@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
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
d0:00:7c:bc:88:5c:dc:de:89:61:44:30:00:60:f9:b2.
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 192.168.4.222 has changed and you have requested strict checking.
Host key verification failed.
解决办法：
先cat一下家目录的.ssh/know_hosts
cat ~/.ssh/known_hosts
