设置DEBUG = False会导致500错误

一旦我更改DEBUG = False，我的站点将生成500(使用wsgi & manage.py runserver)，并且在Apache错误日志中没有错误信息，当我将DEBUG更改为True时，它将正常运行。

我使用的是Django 1.5和Python 2.7.3 这是Apache访问日志和Apache错误日志中没有任何日志

我知道这是一个非常老的问题，但也许我可以帮助其他人。如果你在设置DEBUG=False后出现了500个错误，你可以在命令行中运行manage.py runserver来查看任何不会出现在任何web错误日志中的错误。

您还必须检查所有地方的url。当DEBUG被设置为False时，所有没有结尾/的url都被视为bug，不像你设置DEBUG = True时，Django会在所有缺少/的地方添加/。因此，简而言之，确保所有链接都以斜杠“EVERYWHERE”结束。

如果您想允许所有主机。使用ALLOWED_HOSTS = ['*'，] 而不是 Allowed_hosts = ['*']

我认为也可能是http服务器设置。我的仍然是坏的，并有ALLOWED_HOSTS整个时间。我可以在本地访问它(我使用gunicorn)，但不是通过域名时DEBUG=False。当我尝试使用域名，然后给我的错误，所以让我认为这是一个nginx相关的问题。

下面是nginx的conf文件:

server {
    listen   80;
    server_name localhost myproject.ca www.myproject.ca;
    root /var/web/myproject/deli_cms;

    # serve directly - analogous for static/staticfiles
    location /media/ {
        # if asset versioning is used
        if ($query_string) {
            expires max;
        }
    }
    location /admin/media/ {
        # this changes depending on your python version
        root /var/web/myproject/lib/python2.6/site-packages/django/contrib;
    }
    location /static/ {
    alias /var/web/myproject/deli_cms/static_root/;
    }

    location / {
        proxy_pass_header Server;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Scheme $scheme;
        proxy_connect_timeout 10;
        proxy_read_timeout 10;
        proxy_pass http://localhost:8000/;
    }
    # what to serve if upstream is not available or crashes
    error_page 500 502 503 504 /media/50x.html;
}

当执行DEBUG = FALSE时，我也遇到了同样的问题。这里是一个统一的解决方案，分散在上面的答案和其他帖子。

默认情况下，在settings.py中我们有ALLOWED_HOSTS =[]。以下是你必须在ALLOWED_HOSTS值中做出的可能的改变，以消除错误:

1:您的域名:

ALLOWED_HOSTS = ['www.example.com'] # Your domain name here

2:你部署的服务器IP，如果你还没有域名(这是我的情况，工作就像一个魅力):

ALLOWED_HOSTS = ['123.123.198.123'] # Enter your IP here

3:如果你在本地服务器上测试，你可以编辑你的settings.py或settings_local.py为:

ALLOWED_HOSTS = ['localhost', '127.0.0.1']

4:你也可以在ALLOWED_HOSTS的值中提供'*'，但出于安全考虑，不建议在生产环境中使用:

ALLOWED_HOSTS = ['*'] # Not recommended in production environment

我也在我的博客上发布了一个详细的解决方案，你可以参考一下。

我有类似的问题，在我的情况下，这是由于有一个评论脚本在正文标签。
