##Setup your server (this would ideally be done with automated provisioning)

• add a deploy user with password-less ssh see this gist
• install forever npm install -g forever

##Install flightplan

• npm install -g flightplan
• in your project folder npm install flightplan --save-dev
• create a flightplan.js file

Deploying a node app with Forever is great...until your server restarts unexpectedly. Then your app stops running and you have to re-deploy.

To get around this, we're going to run our node app as an Upstart service. Upstart services are great, because, once started, the system auto-restarts them if they fail, or if the server restarts.

###Step 1: Create a service for your node app

• ssh in as root ssh root@youripaddress
• Create a node-app.conf file in /etc/init
  IMPORTANT: whatever filename you pick is what you will use to start|stop|restart your service i.e. service node-app start

upstream project {
  server 22.22.22.2:3000;
  server 22.22.22.3:3000;
  server 22.22.22.5:3000;
}

server {
  listen 80;

  location / {

Here's all you have to do to add clustering to your node.js application.

• save this code as cluster.js, and run cluster.js instead of server.js (or /bin/www, or whatever it's called for your project)
• the only line you'll need to change is the last line - it needs to point to the location of your server.js file

var cluster = require('cluster');

if (cluster.isMaster) {
  // Count the machine's CPUs
 var cpuCount = require('os').cpus().length;

###Let's install Vagrant###

• Install VirtualBox: https://www.virtualbox.org/
• Install Vagrant: http://vagrantup.com/

###Select a Vagrant Box from https://vagrantcloud.com###

#add it to your list of boxes
vagrant box add hashicorp/precise32
#create a new folder for your project & init vagrant

(wherever it says url.com, use your server's domain or IP)

Login to new server as root, then add a deploy user

sudo useradd --create-home -s /bin/bash deploy
sudo adduser deploy sudo
sudo passwd deploy

And Update the new password

echo 'Starting Provision on:' $1
sudo apt-get update

sudo systemctl stop nginx.service
sudo rm -rf /etc/nginx/sites-enabled/default

echo "upstream testapp {
  server 10.0.0.11;

Creating a new user on Linux

I prefer to use cmder on Windows. It provides most comment linux commends out of the box.

Create a node.js project

# install express-generator
npm install -g express-generator
