1. 新建一个`elasticsearch` 文件夹

mkdir elasticsearch
    cd elasticsearch

2. 新建es配置文件

进入elasticsearch目录，新建elasticsearch.yml，写入：

http.host: 0.0.0.0
    xpack.security.enabled: true
    http.cors.enabled: true
    http.cors.allow-origin: "*"

3. 新建数据目录

mkdir data01 data02 data03
    # 设置权限，要不然会报 AccessDeniedException 错
    chmod -R 777 data01 data02 data03

4. 新建 docker-compose.yml

我们创建一个三个节点的es集群，并开启kibana做展示，配置docker-compose.yml 文件如下：

version: "3"
    services:
      es_node01:
        image: elasticsearch:7.10.1
        container_name: es_node01
        environment:
          - node.name=es_node01
          - cluster.name=es-docker-cluster
          - discovery.seed_hosts=es_node02,es_node03
          - cluster.initial_master_nodes=es_node01
          - bootstrap.memory_lock=true
          - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
        ulimits:
          memlock:
            soft: -1
            hard: -1
        volumes:
          - ./data01:/usr/share/elasticsearch/data:cached
          - ./elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml:cached
        ports:
          - 9200:9200
        logging: 
          driver: "json-file"
          options: 
            max-size: "500m"
        networks:
          - dev_network
    
      es_node02:
        image: elasticsearch:7.10.1
        container_name: es_node02
        environment:
          - node.name=es_node02
          - cluster.name=es-docker-cluster
          - discovery.seed_hosts=es_node01,es_node03
          - cluster.initial_master_nodes=es_node01
          - bootstrap.memory_lock=true
          - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
        ulimits:
          memlock:
            soft: -1
            hard: -1
        volumes:
          - ./data02:/usr/share/elasticsearch/data:cached
          - ./elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml:cached
        logging: 
          driver: "json-file"
          options: 
            max-size: "500m"
        networks:
          - dev_network
    
      es_node03:
        image: elasticsearch:7.10.1
        container_name: es_node03
        environment:
          - node.name=es_node03
          - cluster.name=es-docker-cluster
          - discovery.seed_hosts=es_node01,es_node02
          - cluster.initial_master_nodes=es_node01
          - bootstrap.memory_lock=true
          - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
        ulimits:
          memlock:
            soft: -1
            hard: -1
        volumes:
          - ./data03:/usr/share/elasticsearch/data:cached
          - ./elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml:cached
        logging: 
          driver: "json-file"
          options: 
            max-size: "500m"
        networks:
          - dev_network
    
      es_kibana:
        image: kibana:7.10.1
        container_name: es_kibana
        depends_on:
          - es_node01
        ports:
          - 5601:5601
        environment:
          ELASTICSEARCH_URL: http://es_node01:9200
          ELASTICSEARCH_HOSTS: http://es_node01:9200
        volumes:
          - ./kibana.yml:/usr/share/kibana/config/kibana.yml:cached
        logging: 
          driver: "json-file"
          options: 
            max-size: "500m"
        networks:
          - dev_network
    
    # 网络配置
    networks:
      dev_network:
        external:
          name: dev_network

5. 创建网络

docker network create dev_network

6. 执行命令启动

创建容器，启动es服务

docker-compose up -d --build #静默启动
    docker-compose up #控制台启动
    docker-compose down #停止容器
    docker-compose down -v #停止容器并且移除数据

启动比较慢，要多等一会  
查看elasticsearch信息命令：

curl -X GET "localhost:9200/_cat/nodes?v&pretty"

浏览器打开 [http://localhost:5601][http_localhost_5601] 就可以通过界面查看elasticsearch的数据

7. 创建密码

启动完成之后进入es\_node01命令行,执行:

docker exec -it es_node01 /bin/bash
    ./bin/elasticsearch-setup-passwords auto

命令行会输入各种密码，需要找个地方记录下来

打开浏览器，输入127.0.0.1:9200，会提示要密码验证了，输入密码之后就可以显示正确信息了。

8. 配置kibana.yml

写入如下内容

server.host: 0.0.0.0
    elasticsearch.username: kibana
    elasticsearch.password: 上一步生成的kibana密码
    i18n.locale: "zh-CN"

重新创建kibana服务

docker stop es_kibana
    docker rm es_kibana
    docker-compose up -d --build es_kibana

完成之后打开浏览器输入 127.0.0.1:5601 ,输入es的账号密码就可以登录

配置ik分词器

docker exec -it es_node01 /bin/bash
    cd /usr/share/elasticsearch/plugins/
    elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.2.0/elasticsearch-analysis-ik-7.2.0.zip
    exit
    docker restart elasticsearch

可能报错：

1.  权限不足导致报错  
    `[ElasticsearchException[failed to bind service]; nested: AccessDeniedException[/usr/share/elasticsearch/data/nodes]](https://www.cnblogs.com/leozhanggg/p/12390850.html)`  
    解决方法:

修改数据目录
    chmod -R 777 data01 data02 data03

1.  max\_map\_count 设置太低  
    `memory areas vm.max_map_count [65530] is too low, increase to at least [262144]`  
    持久性的做法是在 /etc/sysctl.conf 文件中修改 vm.max\_map\_count 参数  
    vm.max\_map\_count=262144

然后执行

sysctl -w vm.max_map_count=262144

1.  `Cause: Cluster state has not been recovered yet, cannot write to the [null]index`  
    主节点只设置成一个：cluster.initial\_master\_nodes=es\_node01
