 [[TracGuideToc]]
 Trac is written in the Python programming language and needs a database, [http://sqlite.org/ SQLite], [http://www.postgresql.org/ PostgreSQL], or [http://mysql.com/ MySQL]. For HTML rendering, Trac uses the [http://genshi.edgewall.org Genshi] templating system.
 Since version 0.12, Trac can also be localized, and there is probably a translation available in your language. If you want to use the Trac interface in other languages, then make sure you have installed the optional package [#OtherPythonPackages Babel]. Pay attention to the extra steps for localization support in the [#InstallingTrac Installing Trac] section below. Lacking Babel, you will only get the default English version.

 == Dependencies
 === Mandatory Dependencies
 To install Trac, the following software packages must be installed:
  * [http://www.python.org/ Python], version >= 2.5 and < 3.0
    (note that we dropped the support for Python 2.4 in this release)
+ * [http://www.python.org/ Python], version >= 2.6 and < 3.0
+   (note that we dropped the support for Python 2.5 in this release)
  * [http://pypi.python.org/pypi/setuptools setuptools], version >= 0.6
  * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.6
 …
 ==== For the SQLite database #ForSQLite
 As you must be using Python 2.5, 2.6 or 2.7, you already have the SQLite database bindings bundled with the standard distribution of Python: the `sqlite3` module.
+As you must be using Python 2.6 or 2.7, you already have the SQLite database bindings bundled with the standard distribution of Python (the `sqlite3` module).
 Optionally, you may install a newer version of [http://pypi.python.org/pypi/pysqlite pysqlite] than the one provided by the Python distribution. See [trac:PySqlite#ThePysqlite2bindings PySqlite] for details.

 Trac works well with MySQL, provided you follow the guidelines:
  * [http://mysql.com/ MySQL] or [http://mariadb.org/ MariaDB], version 5.0 or later
+ * [http://mysql.com/ MySQL], version 5.0 or later

 Given the caveats and known issues surrounding MySQL, read the [trac:MySqlDb] page before creating the database.

 === Optional Dependencies
+==== Version Control System
+===== Subversion
+ * [http://subversion.apache.org/ Subversion], 1.5.x or later and the '''corresponding''' Python bindings. Older versions starting from 1.0, like 1.2.4, 1.3.2 or 1.4.2, etc. may still work. For troubleshooting information, check the [trac:TracSubversion#Troubleshooting TracSubversion] page.

 There are [http://subversion.apache.org/packages.html pre-compiled SWIG bindings] available for various platforms. (Good luck finding precompiled SWIG bindings for any Windows package at that listing. [trac:TracSubversion] points you to [http://alagazam.net Alagazam], which works for me under Python 2.6.)
+Note that Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], neither does it work yet with the newer `ctype`-style bindings.
+'''Note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently [trac:ticket:493 not supported].
+===== Git
+ * [http://git-scm.com/ Git] 1.5.6 or later.
+More information is available on the [trac:TracGit] page.

 Please refer to the documentation of these packages to find out how they are best installed. In addition, most of the [trac:TracInstallPlatforms platform-specific instructions] also describe the installation of the dependencies. Keep in mind however that the information there probably concern older versions of Trac than the one you're installing.

 == Installing Trac
 …
 The [TracAdmin trac-admin] command-line tool, used to create and maintain [TracEnvironment project environments], as well as the [TracStandalone tracd] standalone server are installed along with Trac. There are several methods for installing Trac.
 It is assumed throughout this guide that you have elevated permissions as the `root` user, or by prefixing commands with `sudo`. The umask `0022` should be used for a typical installation on a Unix-based platform.

 pip will automatically resolve all dependencies (like Genshi, pygments, etc.), download the latest packages from pypi.python.org and create a self contained installation in `/opt/user/trac`.
 All commands (`tracd`, `trac-admin`) are available in `/opt/user/trac/bin`. This can also be leveraged for `mod_python` (using `PythonHandler` directive) and `mod_wsgi` (using `WSGIDaemonProcess` directive).

 Additionally, you can install several Trac plugins (listed [https://pypi.python.org/pypi?:action=browse&show=all&c=516 here]) through pip.
 === From source
 Using the python-typical setup at the top of the source directory also works. You can obtain the source for a .tar.gz or .zip file corresponding to a release (e.g. `Trac-1.0.tar.gz`) from the [trac:TracDownload] page, or you can get the source directly from the repository. See [trac:TracRepositories#OfficialSubversionrepository TracRepositories] for details.

 Alternatively, you can run `bdist_egg` and copy the .egg from `dist/` to the place of your choice, or you can create a Windows installer (`bdist_wininst`).
 === Using installer
 On Windows Trac can be installed using the exe installers available on the [trac:TracDownload] page. Installers are available for the 32 and 64 bit versions of Python. Make sure to use the installer that matches the architecture of your Python installation.

 == Creating a Project Environment
 A [TracEnvironment Trac environment] is the backend where Trac stores information like wiki pages, tickets, reports, settings, etc. An environment is basically a directory that contains a human-readable [TracIni configuration file], and other files and directories.

 Finally, make sure the user account under which the web front-end runs will have '''write permissions''' to the environment directory and all the files inside. This will be the case if you run `trac-admin ... initenv` as this user. If not, you should set the correct user afterwards. For example on Linux, with the web server running as user `apache` and group `apache`, enter:
 {{{#!sh
 $ chown -R apache.apache /path/to/myproject
 }}}
 The actual username and groupname of the Apache server may not be exactly `apache`, and are specified in the Apache configuration file by the directives `User` and `Group` (if Apache `httpd` is what you use).

 There is, however, a bit of a chicken-and-egg problem. The [TracAdmin trac-admin] command requires an existing environment to function, but complains if the deploy directory already exists. This is a problem, because environments are often stored in a subdirectory of the deploy. The solution is to do something like this:
 {{{#!sh
+$ mkdir -p /usr/share/trac/projects/my-project
+$ trac-admin /usr/share/trac/projects/my-project initenv
+$ trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy

+}}}

+trac-admin /usr/share/trac/projects/my-project initenv
+trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy
+mv /tmp/deploy/* /usr/share/trac
+}}}
 Don't forget to check that the web server has the execution right on scripts in the `/usr/share/trac/cgi-bin` directory.

+This user will have an "Admin" entry menu that will allow you to administrate your Trac project.
+== Finishing the install
+=== Enable version control components
+Support for version control systems is provided by optional components in Trac and the components are disabled by default //(since 1.0)//. Subversion and Git must be explicitly enabled if you wish to use them. See TracRepositoryAdmin for more details.
+The version control systems are enabled by adding the following to the `[components]` section of your [TracIni#components-section trac.ini], or enabling the components in the "Plugins" admin panel:
+{{{#!ini
+[components]
+tracopt.versioncontrol.svn.* = enabled
+}}}
+{{{#!ini
+[components]
+tracopt.versioncontrol.git.* = enabled
+}}}
+After enabling the components, repositories can be configured through the //Repositories// admin panel or by editing [TracIni#repositories-section trac.ini]. Automatic changeset references can be inserted as ticket comments by configuring [TracRepositoryAdmin#Automaticchangesetreferencesintickets CommitTicketUpdater].
+=== Using Trac
+This user will have an //Admin// navigation item that directs to pages for administering your Trac project.
+== Configuring Trac
+TracRepositoryAdmin provides information on configuring version control repositories for your project.
+== Using Trac
 Once you have your Trac site up and running, you should be able to create tickets, view the timeline, browse your version control repository if configured, etc.
