    22[[TracGuideToc]]
    33
    4 
    5 Trac is written in the Python programming language and needs a database, [http://sqlite.org/ SQLite], [http://postgresql.org/ PostgreSQL], [http://mysql.com/ MySQL]. For HTML rendering, Trac uses the [http://genshi.edgewall.org Genshi] templating system.
    6 
    7 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 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 
    9 See TracUpgrade for instructions on how to upgrade an existing installation.
    10 
    11 
    12 == Quick Install a Released Version ==
    13 For a quick install, first make sure you have [http://python.org/download Python] (2.3-2.6) and [http://peak.telecommunity.com/DevCenter/EasyInstall#installing-easy-install easy_install].
    14 
    15 Then enter (''omit 'sudo' if not applicable'')
    16 {{{
    17 sudo easy_install Trac
    18 }}}
    19 to install Trac, SQLite, and Genshi.
    20 
    21 
    22 == Requirements ==
    23 The hardware requirements for running Trac obviously depend on the expected data volume (number of wiki pages, tickets, revisions) and traffic. Very small projects will run fine with a 500MHz processor and 128MB RAM using SQLite. In general, the more RAM, the better. A fast hard disk also helps.
    24 
     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].
     9
     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.

     13
     14== Dependencies ==
     15=== Mandatory Dependencies
    2516To install Trac, the following software packages must be installed:
    2617
    27  * [http://www.python.org/ Python], version >=2.3 (<3.0)
    28    * if using mod_python together with xml-related things, use python-2.5. expat is namespaced there and does not cause apache to crash any more(see [http://www.dscpl.com.au/wiki/ModPython/Articles/ExpatCausingApacheCrash here] for details).
    29    * For RPM-based systems you might also need the `python-devel` and `python-xml` packages.
    30    * See instructions in [trac:wiki:TracOnWindows/Python2.5 TracOnWindows/Python2.5]
    31  * [trac:wiki:setuptools setuptools], version >= 0.6
    32  * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.5 (was version >= 0.4.1 on previous 0.11 release candidates)
    33  * You also need a database system and the corresponding python drivers for it.
    34    The database can be either SQLite, PostgreSQL or MySQL.
    35  * Optional if some plugins require it: [http://www.clearsilver.net/ ClearSilver] (for information on installing ClearSilver refer to the [wiki:0.10/TracInstall#Requirements 0.10/TracInstall] page and the Trac:ClearSilver page).
    36 
    37 ==== For SQLite ====
     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
    3827
    3928If you're using Python 2.5 or 2.6, you already have everything you need.
    4029
    41 If you're using Python 2.3 or 2.4 and need pysqlite, you can download from
    42 [http://code.google.com/p/pysqlite/downloads/list google code] the Windows
    43 installers or the tar.gz archive for building from source:
     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:
    4432{{{
    4533$ tar xvfz <version>.tar.gz
     
    4836}}}
    4937 
    50 That way, the latest SQLite version will be downloaded and built into the
    51 bindings.
    52 
    53 If you're still using SQLite 2.x, you'll need pysqlite 1.0.x, although this
    54 package is not easy to find anymore. For SQLite 3.x, try not to use
    55 pysqlite 1.1.x, which has been deprecated in favor of pysqlite 2.x.
    56 
    57 See additional information in [trac:PySqlite PySqlite].
    58 
    59 ==== For PostgreSQL ====
    60 
    61  * [http://www.postgresql.org/ PostgreSQL]
    62  * [http://initd.org/projects/psycopg2 psycopg2]
    63  * See [trac:wiki:DatabaseBackend#Postgresql DatabaseBackend]
    64 
    65 '''Warning''': PostgreSQL 8.3 uses a strict type checking mechanism. To use Trac with the 8.3 Version of PostgreSQL, you will need [http://trac.edgewall.org/changeset/6512 trac-0.11] or later.
    66 
    67 ==== For MySQL ====
    68 
    69  * [http://mysql.com/ MySQL], version 4.1 or later ([http://askmonty.org/wiki/index.php/MariaDB MariaDB] might work as well)
    70  * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.1 or later
    71 
    72 See [trac:MySqlDb MySqlDb] for more detailed information.
    73 It is ''very'' important to read carefully that page before creating the database.
    74 
    75 == Optional Requirements ==
     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
    7673
    7774==== Version Control System ====
    7875
    79 '''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently not supported (although Windows UNC paths such as {{{\\machine_name\path\to\svn}}} do work).
    80 
    81  * [http://subversion.tigris.org/ Subversion], version >= 1.0. (versions recommended: 1.2.4, 1.3.2 or 1.4.2) and the '''''corresponding''''' Python bindings. For troubleshooting, check [trac:TracSubversion TracSubversion]
    82    * Trac uses the [http://svnbook.red-bean.com/svnbook-1.1/ch08s02.html#svn-ch-8-sect-2.3 SWIG] bindings included in the Subversion distribution, '''not''' [http://pysvn.tigris.org/ PySVN] (which is sometimes confused with the standard SWIG bindings).
    83    * If Subversion was already installed without the SWIG bindings, on Unix you'll need to re-`configure` Subversion and `make swig-py`, `make install-swig-py`.
    84    * There are [http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91 pre-compiled bindings] available for win32.
    85  * Support for other version control systems is provided via third-parties. See [trac:PluginList PluginList] and [trac:VersioningSystemBackend VersioningSystemBackend].
     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 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].
    8692
    8793==== Web Server ====
    88 One of the following web servers:
    89  * A CGI-capable web server (see TracCgi), or
    90  * a [http://www.fastcgi.com/ FastCGI]-capable web server (see TracFastCgi), or
    91  * an [http://tomcat.apache.org/connectors-doc/ajp/ajpv13a.html AJP]-capable web server (see [trac:TracOnWindowsIisAjp TracOnWindowsIisAjp]), or
    92  * [http://httpd.apache.org/ Apache] with [http://code.google.com/p/modwsgi/ mod_wsgi] (see [wiki:TracModWSGI] or http://code.google.com/p/modwsgi/wiki/IntegrationWithTrac) or
    93     * This should work with Apache 1.3, 2.0 or 2.2 and promises to deliver more performance than using mod_python. A little less mature than mod_python.
    94     * You shouldn't use aliases for svn repos. For example, project located at /usr/local/www/trac, http://host/trac. And you want url http://host/trac/svn to point to the repo. You should define symlink ''ln -s /path/to/your/repo /usr/loca/www/trac/svn'', because with ''httpd.conf:Alias /trac/svn /path/to/your/repo'' repo will be unaccessible via http.
    95  * [http://httpd.apache.org/ Apache] with [http://www.modpython.org/ mod_python 3.1.3+] (see TracModPython)
    96     * When installing mod_python the development versions of Python and Apache are required (actually the libraries and header files)
    97 
    98 For those stuck with Apache 1.3, it is also possible to get Trac working with [http://www.modpython.org/ mod_python 2.7] (see [trac:wiki:TracModPython2.7 TracModPython2.7]). This guide hasn't been updated since 0.84, so it may or may not work.
    99 
    100 ==== Other Python Utilities ====
    101  * [http://docutils.sourceforge.net/ docutils], version >= 0.3.9 for WikiRestructuredText.
    102  * [http://pygments.pocoo.org Pygments] for '''syntax highlighting''', although [http://silvercity.sourceforge.net/ SilverCity] >= 0.9.7 and/or [http://gnu.org/software/enscript/enscript.html GNU Enscript] are also possible. Refer to TracSyntaxColoring for details.
    103  * [http://pytz.sf.net pytz] to get a complete list of time zones, otherwise Trac will fall back on a shorter list from an internal time zone implementation.
    104 
    105 '''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 MailingList] or [trac:IrcChannel IrcChannel].
     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].
    106125
    107126Please 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!).
    108127
     128
    109129== Installing Trac ==
    110 
    111 One way to install Trac is using `setuptools`.
    112 With setuptools you can install Trac from the subversion repository; for example,
    113 to install release version 0.11 do:
    114 {{{
    115 easy_install http://svn.edgewall.org/repos/trac/tags/trac-0.11
    116 }}}
    117 
    118 But of course the python-typical setup at the top of the source directory also works:
     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=== From source
     156If 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]].
     157
     158Be 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].
     159
     160Once you've unpacked the Trac archive or performed the checkout, move in the top-level folder and do:
    119161{{{
    120162$ python ./setup.py install
    121163}}}
    122164
    123 ''Note: you'll need root permissions or equivalent for this step.''
     165You'll need root permissions or equivalent for this step.
    124166
    125167This will byte-compile the python source code and install it as an .egg file or folder in the `site-packages` directory
     
    128170The 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.
    129171
    130 ==== Advanced Options ====
     172If 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):
     173{{{
     174$ python ./setup.py install
     175}}}
     176Alternatively, 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`).
     177
     178=== Advanced Options ===
     179
     180==== Custom location with `easy_install`
    131181
    132182To install Trac to a custom location, or find out about other advanced installation options, run:
     
    145195easy_install --prefix=/usr/local --install-dir=/Library/Python/2.5/site-packages
    146196}}}
     197Note: 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
    147198
    148199The 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.
    149200
     201==== Using `pip`
     202'pip' is an easy_install replacement that is very useful to quickly install python packages.
     203To get a trac installation up and running in less than 5 minutes:
     204
     205Assuming you want to have your entire pip installation in /opt/user/trac:
     206
     207 -
     208{{{
     209pip -E /opt/user/trac install trac psycopg2
     210}}}
     211or
     212 -
     213{{{
     214pip -E /opt/user/trac install trac mysql-python
     215}}}
     216
     217Make sure your OS specific headers are available for pip to automatically build PostgreSQL (libpq-dev) or MySQL (libmysqlclient-dev) bindings.
     218
     219pip 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 .
     220
     221All 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)
     222
     223Additionally, you can install several trac plugins (listed [http://pypi.python.org/pypi?:action=search&term=trac&submit=search here]) through pip.
     224
     225
     226
    150227== Creating a Project Environment ==
    151228
    152 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.
     229A [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.
    153230
    154231A new environment is created using [wiki:TracAdmin trac-admin]:
     
    157234}}}
    158235
    159 [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.
    160 
    161 Also note that the values you specify here can be changed later by directly editing the [wiki:TracIni] configuration file.

    167 == Running the Standalone Server ==
     236[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.
     237
     238Using the default database connection string in particular will always work as long as you have SQLite installed.
     239For the other [DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
     240
     241Since 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.
     242
     243Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file.
     244
     245Finally, 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:
     246{{{
     247# chown -R apache.apache /path/to/myproject
     248}}}

     255== Deploying Trac
     256
     257=== Running the Standalone Server ===
    168258
    169259After having created a Trac environment, you can easily try the web interface by running the standalone server [wiki:TracStandalone tracd]:
     
    172262}}}
    173263
    174 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. 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:
     264Then, 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:
    175265{{{
    176266$ tracd -s --port 8000 /path/to/myproject
    177267}}}
    178268
    179 == Running Trac on a Web Server ==
    180 
    181 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.
    182 
    183 If you're not afraid of running newer code, you can also try running Trac on [wiki:TracModWSGI mod_wsgi]. This should deliver even better performance than mod_python, but the module isn't as extensively tested as mod_python.
    184 
    185 Trac also supports [trac:TracOnWindowsIisAjp AJP] which may be your choice if you want to connect to IIS.
    186 
    187 ==== Generating the Trac cgi-bin directory ====
    188 
    189 In order for Trac to function properly with FastCGI or mod_python, you need to have a trac.cgi file. This is an executable which loads the appropriate Python code. It can be generated using the `deploy` option of [wiki:TracAdmin trac-admin].
     269=== Running Trac on a Web Server ===
     270
     271Trac provides various options for connecting to a "real" web server:
     272 - [wiki:TracFastCgi FastCGI]
     273 - [wiki:TracModWSGI mod_wsgi]
     274 - //[wiki:TracModPython mod_python] (no longer recommended, as mod_python is not actively maintained anymore)//
     275 - //[wiki:TracCgi CGI] (should not be used, as the performance is far from optimal)//
     276
     277Trac 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.
     278
     279==== Generating the Trac cgi-bin directory ==== #cgi-bin
     280
     281In 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].
    190282
    191283There 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:
     
    197289}}}
    198290
     291
     292==== Mapping Static Resources ====
     293
     294Out 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).
     295
     296Web 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.
     297
     298There 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.
     299
     300Note 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:
     301[[TracAdminHelp(deploy)]]
     302
     303The target `<directory>` will then contain an `htdocs` directory with:
     304 - `site/` - a copy of the environment's directory `htdocs/`
     305 - `common/` - the static resources of Trac itself
     306 - `<plugins>/` - one directory for each resource directory managed by the plugins enabled for this environment
     307
     308===== Example: Apache and `ScriptAlias` ===== #ScriptAlias-example
     309
     310Assuming the deployment has been done this way:
     311{{{
     312$ trac-admin /var/trac/env deploy /path/to/trac/htdocs/common
     313}}}
     314
     315Add 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:
     316{{{
     317Alias /trac/chrome/common /path/to/trac/htdocs/common
     318Alias /trac/chrome/site /path/to/trac/htdocs/site
     319
     320<Directory "/path/to/www/trac/htdocs">
     321  Order allow,deny
     322  Allow from all
     323</Directory>
     324}}}
     325
     326If using mod_python, you might want to add this too (otherwise, the alias will be ignored):
     327{{{
     328<Location "/trac/chrome/common/">
     329  SetHandler None
     330</Location>
     331}}}
     332
     333Note 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.
     334
     335Similarly, 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):
     336{{{
     337Alias /trac/chrome/site /path/to/projectenv/htdocs
     338
     339<Directory "/path/to/projectenv/htdocs">
     340  Order allow,deny
     341  Allow from all
     342</Directory>
     343}}}
     344
     345Alternatively 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:
     346{{{
     347[trac]
     348htdocs_location = http://static.example.org/trac-common/
     349}}}
     350Note 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]).
     351
     352Of 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:
     353{{{
     354$ ln -s /path/to/trac/htdocs/common /var/www/static.example.org/trac-common
     355}}}
     356
     357
    199358==== Setting up the Plugin Cache ====
    200359
    201 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.

    203362== Configuring Authentication ==
    204363
    205 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:
    206 
    207  * TracStandalone if you use the standalone server, `tracd`.
    208  * TracCgi if you use the CGI or FastCGI methods.
    209  * TracModPython if you use the mod_python method.
    210 
    211 == Automatic reference to the SVN changesets in Trac tickets ==
    212 
    213 You can configure SVN to automatically add a reference to the changeset into the ticket comments, whenever files are committed to the repository. The description of the commit needs to contain one of the following formulas:
    214  * '''Refs #123''' - to reference this changeset in #123 ticket
    215  * '''Fixes #123''' - to reference this changeset and close #123 ticket with the default status ''fixed''
    216 
    217 All you have to do is to edit the ''post-commit'' hook in your SVN repository and make it execute ''trac-post-commit-hook'' coming with Trac.
    218 
    219 If you are editing the ''post-commit'' hook for the first time you need to navigate to your SVN repository's hooks subfolder and rename existing there ''post-commit'' template:
    220 
    221 {{{
    222 $ cd /path/to/svn/repository/hooks
    223 $ mv post-commit.tmpl post-commit
    224 $ chmod 755 post-commit
    225 }}}
    226 
    227 Next open it in any text editor and add a line with path to the Trac environment connected with this SVN repository and another line executing the ''trac-post-commit-hook'' script:
    228 
    229 {{{
    230 REPOS="$1"
    231 REV="$2"
    232 TRAC_ENV="/path/to/your/trac/project"
    233 
    234 /usr/bin/python /usr/local/bin/trac-post-commit-hook -p "$TRAC_ENV" -r "$REV"
    235 }}}
    236 
    237 Make sure that ''trac-post-commit-hook'' exists in above path with execution permissions for the same user which SVN is running from. This script can be found in contrib subfolder of your Trac distribution and the latest version can be always downloaded from [trac:source:branches/0.11-stable/contrib/trac-post-commit-hook branches/0.11-stable/contrib/trac-post-commit-hook].
    238 
    239 
    240 == Platform-specifics installations ==
    241 
    242  * See [trac:TracInstallPlatforms TracInstallPlatforms]
    243  
    244 
    245 == Using Trac ==
    246 
    247 Once you have your Trac site up and running, you should be able to browse your subversion repository, create tickets, view the timeline, etc.
    248 
    249 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.
     364Trac 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
     366The process of adding, removing, and configuring user accounts for authentication depends on the specific way you run Trac.
     367
     368Please refer to one of the following sections:
     369 * TracStandalone#UsingAuthentication if you use the standalone server, `tracd`.
     370 * [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`.
     371 * TracFastCgi if you're using another web server with FCGI support (Cherokee, Lighttpd, !LiteSpeed, nginx)
     372
     373== Granting admin rights to the admin user
     374Grant admin rights to user admin:
     375{{{
     376$ trac-admin /path/to/myproject permission add admin TRAC_ADMIN
     377}}}
     378This user will have an "Admin" entry menu that will allow you to admin your trac project.
     379
     380== Finishing the install
     381
     382=== Automatic reference to the SVN changesets in Trac tickets ===
     383
     384You 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:
     385 * '''`Refs #123`''' - to reference this changeset in `#123` ticket
     386 * '''`Fixes #123`''' - to reference this changeset and close `#123` ticket with the default status ''fixed''
     387
     388This 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.
     389{{{
     390tracopt.ticket.commit_updater.* = enabled
     391}}}
     392For more information, see the documentation of the `CommitTicketUpdater` component in the "Plugins" admin panel.
     393
     394=== Using Trac ===
     395
     396Once 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.
     397
     398Keep 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.
