    4 Trac is a lightweight project management tool that is implemented as a web-based application. Trac is written in the Python programming language and can use [http://sqlite.org/ SQLite] or [http://www.postgresql.org/ PostgreSQL] as  database. For HTML rendering, Trac uses the [http://www.clearsilver.net/ Clearsilver] templating system. 
    5  
    6 What follows are generic instructions for installing and setting up Trac and its requirements. While you can find instructions for installing Trac on specific systems at [http://projects.edgewall.com/trac/wiki/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.

    8 == Requirements == 
    9  
     4Trac 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. 
     5 
     6Since 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. 
     7 
     8If you're interested in contributing new translations for other languages or enhance the existing translations, then please have a look at [[trac:TracL10N]].

     10What 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.

     14== Dependencies == 
     15=== Mandatory Dependencies 
    1016To install Trac, the following software packages must be installed: 
    1117 
    12  * [http://www.python.org/ Python], version >= 2.3. 
    13    * Python 2.4 is not supported on Windows since there are no Subversion bindings available for it. 
    14    * For RPM-based systems you might also need the `python-devel` and `python-xml` packages. 
    15  * [http://subversion.tigris.org/ Subversion], version >= 1.0. (>= 1.1 recommended) and corresponding [http://svnbook.red-bean.com/svnbook-1.1/ch08s02.html#svn-ch-8-sect-2.3 Python bindings] 
    16    * Trac uses the [http://www.swig.org/ SWIG] bindings included in the Subversion distribution, '''not''' [http://pysvn.tigris.org/ PySVN] (which is sometimes confused with the standard SWIG bindings). 
    17    * If Subversion was already installed without the SWIG bindings, you'll need to re-`configure` Subversion and `make swig-py`, `make install-swig-py`. 
    18  * [http://www.clearsilver.net/ ClearSilver], version >= 0.9.3 
    19    * With python-bindings (`./configure --with-python=/usr/bin/python`) 
    20  
    21 === For SQLite === 
    22  
    23  * [http://www.sqlite.org/ SQLite], version 2.8.x or 3.x 
    24  * [http://pysqlite.org/ PySQLite] 
    25    * version 1.0.x (for SQLite 2.8.x) 
    26    * version 1.1.x or 2.x (for SQLite 3.x) 
    27  
    28 === For PostgreSQL === 
    29  
    30  * [http://www.postgresql.org/ PostgreSQL] 
    31  * [http://initd.org/projects/psycopg1 psycopg1], [http://initd.org/projects/psycopg2 psycopg2], or [http://pypgsql.sourceforge.net/ pyPgSQL] 
    32  
    33 === Optional Requirements === 
    34  
    35  * A CGI-capable web server (see TracCgi), or 
    36  * a [http://www.fastcgi.com/ FastCGI]-capable web server (see TracFastCgi), or 
    37  * [http://httpd.apache.org/ Apache] with [http://www.modpython.org/ mod_python 3.1.3+] (see TracModPython) 
    38  * [http://peak.telecommunity.com/DevCenter/setuptools setuptools], version >= 0.5a13 for using plugins (see TracPlugins) 
    39  * [http://docutils.sourceforge.net/ docutils], version >= 0.3.3 for WikiRestructuredText. 
    40  * [http://silvercity.sourceforge.net/ SilverCity] and/or [http://www.gnu.org/software/enscript/enscript.html Enscript] for [wiki:TracSyntaxColoring syntax highlighting]. 
    41  
    42 '''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 [http://projects.edgewall.com/trac/wiki/MailingList MailingList] or [http://projects.edgewall.com/trac/wiki/IrcChannel IrcChannel]. 
    43  
    44 Please refer to the documentation of these packages to find out how they are best installed. In addition, most of the [http://projects.edgewall.com/trac/wiki/TracInstallPlatforms platform-specific instructions] also describe the installation of the dependencies. 
     18 * [http://www.python.org/ Python], version >= 2.5 and < 3.0 
     19   (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 
     23You also need a database system and the corresponding python bindings. 
     24The database can be either SQLite, PostgreSQL or MySQL. 
     25 
     26==== For the SQLite database #ForSQLite 
     27 
     28As 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 
     30However, 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 
     32installers 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  
     39This will download the latest SQLite code and build the bindings.  
     40 
     41SQLite 2.x is no longer supported. 
     42 
     43A known bug PySqlite versions 2.5.2-4 prohibits upgrade of trac databases 
     44from 0.11.x to 0.12. Please use versions 2.5.5 and newer or 2.5.1 and 
     45older. See #9434 for more detail. 
     46 
     47See additional information in [trac:PySqlite PySqlite]. 
     48 
     49==== For the PostgreSQL database #ForPostgreSQL 
     50 
     51You need to install the database and its Python bindings: 
     52 * [http://www.postgresql.org/ PostgreSQL], version 8.0 or later 
     53 * [http://pypi.python.org/pypi/psycopg2 psycopg2] 
     54 
     55See [trac:DatabaseBackend#Postgresql DatabaseBackend] for details. 
     56 
     57 
     58==== For the MySQL database #ForMySQL 
     59 
     60Trac can now work quite well with MySQL, provided you follow the guidelines. 
     61 
     62 * [http://mysql.com/ MySQL], version 5.0 or later 
     63 * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.2 or later 
     64 
     65It is '''very''' important to read carefully the  [trac:MySqlDb] page before creating the database. 
     66 
     67=== Optional Dependencies 
     68 
     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 
     74There 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.) 
     75 
     76Note that Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], neither does it work yet with the newer `ctype`-style bindings.  
     77 
     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 
     84Support for other version control systems is provided via third-parties. See [trac:PluginList] and [trac:VersionControlSystem]. 
     85 
     86==== Web Server ==== 
     87A web server is optional because Trac is shipped with a server included, see the [#RunningtheStandaloneServer Running the Standalone Server ] section below. 
     88 
     89Alternatively you configure Trac to run in any of the following environments. 
     90 * [http://httpd.apache.org/ Apache] with  
     91   - [http://code.google.com/p/modwsgi/ mod_wsgi], see [wiki:TracModWSGI] and  
     92     http://code.google.com/p/modwsgi/wiki/IntegrationWithTrac 
     93   - [http://modpython.org/ mod_python 3.3.1], deprecated: see TracModPython) 
     94 * a [http://www.fastcgi.com/ FastCGI]-capable web server (see TracFastCgi) 
     95 * an [http://tomcat.apache.org/connectors-doc/ajp/ajpv13a.html AJP]-capable web 
     96   server (see [trac:TracOnWindowsIisAjp TracOnWindowsIisAjp]) 
     97 * a CGI-capable web server (see TracCgi), '''but usage of Trac as a cgi script  
     98   is highly discouraged''', better use one of the previous options.  
     99    
     100 
     101==== Other Python Packages ==== 
     102 
     103 * [http://babel.edgewall.org Babel], version >= 0.9.5,  
     104   needed for localization support (unreleased version 1.0dev should work as well) 
     105 * [http://docutils.sourceforge.net/ docutils], version >= 0.3.9  
     106   for WikiRestructuredText. 
     107 * [http://pygments.pocoo.org Pygments] for  
     108   [wiki:TracSyntaxColoring syntax highlighting]. 
     109   [http://silvercity.sourceforge.net/ SilverCity] and/or  
     110   [http://gnu.org/software/enscript/enscript.html Enscript] may still be used 
     111   but are deprecated and you really should be using Pygments. 
     112 * [http://pytz.sf.net pytz] to get a complete list of time zones, 
     113   otherwise Trac will fall back on a shorter list from  
     114   an internal time zone implementation. 
     115 
     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 
     118Please 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!). 
     119 
    45120 
    46121== Installing Trac == 
    47  
    48 Like most Python programs, the Trac Python package is installed by running the following command at the top of the source directory: 
     122=== Using `easy_install` 
     123One way to install Trac is using [http://pypi.python.org/pypi/setuptools setuptools]. 
     124With setuptools you can install Trac from the subversion repository;  
     125 
     126A 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   }}} 
     137   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  
     139 
     140=== Using `pip` 
     141'pip' is an easy_install replacement that is very useful to quickly install python packages. 
     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` 
     145 
     146 -  
     147{{{ 
     148pip -E /opt/user/trac install trac psycopg2  
     149}}} 
     150or 
     151 -  
     152{{{ 
     153pip -E /opt/user/trac install trac mysql-python  
     154}}} 
     155 
     156Make sure your OS specific headers are available for pip to automatically build PostgreSQL (libpq-dev) or MySQL (libmysqlclient-dev) bindings. 
     157 
     158pip 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 
     160All 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 
     162Additionally, you can install several trac plugins (listed [http://pypi.python.org/pypi?:action=search&term=trac&submit=search here]) through pip. 
     163 
     164 
     165 
     166=== From source 
     167Of course, using the python-typical setup at the top of the source directory also works. 
     168 
     169You 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). 
     170 
    49171{{{ 
    50172$ python ./setup.py install 
    51173}}} 
    52174 
    53 ''Note: you'll need root permissions or equivalent for this step.'' 
    54  
    55 This will byte-compile the python source code and install it in the `site-packages` directory 
    56 of your Python installation. The directories `cgi-bin`, `templates`, `htdocs`, `wiki-default` and `wiki-macros` are all copied to `$prefix/share/trac/.` 
     175''You'll need root permissions or equivalent for this step.'' 
     176 
     177This will byte-compile the python source code and install it as an .egg file or folder in the `site-packages` directory 
     178of your Python installation. The .egg will also contain all other resources needed by standard Trac, such as htdocs and templates. 
    57179 
    58180The script will also install the [wiki:TracAdmin trac-admin] command-line tool, used to create and maintain [wiki:TracEnvironment project environments], as well as the [wiki:TracStandalone tracd] standalone server. 
    59181 
    60 === Advanced Users === 
     182If you install from source and want to make Trac available in other languages, make sure  Babel is installed. Only then, perform the `install` (or simply redo the `install` once again afterwards if you realize Babel was not yet installed): 
     183{{{ 
     184$ python ./setup.py install 
     185}}} 
     186Alternatively, you can do a `bdist_egg` and copy the .egg from dist/ to the place of your choice, or you can create a Windows installer (`bdist_wininst`). 
     187 
     188=== Advanced Options === 
    61189 
    62190To install Trac to a custom location, or find out about other advanced installation options, run: 
    63191{{{ 
    64 $ python ./setup.py --help 
    65 }}} 
     192easy_install --help 
     193}}} 
     194 
     195Also see [http://docs.python.org/inst/inst.html Installing Python Modules] for detailed information. 
    66196 
    67197Specifically, you might be interested in: 
    68198{{{ 
    69 $ python ./setup.py install --prefix=/path/you/want 
    70 }}} 
     199easy_install --prefix=/path/to/installdir 
     200}}} 
     201or, if installing Trac to a Mac OS X system: 
     202{{{ 
     203easy_install --prefix=/usr/local --install-dir=/Library/Python/2.5/site-packages 
     204}}} 
     205Note: If installing on Mac OS X 10.6 running {{{ easy_install http://svn.edgewall.org/repos/trac/trunk }}} will install into {{{ /usr/local }}} and {{{ /Library/Python/2.6/site-packages }}} by default 
     206 
     207The above will place your `tracd` and `trac-admin` commands into `/usr/local/bin` and will install the Trac libraries and dependencies into `/Library/Python/2.5/site-packages`, which is Apple's preferred location for third-party Python application installations. 
    71208 
    72209 
    73210== Creating a Project Environment == 
    74211 
    75 A [wiki: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 configuration file and various other files and directories. 
     212A [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. 
    76213 
    77214A new environment is created using [wiki:TracAdmin trac-admin]: 
    78215{{{ 
    79 $ trac-admin /path/to/trac_project_env initenv 
    80 }}} 
    81  
    82 [wiki:TracAdmin trac-admin] will prompt you for the information it needs to create the environment, such as the name of the project, the path to an existing subversion repository, the [wiki:TracEnvironment#DatabaseConnectionStrings database connection string], and so on. If you're not sure what to specify for one of these options, just leave it blank to use the default value. The database connection string in particular will always work as long as you have SQLite installed. The only option where the default value is likely to not work is the path to the Subversion repository, so make sure that one's correct. 
    83  
    84 Also note that the values you specify here can be changed later by directly editing the [wiki:TracIni] configuration file. 
    85  
    86 ''Note: The user account under which the web server runs will require write permissions to the environment 
    87 directory and all the files inside.'' 
    88  
    89  
    90 == Running the Standalone Server == 
     216$ trac-admin /path/to/myproject initenv 
     217}}} 
     218 
     219[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.  
     220 
     221Using the default database connection string in particular will always work as long as you have SQLite installed. 
     222For the other [DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point. 
     223 
     224Since 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. 
     225 
     226Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file. 
     227 
     228Finally, 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{{{ 
     230# chown -R apache.apache /path/to/myproject 
     231}}} 
     232 
     233{{{#!div class=important

     237 
     238== Deploying Trac 
     239 
     240=== Running the Standalone Server === 
    91241 
    92242After having created a Trac environment, you can easily try the web interface by running the standalone server [wiki:TracStandalone tracd]: 
    93243{{{ 
    94 $ tracd --port 8000 /path/to/projectenv 
    95 }}} 
    96  
    97 Then, 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. 
    98  
    99  
    100 == Running Trac on a Web Server == 
    101  
    102 Trac provides three options for connecting to a “real” web server: [wiki:TracCgi CGI], [wiki:TracFastCgi FastCGI] and [wiki:TracModPython mod_python]. For decent performance, it is recommended that you use either FastCGI or mod_python. 
     244$ tracd --port 8000 /path/to/myproject 
     245}}} 
     246 
     247Then, 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{{{ 
     249$ tracd -s --port 8000 /path/to/myproject 
     250}}} 
     251 
     252=== Running Trac on a Web Server ===

     254Trac 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)// 
     259 
     260Trac 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. 
     261 
     262==== Generating the Trac cgi-bin directory ==== #cgi-bin 
     263 
     264In 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 
     266There 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{{{ 
     268mkdir -p /usr/share/trac/projects/my-project 
     269trac-admin /usr/share/trac/projects/my-project initenv 
     270trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy 
     271mv /tmp/deploy/* /usr/share/trac 
     272}}} 
     273 
     274 
     275==== Mapping Static Resources ==== 
     276 
     277Out 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 
     279Web 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 
     281There 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 
     283Note 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: 
     284[[TracAdminHelp(deploy)]] 
     285 
     286The 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 
     293Assuming the deployment has been done this way: 
     294{{{ 
     295$ trac-admin /var/trac/env deploy /path/to/trac/htdocs/common 
     296}}} 
     297 
     298Add 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{{{ 
     300Alias /trac/chrome/common /path/to/trac/htdocs/common 
     301Alias /trac/chrome/site /path/to/trac/htdocs/site 
     302 
     303<Directory "/path/to/www/trac/htdocs"> 
     304  Order allow,deny 
     305  Allow from all 
     306</Directory> 
     307}}} 
     308 
     309If using mod_python, you might want to add this too (otherwise, the alias will be ignored): 
     310{{{ 
     311<Location "/trac/chrome/common/"> 
     312  SetHandler None 
     313</Location> 
     314}}} 
     315 
     316Note 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 
     318Similarly, 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{{{ 
     320Alias /trac/chrome/site /path/to/projectenv/htdocs 
     321 
     322<Directory "/path/to/projectenv/htdocs"> 
     323  Order allow,deny 
     324  Allow from all 
     325</Directory> 
     326}}} 
     327 
     328Alternatively 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{{{ 
     330[trac] 
     331htdocs_location = http://static.example.org/trac-common/ 
     332}}} 
     333Note 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]). 
     334 
     335Of 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{{{ 
     337$ ln -s /path/to/trac/htdocs/common /var/www/static.example.org/trac-common 
     338}}} 
     339 
     340 
     341==== Setting up the Plugin Cache ==== 
     342 
     343Some 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.

    104345== Configuring Authentication == 
    105346 
    106 The process of adding, removing, and configuring user accounts for authentication depends on the specific way you run Trac.  To learn about how to accomplish these tasks, please visit one of the following pages: 
    107  
    108  * TracStandalone if you use the standalone server, `tracd`. 
    109  * TracCgi if you use the CGI or FastCGI methods. 
    110  * TracModPython if you use the mod_python method. 
    111  
    112 == Using Trac == 
    113  
    114 Once you have your Trac site up and running, you should be able to browse your subversion repository, create tickets, view the timeline, etc. 
    115  
    116 Keep in mind that anonymous (not logged in) users can by default access most but not all of the features. You will need to configure authentication and grant additional [wiki:TracPermissions permissions] to authenticated users to see the full set of features. 
    117  
    118 ''Enjoy!'' 
    119  
    120 [http://projects.edgewall.com/trac/wiki/TracTeam The Trac Team] 
     347Trac 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. 
     348 
     349The process of adding, removing, and configuring user accounts for authentication depends on the specific way you run Trac.  
     350 
     351Please refer to one of the following sections: 
     352 * TracStandalone#UsingAuthentication if you use the standalone server, `tracd`. 
     353 * [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`. 
     354 * TracFastCgi if you're using another web server with FCGI support (Cherokee, Lighttpd, !LiteSpeed, nginx) 
     355 
     356== Granting admin rights to the admin user 
     357Grant admin rights to user admin: 
     358{{{ 
     359$ trac-admin /path/to/myproject permission add admin TRAC_ADMIN 
     360}}} 
     361This user will have an "Admin" entry menu that will allow you to admin your trac project. 
     362 
     363== Finishing the install 
     364 
     365=== Automatic reference to the SVN changesets in Trac tickets === 
     366 
     367You 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 
     371This 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{{{ 
     373tracopt.ticket.commit_updater.* = enabled 
     374}}} 
     375For more information, see the documentation of the `CommitTicketUpdater` component in the "Plugins" admin panel. 
     376 
     377=== Using Trac === 
     378 
     379Once 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. 
     380 
     381Keep in mind that //anonymous// (not logged in) users can by default access only a few of the features, in particular they will have a read-only access to the resources. You will need to configure authentication and grant additional [wiki:TracPermissions permissions] to authenticated users to see the full set of features.
