    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's probably a translation available for your language. If you want to be able to use the Trac interface in other languages, then make sure you **first** have installed the optional package [#OtherPythonPackages Babel]. Lacking Babel, you will only get the default english version, as usual. If you install Babel later on, you will need to re-install Trac.
    7 
    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 and its requirements. While you may find instructions for installing Trac on specific systems at TracInstallPlatforms on the main Trac site, please be sure to '''first read through these general instructions''' to get a good understanding of the tasks involved.
     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 will still be supported until at least Trac 1.5.1.

     6Trac 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.

    14 == Dependencies ==
     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)
    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.
    24 The database can be either SQLite, PostgreSQL or MySQL.
     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}}}
     26
     27You also need a database system and the corresponding python bindings. The database can be either SQLite, PostgreSQL or MySQL.
    2528
    2629==== For the SQLite database #ForSQLite
    2730
    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 {{{
    33 $ tar xvfz <version>.tar.gz
    34 $ cd <version>
    35 $ python setup.py build_static install
    36 }}}
    37  
    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].
     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.
    5334
    5435==== For the PostgreSQL database #ForPostgreSQL
    5536
    5637You need to install the database and its Python bindings:
    57  * [http://www.postgresql.org/ PostgreSQL], version 8.0 or later
    58  * [http://pypi.python.org/pypi/psycopg2 psycopg2]
     38 * [https://www.postgresql.org/ PostgreSQL], version 9.1 or later
     39 * [https://pypi.org/project/psycopg2 psycopg2], version 2.0 or later
    5940
    6041See [trac:DatabaseBackend#Postgresql DatabaseBackend] for details.
    6142
    62 
    6343==== For the MySQL database #ForMySQL
    6444
    65 Trac can now work quite well with MySQL, provided you follow the guidelines.
    66 
    67  * [http://mysql.com/ MySQL], version 5.0 or later
    68  * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.2 or later
    69 
    70 It is '''very''' important to read carefully the [trac:MySqlDb] page before creating the database.
     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]
     49
     50Given the caveats and known issues surrounding MySQL, read carefully the [trac:MySqlDb] page before creating the database.
    7151
    7252=== Optional Dependencies
    7353
    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 
    83 
    84 '''Please note:''' if using Subversion, Trac must be installed on the '''same machine'''. Remote repositories are currently [trac:ticket:493 not supported].
    85 
    86 
    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.
    95  * [http://httpd.apache.org/ Apache] with
    96    - [http://code.google.com/p/modwsgi/ mod_wsgi], see [wiki:TracModWSGI] and
    97      http://code.google.com/p/modwsgi/wiki/IntegrationWithTrac
    98    - [http://modpython.org/ mod_python 3.3.1], deprecated: see TracModPython)
    99  * a [http://www.fastcgi.com/ FastCGI]-capable web server (see TracFastCgi)
    100  * an [http://tomcat.apache.org/connectors-doc/ajp/ajpv13a.html AJP]-capable web
    101    server (see [trac:TracOnWindowsIisAjp])
     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].
     75
     76==== Web Server
     77A web server is optional because Trac is shipped with a server included, see the [#RunningtheStandaloneServer Running the Standalone Server] section below.
     78
     79Alternatively you can configure Trac to run in any of the following environments:
     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
     86   server (see [trac:TracOnWindowsIisAjp TracOnWindowsIisAjp])
     87 * Microsoft IIS with FastCGI and a FastCGI-to-WSGI gateway (see [trac:CookBook/Installation/TracOnWindowsIisWfastcgi IIS with FastCGI])
    10288 * a CGI-capable web server (see TracCgi), '''but usage of Trac as a cgi script
    10389   is highly discouraged''', better use one of the previous options.
    10490   
    10591
    106 ==== Other Python Packages ====
    107 
    108  * [http://babel.edgewall.org Babel], version >= 0.9.5,
    109    needed for localization support[[BR]]
    110    ''Note: '' If you want to be able to use the Trac interface in other languages, then make sure you first have installed the optional package Babel. Lacking Babel, you will only get the default english version, as usual. If you install Babel later on, you will need to re-install Trac.
    111  * [http://docutils.sourceforge.net/ docutils], version >= 0.3.9
     92==== Other Python Packages
     93
     94 * [http://babel.pocoo.org Babel], version 0.9.6 or >= 1.3,
     95   needed for localization support
     96 * [http://docutils.sourceforge.net docutils], version >= 0.3.9
    11297   for WikiRestructuredText.
    113  * [http://pygments.pocoo.org Pygments] for
    114    [wiki:TracSyntaxColoring syntax highlighting].
    115    [http://silvercity.sourceforge.net/ SilverCity] and/or
    116    [http://gnu.org/software/enscript/enscript.html Enscript] may still be used
    117    but are deprecated and you really should be using Pygments.
    118  * [http://pytz.sf.net pytz] to get a complete list of time zones,
     98 * [http://pygments.org Pygments] for
     99   [TracSyntaxColoring syntax highlighting].
     100 * [https://pypi.org/project/textile Textile] for rendering the [https://github.com/textile/python-textile Textile markup language].
     101 * [http://pytz.sourceforge.net pytz] to get a complete list of time zones,
    119102   otherwise Trac will fall back on a shorter list from
    120103   an internal time zone implementation.
    121 
    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!).
    125 
    126 
    127 == Installing Trac ==
    128 === 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;
    131 
    132 A few examples:
    133 
    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
    138    }}}
    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
    144    }}}
    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.
     104 * [https://pypi.org/project/passlib passlib] on Windows to decode [TracStandalone#BasicAuthorization:Usingahtpasswdpasswordfile htpasswd formats] other than `SHA-1`.
     105 * [https://pypi.org/project/pyreadline pyreadline] on Windows for trac-admin [TracAdmin#InteractiveMode command completion].

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].
     109}}}
     110
     111Please 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''.
     112
     113== Installing Trac
     114
     115The [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.
     116
     117It 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.
    196118
    197119=== Using `pip`
    198 '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:
    200 
    201 Assuming you want to have your entire pip installation in /opt/user/trac:
    202 
    203  -
    204 {{{
    205 pip -E /opt/user/trac install trac psycopg2
    206 }}}
    207 or
    208  -
    209 {{{
    210 pip -E /opt/user/trac install trac mysql-python
    211 }}}
    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.
    226 
    227 A new environment is created using [wiki:TracAdmin trac-admin]:
    228 {{{
     120`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.
     121
     122{{{#!sh
     123$ pip install Trac
     124}}}
     125
     126`pip` will automatically resolve the //required// dependencies (Jinja2 and setuptools) and download the latest packages from pypi.org.
     127
     128You 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:
     129
     130{{{#!sh
     131$ pip install .
     132}}}
     133
     134`pip` supports numerous other install mechanisms. It can be passed the URL of an archive or other download location. Here are some examples:
     135
     136* Install the latest stable version from a zip archive:
     137{{{#!sh
     138$ pip install https://download.edgewall.org/trac/Trac-latest.zip
     139}}}
     140* Install the latest development version from a tar archive:
     141{{{#!sh

     152
     153The optional dependencies can be installed from PyPI using `pip`:
     154{{{#!sh
     155$ pip install babel docutils pygments pytz textile
     156}}}
     157
     158Additionally, 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.
     159
     160=== Using installer
     161
     162On 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.
     163
     164=== Using package manager
     165
     166Trac may be available in your platform's package repository. However, your package manager may not provide the latest release of Trac.
     167
     168== Creating a Project Environment
     169
     170A [TracEnvironment Trac environment] is the backend where Trac stores information like wiki pages, tickets, reports, settings, etc. An environment is a directory that contains a human-readable [TracIni configuration file], and other files and directories.
     171
     172A new environment is created using [TracAdmin trac-admin]:
     173{{{#!sh
    229174$ trac-admin /path/to/myproject initenv
    230175}}}
    231176
    232 [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.
    233 
    234 Using the default database connection string in particular will always work as long as you have SQLite installed.
    235 For the other [DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
    236 
    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.
    238 
    239 Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file.
     177[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.
     178
     179Using 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.
     180
     181Also note that the values you specify here can be changed later using TracAdmin or directly editing the [TracIni conf/trac.ini] configuration file.
    240182
    241183Finally, 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 }}}
     184{{{#!sh
     185$ chown -R apache:apache /path/to/myproject
     186}}}
     187
     188The 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).

    250 
    251 == Running the Standalone Server ==
    252 
    253 After having created a Trac environment, you can easily try the web interface by running the standalone server [wiki:TracStandalone tracd]:
    254 {{{
     194== Deploying Trac
     195
     196{{{#!div style="border: 1pt dotted; margin: 1em"
     197**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.
     198
     199If 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.
     200
     201To 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`.
     202{{{#!sh
     203export PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1
     204}}}
     205
     206Alternatively, the variable can be set in the shell before executing `tracd`:
     207{{{#!sh
     208$ PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1 tracd --port 8000 /path/to/myproject
     209}}}
     210
     211If running the Apache web server, !Ubuntu/Debian users should add the `export` statement to `/etc/apache2/envvars`. !RedHat/CentOS/Fedora should can add the `export` statement to `/etc/sysconfig/httpd`.
     212}}}
     213
     214=== Running the Standalone Server
     215
     216After having created a Trac environment, you can easily try the web interface by running the standalone server [TracStandalone tracd]:
     217{{{#!sh
    255218$ tracd --port 8000 /path/to/myproject
    256219}}}
    257220
    258 Then, fire up a browser and visit `http://localhost:8000/`. You should get a simple listing of all environments that `tracd` knows about. Follow the link to the environment you just created, and you should see Trac in action. If you only plan on managing a single project with Trac you can have the standalone server skip the environment list by starting it like this:
    259 {{{

    262225
    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 ====
    270 
    271 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].
    272 
    273 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:
    274 {{{
    275 mkdir -p /usr/share/trac/projects/my-project
    276 trac-admin /usr/share/trac/projects/my-project initenv
    277 trac-admin /usr/share/trac/projects/my-project deploy /tmp/deploy
    278 mv /tmp/deploy/* /usr/share/trac
    279 }}}
    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 ==
    296 
    297 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:
    298  * '''`Refs #123`''' - to reference this changeset in `#123` ticket
    299  * '''`Fixes #123`''' - to reference this changeset and close `#123` ticket with the default status ''fixed''
    300 
    301 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.
    302 {{{
    303 tracopt.ticket.commit_updater.* = enabled
    304 }}}
    305 For more information, see the documentation of the `CommitTicketUpdater` component in the "Plugins" admin panel.
    306 
    307 == Using Trac ==
     226=== Running Trac on a Web Server
     227
     228Trac provides various options for connecting to a "real" web server:
     229 - [TracFastCgi FastCGI]
     230 - [wiki:TracModWSGI Apache with mod_wsgi]
     231 - [TracModPython Apache with mod_python]
     232 - [TracCgi CGI] //(should not be used, as the performance is far from optimal)//
     233
     234Trac 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.
     235
     236==== Generating the Trac cgi-bin directory #cgi-bin
     237
     238Application scripts for CGI, FastCGI and mod-wsgi can be generated using the [TracAdmin trac-admin] `deploy` command:
     239[[TracAdminHelp(deploy)]]
     240
     241Grant the web server execution right on scripts in the `cgi-bin` directory.
     242
     243For example, the following yields a typical directory structure:
     244{{{#!sh
     245$ mkdir -p /var/trac
     246$ trac-admin /var/trac/<project> initenv
     247$ trac-admin /var/trac/<project> deploy /var/www
     248$ ls /var/www
     249cgi-bin htdocs
     250$ chmod ugo+x /var/www/cgi-bin/*
     251}}}
     252
     253==== Mapping Static Resources
     254
     255Without 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.
     256
     257Web 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.
     258
     259There 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.
     260
     261A 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 `$env/htdocs` directory. This is probably appropriate for most installations but may not be what you want if, for example, you wish to upload plugins through the //Plugins// administration page.
     262
     263The `deploy` command creates an `htdocs` directory with:
     264 - `common/` - the static resources of Trac
     265 - `site/` - a copy of the environment's `htdocs/` directory
     266 - `shared` - the static resources shared by multiple Trac environments, with a location defined by the `[inherit]` `htdocs_dir` option
     267 - `<plugin>/` - one directory for each resource directory provided by the plugins enabled for this environment
     268
     269The example that follows will create a single `/chrome` alias. If that isn't the correct approach for your installation you simply need to create more specific aliases:
     270{{{#!apache
     271Alias /trac/chrome/common /path/to/trac/htdocs/common
     272Alias /trac/chrome/site /path/to/trac/htdocs/site
     273Alias /trac/chrome/shared /path/to/trac/htdocs/shared
     274Alias /trac/chrome/<plugin> /path/to/trac/htdocs/<plugin>
     275}}}
     276
     277===== Example: Apache and `ScriptAlias` #ScriptAlias-example
     278
     279Assuming the deployment has been done this way:
     280{{{#!sh
     281$ trac-admin /var/trac/<project> deploy /var/www
     282}}}
     283
     284Add 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:
     285{{{#!apache
     286Alias /trac/chrome /path/to/trac/htdocs
     287
     288<Directory "/path/to/www/trac/htdocs">
     289  # For Apache 2.2
     290  <IfModule !mod_authz_core.c>
     291    Order allow,deny
     292    Allow from all
     293  </IfModule>
     294  # For Apache 2.4
     295  <IfModule mod_authz_core.c>
     296    Require all granted
     297  </IfModule>
     298</Directory>
     299}}}
     300
     301If using mod_python, add this too, otherwise the alias will be ignored:
     302{{{#!apache
     303<Location "/trac/chrome/common">
     304  SetHandler None
     305</Location>
     306}}}
     307
     308Alternatively, 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:
     309{{{#!apache
     310Alias /trac/chrome/site /path/to/projectenv/htdocs
     311
     312<Directory "/path/to/projectenv/htdocs">
     313  # For Apache 2.2
     314  <IfModule !mod_authz_core.c>
     315    Order allow,deny
     316    Allow from all
     317  </IfModule>
     318  # For Apache 2.4
     319  <IfModule mod_authz_core.c>
     320    Require all granted
     321  </IfModule>
     322</Directory>
     323}}}
     324
     325Another 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:
     326{{{#!ini
     327[trac]
     328htdocs_location = http://static.example.org/trac-common/
     329}}}
     330
     331Note that this makes it easy to have a dedicated domain serve those static resources, preferentially cookie-less.
     332
     333Of 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:
     334{{{#!sh
     335$ ln -s /path/to/trac/htdocs/common /var/www/static.example.org/trac-common
     336}}}
     337
     338==== Setting up the Plugin Cache
     339
     340Some 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.
     341
     342== Configuring Authentication
     343
     344Trac 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.
     345
     346The process of adding, removing, and configuring user accounts for authentication depends on the specific way you run Trac.
     347
     348Please refer to one of the following sections:
     349 * TracStandalone#UsingAuthentication if you use the standalone server, `tracd`.
     350 * [wiki:TracModWSGI#ConfiguringAuthentication TracModWSGI#ConfiguringAuthentication] if you use the Apache web server, with any of its front end: `mod_wsgi`, `mod_python`, `mod_fcgi` or `mod_fastcgi`.
     351 * TracFastCgi if you're using another web server with FCGI support (Cherokee, Lighttpd, !LiteSpeed, nginx)
     352
     353[trac:TracAuthenticationIntroduction] also contains some useful information for beginners.
     354
     355== Granting admin rights to the admin user
     356Grant admin rights to user admin:
     357{{{#!sh
     358$ trac-admin /path/to/myproject permission add admin TRAC_ADMIN
     359}}}
     360
     361This user will have an //Admin// navigation item that directs to pages for administering your Trac project.
     362
     363== Configuring Trac
     364
     365Configuration options are documented on the TracIni page.
     366
     367TracRepositoryAdmin provides information on configuring version control repositories for your project.
     368
     369In addition to the optional version control backends, Trac provides several optional features that are disabled by default:
     370* [TracFineGrainedPermissions#AuthzPolicy Fine-grained permission policy]
     371* [TracPermissions#CreatingNewPrivileges Custom permissions]
     372* [TracTickets#deleter Ticket deletion]
     373* [TracTickets#cloner Ticket cloning]
     374* [TracRepositoryAdmin#CommitTicketUpdater Ticket changeset references]
     375
     376== Using Trac
    308377
    309378Once 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.
    310379
    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.
     380Keep 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 [TracPermissions permissions] to authenticated users to see the full set of features.
