准备2台机器，我这里有192.168.0. 和 192.168.0.164

192.168.0.164 作为master

192.168.0.107 作为普通node

.docker 环境

.Elasticsearch5.6.4

.Elasticsearch-head: 插件

docker pull elasticsearch:5.6.

docker pull mobz/elasticsearch-head:

#集群名称 所有节点要相同

cluster.name: "mangues_es"

#本节点名称

node.name: master

#作为master节点

node.master: true

#是否存储数据

node.data: true

# head插件设置

http.cors.enabled: true

http.cors.allow-origin: "*"

#设置可以访问的ip 这里全部设置通过

network.bind_host: 0.0.0.0

#设置节点 访问的地址 设置master所在机器的ip

network.publish_host: 192.168.0.164

docker run -d --name es1 -p : -p : -v /Users/mangues/Desktop/database/Elasticsearch/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /Users/mangues/Desktop/database/Elasticsearch/esdata1:/usr/share/elasticsearch/data elasticsearch:5.6.

cluster.name: "mangues_es"

#子节点名称

node.name: node

#不作为master节点

node.master: false

node.data: true

http.cors.enabled: true

http.cors.allow-origin: "*"

network.bind_host: 0.0.0.0

network.publish_host: 192.168.0.107

#设置master地址

discovery.zen.ping.unicast.hosts: [192.168.0.164]

docker run -d --name es2 -p : -p : -v /Users/mangues/Desktop/database/Elasticsearch/es2.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /Users/mangues/Desktop/database/Elasticsearch/esdata1:/usr/share/elasticsearch/data elasticsearch:5.6.

docker run -p : mobz/elasticsearch-head:

docker run -d -p : --privileged -v /var/run/docker.sock:/var/run/docker.sock uifd/ui-for-docker

elasticsearch max virtual memory areas vm.max_map_count [] is too low

解决办法：

、切换到root用户修改配置sysctl.conf

vi /etc/sysctl.conf 

添加下面配置：

vm.max_map_count=

并执行命令：

sysctl -p

然后，重新启动elasticsearch，即可启动成功。

$ sudo docker exec -it imageId /bin/bash

$ cd plugins

$ wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v5.6.4/elasticsearch-analysis-ik-5.6.4.zip

$ unzip elasticsearch-analysis-ik-5.6..zip

$ rm elasticsearch-analysis-ik-5.6..zip

./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v5.6.4/elasticsearch-analysis-ik-5.6.4.zip
