我昨天使用 PuPHPet 设置了 Vagrant，一切似乎都运行良好。我使用 Querious 连接到 mysql 数据库。但是，我没有保存我用来连接的配置，并且在今天早上做 vagrant up 之后，无论我做什么，我似乎都无法连接。
我正在尝试什么：
- SSH 主机：192.168.56.101
- SSH 用户：vagrant
- SSH 通行证：vagrant
- SSH 密钥：.../puphpet/files/dot/ssh/id_rsa
- SSH 端口 2222
- 主机：127.0.0.1
- 用户：用户名
- 密码：密码
- 端口：3306
如果我尝试这些设置，我会得到
> SSH failed to connect to the server 192.168.56.101 on port 2222
>
> SSH connection failed for an unknown reason. SSH shutdown.

如果我将 SSH 主机更改为 127.0.0.1，我会得到一个不同的错误。远程主机的 SSH 密钥验证失败。

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
9c:3a:9a:d0:22:8c:19:05:f2:26:54:d9:62:9e:ba:e4.
Please contact your system administrator.
Add correct host key in /Users/db/.ssh/known_hosts to get rid of this message.
Offending RSA key in /Users/db/.ssh/known_hosts:2
RSA host key for [127.0.0.1]:2222 has changed and you have requested strict checking.
Host key verification failed.
我做了“vagrant ssh”并转到 ~/.ssh 并且有三个文件，授权密钥、id_rsa 和 id_rsa.pub。id_rsa 与我选择的密钥匹配，但我没有立即识别出 authorized_keys 文件中的内容。
我还尝试使用 Sequel Pro 更改 php.ini a la Connect to MySQL on Vagrant 实例中的绑定地址，但我没有任何运气/不明白这是在做什么。
我显然是在盲目飞行，对 Vagrant 不熟悉，对 SSH 的掌握非常不完整。我接下来应该尝试什么类型的东西才能使它正常工作？
谢谢你。
