SSH无法连接VPS怎么办

ssh命令连接时，出现错误如下：

zhang-hengde-MacBook-Air:~ henry24264$ ssh [email protected]

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@ 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

08:70:a2:d1:8c:a8:e2:a3:75:27:b5:90:ce:54:5b:3d.

Please contact your system administrator.

Add correct host key in /Users/henry/.ssh/known_hosts to get rid of this message.

Offending key in /Users/henry/.ssh/known_hosts:2

RSA host key for 66.105.230.188 has changed and you have requested strict checking.

Host key verification failed.

google之后，找到了解决方案，命令如下，删除相关信息即可，

代码如下
1 zhang-hengde-MacBook-Air:~ henry24264$ vi ~/.ssh/known_hosts

之后会看到如下信息：将下面的ssh-rsa全部删除即可，vi命令后，左右键找到下面信息的位置，然后在选中行处，按dd即可删除一行。
