== Mongrel Cluster Plugin

Tool to help start/stop/restart multiple mongrel servers to use behind a load balancer like Apache 2.2 (mod_proxy_balancer), Lighttpd, Pound, Pen or Balance. This plugin adds an option to specify a number of Mongrel servers to launch, a range of ports, and a configuration file for the cluster. Use "-h" to see command syntax.

Configure cluster and write configuration file:
mongrel_rails cluster::configure  

Start cluster:
mongrel_rails cluster::start

Restart cluster:
mongrel_rails cluster::restart

Stop cluster:
mongrel_rails cluster::stop

*Capistrano Recipe*

require 'mongrel_cluster/recipes'

cap -a configure_mongrel_cluster
