    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 needs a database (either [http://sqlite.org/ SQLite], [http://www.postgresql.org/ PostgreSQL], or [http://mysql.com/ MySQL] works). 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.

     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 **first** have installed the optional package [#OtherPythonPackages Babel]. Lacking Babel, you will only get the default English version, as usual. If you install Babel later on, you will need to re-install Trac.
     7
     8If you're interested in contributing new translations for other languages or enhance the existing translations, then please have a look at [trac:wiki:TracL10N 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: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.

     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    * For RPM-based systems you might also need the `python-devel` and `python-xml` packages.
    14    * If you want to use Trac with Subversion on Windows, note that there are no precompiled Subversion bindings for Python 2.4, so you probably need Python 2.3.
    15     * 2006-09-20: This seems to be no longer true, see http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91. For subversion 1.4.0 python 2.4 binary bindings are available.
    16  * [http://www.clearsilver.net/ ClearSilver], version >= 0.9.3
    17    * With python-bindings (`./configure --with-python=/usr/bin/python`)
    18  * You also need a database system and the corresponding python drivers for it.
    19    The database can be either SQLite, PostgreSQL or MySQL ''(experimental)''.
    20 
    21 === For SQLite ===
    22 
    23  * [http://www.sqlite.org/ SQLite], version 2.8.x or 3.x (preferred)
    24  * [http://pysqlite.org/ PySQLite], version 1.x (for SQLite 2.x) or version 2.x (for SQLite 3.x). For details see [http://trac.edgewall.org/wiki/PySqlite PySqlite]
    25 
    26 ''Note: Versions of Trac prior to 0.9 do '''not''' work with PySQLite 2.x.''
    27 
    28 ''Note: It appears that PySQLite 2.x is required for Trac 0.9+/SQLite 3.x if you plan to use the 'trac-post-commit-hook.py' script available from the 'contrib' section of the source repository.''
    29 
    30 ''Note: Users of Mac OS X please take care; the Apple-supplied SQLite contains additional code to support file locking on network filesystems like AFP or SMB. This is not presently (3.3.6) in the mainline sources, so if you build your own SQLite from source it will not function correctly on such filesystems - typically it gives the error "{{{database is locked}}}". [http://www.alastairs-place.net/2006/07/sqlite_and_mac/ A patch] is available for version 3.3.6, based on Apple's code, otherwise you're probably best off using the Apple supplied version (presently 3.1.3).''
    31 
    32 === For PostgreSQL ===
    33 
    34  * [http://www.postgresql.org/ PostgreSQL]
    35  * [http://initd.org/projects/psycopg2 psycopg2] or [http://pypgsql.sourceforge.net/ pyPgSQL]
    36 
    37 ''Note: PostgreSQL support requires Trac version 0.9 or later.''
    38 
    39 === For MySQL ===
    40 
    41 '''Warning''': MySQL support is currently experimental. That means it works for some people, but has not been tested extensively yet.
    42 
    43  * [http://mysql.com/ MySQL], version 4.1 or later
    44  * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.1 or later
    45 
    46 ''Note: MySQL support requires Trac version 0.10 or later.''
    47 
    48 === Optional Requirements ===
     18 * [http://www.python.org/ Python], version >= 2.4 and < 3.0
     19   //(note that we dropped the support for Python 2.3 in this release and that this will be the last Trac release supporting Python 2.4)//
     20 * [http://peak.telecommunity.com/DevCenter/setuptools setuptools], version >= 0.6
     21 * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.6 (but < 0.7dev, i.e. don't use Genshi trunk)
     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
     28If you're using Python 2.5 or 2.6, you already have everything you need.
     29
     30If you're using Python 2.4 and need pysqlite, you can download from
     31[http://code.google.com/p/pysqlite/downloads/list google code] the Windows installers or the tar.gz archive for building from source:
     32{{{
     33$ tar xvfz <version>.tar.gz
     34$ cd <version>
     35$ python setup.py build_static install
     36}}}
     37 
     38This will extract the SQLite code and build the bindings.
     39
     40To install SQLite, your system may require the development headers. Without these you will get various GCC related errors when attempting to build:
     41
     42{{{
     43$ apt-get install libsqlite3-dev
     44}}}
     45
     46SQLite 2.x is no longer supported, and neither is !PySqlite 1.1.x.
     47
     48A known bug !PySqlite versions 2.5.2-4 prohibits upgrade of trac databases
     49from 0.11.x to 0.12. Please use versions 2.5.5 and newer or 2.5.1 and
     50older. See [trac:#9434] for more detail.
     51
     52See additional information in [trac:PySqlite].
     53
     54==== For the PostgreSQL database #ForPostgreSQL
     55
     56You need to install the database and its Python bindings:
     57 * [http://www.postgresql.org/ PostgreSQL], version 8.0 or later
     58 * [http://pypi.python.org/pypi/psycopg2 psycopg2]
     59
     60See [trac:DatabaseBackend#Postgresql DatabaseBackend] for details.
     61
     62
     63==== For the MySQL database #ForMySQL
     64
     65Trac can now work quite well with MySQL, provided you follow the guidelines.
     66
     67 * [http://mysql.com/ MySQL], version 5.0 or later
     68 * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.2 or later
     69
     70It is '''very''' important to read carefully the  [trac:MySqlDb] page before creating the database.
     71
     72=== Optional Dependencies
    4973
    5074==== Version Control System ====
    51  * [http://subversion.tigris.org/ Subversion], version >= 1.0. (either 1.2.3 or >= 1.3.1 recommended) and corresponding [http://svnbook.red-bean.com/svnbook-1.1/ch08s02.html#svn-ch-8-sect-2.3 Python bindings]. For troubleshooting, check [http://projects.edgewall.com/trac/wiki/TracSubversion TracSubversion]
    52    * 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).
    53    * If Subversion was already installed without the SWIG bindings, you'll need to re-`configure` Subversion and `make swig-py`, `make install-swig-py`.
    54  * Support for other version control systems is provided via third-parties. See [http://projects.edgewall.com/trac/wiki/PluginList PluginList] and [http://projects.edgewall.com/trac/wiki/VersioningSystemBackend VersioningSystemBackend].
     75
     76===== Subversion =====
     77
     78[http://subversion.apache.org/ Subversion] 1.5.x or 1.6.x and the '''''corresponding''''' Python bindings.
     79
     80There are [http://subversion.apache.org/packages.html pre-compiled SWIG bindings] available for various platforms. See also the [trac:TracSubversion] page for details about Windows packages.
     81
     82Older versions starting from 1.4.0, etc. should still work. For troubleshooting information, check the [trac:TracSubversion#Troubleshooting TracSubversion] page. Versions prior to 1.4.0 won't probably work since trac uses svn core functionality (e.g. svn_path_canonicalize) that is not implemented in the python swig wrapper in svn <= 1.3.x (although it exists in the svn lib itself).
     83
     84Note that Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], neither does it work yet with the newer `ctype`-style bindings.
     85
     86'''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently [trac:#493 not supported].
     87
     88
     89===== Others =====
     90
     91Support for other version control systems is provided via third-parties. See [trac:PluginList] and [trac:VersionControlSystem].
    5592
    5693==== Web Server ====
    57  * A CGI-capable web server (see TracCgi), or
    58  * a [http://www.fastcgi.com/ FastCGI]-capable web server (see TracFastCgi), or
    59  * [http://httpd.apache.org/ Apache] with [http://www.modpython.org/ mod_python 3.1.3+] (see TracModPython)
    60     * When installing mod_python the development versions of Python and Apache are required (actually the libraries and header files)
    61 
    62 For those stuck with Apache 1.3, it is also possible to get Trac 0.8.4 working with [http://www.modpython.org/ mod_python 2.7] (see [wiki:TracModPython2.7 TracModPython2.7]). This hasn't been tested with Trac 0.9, so it may or may not work.
    63 
    64 ==== Other Python Utilities ====
    65  * [http://peak.telecommunity.com/DevCenter/setuptools setuptools], version >= 0.6 for using plugins (see TracPlugins)
    66  * [http://docutils.sourceforge.net/ docutils], version >= 0.3.9 for WikiRestructuredText.
    67  * [http://silvercity.sourceforge.net/ SilverCity] and/or [http://www.gnu.org/software/enscript/enscript.html Enscript] for [wiki:TracSyntaxColoring syntax highlighting].
    68     * Note that !SilverCity 0.9.6 has a [http://sourceforge.net/tracker/index.php?func=detail&aid=1424436&group_id=45693&atid=443739 bug] that breaks Python syntax highlighting in Trac. Until an update is made available, we recommend using version 0.9.5.
    69 
    70 '''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].
    71 
    72 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. Keep in mind however that the information there might concern older versions of Trac than the one you're installing (in particular,
    73 there are still some pages that are about Trac 0.8).
     94A web server is optional because Trac is shipped with a server included, see the [#RunningtheStandaloneServer Running the Standalone Server ] section below.
     95
     96Alternatively you configure Trac to run in any of the following environments.
     97 * [http://httpd.apache.org/ Apache] with
     98   - [http://code.google.com/p/modwsgi/ mod_wsgi], see [wiki:TracModWSGI] (preferred)
     99   - //[http://modpython.org/ mod_python 3.3.1], see TracModPython (deprecated)//
     100 * any [http://www.fastcgi.com/ FastCGI]-capable web server, see TracFastCgi
     101 * any [http://tomcat.apache.org/connectors-doc/ajp/ajpv13a.html AJP]-capable web
     102   server, see [trac:TracOnWindowsIisAjp]
     103 * IIS with [http://code.google.com/p/isapi-wsgi/ Isapi-wsgi], see [trac:TracOnWindowsIisIsapi]
     104 * //as a last resort, a CGI-capable web server (see TracCgi), but usage of Trac as a cgi script
     105   is highly discouraged, better use one of the previous options.//
     106   
     107
     108==== Other Python Packages ====
     109
     110 * [http://babel.edgewall.org Babel], version 0.9.5,
     111   needed for localization support[[BR]]
     112   ''Note: '' If you want to be able to use the Trac interface in other languages, then make sure you first have installed the optional package Babel. Lacking Babel, you will only get the default english version, as usual. If you install Babel later on, you will need to re-install Trac.
     113 * [http://docutils.sourceforge.net/ docutils], version >= 0.3.9
     114   for WikiRestructuredText.
     115 * [http://pygments.pocoo.org Pygments] for
     116   [wiki:TracSyntaxColoring syntax highlighting].
     117   [http://silvercity.sourceforge.net/ SilverCity] and/or
     118   [http://gnu.org/software/enscript/enscript.html Enscript] may still be used
     119   but are deprecated and you really should be using Pygments.
     120 * [http://pytz.sf.net pytz] to get a complete list of time zones,
     121   otherwise Trac will fall back on a shorter list from
     122   an internal time zone implementation.
     123
     124'''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].
     125
     126Please 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!).
     127
    74128
    75129== Installing Trac ==
    76 
    77 Like most Python programs, the Trac Python package is installed by running the following command at the top of the source directory:
     130=== Using `easy_install`
     131One way to install Trac is using [http://pypi.python.org/pypi/setuptools setuptools].
     132With setuptools you can install Trac from the subversion repository;
     133
     134A few examples:
     135
     136 - first install of the latest stable version Trac 0.12.3, with i18n support:
     137   {{{
     138   easy_install Babel==0.9.5
     139   easy_install Trac==0.12
     140   }}}
     141   ''It's very important to run the two `easy_install` commands separately, otherwise the message catalogs won't be generated.''
     142
     143 - upgrade to the latest stable version of Trac:
     144   {{{
     145   easy_install -U Trac
     146   }}}
     147
     148 - upgrade to the latest trunk development version:
     149   {{{
     150   easy_install -U Trac==dev
     151   }}}
     152
     153For upgrades, reading the TracUpgrade page is mandatory, of course.
     154
     155{{{#!div style="border: 1pt dotted; margin: 1em"
     156**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 the sections on [#RunningtheStandaloneServer Running The Standalone Server] and [#RunningTraconaWebServer Running Trac on a Web Server].
     157}}}
     158
     159=== From source
     160If you want more control, you can download the source in archive form, or do a checkout from one of the official [[Trac:TracRepositories|source code repositories]].
     161
     162Be sure to have the prerequisites already installed. You can also obtain the Genshi and Babel source packages from http://www.edgewall.org and follow for them a similar installation procedure, or you can just `easy_install` those, see [#Usingeasy_install above].
     163
     164Once you've unpacked the Trac archive or performed the checkout, move in the top-level folder and do:
    78165{{{
    79166$ python ./setup.py install
    80167}}}
    81168
    82 ''Note: you'll need root permissions or equivalent for this step.''
    83 
    84 This will byte-compile the python source code and install it in the `site-packages` directory
    85 of your Python installation. The directories `cgi-bin`, `templates`, `htdocs`, `wiki-default` and `wiki-macros` are all copied to `$prefix/share/trac/`. `conf` and `plugins` stub directories are also created under `$prefix/share/trac/` (''since [milestone:0.10]'').
     169You'll need root permissions or equivalent for this step.
     170
     171This will byte-compile the python source code and install it as an .egg file or folder in the `site-packages` directory
     172of your Python installation. The .egg will also contain all other resources needed by standard Trac, such as htdocs and templates.
    86173
    87174The 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.
    88175
     176If 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):
     177{{{
     178$ python ./setup.py install
     179}}}
     180Alternatively, 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`).
     181
    89182=== Advanced Options ===
    90183
     184==== Custom location with `easy_install`
     185
    91186To install Trac to a custom location, or find out about other advanced installation options, run:
    92187{{{
    93 $ python ./setup.py install --help
     188easy_install --help
    94189}}}
    95190
     
    98193Specifically, you might be interested in:
    99194{{{
    100 $ python ./setup.py install --prefix=/path/to/installdir
    101 }}}
     195easy_install --prefix=/path/to/installdir
     196}}}
     197or, if installing Trac to a Mac OS X system:
     198{{{
     199easy_install --prefix=/usr/local --install-dir=/Library/Python/2.5/site-packages
     200}}}
     201Note: 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
     202
     203The 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.
     204
     205==== Using `pip`
     206'pip' is an easy_install replacement that is very useful to quickly install python packages.
     207To get a trac installation up and running in less than 5 minutes:
     208
     209Assuming you want to have your entire pip installation in /opt/user/trac:
     210
     211 -
     212{{{
     213pip -E /opt/user/trac install trac psycopg2
     214}}}
     215or
     216 -
     217{{{
     218pip -E /opt/user/trac install trac mysql-python
     219}}}
     220
     221Make sure your OS specific headers are available for pip to automatically build PostgreSQL (libpq-dev) or MySQL (libmysqlclient-dev) bindings.
     222
     223pip 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 .
     224
     225All 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)
     226
     227Additionally, you can install several trac plugins (listed [http://pypi.python.org/pypi?:action=search&term=trac&submit=search here]) through pip.
     228
     229
    102230
    103231== Creating a Project Environment ==
    104232
    105 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.
     233A [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.
    106234
    107235A new environment is created using [wiki:TracAdmin trac-admin]:
     
    110238}}}
    111239
    112 [wiki:TracAdmin trac-admin] will prompt you for the information it needs to create the environment, such as the name of the project, the type and the path to an existing [wiki:TracEnvironment#SourceCodeRepository source code 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. Leaving the path to the source code repository empty will disable any functionality related to version control, but you can always add that back when the basic system is running.
    113 
    114 Also note that the values you specify here can be changed later by directly editing the [wiki:TracIni] configuration file.
    115 
    116 ''Note: The user account under which the web server runs will require write permissions to the environment
    117 directory and all the files inside.''
    118 
    119 
    120 == Running the Standalone Server ==
     240[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.
     241
     242Using the default database connection string in particular will always work as long as you have SQLite installed.
     243For the other [DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
     244
     245Since 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.
     246
     247Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file.
     248
     249Finally, 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:
     250{{{
     251# chown -R apache.apache /path/to/myproject
     252}}}
     253
     254{{{#!div class=important

     259== Deploying Trac
     260
     261=== Running the Standalone Server ===
    121262
    122263After having created a Trac environment, you can easily try the web interface by running the standalone server [wiki:TracStandalone tracd]:
     
    125266}}}
    126267
    127 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.
    128 
    129 
    130 == Running Trac on a Web Server ==
    131 
    132 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.
     268Then, 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:
     269{{{
     270$ tracd -s --port 8000 /path/to/myproject
     271}}}
     272
     273{{{#!div style="border: 1pt dotted; margin: 1em"
     274**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. 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.
     275
     276To 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`.
     277{{{#!sh
     278export PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1
     279}}}
     280
     281Alternatively, the variable can be set in the shell before executing `tracd`:
     282{{{#!sh
     283$ PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1 tracd --port 8000 /path/to/myproject
     284}}}
     285}}}
     286
     287=== Running Trac on a Web Server ===
     288
     289Trac provides various options for connecting to a "real" web server:
     290 - [wiki:TracFastCgi FastCGI]
     291 - [wiki:TracModWSGI mod_wsgi]
     292 - //[wiki:TracModPython mod_python] (no longer recommended, as mod_python is not actively maintained anymore)//
     293 - //[wiki:TracCgi CGI] (should not be used, as the performance is far from optimal)//
     294
     295Trac 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.
     296
     297==== Generating the Trac cgi-bin directory ==== #cgi-bin
     298
     299In 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].
     300
     301There 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:
     302{{{
     303mkdir -p /usr/share/trac/projects/my-project
     304trac-admin /usr/share/trac/projects/my-project initenv
     305trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy
     306mv /tmp/deploy/* /usr/share/trac
     307}}}
     308
     309
     310==== Mapping Static Resources ====
     311
     312Out 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).
     313
     314Web 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.
     315
     316There 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.
     317
     318Note 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:
     319[[TracAdminHelp(deploy)]]
     320
     321The target `<directory>` will then contain an `htdocs` directory with:
     322 - `site/` - a copy of the environment's directory `htdocs/`
     323 - `common/` - the static resources of Trac itself
     324 - `<plugins>/` - one directory for each resource directory managed by the plugins enabled for this environment
     325
     326===== Example: Apache and `ScriptAlias` ===== #ScriptAlias-example
     327
     328Assuming the deployment has been done this way:
     329{{{
     330$ trac-admin /var/trac/env deploy /path/to/trac/htdocs/common
     331}}}
     332
     333Add 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:
     334{{{
     335Alias /trac/chrome/common /path/to/trac/htdocs/common
     336Alias /trac/chrome/site /path/to/trac/htdocs/site
     337
     338<Directory "/path/to/www/trac/htdocs">
     339  Order allow,deny
     340  Allow from all
     341</Directory>
     342}}}
     343
     344If using mod_python, you might want to add this too (otherwise, the alias will be ignored):
     345{{{
     346<Location "/trac/chrome/common/">
     347  SetHandler None
     348</Location>
     349}}}
     350
     351Note 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.
     352
     353Similarly, 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):
     354{{{
     355Alias /trac/chrome/site /path/to/projectenv/htdocs
     356
     357<Directory "/path/to/projectenv/htdocs">
     358  Order allow,deny
     359  Allow from all
     360</Directory>
     361}}}
     362
     363Alternatively 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:
     364{{{
     365[trac]
     366htdocs_location = http://static.example.org/trac-common/
     367}}}
     368Note 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]).
     369
     370Of 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:
     371{{{
     372$ ln -s /path/to/trac/htdocs/common /var/www/static.example.org/trac-common
     373}}}
     374
     375
     376==== Setting up the Plugin Cache ====
     377
     378Some 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.

    134380== Configuring Authentication ==
    135381
    136 The process of adding, removing, and configuring user accounts for authentication depends on the specific way you run Trac. The basic procedure is described in the [wiki:TracCgi#AddingAuthentication "Adding Authentication"] section on the TracCgi page. To learn how to setup authentication for the frontend you're using, please refer to one of the following pages:
    137 
    138  * TracStandalone if you use the standalone server, `tracd`.
    139  * TracCgi if you use the CGI or FastCGI methods.
    140  * TracModPython if you use the mod_python method.
    141 
    142 == Using Trac ==
    143 
    144 Once you have your Trac site up and running, you should be able to browse your subversion repository, create tickets, view the timeline, etc.
    145 
    146 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.
     382Trac 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.
     383
     384The process of adding, removing, and configuring user accounts for authentication depends on the specific way you run Trac.
     385
     386Please refer to one of the following sections:
     387 * TracStandalone#UsingAuthentication if you use the standalone server, `tracd`.
     388 * [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`.
     389 * TracFastCgi if you're using another web server with FCGI support (Cherokee, Lighttpd, !LiteSpeed, nginx)
     390
     391== Granting admin rights to the admin user
     392Grant admin rights to user admin:
     393{{{
     394$ trac-admin /path/to/myproject permission add admin TRAC_ADMIN
     395}}}
     396This user will have an "Admin" entry menu that will allow you to admin your trac project.
     397
     398== Finishing the install
     399
     400=== Automatic reference to the SVN changesets in Trac tickets ===
     401
     402You 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:
     403 * '''`Refs #123`''' - to reference this changeset in `#123` ticket
     404 * '''`Fixes #123`''' - to reference this changeset and close `#123` ticket with the default status ''fixed''
     405
     406This 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.
     407{{{
     408tracopt.ticket.commit_updater.* = enabled
     409}}}
     410For more information, see the documentation of the `CommitTicketUpdater` component in the "Plugins" admin panel.
     411
     412=== Using Trac ===
     413
     414Once 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.
     415
     416Keep 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.
