MySQL Cluster Manager MySQL Cluster Manager – Architecture and Use MySQL Cluster Manager Architecture MySQL Cluster Manager is implemented as a set of agents – one running on each physical host that will contain MySQL Cluster nodes (processes) to be managed. The administrator connects the regular mysql client to any one of these agents and then the agents each communicate with each other. By default, port 1862 is used to connect to the agents. An example consisting of 4 host machines together with the mysql client running on a laptop is shown in Figure 1. Figure 1: MySQL Cluster Manager Agents running on each host The agents work together to perform operations across the nodes making up the Cluster, each Cluster dealing with its local nodes (those processes running on the same host). For example, if a data node, management node or MySQL Server on host X fail, then the process will be restarted by the agent running on host X. As another example, in the event of an upgrade operation the agents co-operate to ensure that each node is upgraded in the correct sequence, but it is always the local agent that will actually perform the upgrade to a specific node.
