First up, let’s start with a few cautionary notes. HHVM is not finished. It still doesn’t support absolutely everything that native PHP does (it supports pretty much most of the stuff you should be using, though). If you use some crazy-ass WordPress plugins or some bonkers theme, it may well not be supported. It’s unlikely, but possible.
Second, let me make this absolutely clear; I am not an expert at this sort of stuff. I’m not a sysadmin. I’m not a devops overlord. I’m not a low-level engineer of any kind. I am, however, a guy who enjoys playing with the latest stuff and, after playing with this, I was so blown away by how fast it was, I thought I’d share my experience.
Third, this website – richardtape.com – doesn’t run on this stack just yet. I will be migrating to it fairly soon. Update: This site now runs on this stack. You can read the post about how I migrated from PHP to HHVM. I’ve set up several sites on this stack however, just not this one. I’ll probably write up a separate tutorial for switching from PHP-FPM and nginx to hhvm and nginx in the future.
