Answer 1

看起来

mod_python

抛出了一个错误。

 [:error] python_init: Python version mismatch, expected '2.7.5+', found '2.7.9'

为了摆脱它，您需要使用与运行时相同的版本重新编译mod_python，或者作为更快的解决方法，只需删除并重新安装mod_python。

$ apt-get update
$ apt-get remove libapache2-mod-python
$ apt-get build-dep libapache2-mod-python

您似乎同时运行

mod_passenger

和

mod_python

。因此，您可以使用 Passenger 来为您的 Python 应用程序提供服务。 这是 passenger python how-to，您可能还想看看 mod_wsgi。

我建议选择你想要如何服务Python应用程序，注释掉你不需要的模块并重新启动apache。
