In this tutorial, we will show you how to install two WordPress instances on separate virtual servers with Ubuntu 16.04 OS and Apache, PHP and MySQL installed on them, and how to manage them from a single place using the MainWP WordPress plugin. WordPress is one of the most popular free content management systems, written in PHP that allows web developers to build websites for any purpose. The MainWP dashboard plugin will allow you to manage your WordPress websites from one central location and get nearly complete control of all your WordPress based websites from the MainWP Dashboard.
This tutorial was tested and written for an Ubuntu 16.04 VPS, but it should work on any Linux distribution.
