    54Trac 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.
    65
    7 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.

    1715=== Mandatory Dependencies
    18 
    1916To install Trac, the following software packages must be installed:
    2017
    21  * [http://www.python.org/ Python], version >= 2.5 and < 3.0
    22    (note that we dropped the support for Python 2.4 in this release)
     18 * [http://www.python.org/ Python], version >= 2.6 and < 3.0
     19   (note that we dropped the support for Python 2.5 in this release)
    2320 * [http://pypi.python.org/pypi/setuptools setuptools], version >= 0.6
    2421 * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.6
     
    2825==== For the SQLite database #ForSQLite
    2926
    30 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.
     27As 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).
    3128
    3229Optionally, 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.
     
    4441Trac works well with MySQL, provided you follow the guidelines:
    4542
    46  * [http://mysql.com/ MySQL] or [http://mariadb.org/ MariaDB], version 5.0 or later
     43 * [http://mysql.com/ MySQL], version 5.0 or later
    4744 * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.2 or later
    4845
    49 Given the caveats and known issues surrounding MySQL, read the [trac:MySqlDb] page before creating the database.

    5148=== Optional Dependencies
    5249
    53 ==== Version Control System
    54 
    55 ===== Subversion
    56  * [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.
     50==== Subversion
     51
     52[http://subversion.apache.org/ Subversion], 1.6.x or later and the '''''corresponding''''' Python bindings.
    5753
    5854There 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.)
    5955
    60 Note that Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], neither does it work yet with the newer `ctype`-style bindings.
    61 
    62 '''Note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently [trac:ticket:493 not supported].
    63 
    64 ===== Git
    65  * [http://git-scm.com/ Git] 1.5.6 or later.
    66 
    67 More information is available on the [trac:TracGit] page.
    68 
    69 ===== Others
    70 
    71 Support for other version control systems is provided via third-parties. See [trac:PluginList#VersionControlSystems] and [trac:VersionControlSystem].

    162153Additionally, you can install several Trac plugins (listed [https://pypi.python.org/pypi?:action=browse&show=all&c=516 here]) through pip.
    163154
    164155=== From source
    165 
    166156Using 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.

    223213
    224 [TracAdmin trac-admin] will prompt you for the information it needs to create the environment, such as the name of the project and the [TracEnvironment#DatabaseConnectionStrings database connection string]. If you're not sure what to specify for one of these options, just press `<Enter>` to use the default value.
    225 
    226 Using the default database connection string in particular will always work as long as you have SQLite installed.
    227 For the other [trac:DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
    228 
    229 Since 0.12, Trac doesn't ask for a [TracEnvironment#SourceCodeRepository source code repository] anymore when creating an environment. Repositories can be [TracRepositoryAdmin added] afterwards, and support for specific version control systems is disabled by default.
    230 
    231 Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file.

    237224Finally, 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:

     241
     242To be effective system-wide a shell script with the `export` statement may be added to `/etc/profile.d`. To be effective for a user session the `export` statement may be added to `~/.profile`.

    265 To be effective system-wide a shell script with the `export` statement may be added to `/etc/profile.d`.  !Ubuntu/Debian users can add the `export` statement to `/etc/apache2/envvars`. !RedHat/CentOS/Fedora users can add the `export` statement to `/etc/sysconfig/httpd`. To be effective for a user session the `export` statement may be added to `~/.profile`.
    266 {{{#!sh
    267 export PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1
    268 }}}
    269 
    270 Alternatively, the variable can be set in the shell before executing `tracd`:
    271 {{{#!sh
    272 $ PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1 tracd --port 8000 /path/to/myproject
    273 }}}
    274265}}}
    275266
     
    278269Trac provides various options for connecting to a "real" web server:
    279270 - [TracFastCgi FastCGI]
    280  - [wiki:TracModWSGI mod_wsgi]
    281  - [TracModPython mod_python]
    282  - //[TracCgi CGI]: should not be used, as it degrades performance//
     271 - [wiki:TracModWSGI Apache with mod_wsgi]
     272 - [TracModPython Apache with mod_python]
     273 - [TracCgi CGI] //(should not be used, as the performance is far from optimal)//
    283274
    284275Trac also supports [trac:TracOnWindowsIisAjp AJP] which may be your choice if you want to connect to IIS. Other deployment scenarios are possible: [trac:TracNginxRecipe nginx], [http://projects.unbit.it/uwsgi/wiki/Example#Traconapacheinasub-uri uwsgi], [trac:TracOnWindowsIisIsapi Isapi-wsgi] etc.
     
    286277==== Generating the Trac cgi-bin directory #cgi-bin
    287278
    288 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].
    289 
    290 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:
    291 {{{#!sh
    292 $ mkdir -p /usr/share/trac/projects/my-project
    293 $ trac-admin /usr/share/trac/projects/my-project initenv
    294 $ trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy
    295 $ mv /tmp/deploy/* /usr/share/trac
    296 }}}
    297 
    298 Don't forget to check that the web server has the execution right on scripts in the `/usr/share/trac/cgi-bin` directory.
     279Application scripts for CGI, FastCGI and mod-wsgi can be generated using the [TracAdmin trac-admin] `deploy` command:
     280[[TracAdminHelp(deploy)]]
     281
     282Grant the web server execution right on scripts in the `cgi-bin` directory.
     283
     284For example, the following yields a typical directory structure:
     285{{{#!sh
     286$ mkdir -p /var/trac
     287$ trac-admin /var/trac/<project> initenv
     288$ trac-admin /var/trac/<project> deploy /var/www
     289$ ls /var/www
     290cgi-bin htdocs
     291$ chmod ugo+x /var/www/cgi-bin/*
     292}}}
    299293
    300294==== Mapping Static Resources
    301295
    302 Out of the box, Trac will pass static resources such as style sheets or images through itself. For anything but a tracd only based deployment, this is far from optimal as the web server could be set up to directly serve those static resources. For CGI setup, this is '''highly undesirable''' as it causes abysmal performance.
    303 
    304 Web servers such as [http://httpd.apache.org/ Apache] allow you to create "Aliases" to resources, giving them a virtual URL that doesn't necessarily reflect the layout of the servers file system. We also can map requests for static resources directly to the directory on the file system, avoiding processing these requests by Trac itself.
    305 
    306 There are two primary URL paths for static resources - `/chrome/common` and `/chrome/site`. Plugins can add their own resources, usually accessible by `/chrome/<plugin>` path, so its important to override only known paths and not try to make universal `/chrome` alias for everything.
    307 
    308 Note that in order to get those static resources on the filesystem, you need first to extract the relevant resources from Trac using the [TracAdmin trac-admin]` <environment> deploy` command:
    309 [[TracAdminHelp(deploy)]]
    310 
    311 The target `<directory>` will then contain an `htdocs` directory with:
    312  - `site/` - a copy of the environment's directory `htdocs/`
    313  - `common/` - the static resources of Trac itself
    314  - `<plugins>/` - one directory for each resource directory managed by the plugins enabled for this environment
    315 
    316 ===== Example: Apache and `ScriptAlias` #ScriptAlias-example
    317 
    318 Assuming the deployment has been done this way:
    319 {{{#!sh
    320 $ trac-admin /var/trac/env deploy /path/to/shared/trac
    321 }}}
    322 
    323 Add the following snippet to Apache configuration ''before'' the `ScriptAlias` or `WSGIScriptAlias` (which map all the other requests to the Trac application), changing paths to match your deployment:
     296Without additional configuration, Trac will handle requests for static resources such as stylesheets and images. For anything other than a TracStandalone deployment, this is not optimal as the web server can be set up to directly serve the static resources. For CGI setup, this is '''highly undesirable''' as it causes abysmal performance.
     297
     298Web servers such as [http://httpd.apache.org/ Apache] allow you to create //Aliases// to resources, giving them a virtual URL that doesn't necessarily reflect their location on the file system. We can map requests for static resources directly to directories on the file system, to avoid Trac processing the requests.
     299
     300There 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.
     301
     302A single `/chrome` alias can used if the static resources are extracted for all plugins. 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 `$env/htdocs` directory. This is probably appropriate for most installations but may not be what you want if, for example, you wish to upload plugins through the //Plugins// administration page.
     303
     304The `deploy` command creates an `htdocs` directory with:
     305 - `common/` - the static resources of Trac
     306 - `site/` - a copy of the environment's `htdocs/` directory
     307 - `shared` - the static resources shared by multiple Trac environments, with a location defined by the `[inherit]` `htdocs_dir` option
     308 - `<plugin>/` - one directory for each resource directory provided by the plugins enabled for this environment
     309
     310The example that follows will create a single `/chrome` alias. If that isn't the correct approach for your installation you simply need to create more specific aliases:
    324311{{{#!apache
    325312Alias /trac/chrome/common /path/to/trac/htdocs/common
    326313Alias /trac/chrome/site /path/to/trac/htdocs/site
     314Alias /trac/chrome/shared /path/to/trac/htdocs/shared
     315Alias /trac/chrome/<plugin> /path/to/trac/htdocs/<plugin>
     316}}}
     317
     318===== Example: Apache and `ScriptAlias` #ScriptAlias-example
     319
     320Assuming the deployment has been done this way:
     321{{{#!sh
     322$ trac-admin /var/trac/<project> deploy /var/www
     323}}}
     324
     325Add the following snippet to Apache configuration, changing paths to match your deployment. The snippet must be placed ''before'' the `ScriptAlias` or `WSGIScriptAlias` directive, because those directives map all requests to the Trac application:
     326{{{#!apache
     327Alias /trac/chrome /path/to/trac/htdocs
    327328
    328329<Directory "/path/to/www/trac/htdocs">
    329   Order allow,deny
    330   Allow from all
     330  # For Apache 2.2
     331  <IfModule !mod_authz_core.c>
     332    Order allow,deny
     333    Allow from all
     334  </IfModule>
     335  # For Apache 2.4
     336  <IfModule mod_authz_core.c>
     337    Require all granted
     338  </IfModule>
    331339</Directory>
    332340}}}
    333341
    334 If using mod_python, you might want to add this too, otherwise the alias will be ignored:
     342If using mod_python, add this too, otherwise the alias will be ignored:
    335343{{{#!apache
    336 <Location "/trac/chrome/common/">
     344<Location "/trac/chrome/common">
    337345  SetHandler None
    338346</Location>
    339347}}}
    340348
    341 Note that we mapped `/trac` part of the URL to the `trac.*cgi` script, and the path `/trac/chrome/common` is the path you have to append to that location to intercept requests to the static resources.
    342 
    343 Similarly, if you have static resources in a project's `htdocs` directory (which is referenced by `/trac/chrome/site` URL in themes), you can configure Apache to serve those resources (again, put this ''before'' the `ScriptAlias` or `WSGIScriptAlias` for the .*cgi scripts, and adjust names and locations to match your installation):
     349Alternatively, if you wish to serve static resources directly from your project's `htdocs` directory rather than the location to which the files are extracted with the `deploy` command, you can configure Apache to serve those resources. Again, put this ''before'' the `ScriptAlias` or `WSGIScriptAlias` for the .*cgi scripts, and adjust names and locations to match your installation:
    344350{{{#!apache
    345351Alias /trac/chrome/site /path/to/projectenv/htdocs
    346352
    347353<Directory "/path/to/projectenv/htdocs">
    348   Order allow,deny
    349   Allow from all
     354  # For Apache 2.2
     355  <IfModule !mod_authz_core.c>
     356    Order allow,deny
     357    Allow from all
     358  </IfModule>
     359  # For Apache 2.4
     360  <IfModule mod_authz_core.c>
     361    Require all granted
     362  </IfModule>
    350363</Directory>
    351364}}}
    352365
    353 Alternatively to aliasing `/trac/chrome/common`, you can tell Trac to generate direct links for those static resources (and only those), using the [[TracIni#trac-section| [trac] htdocs_location]] configuration setting:
     366Another alternative to aliasing `/trac/chrome/common` is having Trac generate direct links for those static resources (and only those), using the [TracIni#trac-section htdocs_location] configuration setting:
    354367{{{#!ini
    355368[trac]
     
    357370}}}
    358371
    359 Note that this makes it easy to have a dedicated domain serve those static resources, preferentially [http://code.google.com/speed/page-speed/docs/request.html#ServeFromCookielessDomain cookie-less].
     372Note that this makes it easy to have a dedicated domain serve those static resources, preferentially cookie-less.
    360373
    361374Of course, you still need to make the Trac `htdocs/common` directory available through the web server at the specified URL, for example by copying (or linking) the directory into the document root of the web server:

    366 ==== Setting up the Plugin Cache
     379==== Setting up the Plugin Cache #egg-cache
    367380
    368381Some 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.
     382
     383If 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.

    393 
    394 === Enable version control components
    395 
    396 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.
    397 
    398 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:
    399 
    400 {{{#!ini
    401 [components]
    402 tracopt.versioncontrol.svn.* = enabled
    403 }}}
    404 
    405 {{{#!ini
    406 [components]
    407 tracopt.versioncontrol.git.* = enabled
    408 }}}
    409 
    410 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].
    411 
    412 === Using Trac
     404This user will have an //Admin// navigation item that directs to pages for administering your Trac project.
