我对 MySQL Workbench 有疑问。我的连接是这样的：
laptop => bastion:22 => machineX:22 (10.10.10.10) => mysql:3306
因此，在到达数据库之前我有两跳（到达数据库本身的三跳）。只有“machineX”可以通过端口 3306 访问该数据库。
我的 SSH 配置包含：
Host 10.10.10.10
ProxyCommand ssh -W %h:%p bastion
使用上面的：
- 我可以通过在本地公开远程端口并连接到本地主机，使用 ssh 隧道成功连接到该数据库
- 我可以在 Mac 上使用 Sequel Pro 成功连接到该数据库（使用 SSH 配置）
但我无法使用 MySQL Workbench 进行连接（使用 TCP/IP over SSH 选项）。尽管我在 MySQL WB 属性中指定了 ssh 配置文件，但它似乎无法弄清楚如何进行这两个跃点。
错误信息：

要么 MySQL Workbench 不够智能，要么还有其他需要设置但我不知道的东西？我尝试了适用于 Mac 和 Windows 的 MySQL WB，但没有成功。正如我所说，例如使用 Sequel Pro 就可以完美地工作！
在你说 - 建立隧道然后在本地主机上连接 - 我已经说不，由于原因我不想这样做。我希望它仅使用 MySQL WB 中的 SSH 配置来工作。
