ssh远程主机标识已更改的问题

ssh -p 22 -i /Users/jeremychen/Downloads/***.id ***@ip
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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 RSA key sent by the remote host is
SHA256:c6EWqQ0khYU1XanNpVUh2fmBnI/Vwnf3gnqXwA8s1g0.
Please contact your system administrator.

意思就是告诉你密钥发生了变化，这个时候需要通过ssh-keygen生成密钥对，如下。id_rsa为私钥文件（保存在client），id_rsa.pub为公钥（用于追加到server的用户目录/.ssh/authorized_keys文件中）

ssh-keygen -R 172.16.22.11 #your ip

再进行一遍即可。

ssh -p 22 -i /Users/jeremychen/Downloads/***.id ***@ip
