#ssh root@ip报错
得到如下输出
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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
07:09:43:25:ab:e1:01:ac:6b:79:11:2c:76:bb:bf:ad.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending key in /root/.ssh/known_hosts:4
RSA host key for 192.58.180.225 has changed and you have requested strict
checking.
Host key verification failed.
搜索得到如下解决：
因为在本地机器上原来用SSH登录过这台远程计算机，因而留下了known_hosts的记录，在远程计算机重新安装系统后不能够通过鉴权。删除~/.ssh/known_hosts中对应此目录，删除192.58.180.213的相关rsa的信息即可的项目，问题获得解决。
