This allows you to begin Galera Cluster using the services command. What's more, it sets the database server to start out in the course of boot.
It’s a smart idea to set up electronic mail alerts when replication fails so that you can take care of the situation inside of a timely method.
This tutorial outlines how to configure a MySQL instance on a person server for a source database after which configure a MySQL instance on Yet another server to operate as its reproduction. Furthermore, it contains an outline of how MySQL handles replication.
