git错误：WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED

[root@zq hello]# git pull origin master

@ 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
28:24:ac:e6:84:e3:16:26:c0:65:66:d7:51:8f:6a:6c.
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 192.168.1.152 has changed and you have requested strict checking.
Host key verification failed.
fatal: The remote end hung up unexpectedly

原因：远程的系统改变了，那么加密的密钥也改变了，所以本地已经保存的密钥就失效了，需要重新保存密钥，密钥保存的位置在/$HOME/.ssh/known_hosts

解决的方法：删除/$HOME/.ssh/known_hosts文件中的最后一行（我的就一行，直接删掉就行），然后再pull下，重新输入密码就可以了
