To configure a Cluster, you must at least configure1 MGM (Management node) + 1 SQL node + 2 Data NodeMGM can share a machine with the SQL node, and the data node occupies a server separately.This requires at least three servers.Sometimes it will be very troublesome. In the learning stage, you can consider building a MySQL Cluster on a single server.The following
