Docker下RabbitMq集群安装

Docker下RabbitMq集群的安装

本次我们基于docker来搭建rabbitmq的集群环境，我们使用三个rabbitmq服务来搭建集群环境，分别对应到宿主机器的5000、5001、5002端口。

在宿主机创建好文件目录

在宿主机创建rabbitmq5000、rabbitmq5001、rabbitmq5002三个目录。

编排容器

编写如下内容的docker-compose.yaml文件：

version: '2'
services:
  rabbitmq5000:
    image: daocloud.io/library/rabbitmq:3-management
    hostname: rabbit1
    container_name: rabbit1
    ports:
      - "5000:15672"
      - "56720:5672"
    restart: always
    environment:
      - RABBITMQ_NODENAME=rabbit1
      - RABBITMQ_ERLANG_COOKIE=rabbitmqCookie
      - RABBITMQ_DEFAULT_USER=myuser
      - RABBITMQ_DEFAULT_PASS=mypass
    volumes:
      - /data/rabbitmq/rabbitmq5000:/var/lib/rabbitmq
    tty: true
    networks:
      mqnetwork:
        ipv4_address: 172.21.0.2
  rabbitmq5001:
    image: daocloud.io/library/rabbitmq:3-management
    hostname: rabbit2
    container_name: rabbit2
    ports:
      - "5001:15672"
      - "56721:5672"
    restart: always
    environment:
      - RABBITMQ_NODENAME=rabbit2
      - RABBITMQ_ERLANG_COOKIE=rabbitmqCookie
      - RABBITMQ_DEFAULT_USER=myuser
      - RABBITMQ_DEFAULT_PASS=mypass
    volumes:
      - /data/rabbitmq/rabbitmq5001:/var/lib/rabbitmq
      - /data/rabbitmq/rabbitmq-disk.sh:/home/rabbitmq.sh
    links:
      - rabbitmq5000:rabbitmq5000
    tty: true
    networks:
      mqnetwork:
        ipv4_address: 172.21.0.3
  rabbitmq5002:
    image: daocloud.io/library/rabbitmq:3-management
    hostname: rabbit3
    container_name: rabbit3
    ports:
      - "5002:15672"
      - "56722:5672"
    restart: always
    environment:
      - RABBITMQ_NODENAME=rabbit3
      - RABBITMQ_ERLANG_COOKIE=rabbitmqCookie
      - RABBITMQ_DEFAULT_USER=myuser
      - RABBITMQ_DEFAULT_PASS=mypass
    volumes:
      - /data/rabbitmq/rabbitmq5002:/var/lib/rabbitmq
      - /data/rabbitmq/rabbitmq-disk.sh:/home/rabbitmq.sh
    links:
      - rabbitmq5000:rabbitmq5000
    tty: true
    networks:
      mqnetwork:
        ipv4_address: 172.21.0.4


networks:
   mqnetwork:
     ipam:
       config:
       - subnet: 172.21.0.0/16
         gateway: 172.21.0.1

启动容器并配置集群

rabbitmq-disk.sh

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster rabbit1@rabbit1
rabbitmqctl start_app

rabbitmq-ram.sh

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster --ram rabbit1@rabbit1
rabbitmqctl start_app

分别进入5001和5002对应的容器（docker-compose exec container_name bash），根据需要执行相应的集群配置命令即可完成集群配置。

集群验证

访问界面看到如下三个节点代表集群完成
