输入密码就可以连接到远程的 SSH 服务器
如果以前登录过，重装服务器后会提示如下错误：

@ 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 the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
ea:24:31:8d:03:07:36:db:2f:74:15:5d:58:67:a3:5b.
Please contact your system administrator.
Add correct host key in /var/root/.ssh/known_hosts to get rid of this message.
Offending key in /var/root/.ssh/known_hosts:1
RSA host key for 192.168.1.203 has changed and you have requested strict checking.
Host key verification failed.
只要清除旧的公钥信息就可以了。
2. 解决方法
ssh-keygen -R ip (远程服务器的 IP)
