Ubuntu 12.04, Ruby, Rails, Nginx, Unicorn and git-deploy

In the seemlingly endless search for the actual correct and easy way to deploy a Rails app, we have tried several ways. We tried out using Apache2 and running a cluster of Thin servers. With the built in threading of Puma we decided to use it with Nginx.

Server Setup

• Create new server
• Login to new server
  • ssh root@IPaddress (you can also use the domain name if you have the DNS setup already)
  • accept the RSA key
