Question

我的Flask应用程序在使用Flask服务器进行本地环回时效果很好，但是现在我试图让apache2在我的专用192.168.0.0/24网络（服务器的IP为192.168.0.18）上为该应用程序提供服务。

EDIT3：除了将.wsgi从文档根目录移出之外，我遵循了Dumpleton先生的大部分建议（我计划在正常运行后这样做）。我能够运行hellow world脚本。我的私有LAN上的任何计算机都可以通过服务器的私有IP看到它。但是，当实际尝试使我的网站运行时，将返回404。 /var/log/apache2/error.log中没有错误。我怀疑问题出在我的flaskapp.wsgi脚本中。似乎与用于简单的“ hello world”页面的页面有很大不同。

有什么建议吗？谢谢你堆栈溢出

此信用归Dumpleton先生所有...这对我来说很重要，目的是使flask应用程序在专用LAN上得到服务。

Originally I thought the secret key was not needed in the  .wsgi file and in the file with the routes as well... However I needed the key in both places

如何通过Apache 2和mod_wsgi在Ubuntu上正确提供Flask App？ 404找不到错误
