Mac 上的 Django：Apache 与 mod_wsgi 配置问题

Question

我正在尝试使用 mod_wsgi 在 Apache 上运行本地 Django 服务器。我在 Mac 上运行开箱即用的 Apache。

hobbes3@hobbes3:~/Sites/mysite$ apachectl -v
Server version: Apache/2.2.21 (Unix)
Server built:   Nov 15 2011 15:12:57

Apache 正确加载 mod_wsgi。

hobbes3@hobbes3:~/Sites/mysite$ apachectl -t -D DUMP_MODULES | grep wsgi
Syntax OK
wsgi_module (shared)

在我的httpd.conf 文件中，我加载了apache_django_wsgi.conf，即

WSGIDaemonProcess django
WSGIProcessGroup django

Alias /mysite/ "/Users/hobbes3/Sites/mysite/"
<Directory "/Users/hobbes3/Sites/mysite">
Order allow,deny
Options Indexes
Allow from all
IndexOptions FancyIndexing
</Directory>

WSGIScriptAlias /mysite "/Users/hobbes3/Sites/mysite/apache/django.wsgi"

<Directory "/Users/hobbes3/Sites/mysite/apache">
Allow from all
</Directory>

我的django.wsgi 文件是

import os
import sys

paths = [ '/Users/hobbes3/Sites/mysite',
          '/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages',
]

for path in paths:
    if path not in sys.path:
        sys.path.append(path)

sys.executable = '/usr/local/bin/python'
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'

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

我也可以重新启动 Apache 而不会出现任何错误。但是当我尝试访问 http://localhost/mysite 时，我的浏览器提示我有 500 内部服务器错误。

我的 Apache 错误日志显示（我截断了日期和时间）：

mod_wsgi (pid=73970): Exception occurred processing WSGI script '/Users/hobbes3/Sites/mysite/apache/django.wsgi'.
Traceback (most recent call last):

    raise ImportError("Could not import settings '%s' (Is it on sys.path?): %s" % (self.SETTINGS_MODULE, e))
ImportError: Could not import settings 'mysite.settings' (Is it on sys.path?): No module named mysite.settings

我不知道为什么它不能导入mysite.settings，我不是在sys.path 中包含了那个吗？

settings.py 的完整路径是/Users/hobbes3/Sites/mysite/。

您已在路径中包含mysite，但您引用了mysite.settings。所以 Python 正在寻找一个 mysite 模块 within 它在路径上找到的目录。请改用settings。
