The Problem

Standard practices say no non-root process gets to talk to the Internet on a port less than 1024. How, then, could I get Node talking on port 80 on EC2? (I wanted it to go as fast as possible and use the smallest possible share of my teeny tiny little micro-instance's resources, so proxying through nginx or Apache seemed suboptimal.)

The temptingly easy but ultimately wrong solution:

Alter the port the script talks to from 8000 to 80:

}).listen(80);

# Why use RAILS_ROOT and RAILS_ENV? Because this way we can tell our Sinatra app about the config file:
# $ RAILS_ENV=production resque-web rails_root/config/initializers/resque.rb
require 'resque'

rails_root = ENV['RAILS_ROOT']  || File.dirname(__FILE__) + '/../..'
rails_env = ENV['RAILS_ENV']    || 'development'

resque_config = YAML.load_file(rails_root + '/config/resque.yml')
Resque.redis = resque_config[rails_env]

Running redis using upstart on Ubuntu

I've been trying to understand how to setup systems from the ground up on Ubuntu. I just installed redis onto the box and here's how I did it and some things to look out for.

To install:
