Puppet load balancing: nginx + passenger

As the 3.x Series no longer supports mongrel, nginx + passenger is used for load balancing. Previously, nginx + mongrel and puppet version were released in the 2.7 series, so they can still be used;

Environment Description:

Operating System: centos 5.8 64-bit

Puppet version: 3.1 Series

So far, the puppet Server Load balancer has ended. The combination of nginx and passenger and mongrel has been completed.
