哈喽哇，今天在访问远程服务器的时候，出现了一个小问题。

一、发现问题
问题如下图代码：

$ ssh root@108.61.163.242
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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 is
SHA256:HDjXJvu0VYXWF+SKMZjSGn4FQmg/+w6eV9ljJvIXpx0.
Please contact your system administrator.
Add correct host key in /Users/wangdong/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /Users/wangdong/.ssh/known_hosts:46

一般这个问题，是你重置过你的服务器后。你再次想访问会出现这个问题。

二、解决问题
解决问题也很简单：

ssh-keygen -R 你要访问的IP地址

例如：

ssh-keygen -R 108.61.163.242

好啦。很简单的一个小问题。
搞技术，还是得一点一滴的慢慢积累。不积硅步无以至千里。
