Rabbitmq常用命令

docker简易搭建RabbitMQ集群HA-good

ins rabbitmq

info

 适合于 3.610 and 3.7.5 版本
-p 15672:15672 http访问端口
-p 5672:5672 amqp访问端口
-p 4369 #unable to connect to epmd (port 4369) on rabbitmq01: address (cannot connect to host/port)

mq1

Note

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

config

将节点2,3加入集群

#在rabbit2机器进入容器的命令行
sudo docker exec -it rabbitmqCluster02 /bin/bash

#加入集群
rabbitmqctl stop_app
rabbitmqctl join_cluster rabbit@rabbitmq01
rabbitmqctl start_app

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。

镜像模式

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镜像集群脑裂


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

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


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  



 docker exec  -it af1934d27e21 /bin/bash 
root@rabbitmq02:/# rabbitmqctl cluster_status
Cluster status of node rabbit@rabbitmq02
[{nodes,[{disc,[rabbit@rabbitmq01,rabbit@rabbitmq02,rabbit@rabbitmq03]}]},

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
