ssh连接服务器出错

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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 a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is

Please contact your system administrator.
Add correct host key in /用户home目录/.ssh/known_hosts to get rid of this message.
Offending RSA key in /用户home目录/.ssh/known_hosts:1
RSA host key for ip地址 has changed and you have requested strict checking.
Host key verification failed.

出现这个问题的原因是,第一次使用SSH连接时，会生成一个认证，储存在客户端的known_hosts中.

可使用以下指令查看:

ssh-keygen -l -f ~/.ssh/known_hosts

由于服务器重新安装系统了，所以会出现以上错误。 解决办法:

ssh-keygen -R 服务器端的ip地址

或者直接在known_hosts中删除对应ip的行
