##Install git

sudo yum install git-core

##Create ssh directory since it doesn't exists by default on the Amazon AMI

sudo mkdir /var/www/.ssh
sudo chown -R apache:apache /var/www/.ssh/

##Generate key for apache user

sudo -Hu apache ssh-keygen -t rsa  # chose "no passphrase"
sudo cat /var/www/.ssh/
# Add the key as a "deploy key" at

##Get the repo

cd /var/www/
sudo chown -R apache:apache html
sudo -Hu apache git clone html

##Setup the update script

sudo -Hu apache nano html/update.php
<?php `git pull`; ?>

I had to do a little digging myself. I forgot that on an EC2 instance, all you have to do is type sudo su to become root. Then you can run sudo commands to your heart's content.

Since you will likely want to step out of the root role (you should when you're done, even if you don't want to), you can run su ec2-user to get back to where you were.

Is this is a safe mechanism? Like putting an update script in the root folder?
