Installing Lighttpd with PHP (PHP-FPM mode) and MySQL or MariaDB on Ubuntu 15.04
Lighttpd is a secure, fast, standards-compliant web server designed for speed-critical environments. This tutorial shows how you can install Lighttpd on an Ubuntu 15.04 server with PHP support (through PHP-FPM) and MySQL. PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites. I use PHP-FPM in this tutorial instead of Lighttpd's spawn-fcgi.
1 Preliminary Note
In this tutorial I use the hostname server1.example.com with the IP address 192.168.1.100. These settings might differ for you, so you have to replace them where appropriate.
