I first tried Nginx back in November last year when I entered the world of VPS. The first ride wasn't smooth as I couldn't get php to work with Nginx.
I recently tried installing the Linux Nginx (Often called Engine X) Mysql and PHP, or the LEMP stack, again and this time I finally cracked it. My little experience is recorded here. I also recorded how to install phpmyadmin which is useful if I have to transfer database between servers.
Now I'll have to test out how I could move database across after that I'll decide if LEMP would be better for my use. My sites currently are of low traffic consuming only about 2G per month but I could see this number growing.
