Deploying Rails to Linode

Installing Ruby Enterprise Edition, Apache, MySQL, and Passenger for deploying Rails 3.0 applications.

Get a Linode, and set it up with Ubuntu 10.04 LTS so that you have till April 2013 to get updates. Once the Linode is formatted, boot it and continue on.

Set up an 'A' record in your DNS, pointing to the IP of your Linode. I'm using demo.napcs.com here.
