配置
主节点
```
network.host: 0.0.0.0
http.cors.enabled: true
http.cors.allow-origin: "*"
cluster.name: idcpj_cluster
node.name: idcpj_1
node.master: true
```
子节点
```
http.cors.enabled: true
http.cors.allow-origin: "*"
cluster.name: idcpj_cluster
node.name: idcpj_2
node.master: false
discovery.zen.ping.unicast.hosts: ["127.0.0.1"]
```
## docker-compose 部署

创建并启动服务
```
docker-compose up -d
docker-compose ps
docker-compose logs
```
### 查看集群状态
`curl http://192.168.20.6:9200/_cat/nodes?v`
### 模拟主节点下载,其他节点选举主节点
```
//下线
docker-compose stop elasticsearch_n0
// 上线
docker-compose stop elasticsearch_n0
```
