1.下载rabbitmq镜像

docker run -d --hostname rabbit1 --name myrabbit1 -p 15672:15672 -p 5672:5672 -e RABBITMQ_ERLANG_COOKIE='rabbitcookie' rabbitmq:3.7
docker run -d --hostname rabbit2 --name myrabbit2 -p 5673:5672 --link myrabbit1:rabbit1 -e RABBITMQ_ERLANG_COOKIE='rabbitcookie' rabbitmq:3.7
docker run -d --hostname rabbit3 --name myrabbit3 -p 5674:5672 --link myrabbit1:rabbit1 --link myrabbit2:rabbit2 -e RABBITMQ_ERLANG_COOKIE='rabbitcookie' rabbitmq:3.7

2.配置集群

设置节点一
docker exec -it myrabbit1 bash
root@rabbit1:/# rabbitmqctl stop_app
Stopping rabbit application on node rabbit@rabbit1
root@rabbit1:/# rabbitmqctl reset
Resetting node rabbit@rabbit1
root@rabbit1:/# rabbitmqctl start_app
Starting node rabbit@rabbit1
设置节点2，加入到集群：
[root@node03 ~]# docker exec -it myrabbit2 bash
root@rabbit2:/# rabbitmqctl stop_app
Stopping rabbit application on node rabbit@rabbit2
root@rabbit2:/# rabbitmqctl reset
Resetting node rabbit@rabbit2
root@rabbit2:/# rabbitmqctl join_cluster --ram rabbit@rabbit1
Clustering node rabbit@rabbit2 with rabbit@rabbit1
root@rabbit2:/# rabbitmqctl start_app
Starting node rabbit@rabbit2
root@rabbit2:/# exit
参数"--ram"表示设置为内存节点，忽略次参数默认为磁盘节点。
设置节点3，加入到集群：

    docker exec -it myrabbit3 bash
    rabbitmqctl stop_app
    rabbitmqctl reset
    rabbitmqctl join_cluster --ram rabbit@rabbit1
    rabbitmqctl start_app
    exit

3.测试搭建结果

4.配置相同Erlang Cookie

查找Erlang Cookie的位置

docker logs myrabbit3

=INFO REPORT==== 7-Mar-2019::08:25:04 ===
node           : rabbit@rabbit3
home dir       : /var/lib/rabbitmq    ##这个目录下面

root@rabbit3:/# cat /var/lib/rabbitmq/.erlang.cookie 
rabbitcookie

复制容器里的文件到本地
 docker cp myrabbit2:/var/lib/rabbitmq/.erlang.cookie  .
