docker安装 Elasticsearch+Kibana

前提

• 安装了docker，docker-compose，pull了相关的镜像，创建了相关的存放目录
• 本文相关环境如下：

linux:ubuntu:16.04
docker version:19.03.1
docker-compose version:1.24.1
elasticsearch kibana version:7.3.0

docker 安装

docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" --name myEs -d elasticsearch:7.3.0
docker run -p 5601:5601 --name myKb --link myEs -d kibana:7.3.0

docker-compose安装

version: '2.2'
services:
  es01:
    image: elasticsearch:7.3.0
    container_name: es01
    environment:
      - node.name=es01
      - discovery.seed_hosts=es02
      - cluster.initial_master_nodes=es01,es02

    restart: always

        hard: -1
    volumes:
      - ./es02/data:/usr/share/elasticsearch/data
      - ./es02/logs:/usr/share/elasticsearch/logs
    restart: always
    ports:
      - 9201:9200
      - 9301:9300
    networks:
      - esnet
  kibana:
    image: kibana:7.3.0
    container_name: kibana
    environment:
      - server.host=0.0.0.0
      - elasticsearch.hosts=http://es01:9200
      - I18N_LOCALE=zh-CN
      - XPACK_MONITORING_ENABLED=true
    volumes:
      - ./kibana/config/kibana.yml:/usr/share/kibana/config/kibana.yml
    restart: always
    ports:
      - 5601:5601    
    networks:
      - esnet
networks:
  esnet:
    driver: bridge

其中kibana.yml配置如下

server.name: kibana
server.host: "0"
elasticsearch.hosts: [ "http://es01:9200" ]
xpack.monitoring.ui.container.elasticsearch.enabled: true

问题

• 1.es节点挂载目录的权限不够造成容器启动失败，可以执行命令chmod 777 XXX赋予文件权限
• 2.es需要的内存不够可能造成容器未正常启动，可以编辑文件vim /etc/sysctl.conf，在末尾添加vm.max_map_count=262144，最后需要执行命令sysctl -p使配置生效
