服务器重装ip未更改,ssh连不上

前言

重装了虚拟机，ip还保留了，但是发现连不上了

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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:+fniGCBsOCVoDRcIJrBc5x46D13paqRLuQwNDF5zECY.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /root/.ssh/known_hosts:1
ECDSA host key for 192.168.56.203 has changed and you have requested strict checking.
Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

原因

当远程系统上的主机密钥发生更改时，或者因为它们是手动重新生成的，或者因为重新安装了ssh，新的主机密钥将与用户已知主机文件中存储的密钥不匹配，ssh将报告错误，然后退出。

解决方法

如果确定是重装服务器造成的，把当前ip的密匙删除就好了

# ssh-keygen -R 192.168.56.203
