# See my blog post on this script: http://samsoff.es/posts/new-server-script
#
# This script installs everything needed to run a Ruby on Rails application on
# Nginx (with Passenger) and PostgreSQL on CentOS 5.4 and 5.5. init.d scripts
# are installed for Ngnix and PostgreSQL as well. Git and Bundler are also
# installed as many applications use Bundler for gem dependencies and git is
# often used in Gemfiles. ImageMagick is also installed. Port 80 and 443 are
# also opened in IPTables.
#
# The install takes about 20 minutes on average.
#
# All of the versions are the latest as of 07/13/2010. The lastest patch level
# for Ruby 1.8.7 is used. This is due to some applications having
# incompatibilities with Ruby 1.9.1.
#
# To easily add a new virtual host, add a file with `.conf` as its extension
# to `/usr/local/nginx/conf/virtual_hosts/`.
#
# Example virtual host: http://gist.github.com/314883#file_example.conf
#
# To run this script, simply run the following command as root:
# $ wget http://gist.github.com/raw/314865/new_server.sh;chmod +x new_server.sh;./new_server.sh
#

# General
set -e
# Note: changing prefix doesn't quite work due to my lack of shell scripting 
# knowledge, so don't change it :)

# To get the pg gem to install, I generally have to restart my shell so
