    4 Trac is a lightweight project management tool that is implemented as a web-based application. Trac is written in the Python programming language and needs a database (either [http://sqlite.org/ SQLite], [http://www.postgresql.org/ PostgreSQL], or [http://mysql.com/ MySQL] works). For HTML rendering, Trac uses the [http://www.clearsilver.net/ ClearSilver] templating system.
    5 
    6 What follows are generic instructions for installing and setting up Trac and its requirements. While you can find instructions for installing Trac on specific systems at [http://projects.edgewall.com/trac/wiki/TracInstallPlatforms TracInstallPlatforms] on the main Trac site, please be sure to first read through these general instructions to get a good understanding of the tasks involved.

     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.
     5
     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.
     7
     8If you're interested in contributing new translations for other languages or enhancing the existing translations, please have a look at [trac:wiki:TracL10N TracL10N].

     10What 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], please '''first read through these general instructions''' to get a good understanding of the tasks involved.

     14== Dependencies
     15=== Mandatory Dependencies
    1016To install Trac, the following software packages must be installed:
    1117
    12  * [http://www.python.org/ Python], version >= 2.3.
    13    * For RPM-based systems you might also need the `python-devel` and `python-xml` packages.
    14    * If you want to use Trac with Subversion on Windows, note that there are no precompiled Subversion bindings for Python 2.4, so you probably need Python 2.3.
    15     * 2006-09-20: This seems to be no longer true, see http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91. For subversion 1.4.0 python 2.4 binary bindings are available.
    16  * [http://www.clearsilver.net/ ClearSilver], version >= 0.9.3
    17    * With python-bindings (`./configure --with-python=/usr/bin/python`)
    18  * You also need a database system and the corresponding python drivers for it.
    19    The database can be either SQLite, PostgreSQL or MySQL ''(experimental)''.
    20 
    21 === For SQLite ===
    22 
    23  * [http://www.sqlite.org/ SQLite], version 2.8.x or 3.x (preferred)
    24  * [http://pysqlite.org/ PySQLite], version 1.x (for SQLite 2.x) or version 2.x (for SQLite 3.x). For details see [http://trac.edgewall.org/wiki/PySqlite PySqlite]
    25 
    26 ''Note: Versions of Trac prior to 0.9 do '''not''' work with PySQLite 2.x.''
    27 
    28 ''Note: It appears that PySQLite 2.x is required for Trac 0.9+/SQLite 3.x if you plan to use the 'trac-post-commit-hook.py' script available from the 'contrib' section of the source repository.''
    29 
    30 ''Note: Users of Mac OS X please take care; the Apple-supplied SQLite contains additional code to support file locking on network filesystems like AFP or SMB. This is not presently (3.3.6) in the mainline sources, so if you build your own SQLite from source it will not function correctly on such filesystems - typically it gives the error "{{{database is locked}}}". [http://www.alastairs-place.net/2006/07/sqlite_and_mac/ A patch] is available for version 3.3.6, based on Apple's code, otherwise you're probably best off using the Apple supplied version (presently 3.1.3).''
    31 
    32 === For PostgreSQL ===
    33 
    34  * [http://www.postgresql.org/ PostgreSQL]
    35  * [http://initd.org/projects/psycopg2 psycopg2] or [http://pypgsql.sourceforge.net/ pyPgSQL]
    36 
    37 ''Note: PostgreSQL support requires Trac version 0.9 or later.''
    38 
    39 === For MySQL ===
    40 
    41 '''Warning''': MySQL support is currently experimental. That means it works for some people, but has not been tested extensively yet.
    42 
    43  * [http://mysql.com/ MySQL], version 4.1 or later
    44  * [http://sf.net/projects/mysql-python MySQLdb], version 1.2.1 or later
    45 
    46 ''Note: MySQL support requires Trac version 0.10 or later.''
    47 
    48 === Optional Requirements ===
    49 
    50 ==== Version Control System ====
    51  * [http://subversion.tigris.org/ Subversion], version >= 1.0. (either 1.2.3 or >= 1.3.1 recommended) and corresponding [http://svnbook.red-bean.com/svnbook-1.1/ch08s02.html#svn-ch-8-sect-2.3 Python bindings]. For troubleshooting, check [http://projects.edgewall.com/trac/wiki/TracSubversion TracSubversion]
    52    * Trac uses the [http://www.swig.org/ SWIG] bindings included in the Subversion distribution, '''not''' [http://pysvn.tigris.org/ PySVN] (which is sometimes confused with the standard SWIG bindings).
    53    * If Subversion was already installed without the SWIG bindings, you'll need to re-`configure` Subversion and `make swig-py`, `make install-swig-py`.
    54  * Support for other version control systems is provided via third-parties. See [http://projects.edgewall.com/trac/wiki/PluginList PluginList] and [http://projects.edgewall.com/trac/wiki/VersioningSystemBackend VersioningSystemBackend].
    55 
    56 ==== Web Server ====
    57  * A CGI-capable web server (see TracCgi), or
    58  * a [http://www.fastcgi.com/ FastCGI]-capable web server (see TracFastCgi), or
    59  * [http://httpd.apache.org/ Apache] with [http://www.modpython.org/ mod_python 3.1.3+] (see TracModPython)
    60     * When installing mod_python the development versions of Python and Apache are required (actually the libraries and header files)
    61 
    62 For those stuck with Apache 1.3, it is also possible to get Trac 0.8.4 working with [http://www.modpython.org/ mod_python 2.7] (see [wiki:TracModPython2.7 TracModPython2.7]). This hasn't been tested with Trac 0.9, so it may or may not work.
    63 
    64 ==== Other Python Utilities ====
    65  * [http://peak.telecommunity.com/DevCenter/setuptools setuptools], version >= 0.6 for using plugins (see TracPlugins)
    66  * [http://docutils.sourceforge.net/ docutils], version >= 0.3.9 for WikiRestructuredText.
    67  * [http://silvercity.sourceforge.net/ SilverCity] and/or [http://www.gnu.org/software/enscript/enscript.html Enscript] for [wiki:TracSyntaxColoring syntax highlighting].
    68     * Note that !SilverCity 0.9.6 has a [http://sourceforge.net/tracker/index.php?func=detail&aid=1424436&group_id=45693&atid=443739 bug] that breaks Python syntax highlighting in Trac. Until an update is made available, we recommend using version 0.9.5.
    69 
    70 '''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 [http://projects.edgewall.com/trac/wiki/MailingList MailingList] or [http://projects.edgewall.com/trac/wiki/IrcChannel IrcChannel].
    71 
    72 Please refer to the documentation of these packages to find out how they are best installed. In addition, most of the [http://projects.edgewall.com/trac/wiki/TracInstallPlatforms platform-specific instructions] also describe the installation of the dependencies. Keep in mind however that the information there might concern older versions of Trac than the one you're installing (in particular,
    73 there are still some pages that are about Trac 0.8).
    74 
    75 == Installing Trac ==
    76 
    77 Like most Python programs, the Trac Python package is installed by running the following command at the top of the source directory:
    78 {{{
    79 $ python ./setup.py install
    80 }}}
    81 
    82 ''Note: you'll need root permissions or equivalent for this step.''
    83 
    84 This will byte-compile the python source code and install it in the `site-packages` directory
    85 of your Python installation. The directories `cgi-bin`, `templates`, `htdocs`, `wiki-default` and `wiki-macros` are all copied to `$prefix/share/trac/`. `conf` and `plugins` stub directories are also created under `$prefix/share/trac/` (''since [milestone:0.10]'').
    86 
    87 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.
    88 
    89 === Advanced Options ===
    90 
    91 To install Trac to a custom location, or find out about other advanced installation options, run:
    92 {{{
    93 $ python ./setup.py install --help
    94 }}}
    95 
    96 Also see [http://docs.python.org/inst/inst.html Installing Python Modules] for detailed information.
    97 
    98 Specifically, you might be interested in:
    99 {{{
    100 $ python ./setup.py install --prefix=/path/to/installdir
    101 }}}
    102 
    103 == Creating a Project Environment ==
    104 
    105 A [wiki:TracEnvironment Trac environment] is the backend storage where Trac stores information like wiki pages, tickets, reports, settings, etc. An environment is basically a directory that contains a human-readable configuration file and various other files and directories.
    106 
    107 A new environment is created using [wiki:TracAdmin trac-admin]:
    108 {{{
     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.
     28
     29==== For the SQLite database #ForSQLite
     30
     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.
     34
     35==== For the PostgreSQL database #ForPostgreSQL
     36
     37You need to install the database and its Python bindings:
     38 * [https://www.postgresql.org/ PostgreSQL], version 9.1 or later
     39 * [https://pypi.org/project/psycopg2 psycopg2], version 2.0 or later
     40
     41See [trac:DatabaseBackend#Postgresql DatabaseBackend] for details.
     42
     43==== For the MySQL database #ForMySQL
     44
     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.
     51
     52=== Optional Dependencies
     53
     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].
     64}}}
     65
     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])
     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
     91
     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://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
     101   for WikiRestructuredText.
     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].
     107
     108{{{#!div style="border: 1pt dotted; margin: 1em"
     109**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].
     110}}}
     111
     112Please 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''.
     113
     114== Installing Trac
     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.
     119
     120=== Using `pip`
     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.
     180
     181== Creating a Project Environment
     182
     183A [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.
     184
     185A new environment is created using [TracAdmin trac-admin]:
     186{{{#!sh
    109187$ trac-admin /path/to/myproject initenv
    110188}}}
    111189
    112 [wiki:TracAdmin trac-admin] will prompt you for the information it needs to create the environment, such as the name of the project, the type and the path to an existing [wiki:TracEnvironment#SourceCodeRepository source code repository], the [wiki:TracEnvironment#DatabaseConnectionStrings database connection string], and so on. If you're not sure what to specify for one of these options, just leave it blank to use the default value. The database connection string in particular will always work as long as you have SQLite installed. Leaving the path to the source code repository empty will disable any functionality related to version control, but you can always add that back when the basic system is running.
    113 
    114 Also note that the values you specify here can be changed later by directly editing the [wiki:TracIni] configuration file.
    115 
    116 ''Note: The user account under which the web server runs will require write permissions to the environment
    117 directory and all the files inside.''
    118 
    119 
    120 == Running the Standalone Server ==
    121 
    122 After having created a Trac environment, you can easily try the web interface by running the standalone server [wiki:TracStandalone tracd]:
    123 {{{
     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.
     195
     196Finally, 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:
     197{{{#!sh
     198$ chown -R apache:apache /path/to/myproject
     199}}}
     200
     201The 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).
     202
     203{{{#!div class=important
     204'''Warning:''' Please only use ASCII-characters for account name and project path, unicode characters are not supported there.
     205}}}

     207== Deploying Trac
     208
     209{{{#!div style="border: 1pt dotted; margin: 1em"
     210**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.
     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
     214To 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`.
     215{{{#!sh
     216export PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1
     217}}}
     218
     219Alternatively, the variable can be set in the shell before executing `tracd`:
     220{{{#!sh
     221$ PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1 tracd --port 8000 /path/to/myproject
     222}}}
     223
     224If 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`.
     225}}}
     226
     227=== Running the Standalone Server
     228
     229After having created a Trac environment, you can easily try the web interface by running the standalone server [TracStandalone tracd]:
     230{{{#!sh
    124231$ tracd --port 8000 /path/to/myproject
    125232}}}
    126233
    127 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.
    128 
    129 
    130 == Running Trac on a Web Server ==
    131 
    132 Trac provides three options for connecting to a “real” web server: [wiki:TracCgi CGI], [wiki:TracFastCgi FastCGI] and [wiki:TracModPython mod_python]. For decent performance, it is recommended that you use either FastCGI or mod_python.
    133 
    134 == Configuring Authentication ==
    135 
    136 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:
    137 
    138  * TracStandalone if you use the standalone server, `tracd`.
    139  * TracCgi if you use the CGI or FastCGI methods.
    140  * TracModPython if you use the mod_python method.
    141 
    142 == Using Trac ==
    143 
    144 Once you have your Trac site up and running, you should be able to browse your subversion repository, create tickets, view the timeline, etc.
    145 
    146 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.
     234Then, open 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:
     235{{{#!sh
     236$ tracd -s --port 8000 /path/to/myproject
     237}}}
     238
     239=== Running Trac on a Web Server
     240
     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.
     248
     249==== Generating the Trac cgi-bin directory #cgi-bin
     250
     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}}}
     265
     266==== Mapping Static Resources
     267
     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 `$env/htdocs` directory. This is probably appropriate for most installations but may not be what you want if, for example, you wish to upload plugins through the //Plugins// administration page.
     275
     276The `deploy` command creates an `htdocs` directory with:
     277 - `common/` - the static resources of Trac
     278 - `site/` - a copy of the environment's `htdocs/` directory
     279 - `shared` - the static resources shared by multiple Trac environments, with a location defined by the `[inherit]` `htdocs_dir` option
     280 - `<plugin>/` - one directory for each resource directory provided by the plugins enabled for this environment
     281
     282The example that follows will create a single `/chrome` alias. If that isn't the correct approach for your installation you simply need to create more specific aliases:
     283{{{#!apache
     284Alias /trac/chrome/common /path/to/trac/htdocs/common
     285Alias /trac/chrome/site /path/to/trac/htdocs/site
     286Alias /trac/chrome/shared /path/to/trac/htdocs/shared
     287Alias /trac/chrome/<plugin> /path/to/trac/htdocs/<plugin>
     288}}}
     289
     290===== Example: Apache and `ScriptAlias` #ScriptAlias-example
     291
     292Assuming the deployment has been done this way:
     293{{{#!sh
     294$ 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
     300
     301<Directory "/path/to/www/trac/htdocs">
     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>
     311</Directory>
     312}}}
     313
     314If using mod_python, add this too, otherwise the alias will be ignored:
     315{{{#!apache
     316<Location "/trac/chrome/common">
     317  SetHandler None
     318</Location>
     319}}}
     320
     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:
     322{{{#!apache
     323Alias /trac/chrome/site /path/to/projectenv/htdocs
     324
     325<Directory "/path/to/projectenv/htdocs">
     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>
     335</Directory>
     336}}}
     337
     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:
     339{{{#!ini
     340[trac]
     341htdocs_location = http://static.example.org/trac-common/
     342}}}
     343
     344Note that this makes it easy to have a dedicated domain serve those static resources, preferentially cookie-less.
     345
     346Of 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:
     347{{{#!sh
     348$ ln -s /path/to/trac/htdocs/common /var/www/static.example.org/trac-common
     349}}}
     350
     351==== Setting up the Plugin Cache
     352
     353Some 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.
     354
     355== Configuring Authentication
     356
     357Trac 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.
     358
     359The process of adding, removing, and configuring user accounts for authentication depends on the specific way you run Trac.
     360
     361Please refer to one of the following sections:
     362 * TracStandalone#UsingAuthentication if you use the standalone server, `tracd`.
     363 * [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`.
     364 * TracFastCgi if you're using another web server with FCGI support (Cherokee, Lighttpd, !LiteSpeed, nginx)
     365
     366[trac:TracAuthenticationIntroduction] also contains some useful information for beginners.
     367
     368== Granting admin rights to the admin user
     369Grant admin rights to user admin:
     370{{{#!sh
     371$ trac-admin /path/to/myproject permission add admin TRAC_ADMIN
     372}}}
     373
     374This user will have an //Admin// navigation item that directs to pages for administering your Trac project.
     375
     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]
     386* [TracTickets#cloner Ticket cloning]
     387* [TracRepositoryAdmin#CommitTicketUpdater Ticket changeset references]
     388
     389== Using Trac
     390
     391Once 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.
     392
     393Keep 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.
