• 创建RabbitMQ集群共享网络

  docker network create rabbitmqnet
  

• docker-compose.yml

  version: '3.7'
  services:
    rabbitmq1:
      image: rabbitmq:3.8-rc-management
      container_name: rabbitmq1
      restart: always
      ports:
          - 5672:5672
          - 15672:15672
      volumes:
        - /workspace/rabbitmq/data/rabbitmq1:/var/lib/rabbitmq:z
      environment:
          RABBITMQ_DEFAULT_USER: 'Dustyone'
          RABBITMQ_DEFAULT_PASS: 'bai5331359'
          RABBITMQ_NODENAME: 'rabbitmq1'
          RABBITMQ_ERLANG_COOKIE: 'Dustyone-Murex-cluster-cookie'
      hostname: rabbitmq1
      
    rabbitmq2:
      image: rabbitmq:3.8-rc-management
      container_name: rabbitmq2
      restart: always
      ports:

        - 15673:15672
      volumes:

          RABBITMQ_DEFAULT_PASS: 'bai5331359'
          RABBITMQ_NODENAME: 'rabbitmq2'
          RABBITMQ_ERLANG_COOKIE: 'Dustyone-Murex-cluster-cookie'
      hostname: rabbitmq2
      links:
      - rabbitmq1
            
    rabbitmq3:
      image: rabbitmq:3.8-rc-management
      container_name: rabbitmq3
      restart: always
      ports:
          - 5674:5672
          - 15674:15672
      volumes:
          - /workspace/rabbitmq/data/rabbitmq3:/var/lib/rabbitmq:z
        
      environment:
          RABBITMQ_DEFAULT_USER: 'Dustyone'
          RABBITMQ_DEFAULT_PASS: 'bai5331359'

          RABBITMQ_ERLANG_COOKIE: 'Dustyone-Murex-cluster-cookie' 
      hostname: rabbitmq3
      links:
      - rabbitmq1
      - rabbitmq2
            
    rabbitmq-haproxy:
      image: haproxy
      container_name: rabbitmq-haproxy
      restart: always
      ports:
        - 8002:8002
        - 5677:5677
        - 8001:8001
      volumes:
        - /workspace/rabbitmq/haproxy-etc:/usr/local/etc/haproxy:ro
      links:
      - rabbitmq1
      - rabbitmq2
      - rabbitmq3
      
  networks:
     default:
      external:
        name: rabbitmqnet
  

• 执行docker-compose.yml

  docker-compose up -d
  

  [root@iZ2ze8sm5upgi8z1dcazqeZ config]# docker ps -a

• 将rabbitmq2和rabbitmq3两个节点加入rabbitmq1节点以形成集群。

  ### Disk Node
  docker exec rabbitmq2 bash -c \
  "rabbitmqctl stop_app && \
  rabbitmqctl reset && \
  rabbitmqctl join_cluster rabbitmq1@rabbitmq1 && \
  rabbitmqctl start_app"
  

  ### Ram Node
  # docker exec rabbitmq3 bash -c \
  "rabbitmqctl stop_app && \
  rabbitmqctl reset && \
  rabbitmqctl join_cluster --ram rabbitmq1@rabbitmq1 && \
  rabbitmqctl start_app"
  

  [root@iZ2ze8sm5upgi8z1dcazqeZ config]# docker exec rabbitmq2 bash -c \
  > "rabbitmqctl stop_app && \
  > rabbitmqctl reset && \
  > rabbitmqctl join_cluster rabbitmq1@rabbitmq1 && \
  > rabbitmqctl start_app"
  Stopping rabbit application on node rabbitmq2@rabbitmq2 ...

   completed with 3 plugins.
  [root@iZ2ze8sm5upgi8z1dcazqeZ config]# docker exec rabbitmq3 bash -c \
  > "rabbitmqctl stop_app && \
  > rabbitmqctl reset && \
  > rabbitmqctl join_cluster --ram rabbitmq1@rabbitmq1 && \
  > rabbitmqctl start_app"
  Stopping rabbit application on node rabbitmq3@rabbitmq3 ...
  Resetting node rabbitmq3@rabbitmq3 ...
  Clustering node rabbitmq3@rabbitmq3 with rabbitmq1@rabbitmq1

• 访问http://你的公网IP:8002
  如此便完成了使用docker-compose部署Rabbitmq集群

• 启动停止Rabbitmq-Cluster建议使用如下Command

  docker-compose up -d
  

  docker-compose stop
  

• 此类方法部署RabbitMQ集群有很多细节，便不一一说明了，挑几个重用的说一下

  • 所有的节点最好共享一个网络块
  • 执行docker-compose.yml之前要创建好所有的配置文件

• 安全组规则
