## 前言 ##

本小节我们学习一下使用Docker部署RabbitMQ集群。  
[RabbitMQ Docker Hub][]

*  目录参考
    
        [root@iZ2ze8sm5upgi8z1dcazqeZ rabbitmq]# pwd
        /workspace/rabbitmq
        [root@iZ2ze8sm5upgi8z1dcazqeZ rabbitmq]# tree
        .
        ├── config
        │   └── docker-compose.yml
        ├── data
        │   ├── rabbitmq1
        │   ├── rabbitmq2
        │   └── rabbitmq3
        └── haproxy-etc
            └── haproxy.cfg
 *  拉取rabbitmq镜像
    
        docker pull rabbitmq:3.8-rc-management
    
    > 若不使用Rabbitmq的management功能，可以拉取镜像：rabbitmq:3.8-rc
 *  创建Rabbitmq共享网络
    
        docker network create rabbitmqnet
    
        [root@iZ2ze8sm5upgi8z1dcazqeZ data]# docker network ls
        NETWORK ID          NAME                DRIVER              SCOPE
        203f098f2ed7        bridge              bridge              local
        901ab7f16e18        config_default      bridge              local
        e5878362fd0d        data_default        bridge              local
        e16693f5cfb7        example_default     bridge              local
        54da0f7e3311        host                host                local
        6ad755fc1934        none                null                local
        a4b8c1129340        rabbitmqnet         bridge              local
        [root@iZ2ze8sm5upgi8z1dcazqeZ data]#
 *  创建节点(三个节点)  
    注意这里使用相同的 RABBITMQ\_ERLANG\_COOKIE 值
    
        ```

 *  组建rabbitmq集群  
    登陆Rabbitmq的后两个节点，执行命令加入第一个Rabbitmq节点集群
    
        ### 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 && \

 *  拉取haproxy镜像
    
        docker pull haproxy
 *  创建目录/workspace/rabbitmq/haproxy-etc,并在该路径下创建haprox.cfg配置文件

    haproxy.cfg配置信息如下：

 *  拉取haproxy镜像
    
        docker pull haproxy
 *  启动haproxy
    
        docker run -d \
            --name rabbitmq-haproxy \
            -p 8002:8002 -p 5677:5677 -p 8001:8001 \

            -v /workspace/rabbitmq/haproxy-etc:/usr/local/etc/haproxy:ro \
            haproxy:latest
    
    启动haproxy后，可以通过haproxy来访问rabbitmq集群：http://你的公网IP:8001
