 [[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)

 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.

 === 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.

 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).

 …
 ==== Generating the Trac cgi-bin directory #cgi-bin
+In order for Trac to function properly with FastCGI you need to have a `trac.fcgi` file and for mod_wsgi a `trac.wsgi` file. These are Python scripts which load the appropriate Python code. They can be generated using the `deploy` option of [TracAdmin trac-admin].
+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
+$ 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.
+Application scripts for CGI, FastCGI and mod-wsgi can be generated using the [TracAdmin trac-admin] `deploy` command:
+[[TracAdminHelp(deploy)]]
+Grant the web server execution right on scripts in the `cgi-bin` directory.
+For example, the following yields a typical directory structure:
+{{{#!sh
+$ mkdir -p /var/trac
+$ trac-admin /var/trac/<project> initenv
+$ trac-admin /var/trac/<project> deploy /var/www
+$ ls /var/www
+cgi-bin htdocs
+$ chmod ugo+x /var/www/cgi-bin/*
+}}}
 ==== Mapping Static Resources
 …
 There are two primary URL paths for static resources: `/chrome/common` and `/chrome/site`. Plugins can add their own resources, usually accessible at the `/chrome/<plugin>` path.
+A single `/chrome` alias can used if the static resources are extracted for all plugins. This means that the `deploy` command must be executed after installing or updating a plugin that provides static resources, or after modifying resources in the `$env/htdocs` directory. This is probably appropriate for most installations but may not be what you want if, for example, you wish to upload plugins through the //Plugins// administration page.
+The resources are extracted using the [TracAdmin trac-admin]` <environment> deploy` command:
+[[TracAdminHelp(deploy)]]
+The target `<directory>` will contain an `htdocs` directory with:

This means that the `deploy` command (discussed in the previous section) must be executed after installing or updating a plugin that provides static resources, or after modifying resources in the `$env/htdocs` directory. This is probably appropriate for most installations but may not be what you want if, for example, you wish to upload plugins through the //Plugins// administration page.
+The `deploy` command creates an `htdocs` directory with:
  - `common/` - the static resources of Trac
  - `site/` - a copy of the environment's `htdocs/` directory
 …
 Assuming the deployment has been done this way:
 {{{#!sh
 $ trac-admin /var/trac/env deploy /path/to/shared/trac
+$ trac-admin /var/trac/<project> deploy /var/www
 }}}
 …
 }}}
 Another alternative to aliasing `/trac/chrome/common` is having Trac generate direct links for those static resources (and only those), using the [[TracIni#trac-section| [trac] htdocs_location]] configuration setting:

 ==== Setting up the Plugin Cache
+==== Setting up the Plugin Cache #egg-cache
 Some Python plugins need to be extracted to a cache directory. By default the cache resides in the home directory of the current user. When running Trac on a Web Server as a dedicated user (which is highly recommended) who has no home directory, this might prevent the plugins from starting. To override the cache location you can set the `PYTHON_EGG_CACHE` environment variable. Refer to your server documentation for detailed instructions on how to set environment variables.
+If you setup hook scripts that call Trac, such as the Subversion post-commit hook script provided in the `/contrib` directory, make sure you define the `PYTHON_EGG_CACHE` environment variable within these scripts as well.
 == Configuring Authentication
 …
 Please refer to one of the following sections:
  * TracStandalone#UsingAuthentication if you use the standalone server, `tracd`.
  * [wiki:TracModWSGI#ConfiguringAuthentication TracModWSGI#ConfiguringAuthentication] if you use the Apache web server, with any of its front end: `mod_wsgi` of course, but the same instructions applies also for `mod_python`, `mod_fcgi` or `mod_fastcgi`.
  * TracFastCgi if you are using another web server with FCGI support, such as Cherokee, Lighttpd, !LiteSpeed, nginx.
 The following document also contains some useful information for beginners: [trac:TracAuthenticationIntroduction].

+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.
