Installing Trac as CGI
Table of Contents
Please note that using Trac via CGI is the slowest deployment method available. It is slower than mod_wsgi, mod_python, FastCGI and even IIS/AJP on Windows.
CGI 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.
Apache web-server configuration
In Apache there are two ways to run Trac as CGI:
- Use a
ScriptAlias
directive that maps a URL to thetrac.cgi
script (recommended) - Copy the
trac.cgi
file into the directory for CGI executables used by your web server (commonly namedcgi-bin
). You can also create a symbolic link, but in that case make sure that theFollowSymLinks
option is enabled for thecgi-bin
directory.
To make Trac available at http://yourhost.example.org/trac
add ScriptAlias
directive to Apache configuration file, changing trac.cgi
path to match your installation:
ScriptAlias /trac /path/to/www/trac/cgi-bin/trac.cgi
Note that this directive requires that the
mod_alias
module is enabled.
If you're using Trac with a single project you need to set its location using the TRAC_ENV
environment variable:
<Location "/trac"> SetEnv TRAC_ENV "/path/to/projectenv" </Location>
Or to use multiple projects you can specify their common parent directory using the TRAC_ENV_PARENT_DIR
variable:
<Location "/trac"> SetEnv TRAC_ENV_PARENT_DIR "/path/to/project/parent/dir" </Location>
Note that the
SetEnv
directive requires that themod_env
module is enabled.
An alternative to SetEnv
is editing TRAC_ENV
or TRAC_ENV_PARENT_DIR
in trac.cgi
:
os.environ['TRAC_ENV'] = "/path/to/projectenv"
os.environ['TRAC_ENV_PARENT_DIR'] = "/path/to/parent/dir"
If you are using the Apache suEXEC feature please see ApacheSuexec.
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).
Using WSGI
You can run a WSGI handler under CGI. You can write your own application function, or use the deployed trac.wsgi's application.
