Docker—运行ES

一、单节点

1、优化

vim /etc/security/limits.conf
*       soft    nofile  102400
*       hard    nofile  102400
*       soft    nproc  102400
*       hard    nproc  102400

需要退出当前终端，使用命令ulimit -a查看是否生效

2、优化sysctl参数

vim sysctl.conf
   vm.max_map_count = 262144
systctl -p

3、编写docker-compose的配置yaml

创建目录

mkdir esdata
chown -R 1000:1000 esdata

4、无验证

version: '3.8'

services:
  elasticsearch:
    image: xxxxx/library/elasticsearch:9.3.2
    container_name: es
    restart: always
    environment:
      - discovery.type=single-node
      - xpack.security.enabled=false
      - xpack.security.enrollment.enabled=false
      - ES_JAVA_OPTS=-Xms2g -Xmx2g
    ports:
      - "9200:9200"
    volumes:
      - ./es_data:/usr/share/elasticsearch/data
    networks:
      - es_net

  kibana:
    image: xxxx/library/kibana:9.3.2
    container_name: kibana
    restart: always
    environment:
      - ELASTICSEARCH_HOSTS=http://es:9200
    ports:
      - "5601:5601"
    depends_on:
      - elasticsearch
    networks:
      - es_net

networks:
  es_net:

执行命令，创建docker

docker-compose -f es-compose.yaml up -d

5、带验证

version: '3.8'

services:
  elasticsearch:
    image: xxxx/library/elasticsearch:9.3.4
    container_name: es
    restart: always

    environment:
      - discovery.type=single-node

      # 开启安全认证
      - xpack.security.enabled=true
      - xpack.security.enrollment.enabled=true

      # 设置 elastic 超级管理员密码
      - ELASTIC_PASSWORD=Fintech@988.

      - ES_JAVA_OPTS=-Xms2g -Xmx2g

    ports:
      - "9200:9200"

    volumes:
      - /data/dockers_data/esdata:/usr/share/elasticsearch/data

  kibana:
    image: xxxx/library/kibana:9.3.4
    container_name: kibana
    restart: always

    environment:
      - ELASTICSEARCH_HOSTS=http://es:9200

      # Kibana 连接 ES 的账号密码
      - ELASTICSEARCH_USERNAME=kibana_system
      - ELASTICSEARCH_PASSWORD=Es@988.

    ports:
      - "5601:5601"

    depends_on:
      - elasticsearch

注意：es中设置的超级管理员elastic的密码，下面kibana连接es的时候不允许使用elastic账号，因为elastic的账号权限远远大于kibana_system。因此，需要等es启动后需要进入容器修改kubana_system的密码。

docker exec -it es /bin/bash

#执行如下命令（一定要等es启动成功后运行）
/usr/share/elasticsearch/bin/elasticsearch-reset-password -i -u kibana_system

6、打开kibana

http://localhost:5601/

使用elastic用户名及Fintech@988.密码登录
