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:

mislav

connection = Faraday::Connection.new('http://example.com') do |builder|
  builder.request :url_encoded  # for POST/PUT params
  builder.adapter :net_http
end

# same as above, short form:
connection = Faraday.new 'http://example.com'

# GET
connection.get '/posts'

set :test_log, "logs/capistrano.test.log"

namespace :deploy do
  before 'deploy:update_code' do
    puts "--> Running tests, please wait ..."
    unless system "bundle exec rake > #{test_log} 2>&1" #' > /dev/null'
      puts "--> Tests failed. Run `cat #{test_log}` to see what went wrong."
      exit
    else      
      puts "--> Tests passed"
