A MySQL 5.7 Cluster Based on Ubuntu 16.04 LTS – Part 1

A Cluster Scenario

In this example we create the smallest possible MySQL cluster based on four nodes running on three machines. Node 1 will run the cluster management software, Node 2 and Node 3 will serve as dats nodes and Node 4 is the MySQSL API, which runs on the same VM on Node 1.
