docker compose部署rabbitmq集群

docker compose 配置

假设有两台电脑
A电脑的ip为192.168.1.100
B电脑的ip为192.168.1.103
A电脑的docker compose 配置

version: '3'

services:

  rabbitmq:
    restart: always
    image: rabbitmq:3.9.18-management
    container_name: rabbitmq-node-1
    hostname: rabbit1
    extra_hosts:
      - "rabbit1:192.168.1.100"
      - "rabbit3:192.168.1.103"
    ports:
      - "4369:4369"
      - "5672:5672"
      - "15672:15672"
      - "25672:25672"
    volumes:
      - rabbitmq_log:/var/log/rabbitmq
      - rabbitmq_data:/var/lib/rabbitmq

volumes:
  rabbitmq_log:
  rabbitmq_data:

B电脑的docker compose 配置

version: '3'

services:

  rabbitmq:
    restart: always
    image: rabbitmq:3.9.18-management
    container_name: rabbitmq-node-3
    hostname: rabbit3
    extra_hosts:
      - "rabbit1:192.168.1.100"
      - "rabbit3:192.168.1.103"
    ports:
      - "4369:4369"
      - "5672:5672"
      - "15672:15672"
      - "25672:25672"
    volumes:
      - rabbitmq_log:/var/log/rabbitmq
      - rabbitmq_data:/var/lib/rabbitmq

volumes:
  rabbitmq_log:
  rabbitmq_data:

两边同时启动

docker compose up -d

拷贝cookie

 scp /var/lib/docker/volumes/root_rabbitmq_data/_data/.erlang.cookie root@192.168.1.103:/var/lib/docker/volumes/root_rabbitmq_data/_data/

ps：/var/lib/docker/volumes/root_rabbitmq_data/ 要根据实际情况进行修改

进入B的rabbitmq

#停止
rabbitmqctl stop_app
#加入
rabbitmqctl join_cluster rabbit@rabbit1
#启动
rabbitmqctl start_app

查看状态

rabbitmqctl cluster_status

返回结果

成功加入集群
