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:

	# Author: Pieter Noordhuis
	# Description: Simple demo to showcase Redis PubSub with EventMachine
	#
	# Update 7 Oct 2010:
	# - This example does not appear to work with Chrome >=6.0. Apparently,
	# the WebSocket protocol implementation in the cramp gem does not work
	# well with Chrome's (newer) WebSocket implementation.
	#
	# Requirements:
	# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby

	// Declare the color as RGB; SASS will treat this as hex
	$green: rgb(27,224,63);
	// Declare an alpha
	$alpha: .5;
	// Declare another color variable as a color with an alpha
	$greenAlpha: rgba($green, $alpha);

	body {
	/* As RGB (which SASS actually ouputs as HEX) */
	background: $green;

	// --------------------------------------------------
	// Flexbox LESS mixins
	// The spec: http://www.w3.org/TR/css3-flexbox
	// --------------------------------------------------

	// Flexbox display
	// flex or inline-flex
	.flex-display(@display: flex) {
	display: ~"-webkit-@{display}";
	display: ~"-ms-@{display}box"; // IE10 uses -ms-flexbox

	Secure sessions are easy, but not very well documented.
	Here's a recipe for secure sessions in Node.js when NginX is used as an SSL proxy:

	The desired configuration for using NginX as an SSL proxy is to offload SSL processing
	and to put a hardened web server in front of your Node.js application, like:

	[NODE.JS APP] <- HTTP -> [NginX] <- HTTPS -> [PUBLIC INTERNET] <-> [CLIENT]

	Edit for express 4.X and >: Express no longer uses Connect as its middleware framework, it implements its own now.

	var cv = document.getElementById('cv');
	var c = cv.getContext('2d');
	var txtDiv = document.getElementById('txt');
	var fileBtn = document.getElementById("up-button");
	var img = new Image();
	img.src = 'a.jpg';
	img.onload = init; // 图片加载完开始转换
	fileBtn.onchange = getImg;

	// 根据灰度生成相应字符

	var data = "do shash'owania";
	var crypto = require('crypto');
	crypto.createHash('md5').update(data).digest("hex");

	var gulp = require('gulp');
	var gutil = require('gulp-util');
	var express = require('express');
	var path = require('path');
	var tinylr = require('tiny-lr');

	var createServers = function(port, lrport) {
	var lr = tinylr();
	lr.listen(lrport, function() {
	gutil.log('LR Listening on', lrport);
