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。 我太沮丧了，无法继续研究它，所以我将发布设置，看看是否有人愿意提供帮助。

首先，当我运行Apache作为服务（以管理员身份）时，文档根目录允许我通过url访问文件（虽然不酷，但实际上不是我的问题，因为我知道这是Apache conf中的文档根目录设置）。 其次，当我键入127.0.0.1/blog/blog/时，它将引发500错误，并且Apache日志显示为：

[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>

最初我试图做的是：

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，我无法导入mysite.settings。 我忽略了它，只是将缺少的软件包下载到了我的python根目录。

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

这是我的wsgi.py文件：

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')),
)

不知道其他信息是否有用。 任何帮助将不胜感激！ 我花了太多时间尝试进行一些细微的调整，并搜索SO和mod_wsgi文档而徒劳无功。 由于我是编程新手，所以我可能会付出太多努力，但我不认为自己已经被这样的困扰了。

Answer 1

您不应将项目源代码放在DocumentRoot下，该文档记录在：

• 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错误是由于您的代码损坏而引起的，也可能是因为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记录系统将其通过电子邮件发送给您错误消息，但是由于您尚未设置ADMINS，因此这些消息可能无法通过。

启用调试模式可以使错误显示在浏览器中。

FWIW，错误：

IOError: failed to write data

这是因为在可以写回任何响应之前，已终止了来自浏览器的连接。 您可能已强制重新加载页面或其他内容。

@Foon @Graham Dumpleton

谢谢！ 一旦我更改了数据库设置以使其与PGAdmin中的postgres设置相匹配并修复了时区错误，便会加载页面。

DEBUG = False
TEMPLATE_DEBUG = DEBUG

ADMINS = (
     ('usr', 'usr@gmail.com'),
)

MANAGERS = ADMINS

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2', 
        'NAME': 'django_db',    
        'USER': 'usr',
        'PASSWORD': 'blahblahblah',
        'HOST': 'localhost',                    
        'PORT': '5432',                     
    }
}

ALLOWED_HOSTS = ['*']

TIME_ZONE = 'America/New_York'

现在，我只需要弄清楚如何在服务器上配置我的静态文件。
