You can setup two types of replication in MySQL. First is the master master replication and other one is master slave replication.
But master slave replication provides only load balancing for the databases, it does not provide failover. It means if your master server goes down, you can not execute queries directly on the slave server. In master master replication, it will allows data to be copied from one server to the other. This will adds redundancy and increases efficiency when accessing database.
In this tutorial, we will learn how to configure mysql master master replication between two Ubuntu 16.04 host.

A non-root user with sudo privileges configure on both server.
