ElasticSearch-单机多节点部署方式Centos-72

1. 下载ES安装包 wget https://artifacts.elastic.co/...
2. 解压缩 tar -zxvf elasticsearch-7.8.0-linux-x86_64.tar.gz
3. 将解压后的文件夹复制多份（这里复制三份，分别为node1, node2, node3）

4. 分别进入node1, node2, node3中修改配置文件(省略注释掉的信息)
   node1:

   node.name: node-1node.master: truenetwork.host: 0.0.0.0http.port: 9200transport.tcp.port: 9300discovery.seed_hosts: ["127.0.0.1:9300", "127.0.0.1:9310", "127.0.0.1:9320"]cluster.initial_master_nodes: ["node-1"]http.cors.enabled: truehttp.cors.allow-origin: "*"

   node2:

    node.name: node-2 node.master: false network.host: 0.0.0.0 http.port: 9210 transport.tcp.port: 9310 discovery.seed_hosts: ["127.0.0.1:9300", "127.0.0.1:9310", "127.0.0.1:9320"] http.cors.enabled: true http.cors.allow-origin: "*"

   node3:

    node.name: node-3 node.master: false network.host: 0.0.0.0 http.port: 9220 transport.tcp.port: 9320 discovery.seed_hosts: ["127.0.0.1:9300", "127.0.0.1:9310", "127.0.0.1:9320"] http.cors.enabled: true http.cors.allow-origin: "*"

5. 分别执行node1 node2 node2 中 bin/elasticseach 启动三个节点, -d 为后台启动

./bin/elasticseach -d

1. 访问 http://ip:9200/ 即可查看到es实例信息

ps: 节点内相互访问：

http.cors.enabled: truehttp.cors.allow-origin: "*

配置外网访问：

network.host: 0.0.0.0
