ElasticSearch集群的搭建

搭建集群

集群规划

# 1.准备3个ES节点和一个kibana 节点  ES 9200 9300 
- web: 9201 tcp:9301  node-1  elasticsearch.yml   
- web: 9202 tcp:9302  node-2  elasticsearch.yml
- web: 9203 tcp:9303  node-3  elasticsearch.yml
- kibana: 5602

注意

• 所有节点集群名称必须一致 cluster.name

• 每个节点必须有一个唯一名字 node.name

• 开启每个节点远程连接 network.host: 0.0.0.0

• 指定使用 IP地址进行集群节点通信 network.publish_host:

• 修改 web 端口 tcp 端口 http.port: transport.tcp.port

• 指定集群中所有节点通信列表 discovery.seed_hosts: node-1 node-2 node-3 相同

• 允许集群初始化 master 节点节点数: cluster.initial_master_nodes: ["node-1", "node-2","node-3"]

• 集群最少几个节点可用 gateway.recover_after_nodes: 2

• 开启每个节点跨域访问http.cors.enabled: true http.cors.allow-origin: "*"
