1. 基于docker-compose安装Elasticsearch
    2. 创建目录/usr/local/docker/elasticsearch
    3. 在该目录下创建conf、data、plugins目录
    4. 赋予data777的权限：chmod 777 data
    5. 在conf目录下编写elasticsearch.yml配置文件
      1. cluster.name: "elasticsearch"
      2. network.host: 0.0.0.0
      3. http.cors.enabled: true
      4. http.cors.allow-origin: "*"
      5. xpack.security.enabled: false
      6.在elasticsearch目录下创建docker-compose.yml文件
      1. version: '3.1'
      2. services:
      3. elasticsearch:
      4.  image: elasticsearch:7.6.2
      5.  container_name: elasticsearch
      6.  environment:
      7.    - node.name=node1
      8.    - cluster.initial_master_nodes=node1
      9.    - bootstrap.memory_lock=true
      10.    - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      11.  ulimits:
      12.    memlock:
      13.      soft: -1
      14.      hard: -1
      15.  volumes:
      16.    - ./data:/usr/share/elasticsearch/data
      17.    - ./conf/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
      18.    - ./plugins:/usr/share/elasticsearch/plugins
      19.  ports:
      20.    - 9200:9200
      21.  restart: always
      22.  networks:
      23.    - elastic
      24. kibana:
      25.  image: kibana:7.6.2
      26.  container_name: kibana
      27.  environment:
      28.    - I18N_LOCALE=zh-CN
      29.  ports:
      30.    - 5601:5601
      31.  depends_on:
      32.    - elasticsearch
      33.  restart: always
      34.  networks:
      35.    - elastic
      36. networks:
      37. elastic:
      38.  driver: bridge
      7.修改/etc/sysctl.conf文件：添加vm.max_map_count = 262144到最后一行后保存文件，然后执行命令sysctl -p
      8.启动es和kibana：docker-compose up
      9.测试es：浏览器输入http://虚拟机IP:9200
      10.测试kibana：浏览器输入：http://虚拟机IP:5601
