Don't use this verbatim. Just showcases the idea behind HOW to get everything setup

Initial setup

# Add a git user
adduser git

# Add your ssh key
sudo -u git mkdir ~git/.ssh/
sudo cp id_rsa.pub ~git/.ssh/authorized_keys
sudo chown -R git.git ~git/.ssh

# Make a repo
sudo -u git mkdir ~git/MyRepo.git
sudo -u git 'cd ~git/MyRepo.git && git init --bare'

# Log out and go to the local git repo on your development machine
git remote add whatever_you_wanna_call_this git@myhost.name.com:~/MyRepo.git

# Then when you want to deploy just do `git push whatever_you_wanna_call_this master`
# Git will sync any changes you've made locally with the remote end.
# The post receive scripts below can be used to deploy rails or node apps

post-receive-node

#!/bin/sh

# Same thing as the above post-receive file, only for a node app

AS_USER=`whoami`;

echo "============================";
echo "Deploying project";
echo "Username: $AS_USER";

unset GIT_DIR;

echo "Attempting to restart UDP server....";

echo "Attempting to restart Web server....";
forever stop server.js
forever start -o /var/log/myapp_web.log server.js
echo "============================";
echo 'Done.';

post-receive-ruby

#!/bin/sh

#
# This is a simple script for deploy a rail app using unicorn
# The git user should have rvm in their path (or the bundle and unicorn tools - wherever they may be)
#
# Copy this script to ~git/MyRepo.git/hooks/post-receive and then chmod +x
