    9 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:
    10 {{{#!sh
    11 trac-admin /path/to/env deploy /path/to/www/trac
    12 }}}
    13 `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.

    1511== Apache web-server configuration
    … …  
    1713In [http://httpd.apache.org/ Apache] there are two ways to run Trac as CGI:
    1814
    19  1. Use a `ScriptAlias` directive that maps an URL to the `trac.cgi` script (recommended)
     15 1. Use a `ScriptAlias` directive that maps a URL to the `trac.cgi` script (recommended)
    2016 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.

    2925If you're using Trac with a single project you need to set its location using the `TRAC_ENV` environment variable:

    43  ''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.''
     40
     41An alternative to `SetEnv` is editing `TRAC_ENV` or `TRAC_ENV_PARENT_DIR` in `trac.cgi`:
    4442
    4543{{{#!python
    46     import os
    4744    os.environ['TRAC_ENV'] = "/path/to/projectenv"
    4845}}}
    4946
    50  '' Or for TRAC_ENV_PARENT_DIR: ''
    51 
    5247{{{#!python
    53     import os
    54     os.environ['TRAC_ENV_PARENT_DIR'] = "/path/to/project/parent/dir"
     48    os.environ['TRAC_ENV_PARENT_DIR'] = "/path/to/parent/dir"

    59 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).

     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
