WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

原因是系统出现了变故原来的ssh公钥变了导致连接不上。

解决：

ssh-keygen -R 服务器IP地址

(会出现下面提示)
# Host 192.168.200.6 found: line 1
C:\Users\Administrator/.ssh/known_hosts updated.
Original contents retained as C:\Users\Administrator/.ssh/known_hosts.old

再次连接会提示yes/no，输入yes连接成功

ssh root@服务器IP
