SSH链接问题 Host key verification failed

1.当换了主机连接的时候，如果ip地址不一样，连接的时候会报如下的错误:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@    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 isSHA256:X7t3q9KPoEBAjfkxTcMHguxbz9hnP9+cnJro8nRAZTk.Please contact your system administrator.Add correct host key in /Users/rs/.ssh/known_hosts to get rid of this message.Offending ECDSA key in /Users/rs/.ssh/known_hosts:5ECDSA host key for 172.16.36.148 has changed and you have requested strict checking.Host key verification failed.

解决办法:

连接机进入~/.ssh/文件夹 编辑known_hosts文件，删除文件相应地址的错误的密钥文件保存重新连接即可
