哈嘍哇，今天在訪問遠端伺服器的時候，出現了一個小問題。
原因：之前ssh聯絡過伺服器，重置伺服器後，再次連線伺服器，就會出這個問題。
一、發現問題
問題如下圖程式碼：
$ ssh [email protected] @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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. The fingerprint for the ECDSA key sent by the remote host is SHA256:HDjXJvu0VYXWF+SKMZjSGn4FQmg/+w6eV9ljJvIXpx0. Please contact your system administrator. Add correct host key in /Users/wangdong/.ssh/known_hosts to get rid of this message. Offending ECDSA key in /Users/wangdong/.ssh/known_hosts:46 ECDSA host key for 108.61.163.242 has changed and you have requested strict checking. Host key verification failed.
這裡面，有一句很關鍵。
ECDSA host key for 108.61.163.242 has changed and you have requested strict checking.
Host key verification failed.
一般這個問題，是你重置過你的伺服器後。你再次想訪問會出現這個問題。
二、解決問題
解決問題也很簡單：
ssh-keygen -R 你要訪問的IP地址
例如：
ssh-keygen -R 108.61.163.242
貼個圖更直觀
