Installing Nginx+Unicorn on Red Hat OpenShift

This set of scripts and config files will help you set up the awesome combination of Unicorn and Nginx as a server environment for Ruby web applications on Red Hat's OpenShift platform while I finish my cartridge.

Notes

• Before you get started, you should read my post on how to set up Ruby 1.9 environment on OpenShift here: http://goo.gl/ufI5G This will (hopefully) get you started on building a Rails app on OpenShift the unofficial way (for now!).
