IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

Someone could be eavesdropping on you right now (man-in-the-middle attack)!

It is also possible that the RSA host key has just been changed.

The fingerprint for the RSA key sent by the remote host is

60:c3:df:8b:81:f0:d0:62:43:d7:3a:c3:ee:1f:8c:89.

Please contact your system administrator.

Add correct host key in /root/.ssh/known_hosts to get rid of this message.

Offending key in /root/.ssh/known_hosts:1

RSA host key for master has changed and you have requested strict checking.

Host key verification failed.

rm -rf ~/.ssh/known_hosts

重新拷贝就没有问题了。
