WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

今天远程ssh登录遇见下边提示：

@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
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
da:f4:a0:89:a6:2b:87:86:69:33:59:ad:eb:da:66:3a.
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:2
RSA host key for 10.8.59.194 has changed and you have requested strict checking.
Host key verification failed.

解决方法：打开文件/root/.ssh/known_hosts ，删除与远程主机有关的信息即可。个人原因是由于远程主机重装了系统。
