Thu Sep 10 18:33:00 CST 2020  试过了 这个 版本现在的能用 
sed  -i 's!rabbitmq:3.6.10-management!rabbitmq:3.7.26-management-alpine!' docker-compose.yml



git 
cd  /data/apps
git clone https://github.com/evan886/mq.git 
mv  mq/docker-compose-mqcluster/   . && rm  -rf  mq

把你要的在那台机器改为 docker-compose.yml 和改好相关配置 然后删除其它的 


 </pre>

==mq1==
===Note===
<pre>
  如果是 alpine  rabbitmq:3.6.10-management  换成   其它基础不用变,除了进入容器变成 sh 
  sed  -i 's!rabbitmq:3.6.10-management!rabbitmq:3.7.26-management-alpine!' docker-compose.yml

 有一种是 node1 不加别 , node2  add node1  ; node3  add node1 and node2  但是  rabbitmqctl cluster_status 可能看起来有些node alarms是down的 不过通过浏览器的不会   </pre>

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。

=RabbitMQ实现延迟队列(使用delay插件=
<pre>

docker cp rabbitmq_delayed_message_exchange-3.6.6.ez   c77afe9fa73f:/plugins


: 进入docker容器内 docker exec  -t rabbit  bash

8. 执行命令让插件生效: 启动延时插件：
rabbitmq-plugins enable rabbitmq_delayed_message_exchange
</pre>
https://www.jianshu.com/p/197715cea172

=troubleshooting =
<pre>

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 


问题2 
15672 端口不通 也就是web界面打不开 

问题 镜像用了 rabbitmq 而不是rabbitmq-manager

发现过程 web打不开   15672 端口不能 ，而 5672是通的 进入容器发现是ubuntu 而我记得以前是debian呀 问了下sy才知道 他换了，没全用我的，晕死 ，坑自己人啊 

补救办法  开启 rabbitmq-plugins enable rabbitmq_management


crash dump is being written to: erl_crash.dump...sh: echo: I/O error
原来是空间暴了呢


</pre>

https://www.rabbitmq.com/management.html
==RabbitMQ镜像集群脑裂 ==
<pre>

现象：
RabbitMQ GUI上显示

Network partition detected
Mnesia reports that this RabbitMQ cluster has experienced a network partition. There is a risk of losing data. Please read RabbitMQ documentation about network partitions and the possible solutions.


节点3 是挂，以节点1 为准  在 node2  node3 上 分别执行
rabbitmqctl stop_app
rabbitmqctl start_app

就行 
</pre>

==端口在  进入容器  cannot exec in a stopped state: unknown ==
今天是端口在 docker restart   id 都不行，进程也还在的  重启了 docker 服务才行了

==rabbitmq node not running==
<pre>

行情 重启了一下 docker  mq集群就好了 

试过 telnet  15276 有点不太对 一下就跳出来了  

也登录不了容器  一开始还以为是防火墙
