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:这里每个人都不同

Please contact your system administrator.

Add correct host key in /Users/Anan/.ssh/known_hosts to get rid of this message.

Offending RSA key in /Users/Anan/.ssh/known_hosts:1

Host key verification failed.

会出现这些信息是因为,第一次SSH连接时,会生成一个认证,储存在客户端(也就是用SSH连线其他电脑的那个,自己操作的那个)中的known_hosts,但是如果服务器验证过了,认证资讯当然也会更改,服务器端与客户端不同时,就会跳出错误啦~因此,只要把电脑中的认证资讯删除,连线时重新生成,就一切完美啦~要删除很简单,只要在客户端输入一个指令

ssh-keygen -R +输入服务器的IP

接下來再次连接一次,會出現

Are you sure you want to continue connecting (yes/no)?

输入yes,
就完成连接啦!同時,新的认证也生成了
在mac下使用终端连接服务器方式

ssh root@服务器地址
