How to install Nginx, PHP5-fpm, MySQL, phpMyAdmin, Postfix on a Ubuntu server using Easy Engine shell script

easyengineIn this tutorial we will show you how to install Nginx, PHP5 (fpm) with Zend OPCache, MySQL, PHPMyadmin, Postfix on an Ubuntu server in less than 20 minutes. We will use Easy Engine for this purpose.

You are probably wondering what is Easy Engine? It is a Linux shell-script to install, manage and host WordPress-Nginx websites on an Ubuntu/Debian server. It works only on a operating system based on Debian because unfortunately there is no support for RPM based systems like CentOS. This script will install Nginx, PHP5-fpm, MySQL, phpMyAdmin and all its dependencies in a single command, thus making it easy for every user that has little experience in working with a Linux VPS.

Nginx is an open source reverse proxy server and can be deployed to serve dynamic HTTP content on the network using FastCGI, SCGI handlers for scripts, WSGI application servers or Phusion Passenger module, and it can serve as a software load balancer. It is a better free alternative to Apache because it is lightweight and RAM-friendly. It also performs better and faster than Apache, particularly when the number of concurrent site visitors is on the rise.

To sum up, Easy Enginge (ee) is built to simplify the process of installing, configuring and managing Nginx (or full LEMP stack to be correct) to host websites on a Ubuntu server. It’s most notable features are:

- Automatically tweaks server configuration as per available hardware resources;
- Supports automatic updates;
- It will install w3-total-cache, wp-super-cache, NGINX’s fastcgi-cache, Zend Opcache, and Memcache;
- Install Nginx, PHP, MySQL, phpMyAdmin and all its dependencies in a single command.
