     1= Installing Trac as CGI

     6  ''Please note that using Trac via CGI is the slowest deployment method available. It is slower than [TracModPython mod_python], [TracFastCgi FastCGI] and even [trac:TracOnWindowsIisAjp IIS/AJP] on Windows.''

     9CGI 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
     11trac-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.
     14
     15== Apache web-server configuration
     16
     17In [http://httpd.apache.org/ Apache] there are two ways to run Trac as CGI:
     18
     19 1. Use a `ScriptAlias` directive that maps an URL to the `trac.cgi` script (recommended)
     20 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.
     21
     22To make Trac available at `http://yourhost.example.org/trac` add `ScriptAlias` directive to Apache configuration file, changing `trac.cgi` path to match your installation:
     23{{{#!apache
     24ScriptAlias /trac /path/to/www/trac/cgi-bin/trac.cgi
     25}}}
     26
     27 ''Note that this directive requires enabled `mod_alias` module.''
     28
     29If you're using Trac with a single project you need to set its location using the `TRAC_ENV` environment variable:
     30{{{#!apache
     31<Location "/trac">
     32  SetEnv TRAC_ENV "/path/to/projectenv"
     33</Location>
     34}}}
     35
     36Or to use multiple projects you can specify their common parent directory using the `TRAC_ENV_PARENT_DIR` variable:
     37{{{#!apache
     38<Location "/trac">
     39  SetEnv TRAC_ENV_PARENT_DIR "/path/to/project/parent/dir"
     40</Location>
     41}}}
     42
     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 ...":''
     44
     45{{{#!python
     46    import os
     47    os.environ['TRAC_ENV'] = "/path/to/projectenv"
     48}}}
     49
     50 '' Or for TRAC_ENV_PARENT_DIR: ''
     51
     52{{{#!python
     53    import os
     54    os.environ['TRAC_ENV_PARENT_DIR'] = "/path/to/project/parent/dir"
     55}}}
     56
     57If you are using the [http://httpd.apache.org/docs/suexec.html Apache suEXEC] feature please see [trac:ApacheSuexec].
     58
     59On 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
     61=== Using WSGI
     62
     63You 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.
