**1. 安装环境前提：**  
`docker` 环境  
`docker-compose` 工具

`备注：基础不好的同学请先了解docker相关内容，否则理解上可能有难度`

**2. 创建文件`docker-compose.yml`，然后放入下面的内容**

version: '3'
    services:
      es-master:
        image: elasticsearch:7.1.1
        container_name: es-master
        privileged: true
        environment:
          - cluster.name=elasticsearch-cluster
          - node.name=es-master
          - node.master=true
          - node.data=true
          - bootstrap.memory_lock=true
          #- discovery.seed_hosts=es-node1,es-node2
          - http.cors.enabled=true
          - http.cors.allow-origin=*
          - cluster.initial_master_nodes=es-master,es-node1,es-node2
          - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
          - "discovery.zen.ping.unicast.hosts=es-master,es-node1,es-node2"
          - "discovery.zen.minimum_master_nodes=2"
        ulimits:
          memlock:
            soft: -1
            hard: -1
        volumes:
          - ./es/master/data:/usr/share/elasticsearch/data
          - ./es/master/logs:/usr/share/elasticsearch/logs
        ports:
          - 9200:9200
    
      es-node1:
        image: elasticsearch:7.1.1
        container_name: es-node1
        privileged: true
        environment:
          - cluster.name=elasticsearch-cluster
          - node.name=es-node1
          - node.master=true
          - node.data=true
          - bootstrap.memory_lock=true
          #- discovery.seed_hosts=es-node1,es-node2
          - http.cors.enabled=true
          - http.cors.allow-origin=*
          - cluster.initial_master_nodes=es-master,es-node1,es-node2
          - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
          - "discovery.zen.ping.unicast.hosts=es-master,es-node1,es-node2"
          - "discovery.zen.minimum_master_nodes=2"
        ulimits:
          memlock:
            soft: -1
            hard: -1
        volumes:
          - ./es/node1/data:/usr/share/elasticsearch/data
          - ./es/node1/logs:/usr/share/elasticsearch/logs
        ports:
          - 9201:9200
    
      es-node2:
        image: elasticsearch:7.1.1
        container_name: es-node2
        privileged: true
        environment:
          - cluster.name=elasticsearch-cluster
          - node.name=es-node2
          - node.master=true
          - node.data=true
          - bootstrap.memory_lock=true
          #- discovery.seed_hosts=es-node1,es-node2
          - http.cors.enabled=true
          - http.cors.allow-origin=*
          - cluster.initial_master_nodes=es-master,es-node1,es-node2
          - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
          - "discovery.zen.ping.unicast.hosts=es-master,es-node1,es-node2"
          - "discovery.zen.minimum_master_nodes=2"
        ulimits:
          memlock:
            soft: -1
            hard: -1
        volumes:
          - ./es/node2/data:/usr/share/elasticsearch/data
          - ./es/node2/logs:/usr/share/elasticsearch/logs
        ports:
          - 9202:9200
    
      kibana:
        image: docker.elastic.co/kibana/kibana:7.1.1
        container_name: kibana
        environment:
          - SERVER_NAME=kibana
          - ELASTICSEARCH_HOSTS=http://es-master:9200
          - XPACK_MONITORING_ENABLED=true
        ports:
          - 5601:5601
        depends_on:
          - es-master
    
      es-head:
        image: tobias74/elasticsearch-head:6
        container_name: es-head
        restart: always
        ports:
          - "9100:9100"

**3. 然后在终端中运行如下命令启动各个容器：**

docker-compose up -d es-master es-node1 es-node2 kibana es-head

`备注1：至于为什么要Es结合kibana和es-head使用，这其实是一套通用的解决方案，大家可以根据实际情况进行安装。`  
`备注2：Es对内存空间的要求比较高，有的时候启动比较慢，可以稍等片刻再检查启动效果`

**4. 检查容器的启动情况，输入命令`docker ps`**

如果看到了上面的效果即表示环境已经安装成功！

**5. 与es进行简单交互，查看服务正常运行的情况，下面是正常情况**

**6. 访问es-head查看集群概览，如果9200端口需要能查到如下情况**

**6. 访问kibana**
