Initial publishing of Puppet scripts
April 24, 2012
Once you get to a certain number of servers (virtual, physical, or cloud), you need some manner of centrally managing the machines. Something that will let you install packages and configure them all in some standard way, so you don’t have repeat these steps a hundred times yourself. In my experience, the pay off was less during the initial setup phase (because you’re generally only setting up 1 or 2 machines at a time) and more in the “we need to change something that affects all the machine” phase. Regardless of what phase, Puppet does a great job of helping you out. The last company I worked for did not have much in the way of central management so I started to learn Puppet and deployed it.
Puppet Quick Tip: Enabling an Apache module

Recently, I was asked to enable mod_rewrite for Apache on our webservers, which are controlled by the sexy puppet master server. I did a quick google to see if anyone had any recipes published. On the puppet wiki there is a recipe for Apache on Etch, but their module portion installs Apache modules. In the case of mod_rewrite it comes with Apache2 so it doesn’t need to be as complicated as they suggest.

Hell?
