尝试使用rabbit@localhost 设置rabbitmq，但是：
c:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.18\sbin>rabbitmqctl status
Error: unable to perform an operation on node 'rabbit@localhost'. Please see diagnostics information and suggestions below.
Erlang + Rabbitmq + Win7。我已经启动了 Rabbitmq 服务，它可以工作，但是节点是使用随机名称自动创建的
