RabbitMQ

2019-10-12 Views

简介（天天向上卡索）

RabbitMQ——Rabbit Message Queue的简写，但不能仅仅理解其为消息队列，消息代理更合适。RabbitMQ 是一个由 Erlang 语言开发的AMQP（高级消息队列协议）的开源实现。
RabbitMQ作为一个消息代理，主要和消息打交道，负责接收并转发消息。
RabbitMQ提供了可靠的消息机制、跟踪机制和灵活的消息路由，支持消息集群和分布式部署。适用于排队算法、秒杀活动、消息分发、异步处理、数据同步、处理耗时任务、CQRS等应用场景

docker部署

  • Docker Hub地址
    # --hostname my-rabbit 指定主机名
# -e RABBITMQ_DEFAULT_USER=user -e RABBITMQ_DEFAULT_PASS=password 设置默认的用户名/密码
docker run -tid --hostname my-rabbit --name some-rabbit -e RABBITMQ_DEFAULT_USER=user -e RABBITMQ_DEFAULT_PASS=password rabbitmq

docker部署集群

  • 参考自彭东稳的博客

  • 单机版

    
git clone https://github.com/bijukunjummen/docker-rabbitmq-cluster.git

cd docker-rabbitmq-cluster/cluster  

docker-compose up -d # 如果docker daemon和docker-compose没有安装，要先安装

    • 查看容器，默认启动了3个节点
    docker ps

  • 访问 http://ip:15672，输入guest/guest，进入rabbitmq界面

多机版

假设有三台服务器，IP分别为10.106.136.7，10.106.136.8，10.106.136.9

三台服务器上docker-compose配置文件分别为

  • rabbit1（10.106.136.7）
rabbit1:
  image: bijukunjummen/rabbitmq-server
  hostname: rabbit1
  ports:
    - "5672:5672"
    - "4369:4369"
    - "1883:1883"
    - "15672:15672"
    - "25672:25672"
  environment:
    - RABBITMQ_DEFAULT_USER=myuser
    - RABBITMQ_DEFAULT_PASS=mypass
  • rabbit2（10.106.136.8）
rabbit2:
  image: bijukunjummen/rabbitmq-server
  hostname: rabbit2
  extra_hosts:
    - "rabbit1:10.106.136.7" 
  environment: 
   - CLUSTERED=true
   - CLUSTER_WITH=rabbit1
   - RAM_NODE=true
  ports:
      - "5672:5672"
      - "4369:4369"
      - "1883:1883"
      - "15672:15672"
      - "25672:25672"
  • rabbit3（10.106.136.9）
rabbit3:
  image: bijukunjummen/rabbitmq-server
  hostname: rabbit3
  extra_hosts:
    - "rabbit1:10.106.136.7"
    - "rabbit2:10.106.136.8"
  environment: 
   - CLUSTERED=true
   - CLUSTER_WITH=rabbit1
   - RAM_NODE=true
  ports:
        - "5672:5672"
        - "4369:4369"
        - "1883:1883"
        - "15672:15672"
        - "25672:25672"
  • 依序在三个节点上分别开启rabbitmq，然后随意找个节点打开IP:15672，输入guest用户名和guest密码就可以查看集群了
