本文翻译自：[Setting DEBUG = False causes 500 Error][Setting DEBUG _ False causes 500 Error]

*Once I change the `DEBUG = False` , my site will generate 500 (using wsgi & manage.py runserver), and there is no error info in Apache error log and it will run normally when I change `debug` to `True` .* **更改`DEBUG = False` ，我的站点将生成500（使用wsgi＆manage.py runserver），并且Apache错误日志中没有错误信息，并且在将`debug`更改为`True`时它将正常运行。**

*I'm using Django 1.5 & Python 2.7.3 here is Apache access log and without any log in apache error log* **我正在使用Django 1.5和Python 2.7.3，这是Apache访问日志，并且在apache错误日志中没有任何日志**

*Django 1.5 introduced the [allowed hosts setting][] that is required for security reasons.* **Django 1.5引入了出于安全原因所需的[允许主机设置][allowed hosts setting] 。** *A settings file created with Django 1.5 has this new section which you need to add:* **使用Django 1.5创建的设置文件具有此新部分，您需要添加该部分：**

# Hosts/domain names that are valid for this site; required if DEBUG is False
    # See https://docs.djangoproject.com/en/1.9/ref/settings/#allowed-hosts
    ALLOWED_HOSTS = []

*Add your host here like `['www.beta800.net']` or `['*']` for a quick test, [but don't use `['*']` for production][but don_t use _ for production] .* **在此处添加您的主机，例如`['www.beta800.net']`或`['*']` ，以进行快速测试， [但请勿将`['*']`用于生产][but don_t use _ for production] 。**

--------------------

*Right, in Django 1.5 if DEBUG = False, configure ALLOWED\_HOSTS, adding domains without the port number.* **正确，在Django 1.5中，如果DEBUG = False，则配置ALLOWED\_HOSTS，添加不带端口号的域。** *example:* **例：**

ALLOWED_HOSTS = ['localhost']

--------------------

*You must also check your URLs all over the place.* **您还必须检查所有地方的URL。** *When the `DEBUG` is set to `False` , all URLs without trailing `/` are treated as a bug, unlike when you have `DEBUG = True` , in which case Django will append `/` everywhere it is missing.* **当`DEBUG`设置为`False` ，所有不带尾部`/` URL都将被视为一个错误，这与当您设置`DEBUG = True` ，在这种情况下，Django将在`/`丢失的所有位置附加`/` 。** *So, in short, make sure all links end with a slash EVERYWHERE.* **因此，简而言之，请确保所有链接均以“。”开头。**

*I have a hilarious story for all.* **我有一个有趣的故事。** *After reaching this page I said "Eureka! I'm saved. That MUST be my problem."* **到达此页面后，我说：“尤里卡！我已保存。那一定是我的问题。”** *So I inserted the required `ALLOWED_HOSTS` list in setting.py and... nothing.* **因此，我在setting.py中插入了所需的`ALLOWED_HOSTS`列表，然后…什么也没有。** *Same old 500 error.* **相同的旧500错误。** *And no, it wasn't for lack of a 404.html file.* **不，不是因为缺少404.html文件。**

*So for 2 days I busied myself with wild theories, such as that it had something to do with serving static files (understand that I am a noob and noobs don't know what they're doing).* **因此，有两天我忙于野蛮的理论，例如它与提供静态文件有关（请理解我是菜鸟，而菜鸟不知道他们在做什么）。**

*So what was it?* **那是什么** *It is now Mr. Moderator that we come to a useful tip.* **现在是主持人先生，我们提供了一个有用的提示。** *Whereas my development Django is version 1.5.something, my production server version is 1.5.something+1... or maybe plus 2. Whatever.* **我的开发Django版本是1.5.something，而我的生产服务器版本是1.5.something + 1 ...或加2。** *And so after I added the `ALLOWED_HOSTS` to the desktop version of settings.py , which lacked what hwjp requested--- a "default value in settings.py, perhaps with an explanatory comment"--- I did the same on the production server with the proper domain for it.* **因此，当我将`ALLOWED_HOSTS`添加到桌面版本的*settings.py时* ，该版本缺少hwjp要求的内容-“ settings.py中的默认值，可能带有解释性注释”-我在生产服务器上做了相同的操作具有适当的域。**

*But I failed to notice that on the production server with the later version of Django there WAS a default value in settings.py with an explanatory comment.* **但是我没有注意到在带有更高版本Django的生产服务器上，settings.py中有一个默认值，带有解释性注释。** *It was well below where I made my entry, out of sight on the monitor.* **在监视器的视线范围内，它远低于我进入的位置。** *And of course the list was empty.* **当然，列表是空的。** *Hence my waste of time.* **因此，我浪费时间。**

*I think it could also be the http server settings.* **我认为也可能是http服务器设置。** *Mine is still broken and had ALLOWED\_HOSTS the entire time.* **我的仍然很破损，整个时间都保持ALLOWED\_HOSTS。** *I can access it locally (i use gunicorn), but not via the domain name when DEBUG=False.* **我可以在本地访问它（我使用gunicorn），但是当DEBUG = False时不能通过域名访问。** *when I try using the domain name it then gives me the error, so makes me think its a nginx related issue.* **当我尝试使用域名时，它给了我错误提示，因此让我认为这是与Nginx相关的问题。**

*Here is my conf file for nginx:* **这是我的nginx的conf文件：**
