我对乘客有误。

我在VPS中设置了redmine。当我在 webrick 中运行时，它运行正常。我曾经乘客在 80 端口运行 redmine。

路径：usr/local/apache/conf/httpd.conf

在 apache 的 error_log 中：

我希望。你提出任何修复它的建议。

正如您在日志中看到的，ApplicationSpawner 由于内存不足错误而崩溃。你没有足够的内存。

您可以做几件事：

  • 使用保守派生，这样您就没有 ApplicationSpawner 进程。由于您的池大小只有 2，因此使用 ApplicationSpawner 不会给您带来任何优势。
  • 添加更多交换空间。
  • 升级你的内存。

有同样的问题，我相信它与乘客控制和优化选项有关，例如PassengerMaxPoolSize。您可能需要将其设置为高于 2。我注意到有人第一次在另一台计算机上同步查看我的应用程序时发生了错误。

要快速修复，请尝试进入项目目录并重新捆绑应用程序，bundle install然后重新启动 Web 服务器，sudo service httpd restart这应该会重置乘客。

此外，丢失的config.ru文件会导致相同的错误消息。您可能想查看这里的讨论。

希望我能告诉你为什么会这样，希望有人会。我很想了解我自己的确切问题，以永久修复。
