2. Install rocketmq

1. Prepare the configuration file

1) Create docker-compose.yml

version: '3'
services: 
 # rocket mq name server
  rmqnamesrv:
    image: apache/rocketmq:4.9.4
    restart: always
    container_name: rocket-server
    # environment:
    #   JAVA_OPT_EXT: "-server -Xms64m -Xmx64m -Xmn64m"
    # volumes:
      # 映射本地目录权限一定要设置为 777 权限，否则启动不成功
      # - ../volumes/data/rocket/server/logs:/home/rocketmq/logs
    networks:
      - rocketmq
    ports:
      - 9876:9876
    command: sh mqnamesrv
  # rocket mq broker
  rmqbroker:
    image: apache/rocketmq:4.9.4
    restart: always
    container_name: rocket-broker
    volumes:
      # 映射本地目录权限一定要设置为 777 权限，否则启动不成功
      # - ../volumes/data/rocket/broker/logs:/home/rocketmq/logs
      # - ../volumes/data/rocket/broker/store:/home/rocketmq/store
      - ./config/broker.conf:/opt/rocketmq-4.9.4/conf/broker.conf
    environment:
      - NAMESRV_ADDR=rmqnamesrv:9876
      # - JAVA_OPTS:=-Duser.home=/opt
      - JAVA_OPT_EXT=-server -Xms64m -Xmx64m -Xmn64m
    depends_on:
      - rmqnamesrv
    networks:
      - rocketmq
    ports:
      - 10909:10909
      - 10911:10911
    command: sh mqbroker -c /opt/rocketmq-4.9.4/conf/broker.conf
  # rocket console 这个可以不需要
  rmqdashboard:
    image: apacherocketmq/rocketmq-dashboard:1.0.0
    restart: always
    container_name: rocket-dashboard
    environment:
      - JAVA_OPTS=-Drocketmq.config.namesrvAddr=rmqnamesrv:9876 -Dserver.port=8180 -Drocketmq.config.isVIPChannel=false
      # - JAVA_OPT_EXT=-Xms128m -Xmx128m -Xmn128m
    depends_on:
      - rmqnamesrv
    networks:
      - rocketmq
    ports:
      - 8180:8180
networks: 
  rocketmq:
    driver: bridge

2) Create a directory config in the folder at the same level, and create a file broker.conf in it. The contents of the file are as follows:

brokerClusterName=DefaultCluster
brokerName=broker-a
brokerId=0
deleteWhen=04
fileReservedTime=48
brokerRole=ASYNC_MASTER
flushDiskType=ASYNC_FLUSH
autoCreateTopicEnable=true
autoCreateSubscriptionGroup=true
## 注意：brokerIP1 要设置成自己服务器的ip
brokerIP1=192.168.56.110

Note: brokerIP1 should be set to the ip of its own server

2. Start

The related image will be downloaded automatically during the startup process

docker-compose -f docker-compose.yml up -d

3. stop

docker-compose -f docker-compose.yml down

4. Access

After the startup is successful, enter http://IP address: 8180 in the browser to access the rocketmq console
