RabbitMQ报以上错误时是由于当前节点mnesia数据库中记录还在集群之中，但是集群确认为其已经不咋集群中了，解决方案是：
删除当前节点/var/lib/rabbit/mnesia数据库记录确保/var/lib/rabbit/.erlang.cookie中的key和集群中的保持一致rabbitmq-server start -detached启动erlang和rabbitmq服务器rabbitmqctl stop_app停止rabbitmq服务器rabbitmqctl join_cluster rabbit@emily2 加入集群rabbitmqctl start_app启动当前节点rabbitmqGitHub地址：https://github.com/mingyang66/spring-parent
