    45Trac 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.
    56
    6 Since version 0.12, Trac can also be localized, and there's probably a translation available for your language. If you want to be able 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, as usual.

    8 If you're interested in contributing new translations for other languages or enhance the existing translations, then please have a look at [[trac:TracL10N]].

    10 What follows are generic instructions for installing and setting up Trac and its requirements. While you may find instructions for installing Trac on specific systems at [trac:TracInstallPlatforms TracInstallPlatforms] on the main Trac site, please be sure to '''first read through these general instructions''' to get a good understanding of the tasks involved.

     15== Dependencies
     16
    1517=== Mandatory Dependencies
     18
    1619To install Trac, the following software packages must be installed:
    1720
    1821 * [http://www.python.org/ Python], version >= 2.5 and < 3.0
    1922   (note that we dropped the support for Python 2.4 in this release)
    20  * [http://peak.telecommunity.com/DevCenter/setuptools setuptools], version >= 0.6, or better yet, [http://pypi.python.org/pypi/distribute distribute]
    21  * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.6 (unreleased version 0.7dev should work as well)
    22 
    23 You also need a database system and the corresponding python bindings.
    24 The database can be either SQLite, PostgreSQL or MySQL.
     23 * [http://pypi.python.org/pypi/setuptools setuptools], version >= 0.6
     24 * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.6
     25
     26You also need a database system and the corresponding python bindings. The database can be either SQLite, PostgreSQL or MySQL.
    2527
    2628==== For the SQLite database #ForSQLite
    2729
    28 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).
    29 
    30 However, if you'd like, you can download the latest and greatest version of [[trac:Pysqlite]] from
    31 [http://code.google.com/p/pysqlite/downloads/list google code], where you'll find the Windows
    32 installers or the `tar.gz` archive for building from source:
    33 {{{
    34 $ tar xvfz <version>.tar.gz
    35 $ cd <version>
    36 $ python setup.py build_static install
    37 }}}
    38  
    39 This will download the latest SQLite code and build the bindings.
    40 
    41 SQLite 2.x is no longer supported.
    42 
    43 A known bug PySqlite versions 2.5.2-4 prohibits upgrade of trac databases
    44 from 0.11.x to 0.12. Please use versions 2.5.5 and newer or 2.5.1 and
    45 older. See #9434 for more detail.
    46 
    47 See additional information in [trac:PySqlite PySqlite].
     30As 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.
     31
     32Optionally, 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.
    4833
    4934==== For the PostgreSQL database #ForPostgreSQL
     
    5136You need to install the database and its Python bindings:
    5237 * [http://www.postgresql.org/ PostgreSQL], version 8.0 or later
    53  * [http://pypi.python.org/pypi/psycopg2 psycopg2]
     38 * [http://pypi.python.org/pypi/psycopg2 psycopg2], version 2.0 or later
    5439
    5540See [trac:DatabaseBackend#Postgresql DatabaseBackend] for details.
    5641
    57 
    5842==== For the MySQL database #ForMySQL
    5943
    60 Trac can now work quite well with MySQL, provided you follow the guidelines.
    61 
    62  * [http://mysql.com/ MySQL], version 5.0 or later
     44Trac works well with MySQL, provided you follow the guidelines:
     45
     46 * [http://mysql.com/ MySQL] or [http://mariadb.org/ MariaDB], version 5.0 or later
    6347 * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.2 or later
    6448
    65 It is '''very''' important to read carefully the [trac:MySqlDb] page before creating the database.
     49Given the caveats and known issues surrounding MySQL, read the [trac:MySqlDb] page before creating the database.
    6650
    6751=== Optional Dependencies
    6852
    69 ==== Version Control System ====
    70 
    71 ===== Subversion =====
    72  * [http://subversion.apache.org/ Subversion], 1.5.x or 1.6.x and the '''''corresponding''''' Python bindings. Older versions starting from 1.0, like 1.2.4, 1.3.2 or 1.4.2, etc. should still work. For troubleshooting information, check the [trac:TracSubversion#Troubleshooting TracSubversion] page.
    73 
    74 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. TracSubversion points you to [http://alagazam.net Algazam], which works for me under Python 2.6.)
     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.
     57
     58There 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.)
    7559
    7660Note that Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], neither does it work yet with the newer `ctype`-style bindings.
    7761
    78 
    79 '''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently [trac:ticket:493 not supported].
    80 
    81 
    82 ===== Others =====
    83 
    84 Support for other version control systems is provided via third-parties. See [trac:PluginList] and [trac:VersionControlSystem].
    85 
    86 ==== Web Server ====
    87 A web server is optional because Trac is shipped with a server included, see the [#RunningtheStandaloneServer Running the Standalone Server ] section below.
    88 
    89 Alternatively you configure Trac to run in any of the following environments.
     62'''Note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently [trac:ticket:493 not supported].

    116 '''Attention''': The various available versions of these dependencies are not necessarily interchangable, so please pay attention to the version numbers above. If you are having trouble getting Trac to work please double-check all the dependencies before asking for help on the [trac:MailingList] or [trac:IrcChannel].
    117 
    118 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'' (there are even some pages that are still talking about Trac 0.8!).

     109
     110== Installing Trac
     111
     112The [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.
     113
     114It 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.
     115
    122116=== Using `easy_install`
    123 One way to install Trac is using [http://pypi.python.org/pypi/setuptools setuptools].
    124 With setuptools you can install Trac from the subversion repository;
    125 
    126 A few examples:
    127 
    128  - install Trac 1.0:
    129    {{{
    130    easy_install Trac==1.0
    131    }}}
    132    (NOT YET ENABLED)
    133  - install latest development version 1.0dev:
    134    {{{
    135    easy_install Trac==dev
    136    }}}
     117
     118Trac can be installed from [https://pypi.python.org/pypi/Trac PyPI] or the Subversion repository using [http://pypi.python.org/pypi/setuptools setuptools].
     119
     120A few command-line examples:
     121
     122 - Install the latest stable version of Trac:
     123 {{{#!sh
     124$ easy_install Trac
     125}}}
     126 - Install latest development version:
     127 {{{#!sh
     128$ easy_install http://download.edgewall.org/trac/Trac-latest-dev.tar.gz
     129}}}
    137130   Note that in this case you won't have the possibility to run a localized version of Trac;
    138    either use a released version or install from source
     131   either use a released version or install from source.
     132
     133More information can be found on the [trac:wiki:setuptools setuptools] page.
     134
     135{{{#!div style="border: 1pt dotted; margin: 1em"
     136**Setuptools Warning:** If the version of your setuptools is in the range 5.4 through 5.6, the environment variable `PKG_RESOURCES_CACHE_ZIP_MANIFESTS` must be set in order to avoid significant performance degradation. More information may be found in [#DeployingTrac Deploying Trac].
     137}}}
    139138
    140139=== Using `pip`
    141 'pip' is an easy_install replacement that is very useful to quickly install python packages.
    142 To get a trac installation up and running in less than 5 minutes:
    143 
    144 Assuming you want to have your entire pip installation in `/opt/user/trac`

     142To get a Trac installation up and running in less than 5 minutes:
     143
     144Assuming you want to have your entire pip installation in `/opt/user/trac`:
    145145
    146146 -
    147 {{{
    148 pip -E /opt/user/trac install trac psycopg2
    149 }}}
    150 or
     147 {{{#!sh
     148$ pip install trac psycopg2
     149}}}
     150or:
    151151 -
    152 {{{
    153 pip -E /opt/user/trac install trac mysql-python
    154 }}}
    155 
    156 Make sure your OS specific headers are available for pip to automatically build PostgreSQL (libpq-dev) or MySQL (libmysqlclient-dev) bindings.
    157 
    158 pip will automatically resolve all dependencies (like Genshi, pygments, etc.) and download the latest packages on pypi.python.org and create a self contained installation in `/opt/user/trac`.
    159 
    160 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)
    161 
    162 Additionally, you can install several trac plugins (listed [http://pypi.python.org/pypi?:action=search&term=trac&submit=search here]) through pip.
    163 
    164 
     152 {{{#!sh
     153$ pip install trac mysql-python
     154}}}

    165163
    166164=== From source
    167 Of course, using the python-typical setup at the top of the source directory also works.
    168 
    169 You can obtain the source for a .tar.gz or .zip file corresponding to a release (e.g. Trac-1.0.tar.gz), or you can get the source directly from the repository (see Trac:SubversionRepository for details).

    174171
    175 ''You'll need root permissions or equivalent for this step.''
    176 
    177 This will byte-compile the python source code and install it as an .egg file or folder in the `site-packages` directory
    178 of your Python installation. The .egg will also contain all other resources needed by standard Trac, such as htdocs and templates.
    179 
    180 The script will also install the [wiki:TracAdmin trac-admin] command-line tool, used to create and maintain [wiki:TracEnvironment project environments], as well as the [wiki:TracStandalone tracd] standalone server.
    181 
    182 If you install from source and want to make Trac available in other languages, make sure  Babel is installed. Only then, perform the `install` (or simply redo the `install` once again afterwards if you realize Babel was not yet installed):

     182Alternatively, 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`).
     183
     184=== Using installer
     185
     186On 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.
     187
     188=== Using package manager
     189
     190Trac may be available in the package repository for your platform. Note however, that the version provided by the package manager may not be the latest release.
     191
     192=== Advanced `easy_install` Options
    189193
    190194To install Trac to a custom location, or find out about other advanced installation options, run:

    210 == Creating a Project Environment ==
    211 
    212 A [TracEnvironment Trac environment] is the backend storage 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 various other files and directories.

    214 A new environment is created using [wiki:TracAdmin trac-admin]:

     218
     219A new environment is created using [TracAdmin trac-admin]:
     220{{{#!sh
    216221$ trac-admin /path/to/myproject initenv
    217222}}}
     
    220225
    221226Using the default database connection string in particular will always work as long as you have SQLite installed.
    222 For the other [DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
    223 
    224 Since 0.12, Trac doesn't ask for a [TracEnvironment#SourceCodeRepository source code repository] anymore when creating an environment. Repositories can be [TracRepositoryAdmin added] afterward, or the version control support can be disabled completely if you don't need it.
     227For the other [trac:DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
     228
     229Since 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.
    225230
    226231Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file.

     234**Filesystem Warning:** When selecting the location of your environment, make sure that the filesystem on which the environment directory resides supports sub-second timestamps (i.e. **not** `ext2` or `ext3` on Linux, or HFS+ on OSX), as the modification time of the `conf/trac.ini` file will be monitored to decide whether an environment restart is needed or not. A too coarse-grained timestamp resolution may result in inconsistencies in Trac < 1.0.2. The best advice is to opt for a platform with sub-second timestamp resolution, regardless of the Trac version.
     235}}}
     236
    228237Finally, 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:
    229 {{{

    239249
    240 === Running the Standalone Server ===
    241 
    242 After having created a Trac environment, you can easily try the web interface by running the standalone server [wiki:TracStandalone tracd]:
    243 {{{
     250{{{#!div style="border: 1pt dotted; margin: 1em"
     251**Setuptools Warning:** If the version of your setuptools is in the range 5.4 through 5.6, the environment variable `PKG_RESOURCES_CACHE_ZIP_MANIFESTS` must be set in order to avoid significant performance degradation.
     252
     253If running `tracd`, the environment variable can be set system-wide or for just the user that runs the `tracd` process. There are several ways to accomplish this in addition to what is discussed here, and depending on the distribution of your OS.
     254
     255To 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`.
     256{{{#!sh
     257export PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1
     258}}}
     259
     260Alternatively, the variable can be set in the shell before executing `tracd`:
     261{{{#!sh
     262$ PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1 tracd --port 8000 /path/to/myproject
     263}}}
     264
     265If running the Apache web server, !Ubuntu/Debian users should add the `export` statement to `/etc/apache2/envvars`. !RedHat/CentOS/Fedora should can add the `export` statement to `/etc/sysconfig/httpd`.
     266}}}
     267
     268=== Running the Standalone Server
     269
     270After having created a Trac environment, you can easily try the web interface by running the standalone server [TracStandalone tracd]:
     271{{{#!sh
    244272$ tracd --port 8000 /path/to/myproject
    245273}}}
    246274
    247275Then, fire up a browser and visit `http://localhost:8000/`. You should get a simple listing of all environments that `tracd` knows about. Follow the link to the environment you just created, and you should see Trac in action. If you only plan on managing a single project with Trac you can have the standalone server skip the environment list by starting it like this:
    248 {{{
     276{{{#!sh
    249277$ tracd -s --port 8000 /path/to/myproject

    252 === Running Trac on a Web Server ===
     280=== Running Trac on a Web Server
    253281
    254282Trac provides various options for connecting to a "real" web server:
    255  - [wiki:TracFastCgi FastCGI]
    256  - [wiki:TracModWSGI mod_wsgi]
    257  - //[wiki:TracModPython mod_python] (no longer recommended, as mod_python is not actively maintained anymore)//
    258  - //[wiki:TracCgi CGI] (should not be used, as the performance is far from optimal)//
     283 - [TracFastCgi FastCGI]
     284 - [wiki:TracModWSGI Apache with mod_wsgi]
     285 - [TracModPython Apache with mod_python]
     286 - //[TracCgi CGI]: should not be used, as it degrades performance//
    259287
    260288Trac 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.
    261289
    262 ==== Generating the Trac cgi-bin directory ==== #cgi-bin
    263 
    264 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 [wiki:TracAdmin trac-admin].
    265 
    266 There is, however, a bit of a chicken-and-egg problem. The [wiki: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:
    267 {{{
    268 mkdir -p /usr/share/trac/projects/my-project
    269 trac-admin /usr/share/trac/projects/my-project initenv
    270 trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy
    271 mv /tmp/deploy/* /usr/share/trac
    272 }}}
    273 
    274 
    275 ==== Mapping Static Resources ====
    276 
    277 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''' and will cause abysmal performance).
    278 
    279 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.
    280 
    281 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.
    282 
    283 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:
     290==== Generating the Trac cgi-bin directory #cgi-bin
     291
     292In 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].
     293
     294There 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:
     295{{{#!sh
     296$ mkdir -p /usr/share/trac/projects/my-project
     297$ trac-admin /usr/share/trac/projects/my-project initenv
     298$ trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy
     299$ mv /tmp/deploy/* /usr/share/trac
     300}}}
     301
     302Don't forget to check that the web server has the execution right on scripts in the `/usr/share/trac/cgi-bin` directory.
     303
     304==== Mapping Static Resources
     305
     306Without 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.
     307
     308Web 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.
     309
     310There 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.
     311
     312A 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.
     313
     314The resources are extracted using the [TracAdmin trac-admin]` <environment> deploy` command:
    284315[[TracAdminHelp(deploy)]]
    285316
    286 The target `<directory>` will then contain an `htdocs` directory with:
    287  - `site/` - a copy of the environment's directory `htdocs/`
    288  - `common/` - the static resources of Trac itself
    289  - `<plugins>/` - one directory for each resource directory managed by the plugins enabled for this environment
    290 
    291 ===== Example: Apache and `ScriptAlias` ===== #ScriptAlias-example
    292 
    293 Assuming the deployment has been done this way:
    294 {{{
    295 $ trac-admin /var/trac/env deploy /path/to/trac/htdocs/common
    296 }}}
    297 
    298 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:
    299 {{{
     317The target `<directory>` will contain an `htdocs` directory with:
     318 - `common/` - the static resources of Trac
     319 - `site/` - a copy of the environment's `htdocs/` directory
     320 - `shared` - the static resources shared by multiple Trac environments, with a location defined by the `[inherit]` `htdocs_dir` option
     321 - `<plugin>/` - one directory for each resource directory provided by the plugins enabled for this environment
     322
     323The 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:
     324{{{#!apache
    300325Alias /trac/chrome/common /path/to/trac/htdocs/common
    301326Alias /trac/chrome/site /path/to/trac/htdocs/site
     327Alias /trac/chrome/shared /path/to/trac/htdocs/shared
     328Alias /trac/chrome/<plugin> /path/to/trac/htdocs/<plugin>
     329}}}
     330
     331===== Example: Apache and `ScriptAlias` #ScriptAlias-example
     332
     333Assuming the deployment has been done this way:
     334{{{#!sh
     335$ trac-admin /var/trac/env deploy /path/to/shared/trac
     336}}}
     337
     338Add 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:
     339{{{#!apache
     340Alias /trac/chrome /path/to/trac/htdocs
    302341
    303342<Directory "/path/to/www/trac/htdocs">
    304   Order allow,deny
    305   Allow from all
     343  # For Apache 2.2
     344  <IfModule !mod_authz_core.c>
     345    Order allow,deny
     346    Allow from all
     347  </IfModule>
     348  # For Apache 2.4
     349  <IfModule mod_authz_core.c>
     350    Require all granted
     351  </IfModule>
    306352</Directory>
    307353}}}
    308354
    309 If using mod_python, you might want to add this too (otherwise, the alias will be ignored):
    310 {{{
    311 <Location "/trac/chrome/common/">
     355If using mod_python, add this too, otherwise the alias will be ignored:
     356{{{#!apache
     357<Location "/trac/chrome/common">
    312358  SetHandler None
    313359</Location>
    314360}}}
    315361
    316 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.
    317 
    318 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):
    319 {{{
     362Alternatively, 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:
     363{{{#!apache
    320364Alias /trac/chrome/site /path/to/projectenv/htdocs
    321365
    322366<Directory "/path/to/projectenv/htdocs">
    323   Order allow,deny

     374    Require all granted
     375  </IfModule>
    325376</Directory>
    326377}}}
    327378
    328 Alternatively to aliasing `/trac/chrome/common`, you can tell Trac to generate direct links for those static resources (and only those), using the [[wiki:TracIni#trac-section| [trac] htdocs_location]] configuration setting:
    329 {{{
     379Another 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:
     380{{{#!ini
    330381[trac]
    331382htdocs_location = http://static.example.org/trac-common/
    332383}}}
    333 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]).
     384
     385Note that this makes it easy to have a dedicated domain serve those static resources, preferentially cookie-less.
    334386
    335387Of 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:
    336 {{{
     388{{{#!sh
    337389$ ln -s /path/to/trac/htdocs/common /var/www/static.example.org/trac-common

    339391
    340 
    341 ==== Setting up the Plugin Cache ====
    342 
    343 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.
    344 
    345 == Configuring Authentication ==
    346 
    347 Trac uses HTTP authentication. You'll need to configure your webserver to request authentication when the `.../login` URL is hit (the virtual path of the "login" button). Trac will automatically pick the REMOTE_USER variable up after you provide your credentials. Therefore, all user management goes through your web server configuration. Please consult the documentation of your web server for more info.

    365 === Automatic reference to the SVN changesets in Trac tickets ===
    366 
    367 You can configure SVN to automatically add a reference to the changeset into the ticket comments, whenever changes are committed to the repository. The description of the commit needs to contain one of the following formulas:
    368  * '''`Refs #123`''' - to reference this changeset in `#123` ticket
    369  * '''`Fixes #123`''' - to reference this changeset and close `#123` ticket with the default status ''fixed''
    370 
    371 This functionality requires a post-commit hook to be installed as described in [wiki:TracRepositoryAdmin#ExplicitSync TracRepositoryAdmin], and enabling the optional commit updater components by adding the following line to the `[components]` section of your [wiki:TracIni#components-section trac.ini], or enabling the components in the "Plugins" admin panel.
    372 {{{
    373 tracopt.ticket.commit_updater.* = enabled

    377 === Using Trac ===
     420=== Enable version control components
     421
     422Support 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.
     423
     424The 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:
     425
     426{{{#!ini
     427[components]
     428tracopt.versioncontrol.svn.* = enabled

     431{{{#!ini
     432[components]
     433tracopt.versioncontrol.git.* = enabled
     434}}}
     435
     436After 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].
