Installing Trac as CGI
Table of Contents
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
ScriptAliasdirective that maps an URL to the
- Copy the
trac.cgifile 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
FollowSymLinksoption is enabled for the
To make Trac available at
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 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
<Location "/trac"> SetEnv TRAC_ENV_PARENT_DIR "/path/to/project/parent/dir" </Location>
Note that the
SetEnvdirective requires enabled
mod_envmodule. It is also possible to set TRAC_ENV in trac.cgi. Just add the following code between "try:" and "from trac.web …":
import os os.environ['TRAC_ENV'] = "/path/to/projectenv"
Or for TRAC_ENV_PARENT_DIR:
import os os.environ['TRAC_ENV_PARENT_DIR'] = "/path/to/project/parent/dir"
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).
