Chef Part 4

Last post I mentioned that one of our nodes is using a recipe we wrote to install Webmin. We have two nodes running, so we decided to run something different on the second one. We wrote an Apache cookbook to install and configure it. Below is our recipe:

# Cookbook Name:: apache2
# Recipe:: default
apt_update 'Update the apt cache daily' do
frequency 86_400
action :periodic

package 'apache2'

service 'apache2' do
supports :status => true
action [:enable, :start]

file '/var/www/html/index.html' do
content '<html>
<h1>hello world</h1>

It’s pretty simple just like the webmin cookbook. Thankfully I didn’t have to use any bash on this one.

The apt_update package just runs

apt-get update


package’apache2′  is basically the same as running

apt-get install apache2


The service resources simply enables and starts the apache 2 service. The file resource changes the content of index.html to be the html that I posted above.

It’s neat that Chef does all of this stuff automatically. It makes it easy to setup an apache web server really quickly.
