Nodes in a multi-machine cluster can be divided into master nodes and data nodes, using the Zen Discovery (Zen discovery) mechanism in the configuration file to manage different nodes. Zen Discovery is the default discovery mechanism that comes with ES, using multicast to discover other nodes. As soon as you start a new ES node and set the same name as the cluster, the node is added to the cluster.Select 192.168.0.224 this machine as the master node,
