我在CentOS 7.4.1708服务器上运行rabbitmq-server-3.6.6-1.el7.noarch。 ext4 lvm分区上的/ var / lib /目录存储问题不足，需要我们在线扩展lvm，以便腾出更多空间。
这似乎解决了当时的问题，但需要重启rabbitmq-server服务，当尝试挂起时。 该服务从未启动过。 为了让rabbitmq再次运行，我们备份了旧的mnesia目录，并创建了一个新目录。
为了恢复破损服务中的消息，我已将旧的mnesia移动到新服务器，在新服务器上添加NODENAME=rabbit@oldserver到/etc/rabbitmq/rabbitmq-env.conf并尝试启动它，但它保持不变未能开始。
请问如何在新主机上启动旧的rabbitmq数据库？
[root@newserver]# cat /etc/rabbitmq/rabbitmq-env.conf
NODENAME=rabbit@oldserver
当我尝试在新服务器上启动服务时：
[root@newserver rabbitmq]# systemctl status rabbitmq-server.service -l
? rabbitmq-server.service - RabbitMQ broker
