我们正在使用 django web 框架构建我们的应用程序。我们在应用程序中面临着这个非常关键的问题。我们正在尝试使用结构库连接到远程服务器。通常，我们可以从命令行连接到服务器。此外，它在 django 中的内置服务器中运行良好，因为它从命令行运行。命令

fab get_string -H user@10.10.10.10>>django.txt 2>&1

我们将代码部署在 apache 中，应用程序在函数中遇到此命令时会卡住。偶尔我们会得到这些日志

Aborting."

因为它能够终止连接。但在大多数情况下，它会卡住，我们没有任何日志可显示。

然后我们决定将它作为 Windows 服务运行。我们使用了为我们创建服务的附加 python 文件（recipe.py）。我们再次面临与 apache 相同的问题。

您可能想查看您的连接是否由于 ssh 凭据或类似原因而失败。如果您在此处遵循我的建议并详细记录 ssh/paramiko lib，则可以获得更多信息。
