Bash script for deploying Meteor (1.0.3.1) app to CentOS 6 running forever (now using pm2)

meteor-plz.sh

#!/bin/bash

# https://gist.github.com/hellstad

# This is a script I use to automate deploying my meteor app from my git repository to my server running:
# CentOS 6 x86_64
# nginx 1.4.7
# node 0.10.33
# forever 0.13.0
# npm 1.4.28
# mongod 2.6.7
# meteor 1.0.2.1

# Usage:
# > chmod a+x meteor-plz.sh
# > ./meteor-plz.sh

# Run this from your SERVER's /home/username directory where you want to run your meteor app from.
# The script will prompt before deleting directories but USE AT OWN RISK AND DOUBLE CHECK THE CODE FOR YOUR SETUP!
# Errors? Check chown / chmod.
