使用Django 1.6在EC2上，django.wsgi 500内部服务器错误 [英] 500 Internal Server Error with Django 1.6 on EC2, django.wsgi
本文介绍了使用Django 1.6在EC2上，django.wsgi 500内部服务器错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我刚刚完成安装（或试图安装）的EC2服务器上的Django 1.6，但我似乎有与django.wsgi麻烦。
I've just finished installing (or attempting to install) Django 1.6 on an EC2 server, but I seem to be having trouble with django.wsgi.
我已经安装的Django 1.6，httpd的，和mod_wsgi的，而我得到的服务器遇到一个内部错误或配置错误，无法完成您的请求。
I've installed Django 1.6, httpd, and mod_wsgi, and I'm getting the "The server encountered an internal error or misconfiguration and was unable to complete your request.
请与服务器管理员联系，根@本地...
Please contact the server administrator, root@localhost..."
我得到我的地方做了一个失误，但我似乎无法分辨出错误日志正在试图告诉我什么。我看到有底部附近一些数据库错误，我还没有得到来设置任何上去过，但肯定是错误以上是来自一个不同的问题？
I get that I've made a misstep somewhere, but I can't seem to make out what the error logs are trying to tell me. I see there are some database errors near the bottom, and I haven't gotten to setting any up yet, but surely the errors above are from a different issue?
下面是从错误日志中最新的：
Here's is the latest from the error log:

我的django.wsgi如下：
My django.wsgi is as follows:
import os,sys
apache_configuration = os.path.dirname(__file__)
project = os.path.dirname(apache_configuration)
workspace = os.path.dirname(project)
sys.path.append(workspace)
sys.path.append('/home/ec2-user/Django-1.6/joshsite/joshsite')
sys.path.append('/home/ec2-user/Django-1.6/joshsite')
os.environ['DJANGO_SETTINGS_MODULE'] = 'joshsite.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
和我添加这到httpd.conf
And I've added this in to the httpd.conf

)
更新： 有时在/，我得到一个404错误：
Update: Sometimes at /, I get a 404 error:
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.
但随后刷新后有时可以追溯到500，仿佛随意选择。
But then after refreshing it sometimes goes back to a 500, almost as if chosen at random.
推荐答案
检查数据库在 settings.py 。看起来像你的发动机是坏的。请尝试更改为：
Check your DATABASE settings in settings.py. Looks like your ENGINE is bad. Try changing to:
'ENGINE': 'django.db.backends.mysql',
如果这还不奏效，请发表您的数据库设置。
If this doesn't work, please post your database settings.
