**拉取ES镜像（版本5.5.2）**

**docker pull hub.c.163.com/library/elasticsearch:latest**

**改名**

**docker tag hub.c.163.com/library/elasticsearch elasticsearch**

在/usr/local目录下新建数据挂载目录和配置文件目录

mkdir data1

mkdir data2

mkdir data3

配置目录

mkdir config

cd config/

创建es1

touch es1.yml

vim es1.yml

es1.yml文件

cluster.name: elasticsearch-cluster
    node.name: es-node1
    network.bind_host: 0.0.0.0
    network.publish_host: 192.168.120.128
    http.port: 9200
    transport.tcp.port: 9300
    http.cors.enabled: true
    http.cors.allow-origin: "*"
    node.master: true
    node.data: true
    discovery.zen.ping.unicast.hosts: ["192.168.120.128:9300","192.168.120.128:9301","192.168.120.128:9302"]
    discovery.zen.minimum_master_nodes: 1

es2.yml文件

cluster.name: elasticsearch-cluster
    node.name: es-node2
    network.bind_host: 0.0.0.0
    network.publish_host: 192.168.120.128
    http.port: 9201
    transport.tcp.port: 9301
    http.cors.enabled: true
    http.cors.allow-origin: "*"
    node.master: true
    node.data: true
    discovery.zen.ping.unicast.hosts: ["192.168.120.128:9300","192.168.120.128:9301","192.168.120.128:9302"]
    discovery.zen.minimum_master_nodes: 1

es3.yml文件

cluster.name: elasticsearch-cluster
    node.name: es-node3
    network.bind_host: 0.0.0.0
    network.publish_host: 192.168.120.128
    http.port: 9202
    transport.tcp.port: 9302
    http.cors.enabled: true
    http.cors.allow-origin: "*"

    discovery.zen.minimum_master_nodes: 1

调高jvm线程数限制  
vim /etc/sysctl.conf  
加入  
vm.max\_map\_count=262144
