Answer 1

看來mod_python會引發錯誤。

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

爲了擺脫它，你將使用相同版本的運行需要recompile mod_python，或者作爲一個更快的解決辦法只是remove and reinstall mod_python。

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

你似乎在同時運行mod_passenger和mod_python。所以你可能會使用乘客服務你的Python應用程序。 這是passenger python how-to，你可能也想看看mod_wsgi。

我會申請選擇你想如何服務python應用程序，註釋掉你不需要的模塊並重新啓動apache。
