python - 新手对 mod_wsgi/apache/django 设置感到困惑

Question

这是我关于 SO 的第一篇文章。我已经变得太沮丧，无法继续研究这个问题，所以我只是发布我的设置，看看是否有人愿意提供帮助。

当我将 Apache 作为服务(以管理员身份)运行时，首先，文档根目录允许我通过 url 访问我的文件(不酷，但不是我的问题，因为我知道这是 Apache 中的文档根目录设置) session )。其次，当我输入 127.0.0.1/blog/blog/时，它会抛出 500 错误，并且 Apache 日志显示:

[Tue Sep 24 19:44:20 2013] [info] mod_wsgi (pid=2152): Create interpreter '127.0.0.1|/blog'.

顺便说一句，在 Windows 上。

首先:http.conf:

WSGIPythonPath C:/Users/jdp/Documents/www/mysite.com

<VirtualHost *:80>
    ServerName 127.0.0.1
    ServerAlias randomserver.com
    ServerAdmin randomguy@example.com

    DocumentRoot C:/Users/usr/Documents/www/

    <Directory C:/Users/usr/Documents/www/>
    Order allow,deny
    Allow from all
    </Directory>

    WSGIPassAuthorization On

    WSGIScriptAlias /blog C:/Users/usr/Documents/www/mysite.com/mysite/wsgi.py


    <Directory C:/Users/usr/Documents/www/mysite.com/mysite>
    <Files wsgi.py>
    Order deny, allow
    Allow from all
    </Files>
    </Directory>
</VirtualHost>

最初我试图这样做:

WSGIPythonPath C:/Users/usr/Documents/www/mysite.com:C:/Users/jdp/Documents/site/env/Lib/site-packages

但这导致路径 #1 出现问题，并且我无法导入 mysite.settings。我忽略了它，只是将缺少的包下载到我的 python 根目录中。

这是我在 C:/Users/usr/Documents/www/mysite.com/mysite/settings.py 中的设置

Aaaaaa这是我的 wsgi.py 文件:

os.environ["DJANGO_SETTINGS_MODULE"] = "mysite.settings"

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

和我的 urls.py:

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

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

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

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    url(r'^admin/', include(admin.site.urls)),
    url(r'^blog/', include('blog.urls', namespace='blogs')),
)

不确定其他信息是否有用。任何帮助将不胜感激!我花了太多时间尝试一些小调整并搜索 SO 和 mod_wsgi 文档但收效甚微。也许我是贪多嚼不烂，因为我是编程新手，但我认为我还没有陷入这样的困境。

您不应将项目源代码放在 DocumentRoot 下，该源代码记录在:

• http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide#Mounting_The_WSGI_Application

这将确保您的源代码不可访问。

500 错误是因为您的代码损坏，并且您可能没有正确设置 Django 以其他方式记录错误的详细信息。您似乎正在尝试使用日志系统通过电子邮件向您发送错误消息，但这些消息可能无法发送，因为您尚未设置 ADMINS。

启用 Debug模式允许错误显示在浏览器中。

FWIW，错误:

IOError: failed to write data

是因为在写回任何响应之前，浏览器的连接已被终止。您可能强制重新加载页面或执行其他操作。
