    410Trac 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.

    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 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, as usual.

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

    121 == Installing Trac ==
     127== Installing Trac
    122128=== Using `easy_install`
    123129One way to install Trac is using [http://pypi.python.org/pypi/setuptools setuptools].
    124 With setuptools you can install Trac from the subversion repository;
     130With setuptools you can install Trac from the Subversion repository;
    125131
    126132A few examples:
    127133

    138143   either use a released version or install from source
    139144
     145{{{#!div style="border: 1pt dotted; margin: 1em"
     146**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].

    140149=== Using `pip`
    141150'pip' is an easy_install replacement that is very useful to quickly install python packages.

    143152
    144153Assuming you want to have your entire pip installation in `/opt/user/trac`
    145154
    146155 -
    147 {{{
    148 pip -E /opt/user/trac install trac psycopg2
     156 {{{#!sh
     157pip install trac psycopg2

    150159or
    151160 -
    152 {{{
    153 pip -E /opt/user/trac install trac mysql-python
    154 }}}
    155 
    156 Make sure your OS specific headers are available for pip to automatically build PostgreSQL (libpq-dev) or MySQL (libmysqlclient-dev) bindings.
     161 {{{#!sh
     162pip install trac mysql-python
     163}}}
     164
     165Make sure your OS specific headers are available for pip to automatically build PostgreSQL (`libpq-dev`) or MySQL (`libmysqlclient-dev`) bindings.
    157166
    158167pip 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`.
     
    160169All 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)
    161170
    162 Additionally, you can install several trac plugins (listed [http://pypi.python.org/pypi?:action=search&term=trac&submit=search here]) through pip.

    167176Of course, using the python-typical setup at the top of the source directory also works.
    168177
    169 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).

    180189The 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.
    181190

    210 == Creating a Project Environment ==
     219== Creating a Project Environment
    211220
    212221A [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.
    213222
    214223A new environment is created using [wiki:TracAdmin trac-admin]:
    215 {{{
     224{{{#!sh
    216225$ trac-admin /path/to/myproject initenv
    217226}}}
     
    222231For the other [DatabaseBackend database backends] you should plan ahead and already have a database ready to use at this point.
    223232
    224 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.
     233Since 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.
    225234
    226235Also note that the values you specify here can be changed later by directly editing the [TracIni conf/trac.ini] configuration file.
    227236
     237When 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 (though the best advice is to opt for a platform with sub-second timestamp resolution when possible regardless of the version of Trac you are running).
     238
    228239Finally, 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:
    229 {{{
    230 # chown -R apache.apache /path/to/myproject
    231 }}}
     240{{{#!sh
     241$ chown -R apache.apache /path/to/myproject
     242}}}
     243
     244The 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).

    240 === Running the Standalone Server ===
     253=== Running the Standalone Server
    241254
    242255After having created a Trac environment, you can easily try the web interface by running the standalone server [wiki:TracStandalone tracd]:
    243 {{{
     256{{{#!sh
    244257$ tracd --port 8000 /path/to/myproject
    245258}}}
    246259
    247260Then, 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:
    248 {{{
     261{{{#!sh
    249262$ tracd -s --port 8000 /path/to/myproject
    250263}}}
    251264
    252 === Running Trac on a Web Server ===
     265{{{#!div style="border: 1pt dotted; margin: 1em"
     266**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.
     267
     268To 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`.
     269{{{#!sh
     270export PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1
     271}}}
     272
     273Alternatively, the variable can be set in the shell before executing `tracd`:
     274{{{#!sh
     275$ PKG_RESOURCES_CACHE_ZIP_MANIFESTS=1 tracd --port 8000 /path/to/myproject
     276}}}
     277}}}
     278
     279=== Running Trac on a Web Server
    253280
    254281Trac provides various options for connecting to a "real" web server:
     
    260287Trac 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.

     289==== Generating the Trac cgi-bin directory #cgi-bin
    263290
    264291In 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].
    265292
    266293There 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:
    267 {{{
     294{{{#!sh
    268295mkdir -p /usr/share/trac/projects/my-project
    269296trac-admin /usr/share/trac/projects/my-project initenv

    277305Out 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).
     
    289317 - `<plugins>/` - one directory for each resource directory managed by the plugins enabled for this environment

    291 ===== Example: Apache and `ScriptAlias` ===== #ScriptAlias-example
     319===== Example: Apache and `ScriptAlias` #ScriptAlias-example
    292320
    293321Assuming the deployment has been done this way:
    294 {{{
     322{{{#!sh
    295323$ trac-admin /var/trac/env deploy /path/to/trac/htdocs/common
    296324}}}
    297325
    298326Add 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:
    299 {{{
     327{{{#!apache
    300328Alias /trac/chrome/common /path/to/trac/htdocs/common
    301329Alias /trac/chrome/site /path/to/trac/htdocs/site
     
    308336
    309337If using mod_python, you might want to add this too (otherwise, the alias will be ignored):
    310 {{{
     338{{{#!apache
    311339<Location "/trac/chrome/common/">
    312340  SetHandler None
     
    317345
    318346Similarly, 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):
    319 {{{
     347{{{#!apache
    320348Alias /trac/chrome/site /path/to/projectenv/htdocs
    321349
     
    327355
    328356Alternatively 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:
    329 {{{
     357{{{#!ini
    330358[trac]
    331359htdocs_location = http://static.example.org/trac-common/
     
    334362
    335363Of 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:
    336 {{{
     364{{{#!sh
    337365$ ln -s /path/to/trac/htdocs/common /var/www/static.example.org/trac-common
    338366}}}

    341 ==== Setting up the Plugin Cache ====
    342 
    343 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.
    344 
    345 == Configuring Authentication ==
    346 
    347 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.

    349377The process of adding, removing, and configuring user accounts for authentication depends on the specific way you run Trac.

     395=== Enable version control components
     396
     397Support 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.
     398
     399The 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.
     400
     401{{{#!ini
     402tracopt.versioncontrol.svn.* = enabled

     404
     405{{{#!ini
     406tracopt.versioncontrol.git.* = enabled
     407}}}
     408
     409After enabling the components, repositories can be configured through the "Repositories" admin panel or by editing [TracIni#repositories-section trac.ini].
     410
     411=== Automatic reference to the SVN changesets in Trac tickets
    366412
    367413You 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:
     
    370416
    371417This 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.
