1、添加端口映射

• 1883 是mqtt tcp协议默认端口
• 15675 是web_mqtt ws协议默认端口
•  
•  
• docker-compose.yml 文件内容如下

version: '3'
services:
  rabbitmq:
    image: rabbitmq:management
    container_name: rabbitmq
    restart: always
    ports:
      - 5672:5672
      - 15672:15672
      - 1883:1883 
      - 15675:15675
    environment:
      RABBITMQ_DEFAULT_USER: admin
      RABBITMQ_DEFAULT_PASS: admin
    volumes:
      - /home/zhu/rabbitmq/lib:/var/lib/rabbitmq
      - /home/zhu/rabbitmq/log:/var/log

2、进入rabbitmq容器内部，开启插件

docker exec -it rabbitmq bin/bash
rabbitmq-plugins enable rabbitmq_mqtt
rabbitmq-plugins enable rabbitmq_web_mqtt

重启rabbitmq 

docker-compose restart



docker-compose -f /home/zhu/rabbitmq/docker-compose.yml up -d
