Apache + Django + WSGI：页面不工作
Apache + Django + WSGI : Page is not working
我不明白为什么我的 Apache 服务器不工作。当我尝试使用 Opera 连接到地址 http://bde.yggdrasil.cafe 时，我收到以下消息 This page isn't working bde.yggdrasil.cafe is currently unable to handle this request. 我不明白为什么。
我在 /etc/httpd/conf/http.conf
中启用 mod_wsgi
这是我在主配置中导入的配置文件：
$ cat /etc/httpd/conf/extra/bdeweb.conf
<VirtualHost *:80>
# This is name based virtual hosting. So place an appropriate server name
# here. Example: django.devsrv.local
ServerName bde.yggdrasil.cafe
ServerAdmin my@email.fr

我做错了什么？
解决方案
我不得不从 WSGIDaemonProcess 中删除 python-home=/usr/bin/python3 并且我更改了进程组的名称。
