1、复制3份ES文件：
2、分别对node1、node2、node3修改config/elasticsearch.yml
node1:
cluster.name: my-application network.host: localhost http.port: 9201 transport.tcp.port: 9301 node.name: node-1 node.master: true node.data: true http.cors.enabled: true http.cors.allow-origin: "*"
node2:
cluster.name: my-application network.host: localhost http.port: 9202 transport.tcp.port: 9302 node.name: node-2 node.master: true node.data: true http.cors.enabled: true http.cors.allow-origin: "*" discovery.seed_hosts: ["localhost:9301"] discovery.zen.fd.ping_timeout: 1m discovery.zen.fd.ping_retries: 5
node3:
cluster.name: my-application network.host: localhost http.port: 9203 transport.tcp.port: 9303 node.name: node-3 node.master: true node.data: true http.cors.enabled: true http.cors.allow-origin: "*" discovery.seed_hosts: ["localhost:9301","localhost:9302"] discovery.zen.fd.ping_timeout: 1m discovery.zen.fd.ping_retries: 5
3、分别启动node1、node2、node3
启动bin/elasticsearch.bat
4、启动完成后，可以查看集群状态：
访问：http://localhost:9201/_cluster/health
{
"cluster_name": "my-application",
"status": "green",
"timed_out": false,
"number_of_nodes": 3,
"number_of_data_nodes": 3,
"active_primary_shards": 2,
"active_shards": 4,
"relocating_shards": 0,
"initializing_shards": 0,
"unassigned_shards": 0,
"delayed_unassigned_shards": 0,
"number_of_pending_tasks": 0,
"number_of_in_flight_fetch": 0,
"task_max_waiting_in_queue_millis": 0,
"active_shards_percent_as_number": 100.0
}
"status": "green",
"number_of_data_nodes": 3,
表示集群配置成功。
