Dusty Candland | Sun Jan 30 2011 | aws, ec2, forever, haproxy, nodejs, ubuntu

Create an instance, I used one from here, Alestic, paste in the ami-xxxxxx value to find the one you want.

Create an security group with at least SSH and HTTP.

Save your private key and connect like:

ssh -i your_key.pem ubuntu@ec2-instance-location.amazonaws.com

Update and install the needed packages:

sudo apt-get update sudo apt-get install git-core g++ make curl libssl-dev

Install node, get latest url at NodeJS.org

curl -O http://nodejs.org/dist/node-v0.2.6.tar.gz tar -xvzf node-v0.2.6.tar.gz cd node-v0.2.6 ./configure make sudo make install

Node Package Manager

Install Node Package Manager.

sudo chown -R $USER /usr/local/{share/man,bin,lib/node} curl http://npmjs.org/install.sh | sh

Forever

This will be used to keep your node process running, forever. Restarting as needed.

keep NodeJS running with Forever
