In this tutorial, we will learn how to configure mysql master master replication between two Ubuntu 16.04 host.
Two server running Ubuntu 16.04.
Static IP address 192.168.15.237 configured on first master server.
Static IP address 192.168.15.100 configured on second master server.
A non-root user with sudo privileges configure on both server.
Install and Configure MySQL on First Master Server
