【问题描述】：

我有一个 django 应用程序位于

/home/user/myapp

我正在尝试使用 apache2 和 WSGI 运行该应用程序。目前，apache2 的配置在 /etc/apache2/apache2.conf 并且这个目录与我的网站有关

    <VirtualHost website.com:80>
   ServerName website.com
   ServerAlias www.website.com
   ServerAdmin email@website.com

   DocumentRoot /home/user/myapp/static

   WSGIScriptAlias / /var/www/website-directory/django.wsgi
   <Directory /home/user/myapp/static>
  Order allow,deny
      Allow from all
   </Directory>

   Alias /robots.txt /var/www/webisite-directory/robots.txt
   Alias /favicon.ico /var/www/webisite-directory/favicon.ico
   Alias /images /home/user/myapp/images
   Alias /static /home/user/myapp/static

   ErrorLog /var/www/webisite-directory/error.log
   CustomLog /var/www/webisite-directory/access.log combined
</VirtualHost>

我的 django.wsgi 是

import os
import sys

sys.path.append('/home/user/myapp')

os.environ['DJANGO_SETTINGS_MODULE'] = '/myapp_directory/settings'
sys.executable = '/usr/lib/python2.7/dist-packages'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

这是我的错误日志

【问题讨论】：

标签： python django apache mod-wsgi

【解决方案1】：

DJANGO_SETTINGS_MODULE 应该是一个模块，顾名思义，而不是路径。

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp_directory.settings'

【讨论】：

感谢您的帮助，现在来弄清楚为什么应用程序还没有加载。
很可能是因为您没有告诉 mod_wsgi 您的项目在哪里进行导入。建议您切换到 mod_wsgi 的守护程序模式，然后使用 python-path 选项到 WSGIDaemonProcess 来说明您的项目代码在哪里。见modwsgi.readthedocs.io/en/develop/user-guides/…
当前的问题是你应该通过调用django.core.wsgi.get_wsgi_application() 来获取application，而不是直接实例化WSGIHandler。
