1 Installation Environment Install the multi-machine ES cluster (distributed cluster), install an ES node in three servers respectively, and these three nodes form an ES cluster. Because it is a small cluster, setting these three nodes can be a master node and a data node. The server's IP is 192.168.1.111, 192.168.1.112, and 192.168.1.113, respectively.
