I decided to take a break from my love affair with Apache and set up a recent development project on Nginx. I’ve seen nothing but good things in terms of speed and performance from Nginx. I decided to set up a LEMP server (Linux, Nginx, MySQL, PHP), minus the MySQL as it’s already installed on my VM host server, and plus SSL. Here’s the full setup tutorial on Debian Wheezy:
