Django WSGI路径

Question

我在使用django设置wgsi时遇​​到问题。我正在关注这个http://docs.djangoproject.com/en/dev/howto/deployment/modwsgi/。然而，我仍然真的很困惑在哪里放置.wsgi文件，如果我需要设置sys.path。我已经在web root的外部和内部都尝试过了，我无法按预期工作。

# /home/ben/public_html/django_test/testproject/apache/django.wsgi:

import os
import sys

os.environ['DJANGO_SETTINGS_MODULE'] = 'testproject.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

Relivant apache conf：

DocumentRoot "/home/ben/public_html/django_test/testproject/"
WSGIScriptAlias / "/home/ben/public_html/django_test/testproject/apache/django.wsgi"

Apache Logs Error（标准apache 500页）：

ImportError: Could not import settings 'testproject.settings' (Is it on sys.path? ...

我可以通过使用它来让django至少抛出它自己的错误：

import os
import sys

path = '/home/ben/public_html/django_test/testproject'
if path not in sys.path:
    sys.path.append(path)

os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

导致了这个django错误页面：

ImportError at /admin/
No module named testproject.urls

我把wsgi放在与settings.py相同的级别，看起来像这样：

import os
import sys

sys.path.insert(0,os.sep.join(os.path.abspath(__file__).split(os.sep)[:-2]))


os.environ['DJANGO_SETTINGS_MODULE'] = 'yourprojectname.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

这是apache conf文件：

NameVirtualHost *:80
<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    ServerName www.yourprojectname.com
    Alias /media/ /home/diegueus9/workspace/yourprojectname/media/

    <Directory /home/diegueus9/workspace/yourprojectname/media/>
        Order deny,allow
        Allow from all
    </Directory>

    WSGIScriptReloading On
    WSGIDaemonProcess yourprojectname 
    WSGIProcessGroup yourprojectname
    WSGIApplicationGroup yourprojectname
    WSGIPassAuthorization On

    WSGIScriptAlias / /home/diegueus9/workspace/yourprojectname/yourfile.wsgi
    ErrorLog /var/log/apache2/yourprojectname-error.log

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel debug

    CustomLog /var/log/apache2/yourprojectname-access.log combined

</VirtualHost>

Here is a nice tutorial向您展示如何将mod_wsgi与Django以及与此问题无关的其他项目一起使用。

作为快速修复，您可以将其添加到sys.path：

path = '/home/ben/public_html/django_test/testproject'

还添加：

path2 = '/home/ben/public_html/django_test'

您还可以在Apache VirtualHost中更改Python路径：

WSGIDaemonProcess [...] python-path=/home/ben/public_html/django_test

但你也应该复习mod_wsgi文档并了解Graham Dumpleton在那里的建议。
