@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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/apple/.ssh/known_hosts to get rid of this message.
Offending RSA key in /Users/apple/.ssh/known_hosts:17
RSA 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
