How to: Install Ruby on Rails using RVM

This is just a quick complement of the article (</install-nginx-agent-newrelic-ubuntu-server/> “How to: Install the NginX Agent for NewRelic in an Ubuntu server”). As I mentioned there if you need Ruby for something other than running a plugin agent like in a development web server RVM is the way to go. Below are the quick instructions on how to deploy Ruby using RVM:

sudo apt-get install curl

 curl -L get.rvm.io | bash -s stable

 source ~/.rvm/scripts/rvm

 rvm requirements

 rvm install 2.1.0

 rvm use 2.1.0

 rvm —default use 2.1.0

 gem install rails -v 4.0.2

As always, check out https://rvm.io/ for the latest up to date information on RVM.
