I’ve been using Vagrant for a little over a year know for all of my web projects, with the exception of Meteor based developments. I’ve traditionally rolled my own, but with the Kelly Purkey project I just wrapped up I grabbed VagrantPress from Chad Thompson.
It’s definitely worth taking the time to look at. It’s two command to have an isolated LAMP stack running running with WordPress already installed (assuming you are already using Vagrant). Just
git clone [repo] &
vagrant up, and moments later WordPress is up.
At some point I intend to write a post about running projects with Vagrant, but for now if you use Vagrant and WordPress, VagrantPress is your friend and you should really go give it a look.
