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
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 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
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]}]}, {alarms,[]}] 再想加入 报错 :/# rabbitmqctl stop_app Stopping rabbit application on node rabbit@rabbitmq02 root@rabbitmq02:/# rabbitmqctl join_cluster rabbit@rabbitmq01 Clustering node rabbit@rabbitmq02 with rabbit@rabbitmq01 Error: unable to connect to node rabbit@rabbitmq02: nodedown DIAGNOSTICS =========== attempted to contact: [rabbit@rabbitmq02] rabbit@rabbitmq02: * connected to epmd (port 4369) on rabbitmq02 * epmd reports node 'rabbit' running on port 25672 * TCP connection succeeded but Erlang distribution failed * Distribution failed unexpectedly while waiting for challenge: {error, closed} current node details: - node name: 'rabbitmq-cli-69@rabbitmq02' - home dir: /var/lib/rabbitmq - cookie hash: /HHYeuND8Y2blMJ8WoOg1g== root@rabbitmq02:/# rabbitmqctl start_app Starting node rabbit@rabbitmq02 Error: unable to connect to node rabbit@rabbitmq02: nodedown DIAGNOSTICS =========== attempted to contact: [rabbit@rabbitmq02] rabbit@rabbitmq02: current node details: - node name: 'rabbitmq-cli-69@rabbitmq02' - home dir: /var/lib/rabbitmq - cookie hash: /HHYeuND8Y2blMJ8WoOg1g== root@rabbitmq02:/# rabbitmqctl start_app Starting node rabbit@rabbitmq02 Error: unable to connect to node rabbit@rabbitmq02: nodedown DIAGNOSTICS =========== attempted to contact: [rabbit@rabbitmq02] rabbit@rabbitmq02: * connected to epmd (port 4369) on rabbitmq02 * epmd reports node 'rabbit' running on port 25672 * TCP connection succeeded but Erlang distribution failed * TCP connection to remote host has timed out.
