7 This is a very basic document on how to setup a simple Samba4
8 server. This is aimed at developers who are already familiar with
9 Samba3 and wish to participate in Samba4 development. This is not
10 aimed at production use of Samba4.
13 Step 1: download Samba4
14 -----------------------
16 There are 2 methods of doing this:
18 method 1: "rsync -avz samba.org::ftp/unpacked/samba4 ."
20 method 2: "svn co svn://svnanon.samba.org/samba/branches/SAMBA_4_0 samba4"
22 both methods will create a directory called "samba4" in the current
23 directory. If you don't have rsync or svn then install one of them.
25 Note that the above rsync command will give you a checked out svn
26 repository. So if you also have svn you can update it to the latest
27 version at some future date using:
33 Step 2: compile Samba4
34 ----------------------
40 $ ./configure.developer -C
43 If you have gcc 3.4 or newer, then run "make pch" before "make" to
44 greatly speed up the compile process (about 5x faster).
47 Step 3: install Samba4
48 ----------------------
50 Run this as a user who have permission to write to the install
51 directory (defaults to /usr/local/samba). Use --prefix option to
52 configure above to change this.
57 Step 4: provision Samba4
58 ------------------------
60 The "provision" step sets up a basic user database.
63 $ ./setup/provision.pl --realm=YOUR.REALM --domain=YOURDOM --adminpass=SOMEPASSWORD
65 This will create a number of new 'ldb' database files in a directory
66 newdb.XXX. You need to move these to the "private" subdirectory of
67 your install. For example:
69 # mv newdb.123/*.ldb /usr/local/samba/private/
72 Step 5: Create a simple smb.conf
73 --------------------------------
75 You need to create a smb.conf file in the lib/ directory of your
76 install. The default is /usr/local/samba/lib/smb.conf. A minimal
85 The workgroup must exactly match the --domain argument you gave to provision.pl
88 Step 6: starting Samba4
89 -----------------------
91 The simplest is to just run "smbd", but as a developer you may find
92 the following more useful:
94 # smbd -i -M single -d3
96 that means "start smbd without messages in stdout, and running a
97 single process, with level 3 debugging". That mode of operation makes
98 debugging smbd with gdb particularly easy.
100 Note that now it is no longer necessary to have an instance of nmbd
101 from Samba 3 running. If you are running any smbd or nmbd processes
102 they need to be stopped before starting smbd from Samba 4.
104 Make sure you put the bin and sbin directories from your new install
105 in your $PATH. Make sure you run the right version!
108 Step 7: testing Samba4
109 ----------------------
113 $ smbclient //localhost/test -Uadministrator%SOMEPASSWORD
115 $ ./script/tests/test_posix.sh //localhost/test administrator SOMEPASSWORD
118 NOTE about filesystem support
119 -----------------------------
121 To use the advanced features of Samba4 you need a filesystem that
122 supports both the "user" and "system" xattr namespaces.
124 If you run Linux with a 2.6 kernel and ext3 this means you need to
125 include the option "user_xattr" in your /etc/fstab. For example:
127 /dev/hda3 /home ext3 user_xattr 1 1
129 You also need to compile your kernel with the XATTR and SECURITY
130 options for your filesystem. For ext3 that means you need:
132 CONFIG_EXT3_FS_XATTR=y
133 CONFIG_EXT3_FS_SECURITY=y
135 If you are running a Linux 2.6 kernel with CONFIG_IKCONFIG_PROC
136 defined you can check this with the following command:
138 $ zgrep CONFIG_EXT3_FS /proc/config.gz
140 If you don't have a filesystem with xattr support, then you can
141 simulate it by using the option:
143 posix:eadb = /usr/local/samba/eadb.tdb
145 that will place all extra file attributes (NT ACLs, DOS EAs, streams
146 etc), in that tdb. It is not efficient, and doesn't scale well, but at
147 least it gives you a choice when you don't have a modern filesystem.
149 Testing your filesystem
150 -----------------------
152 To test your filesystem support, install the 'attr' package and run
153 the following 4 commands as root:
156 # setfattr -n user.test -v test test.txt
157 # setfattr -n security.test -v test2 test.txt
158 # getfattr -d test.txt
159 # getfattr -n security.test -d test.txt
161 You should see output like this:
167 security.test="test2"
169 If you get any "Operation not supported" errors then it means your
170 kernel is not configured correctly, or your filesystem is not mounted
171 with the right options.
173 If you get any "Operation not permitted" errors then it probably means
174 you didn't try the test as root.
