RSA host key has changed 错误

报错信息如下：

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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:***.
Please contact your system administrator.
Add correct host key in /Users/***/.ssh/known_hosts to get rid of this message.
Offending RSA key in /Users/***/.ssh/known_hosts:2

因为在阿里云上更换了一下镜像，所以再次连接时报错，解决方案如下：

ssh-keygen -R IP  

把IP替换成你的真实地址即可。
