    4 Trac 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 
    6 Since 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.
    7 
    8 If 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].

    10 What follows are generic instructions for installing and setting up Trac. While you may find instructions for installing Trac on specific systems at [trac:TracInstallPlatforms TracInstallPlatforms] on the main Trac site, please '''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, [https://sqlite.org/ SQLite], [https://www.postgresql.org/ PostgreSQL], or [https://mysql.com/ MySQL]. For HTML rendering, Trac uses the [http://jinja.pocoo.org Jinja2] templating system, though Genshi templates are supported until Trac 1.5.1.

    1616To install Trac, the following software packages must be installed:
    1717
    18  * [http://www.python.org/ Python], version >= 2.5 and < 3.0
    19    (note that we dropped the support for Python 2.4 in this release)
    20  * [http://peak.telecommunity.com/DevCenter/setuptools setuptools], version >= 0.6
    21  * [http://genshi.edgewall.org/wiki/Download Genshi], version >= 0.6
     18 * [https://www.python.org/ Python], version >= 2.7 and < 3.0
     19   (note that we dropped the support for Python 2.6 in this release)
     20 * [https://pypi.org/project/setuptools setuptools], version >= 0.6
     21 * [https://pypi.org/project/Jinja2 Jinja2], version >= 2.9.3
     22
     23{{{#!div style="border: 1pt dotted; margin: 1em"
     24**Setuptools Warning:** If the version of your setuptools is in the range 5.4 through 5.6, the environment variable `PKG_RESOURCES_CACHE_ZIP_MANIFESTS` must be set in order to avoid significant performance degradation. More information may be found in [#DeployingTrac Deploying Trac].
     25}}}
    2226
    2327You also need a database system and the corresponding python bindings. The database can be either SQLite, PostgreSQL or MySQL.
     
    2529==== For the SQLite database #ForSQLite
    2630
    27 As you must be using Python 2.5, 2.6 or 2.7, you already have the SQLite database bindings bundled with the standard distribution of Python: the `sqlite3` module.
    28 
    29 However, 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
    31 installers or the `tar.gz` archive for building from source:
    32 {{{#!sh
    33 $ tar xvfz <version>.tar.gz
    34 $ cd <version>
    35 $ python setup.py build_static install
    36 }}}
    37  
    38 This will download the latest SQLite code and build the bindings. SQLite 2.x is no longer supported.
    39 
    40 A 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 [trac:#9434] for more detail. See additional information in [trac:PySqlite PySqlite].
     31You already have the SQLite database bindings bundled with the standard distribution of Python (the `sqlite3` module).
     32
     33Optionally, you may install a newer version of [https://pypi.org/project/pysqlite pysqlite] than the one provided by the Python distribution. See [trac:PySqlite#ThePysqlite2bindings PySqlite] for details.
    4134
    4235==== For the PostgreSQL database #ForPostgreSQL
    4336
    4437You need to install the database and its Python bindings:
    45  * [http://www.postgresql.org/ PostgreSQL], version 8.0 or later
    46  * [http://pypi.python.org/pypi/psycopg2 psycopg2], version 2.0 or later
     38 * [https://www.postgresql.org/ PostgreSQL], version 9.1 or later
     39 * [https://pypi.org/project/psycopg2 psycopg2], version 2.0 or later
    4740
    4841See [trac:DatabaseBackend#Postgresql DatabaseBackend] for details.
     
    5043==== For the MySQL database #ForMySQL
    5144
    52 Trac works well with MySQL, provided you follow the guidelines:
    53 
    54  * [http://mysql.com/ MySQL], version 5.0 or later
    55  * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.2 or later
     45Trac works well with MySQL, provided you use the following:
     46
     47 * [https://mysql.com/ MySQL], version 5.0 or later
     48 * [https://pypi.org/project/PyMySQL PyMySQL]
    5649
    5750Given the caveats and known issues surrounding MySQL, read carefully the [trac:MySqlDb] page before creating the database.
     
    5952=== Optional Dependencies
    6053
    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.
    65 
    66 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. [trac:TracSubversion] points you to [http://alagazam.net Alagazam], which works for me under Python 2.6.)
    67 
    68 Note that Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], neither does it work yet with the newer `ctype`-style bindings.
    69 
    70 '''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently [trac:ticket:493 not supported].
    71 
    72 ===== Others
    73 
    74 Support for other version control systems is provided via third-parties. See [trac:PluginList] and [trac:VersionControlSystem].
     54==== Subversion
     55
     56[https://subversion.apache.org/ Subversion], 1.6.x or later and the '''''corresponding''''' Python bindings.
     57
     58There are [https://subversion.apache.org/packages.html pre-compiled SWIG bindings] available for various platforms. See [trac:TracSubversion#GettingSubversion getting Subversion] for more information.
     59
     60{{{#!div style="border: 1pt dotted; margin: 1em"
     61**Note:**
     62* Trac '''doesn't''' use [http://pysvn.tigris.org/ PySVN], nor does it work yet with the newer `ctype`-style bindings.
     63* If using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are [trac:ticket:493 not supported].

     66For troubleshooting information, see the [trac:TracSubversion#Troubleshooting TracSubversion] page.
     67
     68==== Git
     69
     70[https://git-scm.com/ Git] 1.5.6 or later is supported. More information is available on the [trac:TracGit] page.
     71
     72==== Other Version Control Systems
     73
     74Support for other version control systems is provided via third-party plugins. See [trac:PluginList#VersionControlSystems] and [trac:VersionControlSystem].
    7575
    7676==== Web Server
     
    7878
    7979Alternatively you can configure Trac to run in any of the following environments:
    80  * [http://httpd.apache.org/ Apache] with
    81    - [http://code.google.com/p/modwsgi/ mod_wsgi], see [wiki:TracModWSGI] and
    82      http://code.google.com/p/modwsgi/wiki/IntegrationWithTrac
    83    - [http://modpython.org/ mod_python >= 3.3.1], (deprecated: see TracModPython)
    84  * a [http://www.fastcgi.com/ FastCGI]-capable web server (see TracFastCgi)
    85  * an [http://tomcat.apache.org/connectors-doc/ajp/ajpv13a.html AJP]-capable web
     80 * [https://httpd.apache.org/ Apache] with
     81   - [https://github.com/GrahamDumpleton/mod_wsgi mod_wsgi], see [wiki:TracModWSGI] and
     82     [https://code.google.com/p/modwsgi/wiki/IntegrationWithTrac ModWSGI IntegrationWithTrac].
     83   - [http://modpython.org/ mod_python 3.5.0], see TracModPython
     84 * a [https://fastcgi-archives.github.io FastCGI]-capable web server (see TracFastCgi)
     85 * an [https://tomcat.apache.org/connectors-doc/ajp/ajpv13a.html AJP]-capable web
    8686   server (see [trac:TracOnWindowsIisAjp TracOnWindowsIisAjp])
    87  * a CGI-capable web server (see TracCgi), '''but usage of Trac as a cgi script
    88    is highly discouraged''', better use one of the previous options.
    89    
     87 * Microsoft IIS with FastCGI and a FastCGI-to-WSGI gateway (see [trac:CookBook/Installation/TracOnWindowsIisWfastcgi IIS with FastCGI])
     88 * a CGI-capable web server (see TracCgi), '''but usage of Trac as a cgi script
     89   is highly discouraged''', better use one of the previous options.
     90
    9091
    9192==== Other Python Packages
    9293
    93  * [http://babel.edgewall.org Babel], version >= 0.9.5,
    94    needed for localization support (unreleased version 1.0dev should work as well)
    95  * [http://docutils.sourceforge.net/ docutils], version >= 0.3.9
     94 * [http://babel.pocoo.org Babel], version 0.9.6 or >= 1.3,
     95   needed for localization support
     96 * [http://pytz.sourceforge.net pytz] to get a complete list of time zones,
     97   otherwise Trac will fall back on a shorter list from
     98   an internal time zone implementation. Installing Babel
     99   will install pytz.
     100 * [http://docutils.sourceforge.net docutils], version >= 0.3.9
    96101   for WikiRestructuredText.
    97  * [http://pygments.org Pygments] for
    98    [wiki:TracSyntaxColoring syntax highlighting].
    99    [http://silvercity.sourceforge.net/ SilverCity] and/or
    100    [http://gnu.org/software/enscript/enscript.html Enscript] may still be used
    101    but are deprecated and you really should be using Pygments.
    102  * [http://pytz.sf.net pytz] to get a complete list of time zones,
    103    otherwise Trac will fall back on a shorter list from
    104    an internal time zone implementation.
    105 
    106 '''Attention''': The available versions of these dependencies are not necessarily interchangeable, so please pay attention to the version numbers. 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].
    107 
    108 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!
     102 * [http://pygments.org Pygments] for
     103   [TracSyntaxColoring syntax highlighting].
     104 * [https://pypi.org/project/textile Textile] for rendering the [https://github.com/textile/python-textile Textile markup language].
     105 * [https://pypi.org/project/passlib passlib] on Windows to decode [TracStandalone#BasicAuthorization:Usingahtpasswdpasswordfile htpasswd formats] other than `SHA-1`.
     106 * [https://pypi.org/project/pyreadline pyreadline] on Windows for trac-admin [TracAdmin#InteractiveMode command completion].

    110114== Installing Trac
    111 === Using `easy_install`
    112 One way to install Trac is using [http://pypi.python.org/pypi/setuptools setuptools]. With setuptools you can install Trac from the Subversion repository.
    113 
    114 A few examples:
    115 
    116  - Install Trac 1.0:
    117    {{{#!sh
    118    easy_install Trac==1.0
    119    }}}
    120  - Install latest development version:
    121    {{{#!sh
    122    easy_install Trac==dev
    123    }}}
    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 }}}
     115
     116The [TracAdmin trac-admin] command-line tool, used to create and maintain [TracEnvironment project environments], as well as the [TracStandalone tracd] standalone server are installed along with Trac. There are several methods for installing Trac.
     117
     118It is assumed throughout this guide that you have elevated permissions as the `root` user or by prefixing commands with `sudo`. The umask `0002` should be used for a typical installation on a Unix-based platform.
    130119
    131120=== Using `pip`
    132 'pip' is an easy_install replacement that is very useful to quickly install python packages.
    133 To get a Trac installation up and running in less than 5 minutes:
    134 
    135 Assuming you want to have your entire pip installation in `/opt/user/trac`
    136 
    137  -
    138  {{{#!sh
    139 pip install trac psycopg2
    140 }}}
    141 or
    142  -
    143  {{{#!sh
    144 pip install trac mysql-python
    145 }}}
    146 
    147 Make sure your OS specific headers are available for pip to automatically build PostgreSQL (`libpq-dev`) or MySQL (`libmysqlclient-dev`) bindings.
    148 
    149 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`.
    150 
    151 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)
    152 
    153 Additionally, 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
    156 Of 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.
    157 
    158 {{{#!sh
    159 $ python ./setup.py install
    160 }}}
    161 
    162 ''You will need root permissions or equivalent for this step.''
    163 
    164 This will byte-compile the Python source code and install it as an .egg file or folder in the `site-packages` directory
    165 of your Python installation. The .egg will also contain all other resources needed by standard Trac, such as `htdocs` and `templates`.
    166 
    167 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.
    168 
    169 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):
    170 {{{#!sh
    171 $ python ./setup.py install
    172 }}}
    173 Alternatively, you can run `bdist_egg` and copy the .egg from `dist/` to the place of your choice, or you can create a Windows installer (`bdist_wininst`).
    174 
    175 === Advanced Options
    176 
    177 To install Trac to a custom location, or find out about other advanced installation options, run:
    178 {{{#!sh
    179 easy_install --help
    180 }}}
    181 
    182 Also see [http://docs.python.org/2/install/index.html Installing Python Modules] for detailed information.
    183 
    184 Specifically, you might be interested in:
    185 {{{#!sh
    186 easy_install --prefix=/path/to/installdir
    187 }}}
    188 or, if installing Trac on a Mac OS X system:
    189 {{{#!sh
    190 easy_install --prefix=/usr/local --install-dir=/Library/Python/2.5/site-packages
    191 }}}
    192 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.
    193 
    194 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.
     121`pip` is the modern Python package manager and is included in Python 2.7.9 and later. Use [https://bootstrap.pypa.io/get-pip.py get-pip.py] to install `pip` for an earlier version of Python.
     122
     123{{{#!sh
     124$ pip install Trac
     125}}}
     126
     127`pip` will automatically resolve the //required// dependencies (Jinja2 and setuptools) and download the latest packages from pypi.org.
     128
     129You can also install directly from a source package. You can obtain the source in a tar or zip from the [trac:TracDownload] page. After extracting the archive, change to the directory containing `setup.py` and run:
     130
     131{{{#!sh
     132$ pip install .
     133}}}
     134
     135`pip` supports numerous other install mechanisms. It can be passed the URL of an archive or other download location. Here are some examples:
     136
     137* Install the latest stable version from a zip archive:
     138{{{#!sh
     139$ pip install https://download.edgewall.org/trac/Trac-latest.zip
     140}}}
     141* Install the latest development version from a tar archive:
     142{{{#!sh
     143$ pip install https://download.edgewall.org/trac/Trac-latest-dev.tar.gz
     144}}}
     145* Install the unreleased 1.2-stable from subversion:
     146{{{#!sh
     147$ pip install svn+https://svn.edgewall.org/repos/trac/branches/1.2-stable
     148}}}
     149* Install the latest development preview (//not recommended for production installs//):
     150{{{#!sh
     151$ pip install --find-links=https://trac.edgewall.org/wiki/TracDownload Trac
     152}}}
     153
     154The optional dependencies can be installed from PyPI using `pip`:
     155{{{#!sh
     156$ pip install babel docutils pygments textile
     157}}}
     158
     159The optional dependencies can alternatively be
     160specified using the `extras` keys in the setup file:
     161{{{#!sh
     162$ pip install Trac[babel,rest,pygments,textile]
     163}}}
     164
     165`rest` is the extra that installs the `docutils`
     166dependency.
     167
     168Include `mysql` or `psycopg2-binary` in the
     169list if using the MySQL or PostgreSQL database.
     170
     171Additionally, you can install several Trac plugins from PyPI (listed [https://pypi.org/search/?c=Framework+%3A%3A+Trac here]) using pip. See TracPlugins for more information.
     172
     173=== Using installer
     174
     175On Windows, Trac can be installed using the exe installers available on the [trac:TracDownload] page. Installers are available for the 32-bit and 64-bit versions of Python. Make sure to use the installer that matches the architecture of your Python installation.
     176
     177=== Using package manager
     178
     179Trac may be available in your platform's package repository. However, your package manager may not provide the latest release of Trac.

    198 A [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.

     184
     185A new environment is created using [TracAdmin trac-admin]:
    201186{{{#!sh
    202187$ trac-admin /path/to/myproject initenv
    203188}}}
    204189
    205 [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.
    206 
    207 Using the default database connection string in particular will always work as long as you have SQLite installed.
    208 For the other [trac:DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
    209 
    210 Since 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.
    211 
    212 Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file.
    213 
    214 When selecting the location of your environment, make sure that the filesystem on which the environment directory resides supports sub-second timestamps (i.e. **not** `ext2` or `ext3` on Linux), 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.
     190[TracAdmin trac-admin] will prompt you for the information it needs to create the environment: the name of the project and the [TracEnvironment#DatabaseConnectionStrings database connection string]. If you're not sure what to specify for any of these options, just press `<Enter>` to use the default value.
     191
     192Using the default database connection string will always work as long as you have SQLite installed. For the other [trac:DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
     193
     194Also note that the values you specify here can be changed later using TracAdmin or directly editing the [TracIni conf/trac.ini] configuration file.
    215195
    216196Finally, 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:
    217197{{{#!sh
    218 $ chown -R apache.apache /path/to/myproject
     198$ chown -R apache:apache /path/to/myproject

     211
     212If running `tracd`, the environment variable can be set system-wide or for just the user that runs the `tracd` process. There are several ways to accomplish this in addition to what is discussed here, and depending on the distribution of your OS.
     213

    254 
    255239=== Running Trac on a Web Server
    256240
    257 Trac 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 
    263 Trac 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.
     241Trac provides various options for connecting to a "real" web server:
     242 - [TracFastCgi FastCGI]
     243 - [wiki:TracModWSGI Apache with mod_wsgi]
     244 - [TracModPython Apache with mod_python]
     245 - [TracCgi CGI] //(should not be used, as the performance is far from optimal)//
     246
     247Trac 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], [https://uwsgi-docs.readthedocs.io/en/latest/#Traconapacheinasub-uri uwsgi], [trac:TracOnWindowsIisIsapi Isapi-wsgi] etc.
    264248
    265249==== Generating the Trac cgi-bin directory #cgi-bin
    266250
    267 In order for Trac to function properly with FastCGI you need to have a `trac.fcgi` file and for mod_wsgi a `trac.wsgi` file. These are Python scripts which load the appropriate Python code. They can be generated using the `deploy` option of [wiki:TracAdmin trac-admin].
    268 
    269 There is, however, a bit of a chicken-and-egg problem. The [wiki:TracAdmin trac-admin] command requires an existing environment to function, but complains if the deploy directory already exists. This is a problem, because environments are often stored in a subdirectory of the deploy. The solution is to do something like this:
    270 {{{#!sh
    271 mkdir -p /usr/share/trac/projects/my-project
    272 trac-admin /usr/share/trac/projects/my-project initenv
    273 trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy
    274 mv /tmp/deploy/* /usr/share/trac
    275 }}}
    276 Don't forget to check that the web server has the execution right on scripts in the `/usr/share/trac/cgi-bin` directory.
     251Application scripts for CGI, FastCGI and mod-wsgi can be generated using the [TracAdmin trac-admin] `deploy` command:
     252[[TracAdminHelp(deploy)]]
     253
     254Grant the web server execution right on scripts in the `cgi-bin` directory.
     255
     256For example, the following yields a typical directory structure:
     257{{{#!sh
     258$ mkdir -p /var/trac
     259$ trac-admin /var/trac/<project> initenv
     260$ trac-admin /var/trac/<project> deploy /var/www
     261$ ls /var/www
     262cgi-bin htdocs
     263$ chmod ugo+x /var/www/cgi-bin/*
     264}}}
    277265
    278266==== Mapping Static Resources
    279267
    280 Out of the box, Trac will pass static resources such as style sheets or images through itself. For anything but a tracd only based deployment, this is far from optimal as the web server could be set up to directly serve those static resources (for CGI setup, this is '''highly undesirable''' and will cause abysmal performance).
    281 
    282 Web servers such as [http://httpd.apache.org/ Apache] allow you to create “Aliases” to resources, giving them a virtual URL that doesn't necessarily reflect the layout of the servers file system. We also can map requests for static resources directly to the directory on the file system, avoiding processing these requests by Trac itself.
    283 
    284 There are two primary URL paths for static resources - `/chrome/common` and `/chrome/site`. Plugins can add their own resources, usually accessible by `/chrome/<plugin>` path, so its important to override only known paths and not try to make universal `/chrome` alias for everything.
    285 
    286 Note that in order to get those static resources on the filesystem, you need first to extract the relevant resources from Trac using the [TracAdmin trac-admin]` <environment> deploy` command:
    287 [[TracAdminHelp(deploy)]]
    288 
    289 The 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 
    296 Assuming the deployment has been done this way:
    297 {{{#!sh
    298 $ trac-admin /var/trac/env deploy /path/to/shared/trac
    299 }}}
    300 
    301 Add the following snippet to Apache configuration ''before'' the `ScriptAlias` or `WSGIScriptAlias` (which map all the other requests to the Trac application), changing paths to match your deployment:
     268Without additional configuration, Trac will handle requests for static resources such as stylesheets and images. For anything other than a TracStandalone deployment, this is not optimal as the web server can be set up to directly serve the static resources. For CGI setup, this is '''highly undesirable''' as it causes abysmal performance.
     269
     270Web servers such as [https://httpd.apache.org/ Apache] allow you to create //Aliases// to resources, giving them a virtual URL that doesn't necessarily reflect their location on the file system. We can map requests for static resources directly to directories on the file system, to avoid Trac processing the requests.
     271
     272There are two primary URL paths for static resources: `/chrome/common` and `/chrome/site`. Plugins can add their own resources, usually accessible at the `/chrome/<plugin>` path.
     273
     274A single `/chrome` alias can used if the static resources are extracted for all plugins. This means that the `deploy` command (discussed in the previous section) must be executed after installing or updating a plugin that provides static resources, or after modifying resources in the `$env/htdocs` directory. This is probably appropriate for most installations but may not be what you want if, for example, you wish to upload plugins through the //Plugins// administration page.
     275
     276The `deploy` command creates an `htdocs` directory with:
     277 - `common/` - the static resources of Trac
     278 - `site/` - a copy of the environment's `htdocs/` directory
     279 - `shared` - the static resources shared by multiple Trac environments, with a location defined by the `[inherit]` `htdocs_dir` option
     280 - `<plugin>/` - one directory for each resource directory provided by the plugins enabled for this environment
     281
     282The example that follows will create a single `/chrome` alias. If that isn't the correct approach for your installation you simply need to create more specific aliases:
    302283{{{#!apache
    303284Alias /trac/chrome/common /path/to/trac/htdocs/common
    304285Alias /trac/chrome/site /path/to/trac/htdocs/site
     286Alias /trac/chrome/shared /path/to/trac/htdocs/shared
     287Alias /trac/chrome/<plugin> /path/to/trac/htdocs/<plugin>
     288}}}
     289
     290===== Example: Apache and `ScriptAlias` #ScriptAlias-example
     291
     292Assuming the deployment has been done this way:
     293{{{#!sh
     294$ trac-admin /var/trac/<project> deploy /var/www
     295}}}
     296
     297Add the following snippet to Apache configuration, changing paths to match your deployment. The snippet must be placed ''before'' the `ScriptAlias` or `WSGIScriptAlias` directive, because those directives map all requests to the Trac application:
     298{{{#!apache
     299Alias /trac/chrome /path/to/trac/htdocs
    305300
    306301<Directory "/path/to/www/trac/htdocs">
    307   Order allow,deny
    308   Allow from all
     302  # For Apache 2.2
     303  <IfModule !mod_authz_core.c>
     304    Order allow,deny
     305    Allow from all
     306  </IfModule>
     307  # For Apache 2.4
     308  <IfModule mod_authz_core.c>
     309    Require all granted
     310  </IfModule>
    309311</Directory>
    310312}}}
    311313
    312 If using mod_python, you might want to add this too (otherwise, the alias will be ignored):
     314If using mod_python, add this too, otherwise the alias will be ignored:
    313315{{{#!apache
    314 <Location "/trac/chrome/common/">
     316<Location "/trac/chrome/common">
    315317  SetHandler None
    316318</Location>
    317319}}}
    318320
    319 Note that we mapped `/trac` part of the URL to the `trac.*cgi` script, and the path `/trac/chrome/common` is the path you have to append to that location to intercept requests to the static resources.
    320 
    321 Similarly, if you have static resources in a project's `htdocs` directory (which is referenced by `/trac/chrome/site` URL in themes), you can configure Apache to serve those resources (again, put this ''before'' the `ScriptAlias` or `WSGIScriptAlias` for the .*cgi scripts, and adjust names and locations to match your installation):
     321Alternatively, if you wish to serve static resources directly from your project's `htdocs` directory rather than the location to which the files are extracted with the `deploy` command, you can configure Apache to serve those resources. Again, put this ''before'' the `ScriptAlias` or `WSGIScriptAlias` for the .*cgi scripts, and adjust names and locations to match your installation:
    322322{{{#!apache
    323323Alias /trac/chrome/site /path/to/projectenv/htdocs
    324324
    325325<Directory "/path/to/projectenv/htdocs">
    326   Order allow,deny
    327   Allow from all
     326  # For Apache 2.2
     327  <IfModule !mod_authz_core.c>
     328    Order allow,deny
     329    Allow from all
     330  </IfModule>
     331  # For Apache 2.4
     332  <IfModule mod_authz_core.c>
     333    Require all granted
     334  </IfModule>
    328335</Directory>
    329336}}}
    330337
    331 Alternatively to aliasing `/trac/chrome/common`, you can tell Trac to generate direct links for those static resources (and only those), using the [[wiki:TracIni#trac-section| [trac] htdocs_location]] configuration setting:
     338Another alternative to aliasing `/trac/chrome/common` is having Trac generate direct links for those static resources (and only those), using the [TracIni#trac-htdocs_location-option trac.htdocs_location] configuration setting:
    332339{{{#!ini
    333340[trac]
    334341htdocs_location = http://static.example.org/trac-common/
    335342}}}
    336 Note that this makes it easy to have a dedicated domain serve those static resources (preferentially [http://code.google.com/speed/page-speed/docs/request.html#ServeFromCookielessDomain cookie-less]).
     343
     344Note that this makes it easy to have a dedicated domain serve those static resources, preferentially cookie-less.
    337345
    338346Of 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:
     
    349357Trac 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.
    350358
    351 The process of adding, removing, and configuring user accounts for authentication depends on the specific way you run Trac.

    367 == Finishing the install
    368 
    369 === Enable version control components
    370 
    371 Support 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 
    373 The 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
    376 tracopt.versioncontrol.svn.* = enabled
    377 }}}
    378 
    379 {{{#!ini
    380 tracopt.versioncontrol.git.* = enabled
    381 }}}
    382 
    383 After 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
    386 
    387 You can configure SVN to automatically add a reference to the changeset into the ticket comments, whenever changes are committed to the repository. The description of the commit needs to contain one of the following formulas:
    388  * '''`Refs #123`''' - to reference this changeset in `#123` ticket
    389  * '''`Fixes #123`''' - to reference this changeset and close `#123` ticket with the default status ''fixed''
    390 
    391 This functionality requires a post-commit hook to be installed as described in [wiki:TracRepositoryAdmin#ExplicitSync TracRepositoryAdmin], and enabling the optional commit updater components by adding the following line to the `[components]` section of your [wiki:TracIni#components-section trac.ini], or enabling the components in the "Plugins" admin panel.
    392 {{{#!ini
    393 tracopt.ticket.commit_updater.* = enabled
    394 }}}
    395 For more information, see the documentation of the `CommitTicketUpdater` component in the "Plugins" admin panel.
    396 
    397 === Using Trac
     373
     374This user will have an //Admin// navigation item that directs to pages for administering your Trac project.

     376== Configuring Trac
     377
     378Configuration options are documented on the TracIni page.
     379
     380TracRepositoryAdmin provides information on configuring version control repositories for your project.
     381
     382In addition to the optional version control backends, Trac provides several optional features that are disabled by default:
     383* [TracFineGrainedPermissions#AuthzPolicy Fine-grained permission policy]
     384* [TracPermissions#CreatingNewPrivileges Custom permissions]
     385* [TracTickets#deleter Ticket deletion]
