Hi there,

In order to achieve that you would need to setup MySQL replication. That way all queries executed on the main server would be replicated to the rest of the servers that are part of the cluster.

You can follow the steps on how to do that here:

Alternatively, if you don’t want to set up and manage this yourself, you could take advantage of the DigitalOcean Managed Database Clusters:

MySQL replication is a process that allows you to easily maintain multiple copies of a MySQL data by having them copied automatically from a master to a slave database. This can helpful for many reasons including facilating a backup for the data,a way to analyze it without using the main database, or simply as a means to scale out. This tutorial will cover a very simple example of mysql replication—one master will send information to a single slave.
