# Author: Michael van Rooijen
# Description:
#   A Rails Stack Installer for Ubuntu 8.04/9.04 with the light-weight and fast NginX Web Server.
#   This shell script will install a basic Rails Stack with a bunch of useful and commonly used utilities.
#   It will install Ruby Enterprise Edition with Phusion Passenger (Reduces Rails Application Memory Usage By Approx. 33%)
#   It will install some essential gems like mysql, sqlite, postgres etc.
#   It will install NginX Web Server
#   It will install the MySQL database
#   It will install Git
#   It will install these utilities: ImageMagick, FFMpeg, Memcached
#   It will install these smaller utilities: rsync, gpm, tree and some more.
#   It will setup the "gem" command to work with Ruby Enterprise Edition's Gems instead of Ruby 1.8 (default)
#
#   Be sure to read the USAGE and NOTICE sections below for more information!
#
#
#   USAGE / INSTALLATION
#   
#   Just copy this file, or it's contents to a file on your server and run it.
#   You will get prompted multiple times for confirmation or to make specific choices.
#   All in all, takes only a little while for the whole installation process to complete, and most of it goes automatically.
#
#   == process ==
#   SSH to your remote server and type: "sudo nano installer.sh"
#   Copy the content of this file into the nano editor and save it
#   This should create a file on the server called installer.sh
#   To execute this, simply type: "sh installer.sh"
#   
#   The installer will now run and install everything for your.
#   You will be prompted only a few times during the process.
#   Just follow the instructions during the installation and go with any "default" settings that get prompted.
#   Select "1" when you get prompted with the option to either let Phusion Passenger Download, Compile and Install NginX or when you want to do it manually.
#   This script insists you let Phusion Passenger handle it. Also let Phusion Passenger install Ruby Enterprise Edition into the /opt/ directory, (which is default, just hit enter on prompt).
#
#
#   NOTICE
# 
#   Ruby 1.8's gems will be available under "rgem" (rubygem). So to install a gem for Ruby 1.8 you'd use: "rgem install [gem-name]"
#   Ruby Enterprise Edition's gems will be available under "gem list" (RubyEnterpriseEditionGem). To install a gem for REE you'd use: "gem install [gem-name]"
#
#   This installer was written for Ubuntu Server Edition 8.04 / 9.04
#
#
#   INFO
#
#   The purpose of this Rails Stack setup is to enable FASTER request handling, a LOT less memory consumption than for example Apache2 and Ruby1.8, very LIGHTWEIGHT and more.
