Once FastCGI is setup, you are ready to configure Apache.
Server address format: http://rt.server.com
RT lines added to the virtual host:
DocumentRoot "/var/www/rt/share/html" AddDefaultCharset UTF-8 Alias /NoAuth/images /var/www/rt/share/html/NoAuth/images/ AddHandler fastcgi-script fcgi ScriptAlias / /var/www/rt/sbin/rt-server.fcgi/
DO NOT FORGET TO REPLACE /var/www with your root address.
DO NOT FORGET TO RESTART APACHE
That is all you need.
