Installing Trac as CGI
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:
trac-admin /path/to/env deploy /path/to/www/trac
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.
Apache web-server configuration
In Apache there are two ways to run Trac as CGI:
- Use a ScriptAlias directive that maps an URL to the trac.cgi script (recommended)
- 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.
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 enabled mod_alias module.
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 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 …":
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).
