Question

在过去的几天里，我一直在努力使用Bitnami Djangostack在Amazon EC2上部署Django应用程序。当我转到我的主页（说http://example.com）时，我会看到默认的bitnami页面（ /opt/bitnami/apache2/htdocs/index.html ），但是，当我打开{{3}我得到'内部服务器错误'。但是众所周知，如果mod_wsgi设置正确，httpd.conf中的DocumentRoot值将被忽略，因此，我应该在访问http://example.com/portnoy时看到我的Django应用程序。本质上，主要的错误是 - '目标WSGI脚本无法作为Python模块加载'。两个问题：1）任何想法如何解决这些mod_wsgi错误（Apache日志如下）？ 2）如何在访问http://example.com时禁用默认 /opt/bitnami/apache2/htdocs/index.html 页面并从django应用程序显示我的主页？提前谢谢！

让我快速介绍文件的内容，使案例更加具体。

这是我的 / etc / apache2 / sites-available / default 文件

<VirtualHost *:80>

ServerName example.com

这是我的 /opt/bitnami/apps/django/scripts/django.wsgi 文件

import os, sys

sys.path.append('/opt/bitnami/apps/django/lib/python2.7/site-packages/')
sys.path.append('/opt/bitnami/apps/django/django_projects')
sys.path.append('/opt/bitnami/apps/django/django_projects/portnoy')
os.environ['DJANGO_SETTINGS_MODULE'] = 'portnoy.settings'

import django.core.handlers.wsgi

application = django.core.handlers.wsgi.WSGIHandler()

以下是 /opt/bitnami/apache2/conf/httpd.conf 文件的相关部分：

ServerRoot "/opt/bitnami/apache2"
Listen 80
ServerName example.com
DocumentRoot "/opt/bitnami/apache2/htdocs"
LoadModule wsgi_module modules/mod_wsgi.so
WSGIPythonHome /opt/bitnami/python
Include "/opt/bitnami/apache2/conf/ssi.conf"
Include "/opt/bitnami/apps/django/conf/django.conf"
Include "/opt/bitnami/apache2/conf/bitnami/httpd.conf"

注意：我在本文中使用example.com来引用我实际拥有的域名。
