Jon Maddox was inspired by Ruby Inside's previous post about init.d startup scripts, and has put together a UNIX init.d script that can start, stop, and restart all of your Rails apps' Mongrel clusters automatically. The benefit of Jon's approach is that unlike with the startup script supplied with Mongrel, you don't need to manually copy in each Mongrel configuration file to make it work. Instead, you tell the script under which folder your apps are hosted, and it looks for your Mongrel cluster configuration files automatically. This is an ideal script if you have multiple Rails apps on a single machine and want to stop and start the entire set at once.
