Python EC2上Django 1.6的500内部服务器错误，Django.wsgi

我刚刚在EC2服务器上完成了Django 1.6的安装（或尝试安装），但我似乎在使用Django.wsgi时遇到了问题

我已经安装了Django 1.6、httpd和mod_wsgi，我得到了“服务器遇到内部错误或配置错误，无法完成您的请求”

请与服务器管理员联系，root@localhost..."

我知道我在某个地方犯了一个错误，但我似乎不明白错误日志试图告诉我什么。我看到底部附近有一些数据库错误，我还没有设置任何错误，但上面的错误肯定是来自另一个问题

以下是错误日志中的最新信息：

我已经将其添加到httpd.conf中

这是我的URL.py：

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'joshsite.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),

    url(r'^admin/', include(admin.site.urls)),
    url(r'^home/', 'joshsite.views.home', name='home'),
)

更新： 有时在/，我会收到一个404错误：

Request Method: GET
Request URL:    http://ec2-54-187-46-240.us-west-2.compute.amazonaws.com/
Using the URLconf defined in joshsite.urls, Django tried these URL patterns, in this order:
^admin/
^home/ [name='home']
The current URL, , didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
Thank you in advance for any assistance.

但在刷新后，它有时会返回到500，几乎就像随机选择的一样。

检查

数据库
设置中的
设置。看起来你的
引擎坏了。尝试更改为：

'ENGINE': 'django.db.backends.mysql',

如果这不起作用，请发布您的数据库设置。
Nice，我重新加载了页面（在/），它变为404，它说使用joshsite.URL中定义的URLconf，Django尝试了这些URL模式。。。未匹配其中任何一个，并且该调试设置为true/在家里，我的成绩仍然是500分。我将使用设置添加新的回复/编辑我的帖子。好的，现在这不是设置问题，而是新问题。我会关闭这一个，并开始一个新的问题与您的新问题。在其中，包括您访问的url、您的
url.py
文件，以及您收到的错误消息的更多详细信息。谢谢，非常感谢。在我将debug设置为false之后，现在这只是一个500错误，所以我想最好重新发布此错误。您的新错误看起来与旧错误相同。您是否错误地回滚了数据库更改？或者粘贴了错误的新错误消息。
