一台mq节点在加入集群后退出了， 后面重新加入集群失败， 报如下错误：

![20200606142345827.png][]

原因是： 主机集群认为该节点仍在集群中， 而该节点实际上退出集群了。 导致数据文件日志不一致，而无法加入集群。

解决方法：

rabbitmqctl stop\_app

1： 删除 /var/lib/rabbitmq/mnesia

2:  主节点中将该节点移除集群： rabbitmqctl forget\_cluster\_node rabbit@mq2   (rabbit@mq2 节点名称)

3：rabbitmqctl join\_cluster  --disc  rabbit@mq1       （--disc 是以磁盘方式加入集群， --ram是内存节点）

4： rabbitmqctl start\_app

5： rabbitmqctl set\_policy ha-all "^ha\\." '\{"ha-mode":"all"\}'   (镜像模式。)
