Trac with FastCGI
Since version 0.9, Trac supports being run through the FastCGI interface. Like mod_python, this allows Trac to remain resident, and is faster than external CGI interfaces which must start a new process for each request. However, unlike mod_python, it is able to support SuEXEC. Additionally, it is supported by much wider variety of web servers.
Simple Apache configuration
# Enable fastcgi for .fcgi files # (If you're using a distro package for mod_fcgi, something like # this is probably already present) <IfModule mod_fastcgi.c> AddHandler fastcgi-script .fcgi FastCgiIpcDir /var/lib/apache2/fastcgi </IfModule> LoadModule fastcgi_module /usr/lib/apache2/modules/mod_fastcgi.so
You can either setup the TRAC_ENV as an overall default:
FastCgiConfig -initial-env TRAC_ENV=/path/to/env/trac
Or you can serve multiple Trac projects in a directory like:
FastCgiConfig -initial-env TRAC_ENV_PARENT_DIR=/parent/dir/of/projects
Configure ScriptAlias or similar options as described in TracCgi, but calling trac.fcgi instead of trac.cgi.
Simple Lighttpd Configuration
The FastCGI front-end was developed primarily for use with alternative webservers, such as lighttpd.
lighttpd is a secure, fast, compliant and very flexible web-server that has been optimized for high-performance environments. It has a very low memory footprint compared to other web servers and takes care of CPU load.
For using trac.fcgi with lighttpd add the following to your lighttpd.conf:
fastcgi.server = ("/trac" => ("trac" => ("socket" => "/tmp/trac-fastcgi.sock", "bin-path" => "/path/to/cgi-bin/trac.fcgi", "check-local" => "disable", "bin-environment" => ("TRAC_ENV" => "/path/to/projenv") ) ) )
Note that you will need to add a new entry to fastcgi.server for each separate Trac instance that you wish to run. Alternatively, you may use the TRAC_ENV_PARENT_DIR variable instead of TRAC_ENV as described above.
Relaunch lighttpd, and browse to http://yourhost.example.org/trac to access Trac.
