配置rabbitmq集群时，报错

unable to connect to epmd (port 4369) on vm-246: nxdomain (non-existing domain)

详细报错内容
[root@vm-247 ~]# rabbitmqctl join_cluster rabbit@vm-246

Clustering node rabbit@vm-247 with rabbit@vm-246
Error: unable to perform an operation on node 'rabbit@vm-246'. Please see diagnostics information and suggestions below.

Most common reasons for this are:

 * Target node is unreachable (e.g. due to hostname resolution, TCP connection or firewall issues)
 * CLI tool fails to authenticate with the server (e.g. due to CLI tool's Erlang cookie not matching that of the server)
 * Target node is not running

In addition to the diagnostics info below:

 * See the CLI, clustering and networking guides on https://rabbitmq.com/documentation.html to learn more
 * Consult server logs on node rabbit@vm-246
 * If target node is configured to use long node names, don't forget to use --long
