一、启动单节点

bin/elasticsearch -E node.name=node0 -E cluster.name=elastic -E path.data=node0_data

二、安装插件

bin/elasticsearch-plugin install analysis-icu

三、 查看插件

bin/elasticsearch-plugin install analysis-icu

四、查看安装的插件

GET http://localhost:9200/_cat/plugins?v

五、启动多节点

bin/elasticsearch -E node.name=node0 -E cluster.name=elastic -E path.data=node0_data
bin/elasticsearch -E node.name=node1 -E cluster.name=elastic -E path.data=node1_data
bin/elasticsearch -E node.name=node2 -E cluster.name=elastic -E path.data=node2_data
bin/elasticsearch -E node.name=node3 -E cluster.name=elastic -E path.data=node3_data

六、查看集群

GET http://localhost:9200

七、查看nodes

GET _cat/nodes
GET _cluster/health

八、添加访问密码

1. 编辑elasticsearch.yml

   network.host: 0.0.0.0
   http.port: 9200
   discovery.seed_hosts: ["0.0.0.0"]
   cluster.initial_master_nodes: ["node-1"]
   
   xpack.security.enabled: true
   xpack.license.self_generated.type: basic
   xpack.security.transport.ssl.enabled: true
   

2. 设置es密码
