以前使用 SSH 登录公司服务器，挺好使！但是，今天它罢工了。 像往常一样，在终端输入命令登录服务器： sudo ssh -l root 192.168.0.88 sorry，它提示信息如下： WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! IT IS POSSIBLE THAT SOMEONE IS DOING SO
以前使用 SSH 登录公司服务器，挺好使！但是，今天它罢工了。
像往常一样，在终端输入命令登录服务器：
sudo ssh -l root 192.168.0.88
sorry，它提示信息如下：
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
51:58:c2:b3:d3:7a:e6:bb:20:bd:5b:37:a1:87:cc:de.
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 192.168.0.88 has changed and you have requested strict checking.
Host key verification failed.
Linux 就是好，有了错误它会提示您错误在哪，根据打印信息，我解决了这个问题。
使用超级用户，为了进入 root/ 目录：
su
然后输入超级用户密码，进入/root/目录：
cd /root
查看该目录接下来的所有文件，然后发现.ssh目录，进入即可！
ls -al
cd .ssh/
在该目录接下来有个文件 known_hosts，使用 vim 打开该文件：
vim known_hosts
删除里面的内容即可，一旦你还怕出错，在删除内容之前可以备份！
再次使用 SSH 登录，出现接下来的信息：
The authenticity of host '192.168.0.88 (192.168.0.88)' can't be established.
RSA key fingerprint is 51:58:c2:b3:d3:7a:e6:bb:20:bd:5b:37:a1:87:cc:de.
Are you sure you want to continue connecting (yes/no)?
yes 即可！搞定！
