    8 CGI script is the entrypoint that web-server calls when a web-request to an application is made. To generate the `trac.cgi` script run:
    9 {{{
    10 trac-admin /path/to/env deploy /path/to/www/trac
    11 }}}
    12 `trac.cgi` will be in the `cgi-bin` folder inside the given path. ''Make sure it is executable by your web server''. This command also copies `static resource` files to a `htdocs` directory of a given destination.
     9CGI script is the entrypoint that web-server calls when a web-request to an application is made. The `trac.cgi` script can be created using the `trac-admin <env> deploy <dir>` command which automatically substitutes the required paths, see TracInstall#cgi-bin. Make sure the script is executable by your web server.

    1613In [http://httpd.apache.org/ Apache] there are two ways to run Trac as CGI:
    1714
    18  1. Use a `ScriptAlias` directive that maps an URL to the `trac.cgi` script (recommended)
    19  2. Copy the `trac.cgi` file into the directory for CGI executables used by your web server (commonly named `cgi-bin`). You can also create a symbolic link, but in that case make sure that the `FollowSymLinks` option is enabled for the `cgi-bin` directory.
     15 1. Use a `ScriptAlias` directive that maps a URL to the `trac.cgi` script (recommended)
     16 1. Copy the `trac.cgi` file into the directory for CGI executables used by your web server (commonly named `cgi-bin`). You can also create a symbolic link, but in that case make sure that the `FollowSymLinks` option is enabled for the `cgi-bin` directory.

    2118To make Trac available at `http://yourhost.example.org/trac` add `ScriptAlias` directive to Apache configuration file, changing `trac.cgi` path to match your installation:
    22 {{{
     19{{{#!apache
    2320ScriptAlias /trac /path/to/www/trac/cgi-bin/trac.cgi
    2421}}}
    2522
    26  ''Note that this directive requires enabled `mod_alias` module.''
     23 ''Note that this directive requires that the `mod_alias` module is enabled.''
    2724
    2825If you're using Trac with a single project you need to set its location using the `TRAC_ENV` environment variable:
    29 {{{
     26{{{#!apache
    3027<Location "/trac">
    3128  SetEnv TRAC_ENV "/path/to/projectenv"
    … …  
    3431
    3532Or to use multiple projects you can specify their common parent directory using the `TRAC_ENV_PARENT_DIR` variable:
    36 {{{
     33{{{#!apache
    3734<Location "/trac">
    3835  SetEnv TRAC_ENV_PARENT_DIR "/path/to/project/parent/dir"
    … …  
    4037}}}
    4138
    42  ''Note that the `SetEnv` directive requires enabled `mod_env` module. It is also possible to set TRAC_ENV in trac.cgi. Just add the following code between "try:" and "from trac.web ...":''
     39  ''Note that the `SetEnv` directive requires that the `mod_env` module is enabled.''
    4340
    44 {{{
    45     import os
     41An alternative to `SetEnv` is editing `TRAC_ENV` or `TRAC_ENV_PARENT_DIR` in `trac.cgi`:
     42
     43{{{#!python
    4644    os.environ['TRAC_ENV'] = "/path/to/projectenv"
    4745}}}
    4846
    49  '' Or for TRAC_ENV_PARENT_DIR: ''
    50 
    51 {{{
    52     import os
    53     os.environ['TRAC_ENV_PARENT_DIR'] = "/path/to/project/parent/dir"
     47{{{#!python
     48    os.environ['TRAC_ENV_PARENT_DIR'] = "/path/to/parent/dir"
    5449}}}

    58 On some systems, you ''may'' need to edit the shebang line in the `trac.cgi` file to point to your real Python installation path. On a Windows system you may need to configure Windows to know how to execute a .cgi file (Explorer -> Tools -> Folder Options -> File Types -> CGI).

    60 === Using WSGI ===
     55=== Python Egg Cache
     56
     57The [TracInstall#egg-cache egg-cache] can be configured using an `os.environ` statement in `trac.cgi`, as shown above.
     58To do the same from the Apache configuration, use the `SetEnv` directive:
     59{{{#!apache
     60SetEnv PYTHON_EGG_CACHE /path/to/dir
     61}}}
     62
     63Put this directive next to where you set the path to the [TracEnvironment Trac environment], i.e. in the same `<Location>` block.
     64
     65{{{#!apache
     66 <Location /trac>
     67   SetEnv TRAC_ENV /path/to/projenv
     68   SetEnv PYTHON_EGG_CACHE /path/to/dir
     69 </Location>

     74=== Using WSGI
    6175
    6276You can run a [http://henry.precheur.org/python/how_to_serve_cgi WSGI handler] [http://pythonweb.org/projects/webmodules/doc/0.5.3/html_multipage/lib/example-webserver-web-wsgi-simple-cgi.html under CGI].  You can [wiki:TracModWSGI#Thetrac.wsgiscript write your own application function], or use the deployed trac.wsgi's application.
