本地連接出現(xiàn)：錯(cuò)誤

omycar111:~ OMyCar$ ssh root@120.79.45.19

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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 a host key has just been changed.

Please contact your system administrator.
Add correct host key in /Users/OMyCar/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /Users/OMyCar/.ssh/known_hosts:39
ECDSA host key for 120.79.45.19 has changed and you have requested strict checking.

解決方案：

比如我的用戶是OMyCar,立即前往編輯/Users/OMyCar/.ssh/下的known_hosts文件

sudo vim  /Users/OMyCar/.ssh/known_hosts

找到120.79.45.19，刪掉就行
