我使用的是Ubuntu Precision32，并切换到14.04。我使用Jeffrey Way的设置(https://github.com/JeffreyWay/Vagrant-Setup)，并且可以正常工作。我可以执行“vagrant ssh”并登录，然后使用用户名/密码root / root登录到root。

当我尝试将Sequel Pro用于GUI时，出现以下错误:

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 
9d:7c:86:00:20:5a:ca:ef:a0:8a:01:c6:ad:34:cf:de. 
Please contact your system administrator. 
Add correct host key in /Users/chrisfarrugia/.ssh/known_hosts to get rid of this message. 
Offending RSA key in /Users/chrisfarrugia/.ssh/known_hosts:1 
RSA host key for [127.0.0.1]:2222 has changed and you have requested strict checking.

请您参考如下方法:

我找到了答案。我必须为127.0.0.1删除我的known_hosts文件中已经存在的条目，然后该条目才能工作。

该文件位于〜/ .ssh / known_hosts
