rabbit3执行相同的命令
docker exec -it rabbitmqCluster03 /bin/bash
rabbitmqctl stop_app
rabbitmqctl join_cluster rabbit@rabbitmq01
rabbitmqctl start_app


查询集群状态
rabbitmqctl cluster_status

nginx 配置


#如果是yum nginx  在放在 conf.d/mq.conf
   server {
        listen       80;
        server_name  mq.com;
 

        location / {
            proxy_pass http://10.3.10.141:15672;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           
        }
     }


NOTE  selinux  记得关掉  不然可能是502哦 
#SELinux设置
getenforce   #查看SELINUX工作模式

sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config #禁用SELINUX
 setenforce 0 #临时禁用SELINUX，无需重启
 
 
 SELINUX=enforcing
#此项定义selinux状态。
#enforcing—是强制模式系统受selinux保护。就是你违反了策略，你就无法继续操作下去
#permissive—是提示模式系统不会受到selinux保护，只是收到警告信息。permissive就是Selinux有效，但是即使你违反了策略的话它让你继续操作，但是把你的违反的内容记录下来(警告信息)
#disabled—禁用selinux。

开启镜像模式

troubleshooting


1.docker-compose.yml文件报错
ERROR: The Compose file './docker-compose.yml' is invalid because:
services.rabbitmq.environment.CLUSTERED contains true, which is an invalid type, it should be a string, number, or a null


CLUSTERED: true -->CLUSTERED: 'true'


绑hosts的前进 不要全局FQ  SSR常常坑我们

rabbitmq node not running

 docker exec  -it af1934d27e21 /bin/bash

再想加入 报错

重启 docker 服务  再 如上添加 不过提示 The node is already a member of this cluster  所以应该是重启docker 就好了
