== Samba OS Requirements == |
|||
Most users are running [[Distribution-specific_Package_Installation|packages shipped with their distribution]] or from 3rd parties, such as SerNet ([http://www.samba.plus Samba+]/[http://www.samba.plus/older-packages/ Enterprise]). However, in some situations you decide to compile Samba yourself, like |
|||
Because of the constantly changing and ever expanding nature of Linux, the [[Samba_4/OS_Requirements| Samba AD DC OS requirements]] page is now self contained. |
|||
* outdated packages are shipped with your distribution |
|||
This page not only includes the required packages for a successful Samba AD DC deployment, but also the required file system features. Please consider that page as a prerequisite to a successful Samba AD DC setup. |
|||
* no packages are available for your distribution or OS |
|||
* you want to apply a patch from a developer to fix a problem before a new version is released |
|||
Compiling Samba requires only a few steps: |
|||
== Step 1: Download Samba == |
|||
* Install all dependencies. See [[Package Dependencies Required to Build Samba]]. |
|||
* Download the sources from [https://www.samba.org samba.org] |
|||
* Extract the source package |
|||
* Run |
|||
:<code>./configure</code> |
|||
:<code>make</code> |
|||
:<code>sudo make install</code> |
|||
You can run most of the required steps in this documentation without root privileges. If root permissions are required, the command is prefixed with <code>sudo</code>. Please see the <code>sudo (8)</code> manual page and your distribution documentation how to set up <code>sudo</code>. |
|||
Currently, there are two methods to download the current Samba sources, either as a tarball of the latest stable release, or a development version via git. If you hope to work with the team on a development version to resolve issues you may hit via code changes, we recommend using the git method for downloading Samba, as it makes getting updates easier, and also allows you to integrate test patches from Samba developers more easily in case of problems. |
|||
The following documentation is valid for every type of Samba installation, like an Active Directory (AD) domain controller (DC), a domain member (AD and NT4 domain), an NT4 PDC, and standalone server. |
|||
In the following examples we will assume that your top-level source is named <tt>samba-master</tt>, <tt>samba-v4-0-stable</tt>, or <tt>samba-v4-0-test</tt> depending on which head you're downloading from. If you downloaded a tarball this will instead be based on the name of the tarball downloaded (e.g. <tt>samba-4.0.0</tt> for the tarball samba-4.0.0.tar.gz). Also note that in the <tt>master</tt> branch the |
|||
Samba 4 code in our current git tree is now located in the top level directory. |
|||
=== Downloading a tarball === |
|||
If you wish to use a released version of Samba 4.0, you can download the latest Samba 4.0 tarball from [http://ftp.samba.org/pub/samba/ the Samba website] |
|||
=== Downloading via git === |
|||
Git allows you to download the source tree via either the <tt>git</tt> or <tt>http</tt> protocols. In general, the <tt>git</tt> protocol is the preferred choice since it compresses the data being transferred. To download the source tree via <tt>git</tt>, run the following command: |
|||
= Samba Operating System Requirements = |
|||
$ git clone git://git.samba.org/samba.git samba-master |
|||
To build Samba, install all required libraries and tools first. See [[Operating_System_Requirements|Operating System Requirements]]. |
|||
Alternatively, if you prefer to use the <tt>http</tt> protocol, run the following command: |
|||
$ git clone http://gitweb.samba.org/samba.git samba-master |
|||
Either command will create a directory called <tt>samba-master</tt> in the current |
|||
directory. This holds a checkout of the 'master' development branch. |
|||
= Obtaining Samba = |
|||
== Stable Version (Recommended) == |
|||
Always download the latest version of Samba from https://www.samba.org/. |
|||
Samba maintains three series of minor versions. For a maximum of security and stability, the Samba team recommends that you only install the latest available version of a series. Older versions do not contain the latest bug and security fixes. For further information, see [[Samba_Release_Planning|Samba Release Planning]]. |
|||
{{Imbox |
|||
| type = note |
|||
| text = In case if you are asking for help on the [https://lists.samba.org/mailman/listinfo/samba Samba Mailing List] and not running the latest version, the list members usually advice you to update your installation first to verify that the bug has not been fixed in the meantime. |
|||
}} |
|||
To download, use a tool like <code>wget</code>. For example: |
|||
$ wget <nowiki>https://download.samba.org/pub/samba/stable/samba-x.y.z.tar.gz</nowiki> |
|||
== Development Versions == |
|||
'''Do not use a development version in production!''' |
|||
To download a development version, use <code>git</code> to clone the repository. For details, see [[Using Git for Samba Development]]. |
|||
Before a new major version is released, the Samba team publishes release candidates for testing purposes. You can download release candidates from https://download.samba.org/pub/samba/rc/ |
|||
= Extracting the Source Package = |
|||
To extract the downloaded source package, run: |
|||
$ tar -zxf samba-x.y.z.tar.gz |
|||
= configure = |
|||
Change into the directory with the extracted sources: |
|||
$ cd samba-x.y.z/ |
|||
The <code>configure</code> script is located in the root of the sources directory. The main purpose of the script is to create a <code>Makefile</code> which is used by the command <code>make</code>. The <code>configure</code> script enables you to set various options, like installation paths. If you do not want to [[#Customizing_the_Configure_Options|customize]] any paths, and enable or disable parts of Samba, run the following command without any option: |
|||
$ ./configure |
|||
If the command fails, read the error message and fix the problem. One common problem are missing dependencies. For details, see [[Operating_System_Requirements|Operating System Requirements]]. |
|||
The following example shows the output, if the <code>configure</code> script cannot find the GnuTLS headers: |
|||
Checking for gnutls >= 1.4.0 and broken versions : not found |
|||
/usr/src/samba-x.y.z/source4/lib/tls/wscript:37: error: Building the AD DC requires |
|||
GnuTLS (eg libgnutls-dev, gnutls-devel) for ldaps:// support and for the BackupKey protocol |
|||
If the <code>configure</code> script exits without an error, you see the following output: |
|||
'configure' finished successfully (1m2.432s) |
|||
Continue with the <code>[[#make|make]]</code> step, if no error has occurred. |
|||
== Customizing the Configure Options == |
|||
While running the <code>configure</code> script without any options is sufficient to build Samba, you can customize installation paths and enable or disable features. To display the list of options, run: |
|||
$ ./configure --help |
|||
The output shows two major kind of options: |
|||
* [[#enable.2Fdisable.2Fwith.2Fwithout_options|--enable/--disable and --with/--without options]] |
|||
* [[#Installation_directories|installation directories]] |
|||
=== enable/disable/with/without Options === |
|||
The <code>configure</code> script provides several <code>--enable-*</code> / <code>-disable-*</code> and <code>--with-*</code> / <code>--without-*</code> options. They allow you to enable and disable features. Each option you can turn to its opposite if you use <code>--enable</code> instead of <code>--disable</code>, <code>--with</code> instead of <code>--without</code>, and the other way around. |
|||
* <u>Example 1:</u> Disable CUPS support (enabled by default): |
|||
--enable-cups |
|||
Build with cups support (default=yes) |
|||
:If you do not require CUPS support, disable the feature passing the <code>--disable-cups</code> option to the <code>configure</code> command: |
|||
$ ./configure ... --disable-cups |
|||
* <u>Example 2:</u> Compile Samba without AD DC capabilities: |
|||
--without-ad-dc |
|||
disable AD DC functionality (enables Samba 4 client and Samba 3 code base). |
|||
: If you build Samba for a host that should not act as an AD DC, you can disable this feature passing the <code>--without-ad-dc</code> option to the <code>configure</code> command: |
|||
$ ./configure ... --without-ad-dc |
|||
* <u>Example 3:</u> Build Samba with debug information: |
|||
$ ./configure ... --enable-debug |
|||
'''Warning: Do not enable or disable features if you have not fully understood the cause of the option! Changing options can prevent your Samba installation from working as expected!''' |
|||
=== Installation Directories === |
|||
If you use the default settings, the binaries, configuration files, libraries, and other files are installed in the <code>/usr/local/samba/</code> directory. This enables you to keep the complete Samba installation in one location. However, you can specify individual paths. For example: |
|||
* To install the daemon binaries like <code>smbd</code> and <code>samba</code> in the <code>/sbin/</code> directory instead of </code>/usr/local/samba/sbin/</code>, run: |
|||
$ ./configure ... --sbindir=/sbin/ |
|||
* To set the default path to the </code>smb.conf</code> file to <code>/etc/samba/</code> instead of </code>/usr/local/samba/etc/</code>, run: |
|||
$ ./configure ... --sysconfdir=/etc/samba/ |
|||
* To store the Samba man pages in the <code>/usr/share/man/</code> directory, run: |
|||
$ ./configure ... --mandir=/usr/share/man/ |
|||
= make = |
|||
To start the compilation, run |
|||
$ make |
|||
The <code>make</code> command is able to run multiple jobs in parallel. For example, to run 2 <code>make</code> sub-tasks at the same time, run: |
|||
$ make -j 2 |
|||
If the compilation exits without an error, you see the following output: |
|||
Waf: Leaving directory `/usr/src/samba-x.y.z/bin' |
|||
'build' finished successfully (9m3.667s) |
|||
= make test (Optional) = |
|||
This optional step runs the Samba self test suite. |
|||
$ make test |
|||
{{Imbox |
|||
| type = note |
|||
| text = You can only run the self test suite, if you built Samba using the <code>--enable-selftest</code> option. |
|||
}} |
|||
= make install = |
|||
To install the compiled software, you require <code>root</code> permissions to write to the destination directories and set the correct permissions. |
|||
To install Samba, run: |
|||
$ sudo make install |
|||
If the installation exits without an error, you see the following output: |
|||
Waf: Leaving directory `/usr/src/samba-x.y.z/bin' |
|||
'install' finished successfully (18.243s) |
|||
= Adding Samba Commands to the $PATH Variable = |
|||
If you built Samba, add the directories containing the commands to the beginning of your <code>$PATH</code> variable. For example: |
|||
'''If you are using the checkout for a production installation you should use the following git branches:''' |
|||
export PATH=/usr/local/samba/bin/:/usr/local/samba/sbin/:$PATH |
|||
* 'v4-0-stable' (which contains the latest stable 4.0.x release) |
|||
To permanently update your <code>$PATH</code>, see your distribution's documentation. |
|||
$ git clone -b v4-0-stable git://git.samba.org/samba.git samba-v4-0-stable |
|||
'''or''' |
|||
* 'v4-0-test' (which contains the patches scheduled for the next stable 4.0.x release) |
|||
$ git clone -b v4-0-test git://git.samba.org/samba.git samba-v4-0-test |
|||
==== Updating via git ==== |
|||
= Upgrading a Self-compiled Samba Installation = |
|||
If you already have downloaded the source tree via <tt>git</tt> and want to update the tree to the latest version, run the following command in your <tt>samba-master</tt> directory: |
|||
To update a self-compiled Samba installation, run the same steps like for a new installation while using the same <code>configure</code> options. |
|||
$ git pull |
|||
If you get an error like this: |
|||
fatal: Unable to create '[...]/samba_master/.git/index.lock': File exists. |
|||
Run the command below to reset your tree. |
|||
If you are having trouble compiling the source, it may be due to stale files. You can reset your <tt>git</tt> tree to correct these errors. To reset your <tt>git</tt> tree, run the following command in your <tt>samba-master</tt> directory: |
|||
$ git clean -x -f -d |
|||
== Step 2: Compile Samba == |
|||
= Applying a Patch = |
|||
To build Samba, run the following command in your <tt>samba-master</tt> directory: |
|||
Some situations require that you apply a patch to Samba. For example, a bug has been fixed and you you cannot wait until the new Samba version is released. To apply the patch to the Samba sources, run: |
|||
$ cd samba-master |
|||
$ ./configure |
|||
$ make |
|||
* Change into the Samba sources directory. |
|||
The above command will setup Samba to install in <tt>/usr/local/samba</tt>. |
|||
$ cd samba-x.y.z/ |
|||
* Download the patch. For example: |
|||
* If you want Samba to install in a different directory, then you should use the <tt>--prefix</tt> option to <tt>configure</tt>. |
|||
$ wget -O /tmp/patch.txt <nowiki>https://bugzilla.samba.org/attachment.cgi?id=...</nowiki> |
|||
* Apply the patch to the sources: |
|||
* We recommend using <tt>--enable-debug --enable-selftest</tt> for Samba is that it will include extra debug information that will help us diagnose problems in case of failures, and will also allow you to run our selftest <tt>make test</tt> to validate that Samba can behave correctly on your platform. Both of these are however, entirely '''optional'''. |
|||
$ patch -p 1 < /tmp/patch.txt |
|||
* Recompile and install Samba. See [[Updating_Samba|Updating Samba]]. |
|||
== Step 3: Install Samba == |
|||
To install Samba, run the following command in your <tt>samba-master</tt> directory: |
|||
$ make install |
|||
Note that this must be run as a user who has permission to write to the install directory, which defaults to <tt>/usr/local/samba</tt>. See [[#Step 2: Compile Samba4|Step 2: Compile Samba ]] for instructions on how to change the install directory. |
|||
== Upgrading a source version == |
|||
= Additional information = |
|||
To upgrade to the latest Samba version from a previous Samba release, you must first download the latest tarball, or use the git tree. If using git, you may either do a full download of the latest git tree as described in the [http://wiki.samba.org/index.php/Samba4/HOWTO#Downloading_via_git Downloading via git] section, or you may upgrade your current git tree as described in the [http://wiki.samba.org/index.php/Samba4/HOWTO#Updating_via_git Updating via git] section.

Revision as of 16:33, 27 April 2017
Introduction
Most users are running packages shipped with their distribution or from 3rd parties, such as SerNet (Samba+/Enterprise). However, in some situations you decide to compile Samba yourself, like
- outdated packages are shipped with your distribution
- no packages are available for your distribution or OS
- you want to apply a patch from a developer to fix a problem before a new version is released
Compiling Samba requires only a few steps:
- Install all dependencies. See Package Dependencies Required to Build Samba.
- Download the sources from samba.org
- Extract the source package
- Run
./configure
make
sudo make install
You can run most of the required steps in this documentation without root privileges. If root permissions are required, the command is prefixed with sudo
. Please see the sudo (8)
manual page and your distribution documentation how to set up sudo
.
The following documentation is valid for every type of Samba installation, like an Active Directory (AD) domain controller (DC), a domain member (AD and NT4 domain), an NT4 PDC, and standalone server.
Samba Operating System Requirements
To build Samba, install all required libraries and tools first. See Operating System Requirements.
Obtaining Samba
Stable Version (Recommended)
Always download the latest version of Samba from https://www.samba.org/.
Samba maintains three series of minor versions. For a maximum of security and stability, the Samba team recommends that you only install the latest available version of a series. Older versions do not contain the latest bug and security fixes. For further information, see Samba Release Planning.
In case if you are asking for help on the Samba Mailing List and not running the latest version, the list members usually advice you to update your installation first to verify that the bug has not been fixed in the meantime. |
To download, use a tool like wget
. For example:
$ wget https://download.samba.org/pub/samba/stable/samba-x.y.z.tar.gz
Development Versions
Do not use a development version in production!
To download a development version, use git
to clone the repository. For details, see Using Git for Samba Development.
Before a new major version is released, the Samba team publishes release candidates for testing purposes. You can download release candidates from https://download.samba.org/pub/samba/rc/
Extracting the Source Package
To extract the downloaded source package, run:
$ tar -zxf samba-x.y.z.tar.gz
configure
Change into the directory with the extracted sources:
$ cd samba-x.y.z/
The configure
script is located in the root of the sources directory. The main purpose of the script is to create a Makefile
which is used by the command make
. The configure
script enables you to set various options, like installation paths. If you do not want to customize any paths, and enable or disable parts of Samba, run the following command without any option:
$ ./configure
If the command fails, read the error message and fix the problem. One common problem are missing dependencies. For details, see Operating System Requirements.
The following example shows the output, if the configure
script cannot find the GnuTLS headers:
Checking for gnutls >= 1.4.0 and broken versions : not found /usr/src/samba-x.y.z/source4/lib/tls/wscript:37: error: Building the AD DC requires GnuTLS (eg libgnutls-dev, gnutls-devel) for ldaps:// support and for the BackupKey protocol
If the configure
script exits without an error, you see the following output:
'configure' finished successfully (1m2.432s)
Continue with the make
step, if no error has occurred.
Customizing the Configure Options
While running the configure
script without any options is sufficient to build Samba, you can customize installation paths and enable or disable features. To display the list of options, run:
$ ./configure --help
The output shows two major kind of options:
enable/disable/with/without Options
The configure
script provides several --enable-*
/ -disable-*
and --with-*
/ --without-*
options. They allow you to enable and disable features. Each option you can turn to its opposite if you use --enable
instead of --disable
, --with
instead of --without
, and the other way around.
- Example 1: Disable CUPS support (enabled by default):
--enable-cups Build with cups support (default=yes)
- If you do not require CUPS support, disable the feature passing the
--disable-cups
option to theconfigure
command:
$ ./configure ... --disable-cups
- Example 2: Compile Samba without AD DC capabilities:
--without-ad-dc disable AD DC functionality (enables Samba 4 client and Samba 3 code base).
- If you build Samba for a host that should not act as an AD DC, you can disable this feature passing the
--without-ad-dc
option to theconfigure
command:
$ ./configure ... --without-ad-dc
- Example 3: Build Samba with debug information:
$ ./configure ... --enable-debug
Warning: Do not enable or disable features if you have not fully understood the cause of the option! Changing options can prevent your Samba installation from working as expected!
Installation Directories
If you use the default settings, the binaries, configuration files, libraries, and other files are installed in the /usr/local/samba/
directory. This enables you to keep the complete Samba installation in one location. However, you can specify individual paths. For example:
- To install the daemon binaries like
smbd
andsamba
in the/sbin/
directory instead of /usr/local/samba/sbin/, run:
$ ./configure ... --sbindir=/sbin/
- To set the default path to the smb.conf file to
/etc/samba/
instead of /usr/local/samba/etc/, run:
$ ./configure ... --sysconfdir=/etc/samba/
- To store the Samba man pages in the
/usr/share/man/
directory, run:
$ ./configure ... --mandir=/usr/share/man/
make
To start the compilation, run
$ make
The make
command is able to run multiple jobs in parallel. For example, to run 2 make
sub-tasks at the same time, run:
$ make -j 2
If the compilation exits without an error, you see the following output:
Waf: Leaving directory `/usr/src/samba-x.y.z/bin' 'build' finished successfully (9m3.667s)
make test (Optional)
This optional step runs the Samba self test suite.
$ make test
You can only run the self test suite, if you built Samba using the --enable-selftest option. |
make install
To install the compiled software, you require root
permissions to write to the destination directories and set the correct permissions.
To install Samba, run:
$ sudo make install
If the installation exits without an error, you see the following output:
Waf: Leaving directory `/usr/src/samba-x.y.z/bin' 'install' finished successfully (18.243s)
Adding Samba Commands to the $PATH Variable
If you built Samba, add the directories containing the commands to the beginning of your $PATH
variable. For example:
export PATH=/usr/local/samba/bin/:/usr/local/samba/sbin/:$PATH
To permanently update your $PATH
, see your distribution's documentation.
Upgrading a Self-compiled Samba Installation
To update a self-compiled Samba installation, run the same steps like for a new installation while using the same configure
options.
Applying a Patch
Some situations require that you apply a patch to Samba. For example, a bug has been fixed and you you cannot wait until the new Samba version is released. To apply the patch to the Samba sources, run:
- Change into the Samba sources directory.
$ cd samba-x.y.z/
- Download the patch. For example:
$ wget -O /tmp/patch.txt https://bugzilla.samba.org/attachment.cgi?id=...
- Apply the patch to the sources:
$ patch -p 1 < /tmp/patch.txt
- Recompile and install Samba. See Updating Samba.
Additional information
Viewing Built Options of an Existing Installation
To display the options used to built Samba, run
$ smbd -b
