Den FCGI Server Starte ich mit:
/home/stephan/catalyst/SteJau/script/stejau_fastcgi.pl -l /tmp/SteJauWeb.socket -n 5 -p /tmp/SteJauWeb.pid -d

Hier noch ein kleines script womit dus einfach starten stoppen kannst:

(das restart klappt nicht nur start stop)

Mein Code in der vhostcfg:
FastCgiExternalServer /tmp/SteJau.fcgi -socket /tmp/SteJauWeb.socket
