    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.

    1414== Dependencies
    1515=== Mandatory Dependencies
     16
    1617To install Trac, the following software packages must be installed:
    1718
    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
    22 
    23 You also need a database system and the corresponding python bindings. The database can be either SQLite, PostgreSQL or MySQL.
     19 * [https://www.python.org/ Python], version >= 3.5
     20 * [https://pypi.org/project/setuptools setuptools], version > 5.6
     21 * [https://pypi.org/project/Jinja2 Jinja2], version >= 2.9.3
     22
     23You also need a database system and the corresponding Python bindings. The database can be either SQLite, PostgreSQL or MySQL.
    2424
    2525==== For the SQLite database #ForSQLite
    2626
    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 #9434 for more detail. See additional information in [trac:PySqlite PySqlite].
     27You already have the SQLite database bindings bundled with the standard distribution of Python (the `sqlite3` module).
     28
     29Optionally, 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.
    4130
    4231==== For the PostgreSQL database #ForPostgreSQL
    4332
    4433You 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
     34 * [https://www.postgresql.org/ PostgreSQL], version 9.1 or later
     35 * [https://pypi.org/project/psycopg2 psycopg2], version 2.5 or later
    4736
    4837See [trac:DatabaseBackend#Postgresql DatabaseBackend] for details.
     
    5039==== For the MySQL database #ForMySQL
    5140
    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
     41Trac works well with MySQL, provided you use the following:
     42
     43 * [https://mysql.com/ MySQL], version 5.0 or later
     44 * [https://pypi.org/project/PyMySQL PyMySQL]
    5645
    5746Given the caveats and known issues surrounding MySQL, read carefully the [trac:MySqlDb] page before creating the database.
     
    5948=== Optional Dependencies
    6049
    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].
     50==== Subversion
     51
     52[https://subversion.apache.org/ Subversion], 1.14.x or later and the '''corresponding''' Python bindings.
     53
     54There are [https://subversion.apache.org/packages.html pre-compiled SWIG bindings] available for various platforms. See [trac:TracSubversion#GettingSubversion getting Subversion] for more information.
     55
     56{{{#!div style="border: 1pt dotted; margin: 1em"
     57**Note:**
     58* Trac '''doesn't''' use [https://pypi.org/project/PySVN PySVN], nor does it work yet with the newer `ctype`-style bindings.
     59* If using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are [trac:ticket:493 not supported].
     60}}}
     61
     62For troubleshooting information, see the [trac:TracSubversion#Troubleshooting TracSubversion] page.
     63
     64==== Git
     65
     66[https://git-scm.com/ Git] 1.5.6 or later is supported. More information is available on the [trac:TracGit] page.
     67
     68==== Other Version Control Systems
     69
     70Support for other version control systems is provided via third-party plugins. See [trac:PluginList#VersionControlSystems] and [trac:VersionControlSystem].
    7571
    7672==== Web Server
     73
    7774A web server is optional because Trac is shipped with a server included, see the [#RunningtheStandaloneServer Running the Standalone Server] section below.
    7875
    7976Alternatively 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
    86    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    
     77 * [https://httpd.apache.org/ Apache] with
     78   - [https://github.com/GrahamDumpleton/mod_wsgi mod_wsgi], see [wiki:TracModWSGI] and
     79     [https://code.google.com/p/modwsgi/wiki/IntegrationWithTrac ModWSGI IntegrationWithTrac].
     80   - [http://modpython.org/ mod_python 3.5.0], see TracModPython
     81 * a [https://fastcgi-archives.github.io FastCGI]-capable web server (see TracFastCgi)
     82 * an [https://tomcat.apache.org/connectors-doc/ajp/ajpv13a.html AJP]-capable web server (see [trac:TracOnWindowsIisAjp TracOnWindowsIisAjp])
     83 * Microsoft IIS with FastCGI and a FastCGI-to-WSGI gateway (see [trac:CookBook/Installation/TracOnWindowsIisWfastcgi IIS with FastCGI])
     84 * a CGI-capable web server (see TracCgi), '''but usage of Trac as a cgi script is highly discouraged''', better use one of the previous options.
    9085
    9186==== Other Python Packages
    9287
    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
    96    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!
     88 * [http://babel.pocoo.org Babel], version >= 2.2, needed for localization support
     89 * [http://pytz.sourceforge.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. Installing Babel will install pytz.
     90 * [http://docutils.sourceforge.net docutils], version >= 0.14, for WikiRestructuredText.
     91 * [http://pygments.org Pygments], version >= 1.0, for [TracSyntaxColoring syntax highlighting].
     92 * [https://pypi.org/project/textile Textile], version >= 2.3, for rendering the [https://github.com/textile/python-textile Textile markup language].
     93 * [https://pypi.org/project/passlib passlib] on Windows to decode [TracStandalone#BasicAuthorization:Usingahtpasswdpasswordfile htpasswd formats] other than `SHA-1`.
     94 * [https://pypi.org/project/pyreadline pyreadline] on Windows for trac-admin [TracAdmin#InteractiveMode command completion].

    110102== 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 }}}
     103
     104The [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.
     105
     106It 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.
    130107
    131108=== 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.
     109
     110`pip` is the modern Python package manager and is included in Python distributions. `pip` will automatically resolve the //required// dependencies (Jinja2 and setuptools) and download the latest packages from pypi.org.
     111
     112You 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:
     113
     114{{{#!sh
     115$ pip install .
     116}}}
     117
     118`pip` supports numerous other install mechanisms. It can be passed the URL of an archive or other download location. Here are some examples:
     119
     120* Install the latest development version from a tar archive:
     121{{{#!sh
     122$ pip install https://download.edgewall.org/trac/Trac-latest-dev.tar.gz
     123}}}
     124* Install the unreleased 1.4-stable from subversion:
     125{{{#!sh
     126$ pip install svn+https://svn.edgewall.org/repos/trac/branches/1.4-stable
     127}}}
     128* Install the latest development preview (//not recommended for production installs//):
     129{{{#!sh
     130$ pip install --find-links=https://trac.edgewall.org/wiki/TracDownload Trac
     131}}}
     132
     133The optional dependencies can be installed from PyPI using `pip`:
     134{{{#!sh
     135$ pip install babel docutils pygments textile
     136}}}
     137
     138The optional dependencies can alternatively be
     139specified using the `extras` keys in the setup file:
     140{{{#!sh
     141$ pip install Trac[babel,rest,pygments,textile]
     142}}}
     143
     144`rest` is the extra that installs the `docutils`
     145dependency.
     146
     147Include `mysql` or `psycopg2-binary` in the
     148list if using the MySQL or PostgreSQL database.
     149
     150Additionally, 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.
     151
     152=== Using installer
     153
     154On 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.
     155
     156=== Using package manager
     157
     158Trac may be available in your platform's package repository. However, your package manager may not provide the latest release of Trac.
    195159
    196160== Creating a Project Environment
    197161
    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.
    199 
    200 A new environment is created using [wiki:TracAdmin trac-admin]:

    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 [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.

    216175Finally, 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:
    217176{{{#!sh
    218 $ chown -R apache.apache /path/to/myproject
     177$ chown -R apache:apache /path/to/myproject

    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 
    244 To 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`.

    252 }}}
    253 }}}
    254 
    255200=== Running Trac on a Web Server
    256201
    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.
     202Trac provides various options for connecting to a "real" web server:

    264209
    265210==== Generating the Trac cgi-bin directory #cgi-bin
    266211
    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.
     212Application scripts for CGI, FastCGI and mod-wsgi can be generated using the [TracAdmin trac-admin] `deploy` command:
     213[[TracAdminHelp(deploy)]]
     214
     215Grant the web server execution right on scripts in the `cgi-bin` directory.
     216
     217For example, the following yields a typical directory structure:
     218{{{#!sh
     219$ mkdir -p /var/trac
     220$ trac-admin /var/trac/<project> initenv
     221$ trac-admin /var/trac/<project> deploy /var/www
     222$ ls /var/www
     223cgi-bin htdocs
     224$ chmod ugo+x /var/www/cgi-bin/*
     225}}}
    277226
    278227==== Mapping Static Resources
    279228
    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:
     229Without 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.
     230
     231Web 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.
     232
     233There 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.
     234
     235A 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 `$env/htdocs` directory. This is probably appropriate for most installations but may not be what you want if, for example, you wish to upload plugins through the //Plugins// administration page.
     236
     237The `deploy` command creates an `htdocs` directory with:
     238 - `common/` - the static resources of Trac
     239 - `site/` - a copy of the environment's `htdocs/` directory
     240 - `shared` - the static resources shared by multiple Trac environments, with a location defined by the `[inherit]` `htdocs_dir` option
     241 - `<plugin>/` - one directory for each resource directory provided by the plugins enabled for this environment
     242
     243The example that follows will create a single `/chrome` alias. If that isn't the correct approach for your installation you simply need to create more specific aliases:
    302244{{{#!apache
    303245Alias /trac/chrome/common /path/to/trac/htdocs/common
    304246Alias /trac/chrome/site /path/to/trac/htdocs/site
    305 
    306 <Directory "/path/to/www/trac/htdocs">
    307   Order allow,deny
    308   Allow from all
     247Alias /trac/chrome/shared /path/to/trac/htdocs/shared
     248Alias /trac/chrome/<plugin> /path/to/trac/htdocs/<plugin>
     249}}}
     250
     251===== Example: Apache and `ScriptAlias` #ScriptAlias-example
     252
     253Assuming the deployment has been done this way:
     254{{{#!sh
     255$ trac-admin /var/trac/<project> deploy /var/www/trac
     256}}}
     257
     258Add 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:
     259{{{#!apache
     260Alias /trac/chrome /var/www/trac/htdocs
     261
     262<Directory "/var/www/trac/htdocs">
     263  # For Apache 2.2
     264  <IfModule !mod_authz_core.c>
     265    Order allow,deny
     266    Allow from all
     267  </IfModule>
     268  # For Apache 2.4
     269  <IfModule mod_authz_core.c>
     270    Require all granted
     271  </IfModule>
    309272</Directory>
    310273}}}
    311274
    312 If using mod_python, you might want to add this too (otherwise, the alias will be ignored):
     275If using mod_python, add this too, otherwise the alias will be ignored:
    313276{{{#!apache
    314 <Location "/trac/chrome/common/">
     277<Location "/trac/chrome/common">
    315278  SetHandler None
    316279</Location>
    317280}}}
    318281
    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):
     282Alternatively, 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:
    322283{{{#!apache
    323284Alias /trac/chrome/site /path/to/projectenv/htdocs
    324285
    325286<Directory "/path/to/projectenv/htdocs">
    326   Order allow,deny
    327   Allow from all
     287  # For Apache 2.2
     288  <IfModule !mod_authz_core.c>
     289    Order allow,deny
     290    Allow from all
     291  </IfModule>
     292  # For Apache 2.4
     293  <IfModule mod_authz_core.c>
     294    Require all granted
     295  </IfModule>
    328296</Directory>
    329297}}}
    330298
    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:
     299Another 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:
    332300{{{#!ini
    333301[trac]
    334302htdocs_location = http://static.example.org/trac-common/
    335303}}}
    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]).
     304
     305Note that this makes it easy to have a dedicated domain serve those static resources, preferentially cookie-less.
    337306
    338307Of 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:
     
    347316== Configuring Authentication
    348317
    349 Trac 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 
    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
     334
     335This user will have an //Admin// navigation item that directs to pages for administering your Trac project.
     336
     337== Configuring Trac
     338
     339Configuration options are documented on the TracIni page.
     340
     341TracRepositoryAdmin provides information on configuring version control repositories for your project.
     342
     343In addition to the optional version control backends, Trac provides several optional features that are disabled by default:
     344* [TracFineGrainedPermissions#AuthzPolicy Fine-grained permission policy]
     345* [TracPermissions#CreatingNewPrivileges Custom permissions]
     346* [TracTickets#deleter Ticket deletion]
     347* [TracTickets#cloner Ticket cloning]
     348* [TracRepositoryAdmin#CommitTicketUpdater Ticket changeset references]
     349
     350== Using Trac
    398351
    399352Once 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.
    400353
    401 Keep 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.
