Clever forks of WP Engine’s Mercury Vagrant for the “roll your own server” types courtesy of Zach Adams.

I say “forks” because he’s actually crafted two different Ansible playbooks. One deploys  WordPress, HHVM, Percona, PHP-FPM & nginx to a server of your choosing while the other adds Varnish, Memcached & APC to the mix.

I have a vested interest in folks signing up for service at WP Engine — seeing as how I work there and all that — but this is still pretty fantastic.
