How to configure two nodes to connect to same cluster in elasticsearch?
In machine 1:
cluster.name: hello_worldnetwork.host: "hostname_or_ip_1"network.port: 9201discovery.zen.ping.unicast.hosts: ["hostname_or_ip_2:9201"]In machine 2:
cluster.name: hello_worldnetwork.host: "hostname_or_ip_2"network.port: 9201discovery.zen.ping.unicast.hosts: ["hostname_or_ip_1:9201"]- Both cluster name should be same
discovery.zen.ping.unicast.hostsshould point to correct machineaddress with port- Make sure to restart elasticsearch node after editing config file
Look at unicast discovery with host:port. https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery-zen.html
You might also need to be explicit about the transport.tcp.port in your elasticsearch.yml:transport.tcp.port: 9301
