The LEMP stack is an increasingly popular web service stack, powering mission-critical web services in many production environments. As the name implies, the LEMP stack is composed of Linux, nginx, MariaDB/MySQL and PHP. nginx is a high performance and lightweight replacement of slow and hard-to-scale Apache HTTP server used in the traditional LAMP stack. MariaDB is a community-driven fork of MySQL, with more features and better performance. PHP, a server-side language for generating dynamic content, is processed by PHP-FPM, an enhanced implementation of PHP FastCGI.
In this tutorial, I demonstrate how to set up the LEMP stack on CentOS platforms. I target both CentOS 6 and CentOS 7 platforms, and point out differences where necessary.
