    44Trac 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.
    55
    6 Since version 0.12, Trac can also be localized, and there's probably a translation available for your language. If you want to be able to use the Trac interface in other languages, then make sure you **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.
     6Since version 0.12, Trac can also be localized, and there is probably a translation available in your language. If you want to use the Trac interface in other languages, then make sure you have installed the optional package [#OtherPythonPackages Babel]. Pay attention to the extra steps for localization support in the [#InstallingTrac Installing Trac] section below. Lacking Babel, you will only get the default English version.

    88If 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].

     14== Dependencies
    1515=== Mandatory Dependencies
    1616To install Trac, the following software packages must be installed:
    1717
    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)
     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)
    2020 * [http://peak.telecommunity.com/DevCenter/setuptools setuptools], version >= 0.6
    2121 * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.6
    2222
    23 You also need a database system and the corresponding python bindings.
    24 The database can be either SQLite, PostgreSQL or MySQL.
     23You also need a database system and the corresponding python bindings. The database can be either SQLite, PostgreSQL or MySQL.
    2524
    2625==== For the SQLite database #ForSQLite
    2726
    28 If you're using Python 2.5 or 2.6, you already have everything you need.
    29 
    30 If 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 {{{
     27As 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.
     28
     29However, if you like, you can download the latest and greatest version of [[trac:PySqlite]] from
     30[http://code.google.com/p/pysqlite/downloads/list google code], where you'll find the Windows
     31installers or the `tar.gz` archive for building from source:
     32{{{#!sh
    3333$ tar xvfz <version>.tar.gz
    3434$ cd <version>
     
    3636}}}
    3737 
    38 This will extract the SQLite code and build the bindings.
    39 
    40 To 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 
    46 SQLite 2.x is no longer supported, and neither is !PySqlite 1.1.x.
    47 
    48 A known bug !PySqlite versions 2.5.2-4 prohibits upgrade of trac databases
    49 from 0.11.x to 0.12. Please use versions 2.5.5 and newer or 2.5.1 and
    50 older. See [trac:#9434] for more detail.
    51 
    52 See additional information in [trac:PySqlite].
     38This will download the latest SQLite code and build the bindings. SQLite 2.x is no longer supported.
     39
     40A known bug in [trac:PySqlite] versions 2.5.2-4 prohibits upgrades of Trac databases from 0.11.x to 0.12. Please use versions 2.5.5 and newer or 2.5.1 and older. See #9434 for more detail. See additional information in [trac:PySqlite PySqlite].
    5341
    5442==== For the PostgreSQL database #ForPostgreSQL
     
    5644You need to install the database and its Python bindings:
    5745 * [http://www.postgresql.org/ PostgreSQL], version 8.0 or later
    58  * [http://pypi.python.org/pypi/psycopg2 psycopg2]
     46 * [http://pypi.python.org/pypi/psycopg2 psycopg2], version 2.0 or later
    5947
    6048See [trac:DatabaseBackend#Postgresql DatabaseBackend] for details.
    6149
    62 
    6350==== For the MySQL database #ForMySQL
    6451
    65 Trac can now work quite well with MySQL, provided you follow the guidelines.
     52Trac works well with MySQL, provided you follow the guidelines:
    6653
    6754 * [http://mysql.com/ MySQL], version 5.0 or later
    6855 * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.2 or later
    6956
    70 It is '''very''' important to read carefully the [trac:MySqlDb] page before creating the database.
     57Given the caveats and known issues surrounding MySQL, read carefully the [trac:MySqlDb] page before creating the database.

    7259=== Optional Dependencies
    7360
    74 ==== Version Control System ====
    75 
    76 ===== Subversion =====
    77  * [http://subversion.apache.org/ Subversion], 1.5.x or 1.6.x and the '''''corresponding''''' Python bindings. Older 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).
    78 
    79 There are [http://subversion.apache.org/packages.html pre-compiled SWIG bindings] available for various platforms. (Good luck finding precompiled SWIG bindings for any Windows package at that listing. TracSubversion points you to [http://alagazam.net Algazam], which works for me under Python 2.6.)
    80 
    81 Note that Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], neither does it work yet with the newer `ctype`-style bindings. [Is there a ticket for implementing ctype bindings?]
    82 
     61==== Version Control System
     62
     63===== Subversion
     64 * [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.

    87 ===== Others =====
    88 
    89 Support for other version control systems is provided via third-parties. See [trac:PluginList] and [trac:VersioningSystemBackend].
    90 
    91 ==== Web Server ====
    92 A web server is optional because Trac is shipped with a server included, see the [#RunningtheStandaloneServer Running the Standalone Server ] section below.
    93 
    94 Alternatively you configure Trac to run in any of the following environments.

    122 '''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].
    123 
    124 Please refer to the documentation of these packages to find out how they are best installed. In addition, most of the [trac:TracInstallPlatforms platform-specific instructions] also describe the installation of the dependencies. Keep in mind however that the information there ''probably concern older versions of Trac than the one you're installing'' (there are even some pages that are still talking about Trac 0.8!).

     110== Installing Trac
    128111=== Using `easy_install`
    129 One way to install Trac is using [http://pypi.python.org/pypi/setuptools setuptools].
    130 With setuptools you can install Trac from the subversion repository;
     112One way to install Trac is using [http://pypi.python.org/pypi/setuptools setuptools]. With setuptools you can install Trac from the Subversion repository.
    131113
    132114A few examples:
    133115
    134  - first install of the latest stable version Trac 0.12.1, with i18n support:
    135    {{{
    136    easy_install Babel==0.9.5 Genshi==0.6
    137    easy_install Trac
     116 - Install Trac 1.0:
     117   {{{#!sh
     118   easy_install Trac==1.0
    138119   }}}
    139    ''It's very important to run the two `easy_install` commands separately, otherwise the message catalogs won't be generated.''
    140 
    141  - upgrade to the latest stable version of Trac:
    142    {{{
    143    easy_install -U Trac
     120 - Install latest development version:
     121   {{{#!sh
     122   easy_install Trac==dev
    144123   }}}
    145 
    146  - upgrade to the latest trunk development version (0.13dev):
    147    {{{
    148    easy_install -U Trac==dev
    149    }}}
    150 
    151 For upgrades, reading the TracUpgrade page is mandatory, of course.
    152 
    153 === From source
    154 If 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]].
    155 
    156 Be 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].
    157 
    158 Once you've unpacked the Trac archive or performed the checkout, move in the top-level folder and do:
    159 {{{
    160 $ python ./setup.py install
    161 }}}
    162 
    163 ''You'll need root permissions or equivalent for this step.''
    164 
    165 This will byte-compile the python source code and install it as an .egg file or folder in the `site-packages` directory
    166 of your Python installation. The .egg will also contain all other resources needed by standard Trac, such as htdocs and templates.
    167 
    168 The script will also install the [wiki:TracAdmin trac-admin] command-line tool, used to create and maintain [wiki:TracEnvironment project environments], as well as the [wiki:TracStandalone tracd] standalone server.
    169 
    170 If you install from source and want to make Trac available in other languages, make sure  Babel is installed. Only then, perform the `install` (or simply redo the `install` once again afterwards if you realize Babel was not yet installed):
    171 {{{
    172 $ python ./setup.py install
    173 }}}
    174 Alternatively, 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`).
    175 
    176 === Advanced Options ===
    177 
    178 To install Trac to a custom location, or find out about other advanced installation options, run:
    179 {{{
    180 easy_install --help
    181 }}}
    182 
    183 Also see [http://docs.python.org/inst/inst.html Installing Python Modules] for detailed information.
    184 
    185 Specifically, you might be interested in:
    186 {{{
    187 easy_install --prefix=/path/to/installdir
    188 }}}
    189 or, if installing Trac to a Mac OS X system:
    190 {{{
    191 easy_install --prefix=/usr/local --install-dir=/Library/Python/2.5/site-packages
    192 }}}
    193 Note: 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
    194 
    195 The 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.
     124   Note that in this case you won't have the possibility to run a localized version of Trac;
     125   either use a released version or install from source
     126
     127{{{#!div style="border: 1pt dotted; margin: 1em"
     128**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].
     129}}}
    196130
    197131=== Using `pip`
    198132'pip' is an easy_install replacement that is very useful to quickly install python packages.
    199 To get a trac installation up and running in less than 5 minutes:

    212 
    213 Make sure your OS specific headers are available for pip to automatically build PostgreSQL (libpq-dev) or MySQL (libmysqlclient-dev) bindings.
    214 
    215 pip will automatically resolve all dependencies (like Genshi, pygments, etc.) and download the latest packages on pypi.python.org and create a self contained installation in /opt/user/trac .
    216 
    217 All commands (tracd, trac-admin) are available in /opt/user/trac/bin. This can also be leveraged for mod_python (using !PythonHandler directive) and mod_wsgi (using WSGIDaemonProcess directive)
    218 
    219 Additionally, you can install several trac plugins (listed [http://pypi.python.org/pypi?:action=search&term=trac&submit=search here]) through pip.
    220 
    221 
    222 
    223 == Creating a Project Environment ==
    224 
    225 A [TracEnvironment Trac environment] is the backend storage where Trac stores information like wiki pages, tickets, reports, settings, etc. An environment is basically a directory that contains a human-readable [TracIni configuration file], and various other files and directories.
     143 {{{#!sh
     144pip install trac mysql-python
     145}}}
     146
     147Make sure your OS specific headers are available for pip to automatically build PostgreSQL (`libpq-dev`) or MySQL (`libmysqlclient-dev`) bindings.
     148
     149pip 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`.
     150
     151All 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)
     152
     153Additionally, you can install several Trac plugins (listed [https://pypi.python.org/pypi?:action=browse&show=all&c=516 here]) through pip.
     154
     155=== From source
     156Of course, using the python-typical setup at the top of the source directory also works. You can obtain the source for a .tar.gz or .zip file corresponding to a release (e.g. `Trac-1.0.tar.gz`), or you can get the source directly from the repository. See [trac:SubversionRepository] for details.

     164This will byte-compile the Python source code and install it as an .egg file or folder in the `site-packages` directory
     165of your Python installation. The .egg will also contain all other resources needed by standard Trac, such as `htdocs` and `templates`.

     167The 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.
     168
     169If 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):
     170{{{#!sh

     192Note: 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.
     193
     194The 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.

     196== Creating a Project Environment
     197
     198A [TracEnvironment Trac environment] is the backend 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 other files and directories.
    226199
    227200A new environment is created using [wiki:TracAdmin trac-admin]:
    228 {{{
     201{{{#!sh
    229202$ trac-admin /path/to/myproject initenv
    230203}}}
     
    235208For the other [DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
    236209
    237 Since 0.12, Trac doesn't ask for a [TracEnvironment#SourceCodeRepository source code repository] anymore when creating an environment. Repositories can be [TracRepositoryAdmin added] afterward, or the version control support can be disabled completely if you don't need it.
     210Since 0.12, Trac doesn't ask for a [TracEnvironment#SourceCodeRepository source code repository] anymore when creating an environment. Repositories can be [TracRepositoryAdmin added] afterwards, and support for specific version control systems is disabled by default.
    238211
    239212Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file.
    240213
     214When selecting the location of your environment, make sure that the filesystem on which the environment directory resides supports sub-second timestamps (i.e. **not** `ext2` or `ext3` on Linux), as the modification time of the `conf/trac.ini` file will be monitored to decide whether an environment restart is needed or not. A too coarse-grained timestamp resolution may result in inconsistencies in Trac < 1.0.2. The best advice is to opt for a platform with sub-second timestamp resolution, regardless of the Trac version.
     215
    241216Finally, 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:
    242 {{{
    243 # chown -R apache.apache /path/to/myproject
    244 }}}
     217{{{#!sh
     218$ chown -R apache.apache /path/to/myproject
     219}}}
     220
     221The actual username and groupname of the apache server may not be exactly `apache`, and are specified in the Apache configuration file by the directives `User` and `Group` (if Apache `httpd` is what you use).
    245222
    246223{{{#!div class=important

    250 
    251 == Running the Standalone Server ==
     227== Deploying Trac
     228
     229=== Running the Standalone Server
    252230
    253231After having created a Trac environment, you can easily try the web interface by running the standalone server [wiki:TracStandalone tracd]:
    254 {{{
     232{{{#!sh
    255233$ tracd --port 8000 /path/to/myproject
    256234}}}
    257235
    258236Then, 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:
    259 {{{
     237{{{#!sh
    260238$ tracd -s --port 8000 /path/to/myproject
    261239}}}
    262240
    263 == Running Trac on a Web Server ==
    264 
    265 Trac provides various options for connecting to a "real" web server: [wiki:TracCgi CGI], [wiki:TracFastCgi FastCGI], [wiki:TracModWSGI mod_wsgi] and [wiki:TracModPython mod_python]. For decent performance, it is recommended that you use either FastCGI or mod_wsgi.
    266 
    267 Trac also supports [trac:TracOnWindowsIisAjp AJP] which may be your choice if you want to connect to IIS.
    268 
    269 ==== Generating the Trac cgi-bin directory ====
     241{{{#!div style="border: 1pt dotted; margin: 1em"
     242**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.
     243
     244To 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`.
     245{{{#!sh
     246export PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1
     247}}}
     248
     249Alternatively, the variable can be set in the shell before executing `tracd`:
     250{{{#!sh
     251$ PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1 tracd --port 8000 /path/to/myproject
     252}}}
     253}}}
     254
     255=== Running Trac on a Web Server
     256
     257Trac provides various options for connecting to a "real" web server:
     258 - [wiki:TracFastCgi FastCGI]
     259 - [wiki:TracModWSGI mod_wsgi]
     260 - //[wiki:TracModPython mod_python] (no longer recommended, as mod_python is not actively maintained anymore)//
     261 - //[wiki:TracCgi CGI] (should not be used, as the performance is far from optimal)//
     262
     263Trac 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.
     264
     265==== Generating the Trac cgi-bin directory #cgi-bin
    270266
    271267In 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].
    272268
    273269There 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:
    274 {{{
     270{{{#!sh
    275271mkdir -p /usr/share/trac/projects/my-project
    276272trac-admin /usr/share/trac/projects/my-project initenv
     
    278274mv /tmp/deploy/* /usr/share/trac
    279275}}}
    280 
    281 ==== Setting up the Plugin Cache ====
    282 
    283 Some Python plugins need to be extracted to a cache directory. By default the cache resides in the home directory of the current user. When running Trac on a Web Server as a dedicated user (which is highly recommended) who has no home directory, this might prevent the plugins from starting. To override the cache location you can set the PYTHON_EGG_CACHE environment variable. Refer to your server documentation for detailed instructions on how to set environment variables.
    284 
    285 == Configuring Authentication ==
    286 
    287 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:
    288 
    289  * TracStandalone if you use the standalone server, `tracd`.
    290  * TracCgi if you use the CGI or FastCGI web front ends.
    291  * [wiki:TracModWSGI] if you use the Apache mod_wsgi web front end.
    292  * TracModPython if you use the Apache mod_python web front end.
    293 
    294 
    295 == Automatic reference to the SVN changesets in Trac tickets ==
     276Don't forget to check that the web server has the execution right on scripts in the `/usr/share/trac/cgi-bin` directory.
     277
     278==== Mapping Static Resources
     279
     280Out 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).
     281
     282Web 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.
     283
     284There 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.
     285
     286Note 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:
     287[[TracAdminHelp(deploy)]]
     288
     289The target `<directory>` will then contain an `htdocs` directory with:
     290 - `site/` - a copy of the environment's directory `htdocs/`
     291 - `common/` - the static resources of Trac itself
     292 - `<plugins>/` - one directory for each resource directory managed by the plugins enabled for this environment
     293
     294===== Example: Apache and `ScriptAlias` #ScriptAlias-example
     295
     296Assuming the deployment has been done this way:
     297{{{#!sh
     298$ trac-admin /var/trac/env deploy /path/to/shared/trac
     299}}}
     300
     301Add 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:
     302{{{#!apache
     303Alias /trac/chrome/common /path/to/trac/htdocs/common
     304Alias /trac/chrome/site /path/to/trac/htdocs/site
     305
     306<Directory "/path/to/www/trac/htdocs">
     307  Order allow,deny
     308  Allow from all
     309</Directory>
     310}}}
     311
     312If using mod_python, you might want to add this too (otherwise, the alias will be ignored):
     313{{{#!apache
     314<Location "/trac/chrome/common/">
     315  SetHandler None
     316</Location>
     317}}}
     318
     319Note 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.
     320
     321Similarly, 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):
     322{{{#!apache
     323Alias /trac/chrome/site /path/to/projectenv/htdocs
     324
     325<Directory "/path/to/projectenv/htdocs">
     326  Order allow,deny
     327  Allow from all
     328</Directory>
     329}}}
     330
     331Alternatively 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:
     332{{{#!ini
     333[trac]
     334htdocs_location = http://static.example.org/trac-common/
     335}}}
     336Note 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]).
     337
     338Of 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:
     339{{{#!sh
     340$ ln -s /path/to/trac/htdocs/common /var/www/static.example.org/trac-common
     341}}}
     342
     343==== Setting up the Plugin Cache
     344
     345Some 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.
     346
     347== Configuring Authentication
     348
     349Trac 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.
     350
     351The process of adding, removing, and configuring user accounts for authentication depends on the specific way you run Trac.
     352
     353Please refer to one of the following sections:
     354 * TracStandalone#UsingAuthentication if you use the standalone server, `tracd`.
     355 * [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`.
     356 * TracFastCgi if you're using another web server with FCGI support (Cherokee, Lighttpd, !LiteSpeed, nginx)
     357
     358The following document also constains some useful information for beginners: [trac:TracAuthenticationIntroduction].
     359
     360== Granting admin rights to the admin user
     361Grant admin rights to user admin:
     362{{{#!sh
     363$ trac-admin /path/to/myproject permission add admin TRAC_ADMIN
     364}}}
     365This user will have an "Admin" entry menu that will allow you to administrate your Trac project.
     366
     367== Finishing the install
     368
     369=== Enable version control components
     370
     371Support for version control systems is provided by optional components in Trac and the components are disabled by default //(since 1.0)//. Subversion and Git must be explicitly enabled if you wish to use them. See TracRepositoryAdmin for more details.
     372
     373The components can be enabled by adding the following to the `[components]` section of your [TracIni#components-section trac.ini], or enabling the components in the "Plugins" admin panel.
     374
     375{{{#!ini
     376tracopt.versioncontrol.svn.* = enabled
     377}}}
     378
     379{{{#!ini
     380tracopt.versioncontrol.git.* = enabled
     381}}}
     382
     383After enabling the components, repositories can be configured through the "Repositories" admin panel or by editing [TracIni#repositories-section trac.ini].
     384
     385=== Automatic reference to the SVN changesets in Trac tickets
    296386
    297387You 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:
     
    300390
    301391This 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.
    302 {{{
     392{{{#!ini
    303393tracopt.ticket.commit_updater.* = enabled
    304394}}}
    305395For more information, see the documentation of the `CommitTicketUpdater` component in the "Plugins" admin panel.

     397=== Using Trac
    308398
    309399Once 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.

    311 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.
     401Keep 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.
