Setting Up an Multi-Applications Rails Server on Ubuntu

Using RVM, PostgreSQL, NGINX, Unicorn and Capistrano

Today I will cover how to setup a multi-application Ruby on Rails server with RVM, NGINX, Unicorn, Capistrano and PostgreSQL on a fresh virtual private server running Linux Ubuntu Server 14.04. I will be using Rails 4.2.0 new applications as examples.

My current company asked me to configure this setup, they're using the IBM's Softlayer as the main datacenter, so the server that I am playing with is a Softlayer. Nothing special about it, but in this case I have decided to don't use Chef or anything like that, but to make the entire server by hand, because it's funnier, right? Let's go.
