#!/bin/bash

# This script is meant to configure a stack on Ubuntu 9.10
# It installs Apache mpm-worker, a threaded version of Apache that is faster 
# than mpm-prefork, especially for serving small files.
# It also installs PHP as FastCGI, which is better for a couple of reasons:
# * FastCGI processes stay in memory to serve multiple requests.
# * FastCGI is separate form Apache, so Apache doesn't need to load all of PHP 
#     in order to serve static files, as it does with mod_php
# PHP is installed with gd, mcrypt, mhash, imap, ldap, pdo, mysql, sqlite,
# memcache, curl, pspell, tidy
# PEAR is installed and APC is enabled
# memcached is installed
#
# Grab it from the server using something like this command:
# wget --no-check-certificate $HeadURL: https://sol.rockriverstar.com/svn/server_scripts/trunk/spinup_ubuntu910.sh $
