乘客还是..？ PhusionPassenger::ClassicRails::ApplicationSpawner 中的异常 RuntimeError

Question

昨天我需要在 Debian 6 上重启生产服务器，正常运行时间超过 3 年，并且上面有第 3 方配置的计费系统。我们没有得到那家公司的支持，也不会得到任何支持，因为 "reasons".

据我了解，自配置完成以来，服务器从未重新启动过。此后，计费的 Web 界面在成功登录后显示 500 Internal Server Error。

我不知道该怎么办，检查了所有 oracle、计费系统和 apache 日志。现在我认为我定位了问题，apache 日志说：

有趣的事情：

我根本找不到系统中安装的 gems 或 ruby。当我尝试安装，apt-get 显示需要升级的包太多，所以
我害怕做得更糟。
环境。重新启动后 PATH 丢失，所以我无法调用基本实用程序，因为其中没有 /usr/bin、/usr/sbin、/bin、/sbin 目录。

所以。我有麻烦了。需要帮助。

Answer 1

一些非常基本的东西：

看起来 rvm 用于安装 ruby。（您可以通过堆栈跟踪路径中的 rvm 判断）
Bundler 失败并显示错误消息 Bundler couldn't find some gems. Did you run 'bundle install'?。你运行捆绑安装了吗？您可能需要从 /opt/hydra/rails/ 目录执行此操作，以便 rvm 设置必要的环境变量，以便 bundler 可以找到 hydra 的 Gemfile。
是否正在使用 bundle exec 启动 Rails 服务器？这将确保捆绑器可以在 rails 服务器启动时包含 Gemfile 中的 gem。
您可能没有使用正确的 gemset。从堆栈跟踪来看，似乎正在使用 global。您有什么办法可以确定这是否是要使用的正确宝石集？你可以运行:
```
rvm gemset list
```
显示机器上的 gemsets。也许有一个叫做 hydra 之类的东西？您可以 select 使用不同的 gemset：
```
rvm gemset use <gemset name>
```

抱歉，我无法提供更多帮助。这些是您可以在没有 Ruby 或没有宝石的情况下结束的方法，以及可能的修复方法。除此之外，很难从提供的信息中分辨出来。

希望对您有所帮助！
