MySQL 8.0 Reference Manual  /  ...  /  Deploying Group Replication in Single-Primary Mode

18.2.1 Deploying Group Replication in Single-Primary Mode

Each of the server instances in a group can run on an independent physical machine, or on the same machine. This section explains how to create a replication group with three MySQL Server instances on one physical machine. This means that three data directories are needed, one per server instance, and that you need to configure each instance independently.

Figure 18.4 Group Architecture

Three server instances, S1, S2, and S3, are deployed as an interconnected group, and clients communicate with each of the server instances.

This tutorial explains how to get and deploy MySQL Server with the Group Replication plugin, how to configure each server instance before creating a group, and how to use Performance Schema monitoring to verify that everything is working correctly.
