_ Create and run Chef Client Boot Script_

if [ ! -f /usr/bin/chef-client ]; then
  apt-get update
  apt-get install -y ruby ruby1.8-dev build-essential wget libruby-extras libruby1.8-extras

Class Setup on Ubuntu (Student Notes)

Setup a Student Nodes on Ubuntu

ec2-run-instances ami-4a0df923 --instance-type t1.micro --region us-east-1 --key botchagalupe -g default -g tse-demo -n 12

Create a NodeList (From Mac)

instances=""
for i in `knife ec2 server list | grep running | grep tse-demo | awk '{print $2}'`
do
  export instances="$instances $i"
done

Saved Command Version

for i in `knife ec2 server list | grep running | grep tse-demo | awk '{print $2}'`; do export instances="$instances $i"; done

Create a CAPFILE

require 'tempfile'

set(:nodelist) do
  Capistrano::CLI.ui.ask "Node list: "
end unless exists?(:nodelist)

nodelist.split.each do |node|
  role :nodes, node, :ssh_options => {:user => "ubuntu", :keys => "~/chef-repo/.chef/botchagalupe.pem"}
end

task :default do
  pwhash = "$1$xMc08XfL$b4aNqWyrFB3yg3S3oJo2m0"
  sudo "usermod -p '#{pwhash}' ubuntu"
  sudo "sed -i 's/^PasswordAuthentication no$/PasswordAuthentication yes/' /etc/ssh/sshd_config"
  sudo "/etc/init.d/ssh restart"
end

Run the CAPFILE against the nodes

Install Capistrano if not installed

sudo apt-get -y install capistrano

cap default -S nodelist="$instances"
