WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

今天早上同步另一台服务器上的数据时，因为那台服务器刚重装过了,再执行

rsync -auvb -e ssh root@192.168.4.222:/home home

报错，错误信息如下:
[root@newbiizchina backup_222]# rsync -auvb -e ssh home

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
d0:00:7c:bc:88:5c:dc:de:89:61:44:30:00:60:f9:b2.
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:1
RSA host key for 192.168.4.222 has changed and you have requested strict checking.
Host key verification failed.
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(463) [receiver=2.6.8]

搜索得到如下解决：

因为在本地机器上曾经用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.

vi ~/.ssh/known_hosts

进入此目录，删除192.168.4.222的相关rsa的信息即可.
