GET and POST verbs
600 RewriteCond %{REQUEST_METHOD} !^(GET|POST)$ [NC,OR]
602 # Ban Typical Vulnerability Scanners and others
603 # Kick out Script Kiddies
604 RewriteCond %{HTTP_USER_AGENT} ^(java|curl|wget).* [NC,OR]
605 RewriteCond %{HTTP_USER_AGENT} ^.*(libwww-perl|curl|wget|python|nikto|wkito|pikto|scan|acunetix).* [NC,OR]
606 RewriteCond %{HTTP_USER_AGENT} ^.*(winhttp|HTTrack|clshttp|archiver|loader|email|harvest|extract|grab|miner).* [NC,OR]
608 # Ban Search Engines, Crawlers to your administrative panel

618 1.43 Why can't I display the structure of my table containing hundreds of columns?
619 ----------------------------------------------------------------------------------
621 Because your PHP's ``memory_limit`` is too low; adjust it in :file:`php.ini`.
630 2.1 The error message "Warning: Cannot add header information - headers already sent by ..." is displayed, what's the problem?
631 ------------------------------------------------------------------------------------------------------------------------------
633 Edit your :file:`config.inc.php` file and ensure there is nothing (I.E. no
634 blank lines, no spaces, no characters...) neither before the ``<?php`` tag at
635 the beginning, neither after the ``?>`` tag at the end. We also got a report
636 from a user under :term:`IIS`, that used a zipped distribution kit: the file
637 :file:`libraries/Config.class.php` contained an end-of-line character (hex 0A)
638 at the end; removing this character cleared his errors.
642 2.2 phpMyAdmin can't connect to MySQL. What's wrong?
643 ----------------------------------------------------
645 Either there is an error with your PHP setup or your username/password
646 is wrong. Try to make a small script which uses mysql\_connect and see
647 if it works. If it doesn't, it may be you haven't even compiled MySQL
652 2.3 The error message "Warning: MySQL Connection Failed: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (111) ..." is displayed. What can I do?
653 ---------------------------------------------------------------------------------------------------------------------------------------------------------------------
655 For RedHat users, Harald Legner suggests this on the mailing list:
657 On my RedHat-Box the socket of MySQL is */var/lib/mysql/mysql.sock*.
658 In your :file:`php.ini` you will find a line
662 mysql.default_socket = /tmp/mysql.sock
668 mysql.default_socket = /var/lib/mysql/mysql.sock
670 Then restart apache and it will work.
672 Here is a fix suggested by Brad Ummer:
674 * First, you need to determine what socket is being used by MySQL. To do
675 this, telnet to your server and go to the MySQL bin directory. In this
676 directory there should be a file named *mysqladmin*. Type
677 ``./mysqladmin variables``, and this should give you a bunch of info
678 about your MySQL server, including the socket (*/tmp/mysql.sock*, for
680 * Then, you need to tell PHP to use this socket. To do this in
681 phpMyAdmin, you need to complete the socket information in the
682 :file:`config.inc.php`. For example:
683 :config:option:`$cfg['Servers'][$i]['socket']` Please also make sure that
684 the permissions of this file allow to be readable by your webserver (i.e.
687 Have also a look at the `corresponding section of the MySQL
688 documentation <http://dev.mysql.com/doc/en/can-not-connect-to-
693 2.4 Nothing is displayed by my browser when I try to run phpMyAdmin, what can I do?
694 -----------------------------------------------------------------------------------
696 Try to set the :config:option:`$cfg['OBGzip']` directive to ``false`` in the phpMyAdmin configuration
697 file. It helps sometime. Also have a look at your PHP version number:
698 if it contains "b" or "alpha" it means you're running a testing
699 version of PHP. That's not a so good idea, please upgrade to a plain
704 2.5 Each time I want to insert or change a row or drop a database or a table, an error 404 (page not found) is displayed or, with HTTP or cookie authentication, I'm asked to log in again. What's wrong?
705 ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
707 Check the value you set for the :config:option:`$cfg['PmaAbsoluteUri']` directive in the phpMyAdmin
712 2.6 I get an "Access denied for user: 'root@localhost' (Using password: YES)"-error when trying to access a MySQL-Server on a host which is port-forwarded for my localhost.
713 ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
715 When you are using a port on your localhost, which you redirect via
716 port-forwarding to another host, MySQL is not resolving the localhost
717 as expected. Erik Wasser explains: The solution is: if your host is
718 "localhost" MySQL (the command line tool :command:`mysql` as well) always
719 tries to use the socket connection for speeding up things. And that
720 doesn't work in this configuration with port forwarding. If you enter
721 "127.0.0.1" as hostname, everything is right and MySQL uses the
722 :term:`TCP` connection.
726 2.7 Using and creating themes
727 -----------------------------
729 Themes are configured with :config:option:`$cfg['ThemePath']`,
730 :config:option:`$cfg['ThemeManager']` and :config:option:`$cfg['ThemeDefault']`.
731 Under :config:option:`$cfg['ThemePath']`, you should not delete the
732 directory ``pmahomme`` or its underlying structure, because this is the
733 system theme used by phpMyAdmin. ``pmahomme`` contains all images and
734 styles, for backwards compatibility and for all themes that would not
735 include images or css-files. If :config:option:`$cfg['ThemeManager']`
736 is enabled, you can select your favorite theme on the main page. Your selected
737 theme will be stored in a cookie.
741 * make a new subdirectory (for example "your\_theme\_name") under :config:option:`$cfg['ThemePath']` (by
743 * copy the files and directories from ``pmahomme`` to "your\_theme\_name"
744 * edit the css-files in "your\_theme\_name/css"
745 * put your new images in "your\_theme\_name/img"
746 * edit :file:`layout.inc.php` in "your\_theme\_name"
747 * edit :file:`info.inc.php` in "your\_theme\_name" to contain your chosen
748 theme name, that will be visible in user interface
749 * make a new screenshot of your theme and save it under
750 "your\_theme\_name/screen.png"
752 In theme directory there is file :file:`info.inc.php` which contains theme
753 verbose name, theme generation and theme version. These versions and
754 generations are enumerated from 1 and do not have any direct
755 dependence on phpMyAdmin version. Themes within same generation should
756 be backwards compatible - theme with version 2 should work in
757 phpMyAdmin requiring version 1. Themes with different generation are
760 If you do not want to use your own symbols and buttons, remove the
761 directory "img" in "your\_theme\_name". phpMyAdmin will use the
762 default icons and buttons (from the system-theme ``pmahomme``).
764 .. _faqmissingparameters:
766 2.8 I get "Missing parameters" errors, what can I do?
767 -----------------------------------------------------
769 Here are a few points to check:
771 * In :file:`config.inc.php`, try to leave the :config:option:`$cfg['PmaAbsoluteUri']` directive empty. See also
773 * Maybe you have a broken PHP installation or you need to upgrade your
774 Zend Optimizer. See <http://bugs.php.net/bug.php?id=31134>.
775 * If you are using Hardened PHP with the ini directive
776 ``varfilter.max_request_variables`` set to the default (200) or
777 another low value, you could get this error if your table has a high
778 number of columns. Adjust this setting accordingly. (Thanks to Klaus
779 Dorninger for the hint).
780 * In the :file:`php.ini` directive ``arg_separator.input``, a value of ";"
781 will cause this error. Replace it with "&;".
782 * If you are using `Hardened-PHP <http://www.hardened-php.net/>`_, you
783 might want to increase `request limits <http://www.hardened-
784 php.net/hphp/troubleshooting.html>`_.
785 * The directory specified in the :file:`php.ini` directive
786 ``session.save_path`` does not exist or is read-only.
790 2.9 Seeing an upload progress bar
791 ---------------------------------
793 To be able to see a progress bar during your uploads, your server must
794 have the `APC <http://pecl.php.net/package/APC>`_ extension, the
795 `uploadprogress <http://pecl.php.net/package/uploadprogress>`_ one, or
796 you must be running PHP 5.4.0 or higher. Moreover, the JSON extension
797 has to be enabled in your PHP.
799 If using APC, you must set ``apc.rfc1867`` to ``on`` in your :file:`php.ini`.
801 If using PHP 5.4.0 or higher, you must set
802 ``session.upload_progress.enabled`` to ``1`` in your :file:`php.ini`. However,
803 starting from phpMyAdmin version 4.0.4, session-based upload progress has
804 been temporarily deactivated due to its problematic behavior.
806 .. seealso:: :rfc:`1867`
815 3.1 When using HTTP authentication, a user who logged out can not log in again in with the same nick.
816 -----------------------------------------------------------------------------------------------------
818 This is related to the authentication mechanism (protocol) used by
819 phpMyAdmin. To bypass this problem: just close all the opened browser
820 windows and then go back to phpMyAdmin. You should be able to log in
825 3.2 When dumping a large table in compressed mode, I get a memory limit error or a time limit error.
826 ----------------------------------------------------------------------------------------------------
828 Compressed dumps are built in memory and because of this are limited
829 to php's memory limit. For GZip/BZip2 exports this can be overcome
830 since 2.5.4 using :config:option:`$cfg['CompressOnFly']` (enabled by default).
831 Zip exports can not be handled this way, so if you need Zip files for larger
832 dump, you have to use another way.
836 3.3 With InnoDB tables, I lose foreign key relationships when I rename a table or a column.
837 -------------------------------------------------------------------------------------------
839 This is an InnoDB bug, see <http://bugs.mysql.com/bug.php?id=21704>.
843 3.4 I am unable to import dumps I created with the mysqldump tool bundled with the MySQL server distribution.
844 -------------------------------------------------------------------------------------------------------------
846 The problem is that older versions of ``mysqldump`` created invalid
849 .. code-block:: mysql
854 -- Host: localhost Database: database
855 ---------------------------------------------------------
856 -- Server version 3.23.54
858 The invalid part of the code is the horizontal line made of dashes
859 that appears once in every dump created with mysqldump. If you want to
860 run your dump you have to turn it into valid MySQL. This means, you
861 have to add a whitespace after the first two dashes of the line or add
862 a # before it: ``-- -------------------------------------------------------`` or
863 ``#---------------------------------------------------------``
867 3.5 When using nested folders, multiple hierarchies are displayed in a wrong manner.
868 ------------------------------------------------------------------------------------
870 Please note that you should not use the separating string multiple
871 times without any characters between them, or at the beginning/end of
872 your table name. If you have to, think about using another
873 TableSeparator or disabling that feature.
875 .. seealso:: :config:option:`$cfg['NavigationTreeTableSeparator']`
884 3.7 I have table with many (100+) columns and when I try to browse table I get series of errors like "Warning: unable to parse url". How can this be fixed?
885 -----------------------------------------------------------------------------------------------------------------------------------------------------------
887 Your table neither have a primary key nor an unique one, so we must
888 use a long expression to identify this row. This causes problems to
889 parse\_url function. The workaround is to create a primary or unique
894 3.8 I cannot use (clickable) HTML-forms in columns where I put a MIME-Transformation onto!
895 ------------------------------------------------------------------------------------------
897 Due to a surrounding form-container (for multi-row delete checkboxes),
898 no nested forms can be put inside the table where phpMyAdmin displays
899 the results. You can, however, use any form inside of a table if keep
900 the parent form-container with the target to tbl\_row\_delete.php and
901 just put your own input-elements inside. If you use a custom submit
902 input field, the form will submit itself to the displaying page again,
903 where you can validate the $HTTP\_POST\_VARS in a transformation. For
904 a tutorial on how to effectively use transformations, see our `Link
905 section <http://www.phpmyadmin.net/home_page/docs.php>`_ on the
906 official phpMyAdmin-homepage.
910 3.9 I get error messages when using "--sql\_mode=ANSI" for the MySQL server.
911 ----------------------------------------------------------------------------
913 When MySQL is running in ANSI-compatibility mode, there are some major
914 differences in how :term:`SQL` is structured (see
915 <http://dev.mysql.com/doc/mysql/en/ansi-mode.html>). Most important of all, the
916 quote-character (") is interpreted as an identifier quote character and not as
917 a string quote character, which makes many internal phpMyAdmin operations into
918 invalid :term:`SQL` statements. There is no
919 workaround to this behaviour. News to this item will be posted in `Bug report
920 #1013 <https://sourceforge.net/p/phpmyadmin/bugs/1013/>`_.
924 3.10 Homonyms and no primary key: When the results of a SELECT display more that one column with the same value (for example ``SELECT lastname from employees where firstname like 'A%'`` and two "Smith" values are displayed), if I click Edit I cannot be sure that I am editing the intended row.
925 -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
927 Please make sure that your table has a primary key, so that phpMyAdmin
928 can use it for the Edit and Delete links.
932 3.11 The number of rows for InnoDB tables is not correct.
933 ---------------------------------------------------------
935 phpMyAdmin uses a quick method to get the row count, and this method only
936 returns an approximate count in the case of InnoDB tables. See
937 :config:option:`$cfg['MaxExactCount']` for a way to modify those results, but
938 this could have a serious impact on performance.
939 However, one can easily replace the approximate row count with exact count by
940 simply clicking on the approximate count. This can also be done for all tables
941 at once by clicking on the rows sum displayed at the bottom.
950 3.13 I get an error when entering ``USE`` followed by a db name containing an hyphen.
951 -------------------------------------------------------------------------------------
953 The tests I have made with MySQL 5.1.49 shows that the API does not
954 accept this syntax for the USE command.
958 3.14 I am not able to browse a table when I don't have the right to SELECT one of the columns.
959 ----------------------------------------------------------------------------------------------
961 This has been a known limitation of phpMyAdmin since the beginning and
962 it's not likely to be solved in the future.
981 3.18 When I import a CSV file that contains multiple tables, they are lumped together into a single table.
982 ----------------------------------------------------------------------------------------------------------
984 There is no reliable way to differentiate tables in :term:`CSV` format. For the
985 time being, you will have to break apart :term:`CSV` files containing multiple
990 3.19 When I import a file and have phpMyAdmin determine the appropriate data structure it only uses int, decimal, and varchar types.
991 ------------------------------------------------------------------------------------------------------------------------------------
993 Currently, the import type-detection system can only assign these
994 MySQL types to columns. In future, more will likely be added but for
995 the time being you will have to edit the structure to your liking
996 post-import. Also, you should note the fact that phpMyAdmin will use
997 the size of the largest item in any given column as the column size
998 for the appropriate type. If you know you will be adding larger items
999 to that column then you should manually adjust the column sizes
1000 accordingly. This is done for the sake of efficiency.
1004 3.20 After upgrading, some bookmarks are gone or their content cannot be shown.
1005 -------------------------------------------------------------------------------
1007 At some point, the character set used to store bookmark content has changed.
1008 It's better to recreate your bookmark from the newer phpMyAdmin version.
1012 ISPs, multi-user installations
1013 ++++++++++++++++++++++++++++++
1017 4.1 I'm an ISP. Can I setup one central copy of phpMyAdmin or do I need to install it for each customer?
1018 --------------------------------------------------------------------------------------------------------
1020 Since version 2.0.3, you can setup a central copy of phpMyAdmin for all your
1021 users. The development of this feature was kindly sponsored by NetCologne GmbH.
1022 This requires a properly setup MySQL user management and phpMyAdmin
1023 :term:`HTTP` or cookie authentication.
1025 .. seealso:: :ref:`authentication_modes`
1029 4.2 What's the preferred way of making phpMyAdmin secure against evil access?
1030 -----------------------------------------------------------------------------
1032 This depends on your system. If you're running a server which cannot be
1033 accessed by other people, it's sufficient to use the directory protection
1034 bundled with your webserver (with Apache you can use :term:`.htaccess` files,
1035 for example). If other people have telnet access to your server, you should use
1036 phpMyAdmin's :term:`HTTP` or cookie authentication features.
1040 * Your :file:`config.inc.php` file should be ``chmod 660``.
1041 * All your phpMyAdmin files should be chown -R phpmy.apache, where phpmy
1042 is a user whose password is only known to you, and apache is the group
1043 under which Apache runs.
1044 * Follow security recommendations for PHP and your webserver.
1048 4.3 I get errors about not being able to include a file in */lang* or in */libraries*.
1049 --------------------------------------------------------------------------------------
1051 Check :file:`php.ini`, or ask your sysadmin to check it. The
1052 ``include_path`` must contain "." somewhere in it, and
1053 ``open_basedir``, if used, must contain "." and "./lang" to allow
1054 normal operation of phpMyAdmin.
1058 4.4 phpMyAdmin always gives "Access denied" when using HTTP authentication.
1059 ---------------------------------------------------------------------------
1061 This could happen for several reasons:
1063 * :config:option:`$cfg['Servers'][$i]['controluser']` and/or :config:option:`$cfg['Servers'][$i]['controlpass']` are wrong.
1064 * The username/password you specify in the login dialog are invalid.
1065 * You have already setup a security mechanism for the phpMyAdmin-
1066 directory, eg. a :term:`.htaccess` file. This would interfere with phpMyAdmin's
1067 authentication, so remove it.
1071 4.5 Is it possible to let users create their own databases?
1072 -----------------------------------------------------------
1074 Starting with 2.2.5, in the user management page, you can enter a
1075 wildcard database name for a user (for example "joe%"), and put the
1076 privileges you want. For example, adding ``SELECT, INSERT, UPDATE,
1077 DELETE, CREATE, DROP, INDEX, ALTER`` would let a user create/manage
1078 his/her database(s).
1082 4.6 How can I use the Host-based authentication additions?
1083 ----------------------------------------------------------
1085 If you have existing rules from an old :term:`.htaccess` file, you can take them and
1086 add a username between the ``'deny'``/``'allow'`` and ``'from'``
1087 strings. Using the username wildcard of ``'%'`` would be a major
1088 benefit here if your installation is suited to using it. Then you can
1089 just add those updated lines into the
1090 :config:option:`$cfg['Servers'][$i]['AllowDeny']['rules']` array.
1092 If you want a pre-made sample, you can try this fragment. It stops the
1093 'root' user from logging in from any networks other than the private
1094 network :term:`IP` blocks.
1099 //block root from logging in except from the private networks
1100 $cfg['Servers'][$i]['AllowDeny']['order'] = 'deny,allow';
1101 $cfg['Servers'][$i]['AllowDeny']['rules'] = array(
1102 'deny root from all',
1103 'allow root from localhost',
1104 'allow root from 10.0.0.0/8',
1105 'allow root from 192.168.0.0/16',
1106 'allow root from 172.16.0.0/12',
1111 4.7 Authentication window is displayed more than once, why?
1112 -----------------------------------------------------------
1114 This happens if you are using a :term:`URL` to start phpMyAdmin which is
1115 different than the one set in your :config:option:`$cfg['PmaAbsoluteUri']`. For
1116 example, a missing "www", or entering with an :term:`IP` address while a domain
1117 name is defined in the config file.
1121 4.8 Which parameters can I use in the URL that starts phpMyAdmin?
1122 -----------------------------------------------------------------
1124 When starting phpMyAdmin, you can use the ``db``, ``pma_username``,
1125 ``pma_password`` and ``server`` parameters. This last one can contain
1126 either the numeric host index (from ``$i`` of the configuration file)
1127 or one of the host names present in the configuration file. Using
1128 ``pma_username`` and ``pma_password`` has been tested along with the
1129 usage of 'cookie' ``auth_type``.
1133 Browsers or client OS
1134 +++++++++++++++++++++
1138 5.1 I get an out of memory error, and my controls are non-functional, when trying to create a table with more than 14 columns.
1139 ------------------------------------------------------------------------------------------------------------------------------
1141 We could reproduce this problem only under Win98/98SE. Testing under
1142 WinNT4 or Win2K, we could easily create more than 60 columns. A
1143 workaround is to create a smaller number of columns, then come back to
1144 your table properties and add the other columns.
1148 5.2 With Xitami 2.5b4, phpMyAdmin won't process form fields.
1149 ------------------------------------------------------------
1151 This is not a phpMyAdmin problem but a Xitami known bug: you'll face
1152 it with each script/website that use forms. Upgrade or downgrade your
1157 5.3 I have problems dumping tables with Konqueror (phpMyAdmin 2.2.2).
1158 ---------------------------------------------------------------------
1160 With Konqueror 2.1.1: plain dumps, zip and GZip dumps work ok, except
1161 that the proposed file name for the dump is always 'tbl\_dump.php'.
1162 Bzip2 dumps don't seem to work. With Konqueror 2.2.1: plain dumps
1163 work; zip dumps are placed into the user's temporary directory, so
1164 they must be moved before closing Konqueror, or else they disappear.
1165 GZip dumps give an error message. Testing needs to be done for
1170 5.4 I can't use the cookie authentication mode because Internet Explorer never stores the cookies.
1171 --------------------------------------------------------------------------------------------------
1173 MS Internet Explorer seems to be really buggy about cookies, at least
1178 5.5 In Internet Explorer 5.0, I get JavaScript errors when browsing my rows.
1179 ----------------------------------------------------------------------------
1181 Upgrade to at least Internet Explorer 5.5 SP2.
1185 5.6 In Internet Explorer 5.0, 5.5 or 6.0, I get an error (like "Page not found") when trying to modify a row in a table with many columns, or with a text column.
1186 -----------------------------------------------------------------------------------------------------------------------------------------------------------------
1188 Your table neither have a primary key nor an unique one, so we must use a long
1189 :term:`URL` to identify this row. There is a limit on the length of the
1190 :term:`URL` in those browsers, and this not happen in Netscape, for example.
1191 The workaround is to create a primary or unique key, or use another browser.
1195 5.7 I refresh (reload) my browser, and come back to the welcome page.
1196 ---------------------------------------------------------------------
1198 Some browsers support right-clicking into the frame you want to
1199 refresh, just do this in the right frame.
1203 5.8 With Mozilla 0.9.7 I have problems sending a query modified in the query box.

1214 This is a Mozilla bug (see bug #26882 at `BugZilla
1215 <http://bugzilla.mozilla.org/>`_).
1219 5.10 With Netscape 4.75 I get empty rows between each row of data in a CSV exported file.
1220 -----------------------------------------------------------------------------------------
1222 This is a known Netscape 4.75 bug: it adds some line feeds when
1223 exporting data in octet-stream mode. Since we can't detect the
1224 specific Netscape version, we cannot workaround this bug.
1228 5.11 Extended-ASCII characters like German umlauts are displayed wrong.
1229 -----------------------------------------------------------------------
1231 Please ensure that you have set your browser's character set to the
1232 one of the language file you have selected on phpMyAdmin's start page.
1233 Alternatively, you can try the auto detection mode that is supported
1234 by the recent versions of the most browsers.

1249 This is a bug in Internet Explorer, other browsers do not behave this
1254 5.14 Using Opera6, I can manage to get to the authentication, but nothing happens after that, only a blank screen.
1255 ------------------------------------------------------------------------------------------------------------------
1257 Please upgrade to Opera7 at least.
1261 5.15 I have display problems with Safari.
1262 -----------------------------------------
1264 Please upgrade to at least version 1.2.3.
1268 5.16 With Internet Explorer, I get "Access is denied" Javascript errors. Or I cannot make phpMyAdmin work under Windows.
1269 ------------------------------------------------------------------------------------------------------------------------
1271 Please check the following points:
1273 * Maybe you have defined your :config:option:`$cfg['PmaAbsoluteUri']` setting in
1274 :file:`config.inc.php` to an :term:`IP` address and you are starting phpMyAdmin
1275 with a :term:`URL` containing a domain name, or the reverse situation.
1276 * Security settings in IE and/or Microsoft Security Center are too high,
1277 thus blocking scripts execution.
1278 * The Windows Firewall is blocking Apache and MySQL. You must allow
1279 :term:`HTTP` ports (80 or 443) and MySQL
1280 port (usually 3306) in the "in" and "out" directions.
1284 5.17 With Firefox, I cannot delete rows of data or drop a database.
1285 -------------------------------------------------------------------
1287 Many users have confirmed that the Tabbrowser Extensions plugin they
1288 installed in their Firefox is causing the problem.
1292 5.18 With Konqueror 4.2.x an invalid ``LIMIT`` clause is generated when I browse a table.
1293 -----------------------------------------------------------------------------------------
1295 This happens only when both of these conditions are met: using the
1296 ``http`` authentication mode and ``register_globals`` being set to
1297 ``On`` on the server. It seems to be a browser-specific problem;
1298 meanwhile use the ``cookie`` authentication mode.
1302 5.19 I get JavaScript errors in my browser.
1303 -------------------------------------------
1305 Issues have been reported with some combinations of browser
1306 extensions. To troubleshoot, disable all extensions then clear your
1307 browser cache to see if the problem goes away.
1316 6.1 I can't insert new rows into a table / I can't create a table - MySQL brings up a SQL error.
1317 ------------------------------------------------------------------------------------------------
1319 Examine the :term:`SQL` error with care.
1320 Often the problem is caused by specifying a wrong column-type. Common
1323 * Using ``VARCHAR`` without a size argument
1324 * Using ``TEXT`` or ``BLOB`` with a size argument
1326 Also, look at the syntax chapter in the MySQL manual to confirm that
1327 your syntax is correct.
1331 6.2 When I create a table, I set an index for two columns and phpMyAdmin generates only one index with those two columns.
1332 -------------------------------------------------------------------------------------------------------------------------
1334 This is the way to create a multi-columns index. If you want two
1335 indexes, create the first one when creating the table, save, then
1336 display the table properties and click the Index link to create the
1341 6.3 How can I insert a null value into my table?
1342 ------------------------------------------------
1344 Since version 2.2.3, you have a checkbox for each column that can be
1345 null. Before 2.2.3, you had to enter "null", without the quotes, as
1346 the column's value. Since version 2.5.5, you have to use the checkbox
1347 to get a real NULL value, so if you enter "NULL" this means you want a
1348 literal NULL in the column, and not a NULL value (this works in PHP4).
1352 6.4 How can I backup my database or table?
1353 ------------------------------------------
1355 Click on a database or table name in the navigation panel, the properties will
1356 be displayed. Then on the menu, click "Export", you can dump the structure, the
1357 data, or both. This will generate standard :term:`SQL` statements that can be
1358 used to recreate your database/table. You will need to choose "Save as file",
1359 so that phpMyAdmin can transmit the resulting dump to your station. Depending
1360 on your PHP configuration, you will see options to compress the dump. See also
1361 the :config:option:`$cfg['ExecTimeLimit']` configuration variable. For
1362 additional help on this subject, look for the word "dump" in this document.
1366 6.5 How can I restore (upload) my database or table using a dump? How can I run a ".sql" file?
1367 ----------------------------------------------------------------------------------------------
1369 Click on a database name in the navigation panel, the properties will
1370 be displayed. Select "Import" from the list of tabs in the right–hand
1371 frame (or ":term:`SQL`" if your phpMyAdmin
1372 version is previous to 2.7.0). In the "Location of the text file"
1373 section, type in the path to your dump filename, or use the Browse
1374 button. Then click Go. With version 2.7.0, the import engine has been
1375 re–written, if possible it is suggested that you upgrade to take
1376 advantage of the new features. For additional help on this subject,
1377 look for the word "upload" in this document.
1381 6.6 How can I use the relation table in Query-by-example?
1382 ---------------------------------------------------------
1384 Here is an example with the tables persons, towns and countries, all
1385 located in the database "mydb". If you don't have a ``pma__relation``
1386 table, create it as explained in the configuration section. Then
1387 create the example tables:
1389 .. code-block:: mysql
1392 CREATE TABLE REL_countries (
1393 country_code char(1) NOT NULL default '',
1394 description varchar(10) NOT NULL default '',
1395 PRIMARY KEY (country_code)
1398 INSERT INTO REL_countries VALUES ('C', 'Canada');
1400 CREATE TABLE REL_persons (
1401 id tinyint(4) NOT NULL auto_increment,
1402 person_name varchar(32) NOT NULL default '',
1403 town_code varchar(5) default '0',
1404 country_code char(1) NOT NULL default '',
1408 INSERT INTO REL_persons VALUES (11, 'Marc', 'S', '');
1409 INSERT INTO REL_persons VALUES (15, 'Paul', 'S', 'C');
1411 CREATE TABLE REL_towns (
1412 town_code varchar(5) NOT NULL default '0',
1413 description varchar(30) NOT NULL default '',
1414 PRIMARY KEY (town_code)
1417 INSERT INTO REL_towns VALUES ('S', 'Sherbrooke');
1418 INSERT INTO REL_towns VALUES ('M', 'Montréal');
1420 To setup appropriate links and display information:
1422 * on table "REL\_persons" click Structure, then Relation view
1423 * for "town\_code", choose from dropdowns, "mydb", "REL\_towns", "code"
1424 for foreign database, table and column respectively
1425 * for "country\_code", choose from dropdowns, "mydb", "REL\_countries",
1426 "country\_code" for foreign database, table and column respectively
1427 * on table "REL\_towns" click Structure, then Relation view
1428 * in "Choose column to display", choose "description"
1429 * repeat the two previous steps for table "REL\_countries"
1431 Then test like this:
1433 * Click on your db name in the navigation panel
1435 * Use tables: persons, towns, countries
1436 * Click "Update query"
1437 * In the columns row, choose persons.person\_name and click the "Show"
1439 * Do the same for towns.description and countries.descriptions in the
1441 * Click "Update query" and you will see in the query box that the
1442 correct joins have been generated
1443 * Click "Submit query"
1447 6.7 How can I use the "display column" feature?
1448 -----------------------------------------------
1450 Starting from the previous example, create the ``pma__table_info`` as
1451 explained in the configuration section, then browse your persons
1452 table, and move the mouse over a town code or country code. See also
1453 :ref:`faq6_21` for an additional feature that "display column"
1454 enables: drop-down list of possible values.
1458 6.8 How can I produce a PDF schema of my database?
1459 --------------------------------------------------
1461 First the configuration variables "relation", "table\_coords" and
1462 "pdf\_pages" have to be filled in. Then you need to think about your
1463 schema layout. Which tables will go on which pages?
1465 * Select your database in the navigation panel.
1466 * Choose "Operations" in the navigation bar at the top.
1467 * Choose "Edit :term:`PDF` Pages" near the
1469 * Enter a name for the first :term:`PDF` page
1470 and click Go. If you like, you can use the "automatic layout," which
1471 will put all your linked tables onto the new page.
1472 * Select the name of the new page (making sure the Edit radio button is
1473 selected) and click Go.
1474 * Select a table from the list, enter its coordinates and click Save.
1475 Coordinates are relative; your diagram will be automatically scaled to
1476 fit the page. When initially placing tables on the page, just pick any
1477 coordinates -- say, 50x50. After clicking Save, you can then use the
1478 :ref:`wysiwyg` to position the element correctly.
1479 * When you'd like to look at your :term:`PDF`, first be sure to click the Save
1480 button beneath the list of tables and coordinates, to save any changes you
1481 made there. Then scroll all the way down, select the :term:`PDF` options you
1483 * Internet Explorer for Windows may suggest an incorrect filename when
1484 you try to save a generated :term:`PDF`.
1485 When saving a generated :term:`PDF`, be
1486 sure that the filename ends in ".pdf", for example "schema.pdf".
1487 Browsers on other operating systems, and other browsers on Windows, do
1488 not have this problem.
1492 6.9 phpMyAdmin is changing the type of one of my columns!
1493 ---------------------------------------------------------
1495 No, it's MySQL that is doing `silent column type changing
1496 <http://dev.mysql.com/doc/en/silent-column-changes.html>`_.
1500 6.10 When creating a privilege, what happens with underscores in the database name?
1501 -----------------------------------------------------------------------------------
1503 If you do not put a backslash before the underscore, this is a
1504 wildcard grant, and the underscore means "any character". So, if the
1505 database name is "john\_db", the user would get rights to john1db,
1506 john2db ... If you put a backslash before the underscore, it means
1507 that the database name will have a real underscore.
1511 6.11 What is the curious symbol ø in the statistics pages?
1512 ----------------------------------------------------------
1518 6.12 I want to understand some Export options.
1519 ----------------------------------------------
1523 * "Add DROP TABLE" will add a line telling MySQL to `drop the table
1524 <http://dev.mysql.com/doc/mysql/en/drop-table.html>`_, if it already
1525 exists during the import. It does NOT drop the table after your
1526 export, it only affects the import file.
1527 * "If Not Exists" will only create the table if it doesn't exist.
1528 Otherwise, you may get an error if the table name exists but has a
1529 different structure.
1530 * "Add AUTO\_INCREMENT value" ensures that AUTO\_INCREMENT value (if
1531 any) will be included in backup.
1532 * "Enclose table and column names with backquotes" ensures that column
1533 and table names formed with special characters are protected.
1534 * "Add into comments" includes column comments, relations, and MIME
1535 types set in the pmadb in the dump as :term:`SQL` comments
1540 * "Complete inserts" adds the column names on every INSERT command, for
1541 better documentation (but resulting file is bigger).
1542 * "Extended inserts" provides a shorter dump file by using only once the
1543 INSERT verb and the table name.
1544 * "Delayed inserts" are best explained in the `MySQL manual - INSERT DELAYED Syntax
1545 <http://dev.mysql.com/doc/mysql/en/insert-delayed.html>`_.
1546 * "Ignore inserts" treats errors as a warning instead. Again, more info
1547 is provided in the `MySQL manual - INSERT Syntax
1548 <http://dev.mysql.com/doc/mysql/en/insert.html>`_, but basically with
1549 this selected, invalid values are adjusted and inserted rather than
1550 causing the entire statement to fail.
1554 6.13 I would like to create a database with a dot in its name.
1555 --------------------------------------------------------------
1557 This is a bad idea, because in MySQL the syntax "database.table" is
1558 the normal way to reference a database and table name. Worse, MySQL
1559 will usually let you create a database with a dot, but then you cannot
1560 work with it, nor delete it.
1562 .. _faqsqlvalidator:
1569 6.15 I want to add a BLOB column and put an index on it, but MySQL says "BLOB column '...' used in key specification without a key length".
1570 -------------------------------------------------------------------------------------------------------------------------------------------
1572 The right way to do this, is to create the column without any indexes,
1573 then display the table structure and use the "Create an index" dialog.
1574 On this page, you will be able to choose your BLOB column, and set a
1575 size to the index, which is the condition to create an index on a BLOB
1580 6.16 How can I simply move in page with plenty editing fields?
1581 --------------------------------------------------------------
1583 You can use :kbd:`Ctrl+arrows` (:kbd:`Option+Arrows` in Safari) for moving on
1584 most pages with many editing fields (table structure changes, row editing,
1589 6.17 Transformations: I can't enter my own mimetype! WTF is this feature then useful for?
1590 -----------------------------------------------------------------------------------------
1592 Slow down :). Defining mimetypes is of no use, if you can't put
1593 transformations on them. Otherwise you could just put a comment on the
1594 column. Because entering your own mimetype will cause serious syntax
1595 checking issues and validation, this introduces a high-risk false-
1596 user-input situation. Instead you have to initialize mimetypes using
1597 functions or empty mimetype definitions.
1599 Plus, you have a whole overview of available mimetypes. Who knows all those
1600 mimetypes by heart so he/she can enter it at will?
1604 6.18 Bookmarks: Where can I store bookmarks? Why can't I see any bookmarks below the query box? What are these variables for?
1605 -----------------------------------------------------------------------------------------------------------------------------
1607 Any query you have executed can be stored as a bookmark on the page
1608 where the results are displayed. You will find a button labeled
1609 'Bookmark this query' just at the end of the page. As soon as you have
1610 stored a bookmark, it is related to the database you run the query on.
1611 You can now access a bookmark dropdown on each page, the query box
1612 appears on for that database.
1614 You can also have, inside the query, placeholders for variables.
1615 This is done by inserting into the query SQL comments between ``/*`` and
1616 ``*/``. Inside the comments, the special strings ``[VARIABLE{variable-number}]`` is used.
1617 Be aware that the whole query minus the SQL comments must be
1618 valid by itself, otherwise you won't be able to store it as a bookmark.
1620 When you execute the bookmark, everything typed into the *Variables*
1621 input boxes on the query box page will replace the strings ``/*[VARIABLE{variable-number}]*/`` in
1624 Also remember, that everything else inside the ``/*[VARIABLE{variable-number}]*/`` string for
1625 your query will remain the way it is, but will be stripped of the ``/**/``
1626 chars. So you can use:
1628 .. code-block:: mysql
1630 /*, [VARIABLE1] AS myname */
1632 which will be expanded to
1634 .. code-block:: mysql
1636 , VARIABLE1 as myname
1638 in your query, where VARIABLE1 is the string you entered in the Variable 1 input box.
1640 A more complex example. Say you have stored
1643 .. code-block:: mysql
1645 SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE '%[VARIABLE1]%' */
1647 Say, you now enter "phpMyAdmin" as the variable for the stored query, the full
1650 .. code-block:: mysql
1652 SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE '%phpMyAdmin%'
1654 **NOTE THE ABSENCE OF SPACES** inside the ``/**/`` construct. Any spaces
1655 inserted there will be later also inserted as spaces in your query and may lead
1656 to unexpected results especially when using the variable expansion inside of a
1657 "LIKE ''" expression.
1661 6.19 How can I create simple LATEX document to include exported table?
1662 ----------------------------------------------------------------------
1664 You can simply include table in your LATEX documents,
1665 minimal sample document should look like following one (assuming you
1666 have table exported in file :file:`table.tex`):
1668 .. code-block:: latex
1671 \documentclass{article} % or any class you want
1672 \usepackage{longtable} % for displaying table
1673 \begin{document} % start of document
1674 \include{table} % including exported table
1675 \end{document} % end of document
1679 6.20 I see a lot of databases which are not mine, and cannot access them.
1680 -------------------------------------------------------------------------
1682 You have one of these global privileges: CREATE TEMPORARY TABLES, SHOW
1683 DATABASES, LOCK TABLES. Those privileges also enable users to see all the
1684 database names. So if your users do not need those privileges, you can remove
1685 them and their databases list will shorten.
1687 .. seealso:: <http://bugs.mysql.com/179>
1691 6.21 In edit/insert mode, how can I see a list of possible values for a column, based on some foreign table?
1692 ------------------------------------------------------------------------------------------------------------
1694 You have to setup appropriate links between the tables, and also setup
1695 the "display column" in the foreign table. See :ref:`faq6_6` for an
1696 example. Then, if there are 100 values or less in the foreign table, a
1697 drop-down list of values will be available. You will see two lists of
1698 values, the first list containing the key and the display column, the
1699 second list containing the display column and the key. The reason for
1700 this is to be able to type the first letter of either the key or the
1701 display column. For 100 values or more, a distinct window will appear,
1702 to browse foreign key values and choose one. To change the default
1703 limit of 100, see :config:option:`$cfg['ForeignKeyMaxLimit']`.
1708 6.22 Bookmarks: Can I execute a default bookmark automatically when entering Browse mode for a table?
1709 -----------------------------------------------------------------------------------------------------
1711 Yes. If a bookmark has the same label as a table name and it's not a
1712 public bookmark, it will be executed.
1716 6.23 Export: I heard phpMyAdmin can export Microsoft Excel files?
1717 -----------------------------------------------------------------
1719 You can use :term:`CSV` for Microsoft Excel,
1720 which works out of the box.
1722 .. versionchanged:: 3.4.5
1723 Since phpMyAdmin 3.4.5 support for direct export to Microsoft Excel version
1724 97 and newer was dropped.
1728 6.24 Now that phpMyAdmin supports native MySQL 4.1.x column comments, what happens to my column comments stored in pmadb?
1729 -------------------------------------------------------------------------------------------------------------------------
1731 Automatic migration of a table's pmadb-style column comments to the
1732 native ones is done whenever you enter Structure page for this table.
1741 6.26 How can I select a range of rows?
1742 --------------------------------------
1744 Click the first row of the range, hold the shift key and click the
1745 last row of the range. This works everywhere you see rows, for example
1746 in Browse mode or on the Structure page.
1750 6.27 What format strings can I use?
1751 -----------------------------------
1753 In all places where phpMyAdmin accepts format strings, you can use
1754 ``@VARIABLE@`` expansion and `strftime <http://php.net/strftime>`_
1755 format strings. The expanded variables depend on a context (for
1756 example, if you haven't chosen a table, you can not get the table
1757 name), but the following variables can be used:
1760 HTTP host that runs phpMyAdmin
1764 Verbose MySQL server name as defined in :config:option:`$cfg['Servers'][$i]['verbose']`
1766 Verbose MySQL server name if set, otherwise normal
1768 Currently opened database
1770 Currently opened table
1772 Columns of the currently opened table
1774 phpMyAdmin with version
1778 6.28 How can I easily edit relational schema for export?
1779 --------------------------------------------------------
1781 By clicking on the button 'toggle scratchboard' on the page where you
1782 edit x/y coordinates of those elements you can activate a scratchboard
1783 where all your elements are placed. By clicking on an element, you can
1784 move them around in the pre-defined area and the x/y coordinates will
1785 get updated dynamically. Likewise, when entering a new position
1786 directly into the input field, the new position in the scratchboard
1787 changes after your cursor leaves the input field.
1789 You have to click on the 'OK'-button below the tables to save the new
1790 positions. If you want to place a new element, first add it to the
1791 table of elements and then you can drag the new element around.
1793 By changing the paper size and the orientation you can change the size
1794 of the scratchboard as well. You can do so by just changing the
1795 dropdown field below, and the scratchboard will resize automatically,
1796 without interfering with the current placement of the elements.
1798 If ever an element gets out of range you can either enlarge the paper
1799 size or click on the 'reset' button to place all elements below each
1804 6.29 Why can't I get a chart from my query result table?
1805 --------------------------------------------------------
1807 Not every table can be put to the chart. Only tables with one, two or
1808 three columns can be visualised as a chart. Moreover the table must be
1809 in a special format for chart script to understand it. Currently
1810 supported formats can be found in the `wiki <http://wiki.phpmyadmin.ne
1811 t/pma/Charts#Data_formats_for_query_results_chart>`_.
1815 6.30 Import: How can I import ESRI Shapefiles?
1816 ----------------------------------------------
1818 An ESRI Shapefile is actually a set of several files, where .shp file
1819 contains geometry data and .dbf file contains data related to those
1820 geometry data. To read data from .dbf file you need to have PHP
1821 compiled with the dBase extension (--enable-dbase). Otherwise only
1822 geometry data will be imported.
1824 To upload these set of files you can use either of the following
1827 Configure upload directory with :config:option:`$cfg['UploadDir']`, upload both .shp and .dbf files with
1828 the same filename and chose the .shp file from the import page.
1830 Create a Zip archive with .shp and .dbf files and import it. For this
1831 to work, you need to set :config:option:`$cfg['TempDir']` to a place where the web server user can
1832 write (for example ``'./tmp'``).
1834 To create the temporary directory on a UNIX-based system, you can do:
1844 6.31 How do I create a relation in designer?
1845 --------------------------------------------
1847 To select relation, click: The display column is shown in pink. To
1848 set/unset a column as the display column, click the "Choose column to
1849 display" icon, then click on the appropriate column name.
1853 6.32 How can I use the zoom search feature?
1854 -------------------------------------------
1856 The Zoom search feature is an alternative to table search feature. It allows
1857 you to explore a table by representing its data in a scatter plot. You can
1858 locate this feature by selecting a table and clicking the :guilabel:`Search`
1859 tab. One of the sub-tabs in the :guilabel:`Table Search` page is
1860 :guilabel:`Zoom Search`.
1862 Consider the table REL\_persons in :ref:`faq6_6` for
1863 an example. To use zoom search, two columns need to be selected, for
1864 example, id and town\_code. The id values will be represented on one
1865 axis and town\_code values on the other axis. Each row will be
1866 represented as a point in a scatter plot based on its id and
1867 town\_code. You can include two additional search criteria apart from
1868 the two fields to display.
1870 You can choose which field should be
1871 displayed as label for each point. If a display column has been set
1872 for the table (see :ref:`faqdisplay`), it is taken as the label unless
1873 you specify otherwise. You can also select the maximum number of rows
1874 you want to be displayed in the plot by specifing it in the 'Max rows
1875 to plot' field. Once you have decided over your criteria, click 'Go'
1876 to display the plot.
1878 After the plot is generated, you can use the
1879 mousewheel to zoom in and out of the plot. In addition, panning
1880 feature is enabled to navigate through the plot. You can zoom-in to a
1881 certail level of detail and use panning to locate your area of
1882 interest. Clicking on a point opens a dialogue box, displaying field
1883 values of the data row represented by the point. You can edit the
1884 values if required and click on submit to issue an update query. Basic
1885 instructions on how to use can be viewed by clicking the 'How to use?'
1886 link located just above the plot.
1890 6.33 When browsing a table, how can I copy a column name?
1891 ---------------------------------------------------------
1893 Selecting the name of the column within the browse table header cell
1894 for copying is difficult, as the columns support reordering by
1895 dragging the header cells as well as sorting by clicking on the linked
1896 column name. To copy a column name, double-click on the empty area
1897 next to the column name, when the tooltip tells you to do so. This
1898 will show you an input box with the column name. You may right-click
1899 the column name within this input box to copy it to your clipboard.
1903 6.34 How can I use the Favorite Tables feature?
1904 ---------------------------------------------------------
1906 Favorite Tables feature is very much similar to Recent Tables feature.
1907 It allows you to add a shortcut for the frequently used tables of any
1908 database in the navigation panel . You can easily navigate to any table
1909 in the list by simply choosing it from the list. These tables are stored
1910 in your browser's local storage if you have not configured your
1911 `phpMyAdmin Configuration Storage`. Otherwise these entries are stored in
1912 `phpMyAdmin Configuration Storage`.
1914 IMPORTANT: In absence of `phpMyAdmin Configuration Storage`, your Favorite
1915 tables may be different in different browsers based on your different
1918 To add a table to Favorite list simply click on the `Gray` star in front
1919 of a table name in the list of tables of a Database and wait until it
1921 To remove a table from list, simply click on the `Yellow` star and
1922 wait until it turns `Gray` again.
1924 Using :config:option:`$cfg['NumFavoriteTables']` in your :file:`config.inc.php`
1925 file, you can define the maximum number of favorite tables shown in the
1926 navigation panel. Its default value is `10`.
1930 6.35 How can I use the Range search feature?
1931 ---------------------------------------------------------
1933 With the help of range search feature, one can specify a range of values for
1934 particular column(s) while performing search operation on a table from the `Search`
1937 To use this feature simply click on the `BETWEEN` or `NOT BETWEEN` operators
1938 from the operator select list in front of the column name. On choosing one of the
1939 above options, a dialog box will show up asking for the `Minimum` and `Maximum`
1940 value for that column. Only the specified range of values will be included
1941 in case of `BETWEEN` and excluded in case of `NOT BETWEEN` from the final results.
1943 Note: The Range search feature will work only `Numeric` and `Date` data type columns.
1947 6.36 What is Central columns and How can I use this feature?
1948 ------------------------------------------------------------
1950 As the name suggests, the Central columns feature enables to maintain a central list of
1951 columns per database to avoid similar name for the same data element and bring consistency
1952 of data type for the same data element. You can use the central list of columns to
1953 add an element to any table structure in that database which will save from writing
1954 similar column name and column definition.
1956 To add a column to central list, go to table structure page, check the columns you want
1957 to include and then simply click on "Add to central columns". If you want to add all
1958 unique columns from more than one table from a database then go to database structure page,
1959 check the tables you want to include and then select "Add columns to central list".
1961 To remove a column from central list, go to Table structure page, check the columns you want
1962 to remove and then simply click on "Remove from central columns". If you want to remove all
1963 columns from more than one tables from a database then go to database structure page,
1964 check the tables you want to include and then select "Remove columns from central list".
1966 To view and manage the central list, select the database you want to manage central columns
1967 for then from the top menu click on "Central columns". You will be taken to a page where
1968 you will have options to edit, delete or add new columns to central list.
1972 6.37 How can I use Improve Table structure feature?
1973 ---------------------------------------------------------
1975 Improve table structure feature helps to bring the table structure upto
1976 Third Normal Form. A wizard is presented to user which asks questions about the
1977 elements during the various steps for normalization and a new structure is proposed
1978 accordingly to bring the table into the First/Second/Third Normal form.
1979 On startup of the wizard, user gets to select upto what normal form they want to
1980 normalize the table structure.
1982 Here is an example table which you can use to test all of the three First, Second and
1985 .. code-block:: mysql
1987 CREATE TABLE `VetOffice` (
1988 `petName` varchar(64) NOT NULL,
1989 `petBreed` varchar(64) NOT NULL,
1990 `petType` varchar(64) NOT NULL,
1991 `petDOB` date NOT NULL,
1992 `ownerLastName` varchar(64) NOT NULL,
1993 `ownerFirstName` varchar(64) NOT NULL,
1994 `ownerPhone1` int(12) NOT NULL,
1995 `ownerPhone2` int(12) NOT NULL,
1996 `ownerEmail` varchar(64) NOT NULL,
1999 The above table is not in First normal Form as no primary key exists. Primary key
2000 is supposed to be (`petName`,`ownerLastName`,`ownerFirstName`) . If the primary key
2001 is chosen as suggested the resultant table won't be in Second as well as Third Normal
2002 form as the following dependencies exists.
2004 .. code-block:: mysql
2006 (OwnerLastName, OwnerFirstName) -> OwnerEmail
2007 (OwnerLastName, OwnerFirstName) -> OwnerPhone
2010 Which says, OwnerEmail depends on OwnerLastName and OwnerFirstName.
2011 OwnerPhone depends on OwnerLastName and OwnerFirstName.
2012 PetType depends on PetBreed.
2016 6.38 How can I reassign auto-incremented values?
2017 ------------------------------------------------
2019 Some users prefer their AUTO_INCREMENT values to be consecutive; this is not
2020 always the case after row deletion.
2022 Here are the steps to accomplish this. These are manual steps because they
2023 involve a manual verification at one point.
2025 * Ensure that you have exclusive access to the table to rearrange
2027 * On your primary key column (i.e. id), remove the AUTO_INCREMENT setting
2029 * Delete your primary key in Structure > indexes
2031 * Create a new column future_id as primary key, AUTO_INCREMENT
2033 * Browse your table and verify that the new increments correspond to what
2036 * Drop your old id column
2038 * Rename the future_id column to id
2040 * Move the new id column via Structure > Move columns
2044 6.39 What is the "Adjust Privileges" option when renaming, copying, or moving a database, table, column, or procedure?
2045 ----------------------------------------------------------------------------------------------------------------------
2047 When renaming/copying/moving a database/table/column/procedure,
2048 MySQL does not adjust the original privileges relating to these objects
2049 on its own. By selecting this option, phpMyAdmin will adjust the privilege
2050 table so that users have the same privileges on the new items.
2052 For example: A user 'bob'@'localhost' has a 'SELECT' privilege on a
2053 column named 'id'. Now, if this column is renamed to 'id_new'; MySQL,
2054 on its own, would **not** adjust the column privileges to the new column name.
2055 phpMyAdmin can make this adjustment for you automatically.
2059 * While adjusting privileges for a database, the privileges of all *table-related
2060 privileges*, all *column-related privileges* and all *procedure-related privileges*
2061 for the tables, columns and procedures inside that database are also adjusted
2062 to the database's new name.
2064 * Similarly, while adjusting privileges for a table, the privileges of all
2065 *column-related privileges* for the columns inside the table are also adjusted
2066 to the table's new name.
2068 Thus, if you want to replicate the database/table/column/procedure as it is
2069 while renaming/copying/moving these objects, make sure you have checked this option.
2078 7.1 I have found a bug. How do I inform developers?
2079 ---------------------------------------------------
2081 Our Bug Tracker is located at <http://sf.net/projects/phpmyadmin/> under the
2082 Bugs section. But please first discuss your bug with other users:

2087 7.2 I want to translate the messages to a new language or upgrade an existing language, where do I start?
2088 ---------------------------------------------------------------------------------------------------------
2090 Translations are very welcome and all you need to have are the
2091 language skills. The easiest way is to use our `online translation
2092 service <https://hosted.weblate.org/projects/phpmyadmin/>`_. You can check
2093 out all the possibilities to translate in the `translate section on
2094 our website <http://www.phpmyadmin.net/home_page/translate.php>`_.
2098 7.3 I would like to help out with the development of phpMyAdmin. How should I proceed?

2115 8.1 Where can I get information about the security alerts issued for phpMyAdmin?
2116 --------------------------------------------------------------------------------
2118 Please refer to <http://www.phpmyadmin.net/home_page/security.php>.
2122 8.2 How can I protect phpMyAdmin against brute force attacks?
2123 -------------------------------------------------------------
2125 If you use Apache web server, phpMyAdmin exports information about
2126 authentication to the Apache environment and it can be used in Apache
2127 logs. Currently there are two variables available:
2131 User name of currently active user (he does not have to be logged in).
2133 Status of currently active user, one of ``ok`` (user is logged in),
2134 ``mysql-denied`` (MySQL denied user login), ``allow-denied`` (user denied
2135 by allow/deny rules), ``root-denied`` (root is denied in configuration),
2136 ``empty-denied`` (empty password is denied).
2138 ``LogFormat`` directive for Apache can look like following:
2140 .. code-block:: apache
2142 LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %{userID}n %{userStatus}n" pma_combined
2144 You can then use any log analyzing tools to detect possible break-in
