Metabase 和 Postgresql 之间的 SSH 隧道失败

Question

尝试通过 SSH 隧道在 Metabase 上添加 Postgres 数据库时遇到错误，并显示以下错误消息：“遇到服务器错误” 我的日志与@williamjacksn 在帖子上的日志非常相似：

http://discourse.metabase.com/t/ssh-tunnel-failure/2469

我确信我的凭据没有问题，因为我将相同的凭据用于 Postico SSH 连接以及 DBeaver 连接。

我已经检查了以下修复：https://github.com/metabase/metabase/pull/6970 但是我不知道如何使用它，因为我在我的机器上找不到 ssh.clj 文件。

会有解决办法吗？

额外信息： 通过 .jar 文件安装。使用 Firefox 58.0.2 | Mac OSX 10.10.5

提前致谢

Answer 1

我已经检查了以下修复：https://github.com/metabase/metabase/pull/6970Howerver 我不知道如何使用它，因为我在我的机器上找不到 ssh.clj 文件。

要尝试拉取请求中提出的ssh.clj 更改，您需要从 GitHub 获取源代码，然后从源代码自己构建 Metabase。我只是碰巧在 Metabase 讨论论坛上为处于类似情况的人描述了这些步骤（尽管出于不同目的需要不同的 PR）：
