Ruby 1.9.3 stable, RVM, nginx, passenger on Amazon Linux AMI (CentOS, 03-2013)

This combines the instructions on a few different tutorials:

Tabula EC2 AMI quickstart - A nice illustrated How-To for a basic EC2 setup, including permissions setup. The instructions apply to a specific demo app but apply to any EC2 usage
Code by Zack » Getting RVM set up on Amazon EC2 - How to install the latest stable version of Ruby (1.9.3p392) with RVM
Code by Zack » Setting up Passenger with rvm on Ubuntu - Installing Passenger and using it to set up nginx. The instructions at the end of Zack's guide on creating an init script apply to Ubuntu only.

Setting up nginx

Instructions from here, even though it applies to Ubuntu http://codebyzack.com/2012/08/18/setting-up-passenger-with-rvm-on-ubuntu/

rvmsudo passenger-install-nginx-module

Setting up nginx centos

Using a config template originally outlined at SliceHost, we point it to where nginx is installed in this particular set up. See the modified script at my gist here: https://gist.github.com/dannguyen/5415991

sudo nano /etc/init.d/nginx

# Make script executable
sudo chmod +x /etc/init.d/nginx

sudo /sbin/chkconfig nginx on

# sanity check
sudo /sbin/chkconfig --list nginx

# should output:
#	nginx           0:off   1:off   2:on    3:on    4:on    5:on    6:off

Running nginx

Reboot the instance

These commands should work:

sudo /etc/init.d/nginx start
sudo /etc/init.d/nginx stop
sudo /etc/init.d/nginx restart
sudo /etc/init.d/nginx reload
sudo /etc/init.d/nginx status
sudo /etc/init.d/nginx configtest
