git操作：WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! （警告:远程主机标识已更改!）

问题背景：

　　前几日，把云服务器系统由centos改成Ubuntu之后，重新搭建的git服务器环境。

问题描述：

　　从本机不能clone远程git仓库。

　　

　　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 is
SHA256:puhqqLAYH9hxo9rEtbhdyoeM98JQsEPY7SKMeNmzt30.
Please contact your system administrator.
Add correct host key in /c/Users/Daemon/.ssh/known_hosts to get rid of this message.
Offending RSA key in /c/Users/Daemon/.ssh/known_hosts:
RSA host key for 118.89.230.188 has changed and you have requested strict checking.
Host key verification failed.

问题解决：

　　把/c/Users/Daemon/.ssh/known_hosts 文件中118.89.230.188地址的公钥删除，更换系统后，需要重新匹配远程服务器信息。
