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.

    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.

     41An alternative to `SetEnv` is editing `TRAC_ENV` or `TRAC_ENV_PARENT_DIR` in `trac.cgi`:

    4143{{{#!python
    42     import os
    4344    os.environ['TRAC_ENV'] = "/path/to/projectenv"

    55 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
