Running MoinMoin with Apache’s mod_proxy_fcgi
While MoinMoin works great with mod_fcgid, it does not work with mod_proxy_fcgi out of the box. Luckily, adapting it for mod_proxy_fcgi is not very hard. The moin.cgi script included in the MoinMoin distribution is a good starting point. The following script has been derived from the version of this script that is included in MoinMoin 1.9.8.

If this script is placed in the same directory as wikiconfig.py, you should not have to change any paths. Otherwise, you have to add a sys.path.insert(...) line (see the corresponding commented section in the script).
Assuming that you saved the script as moin-fcgi-server, you can run start the server using one of the following lines:
moin-fcgi-server -i /path/to/fcgi.sock
The first variant makes the server listen on TCP port 8991 on the loopback interface. Assuming that the wiki is available at http://example.com/mywiki/, the following line should be added to the respective VirtualHost section of the Apache configuration:
When using the second variant, the server listens on a UNIX domain socket and the Apache configuration is slightly different:
The flup FastCGI server resets the permissions of the socket to match the umask of the process, so permission or ownership changes of the socket are not preserved across restarts. Unfortunately, there is no way to change this without making changes to the MoinMoin code. For this reason, using Unix domain sockets is only feasible when the MoinMoin FastCGI server is running as the same user as the Apache webserver.
