Node+cluster on Amazon EC2 Quickstart

node-ec2-ubuntu-cluster

#First you'll need to Signup for AWS/EC2 and generate a key pair. Google it, there should be plenty of
#tutorials. 

#Next, create an instance using the AWS Management Console and log into it using your key pair. 
#You can find the AMI's here https://help.ubuntu.com/community/EC2StartersGuide 
#I picked a 64bit 10.04 LTS AMI in US-East.

#Install node's perquisites (or those that aren't the default ubuntu LTS ami):
sudo apt-get update
sudo apt-get install build-essential libssl-dev

#Grab that latest node tarball - http://nodejs.org/#download
wget http://nodejs.org/dist/node-v0.4.1.tar.gz
tar xzf node-v0.4.1.tar.gz 
cd node-v0.4.1

#install node in the home directory, we should probably have created a non-sudo user for this
./configure --prefix=~/local 
make install

#put node in your path
export PATH=$PATH:/home/ubuntu/local/bin
source ~/.bashrc

#Setup npm, this makes life much easier
mkdir ~/git
cd ~/git
git clone https://github.com/isaacs/npm.git
cd npm/
make install

#setup nvm for easily switching between node versions as things change so quickly
npm install nvm

#install 'cluster' - https://github.com/LearnBoost/cluster
npm install cluster

#setup hello world example
mkdir ~/git/sandbox
cd ~/git/sandbox
#<edit cluster.js> to contain cluster example:

      var cluster = require('cluster')
        , http = require('http');

      var server = http.createServer(function(req, res){
        console.log('%s %s', req.method, req.url);
        var body = 'Hello World';
        res.writeHead(200, { 'Content-Length': body.length });
        res.end(body);
      });

      cluster(server)
        .use(cluster.logger('logs'))
        .use(cluster.stats())
        .use(cluster.pidfiles('pids'))
        .use(cluster.cli())
        .use(cluster.repl(8888))
        .listen(3000);

#Test it! 
node cluster.js

#Using the domain you ssh'd into earlier, browse to http://<domain>:3000, you should see hello world

#From the EC2 instance, login into the cluster admin interface:
telnet 0 8888
