错误：RSA host key for [ip address] has changed and you have requested strict checking.（已解决）

在服务器重装后想要远程连接服务器，报错如下：

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@    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 isSHA256:＊＊＊＊＊＊＊Please contact your system administrator.Add correct host key in /Users/apple/.ssh/known_hosts to get rid of this message.Offending RSA key in /Users/apple/.ssh/known_hosts:17RSA host key for [***ip address***] has changed and you have requested strict checking.Host key verification failed.

因为重装后，本地机和服务器内部ssh对不上导致错误，因此，只需要删除本地机ssh缓存信息，即可恢复。
在本地机输入一下命令行：

ssh-keygen -R [服务器ip address]

得到以下结果：

# Host ［IP address］ found: line **/Users/apple/.ssh/known_hosts updated.Original contents retained as /Users/apple/.ssh/known_hosts.old
