ElasticSearch 单机多节点部署方式(Centos 7.2)

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-1
   node.master: true
   network.host: 0.0.0.0
   http.port: 9200
   transport.tcp.port: 9300
   discovery.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: true
   http.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: true
http.cors.allow-origin: "*

配置外网访问：

network.host: 0.0.0.0
