尝试在 Ubuntu Lucid Lynx 上启动 Apache2 mod_wsgi 来运行 Django，但没有成功

我有一个小最低安装 内存约为 256mb，是新安装的，没有运行任何特殊程序。我正在尝试部署虽然我使用 manage.py 成功运行了服务器，但我无法和在职的：

# service apache2 start && service apache2 status
* Starting web server apache2                      [ OK ] 
Apache is NOT running.

错误日志/var/log/apache2/error.log：

我的配置文件/etc/apache2/httpd.conf：

WSGIScriptAlias / /usr/local/django/deals/apache/django.wsgi

<Directory /usr/local/django/deals/apache>
Order deny,allow
Allow from all
</Directory>

文件/usr/local/django/deals/apache/django.wsgi：

import os
import sys

path = '/usr/local/django/deals'
if path not in sys.path:
    sys.path.append(path)

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

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

好像已经安装了：

我终于想出了如何解决这个问题。首先，我在升级时遇到麻烦到从因为服务器只提供 128mb（256mb 突发容量），升级过程中用完了。也许这个问题的解决方案就是直接升级。不过我确实升级了通过从源代码安装描述在这里，但这似乎并没有影响任何事情。

当我安装通过apt-get install apache2-mpm-prefork，所以它会使用它而不是作为调光器建议。我不确定问题是否在于导致我的其他错误未被记录，也许下一个遇到问题的人可以尝试跳过此步骤。当我切换到这错误日志却给出了以下错误。

 mod_wsgi (pid=1436): Exception occurred processing WSGI script '/usr/local/django/deals/apache/django.wsgi'.
 Traceback (most recent call last):
   File "/usr/local/lib/python2.6/dist-packages/Django-1.3-py2.6.egg/django/core/handlers/wsgi.py", line 250, in __call__
     self.load_middleware()
   File "/usr/local/lib/python2.6/dist-packages/Django-1.3-py2.6.egg/django/core/handlers/base.py", line 39, in load_middleware
     for middleware_path in settings.MIDDLEWARE_CLASSES:

     self._setup()
   File "/usr/local/lib/python2.6/dist-packages/Django-1.3-py2.6.egg/django/conf/__init__.py", line 42, in _setup
     self._wrapped = Settings(settings_module)
   File "/usr/local/lib/python2.6/dist-packages/Django-1.3-py2.6.egg/django/conf/__init__.py", line 89, in __init__
     raise ImportError("Could not import settings '%s' (Is it on sys.path?): %s" % (self.SETTINGS_MODULE, e))
 ImportError: Could not import settings 'deals.settings' (Is it on sys.path?): No module named deals.setting

这是因为我们无法导入设置模块。wsgi 与 Django 文档集成解释说我需要添加包含路径，一旦我更新，/usr/local/django/deals/apache/django.wsgi一切都会顺利运行。

import os, sys

sys.path.append('/usr/local/django/deals')
sys.path.append('/usr/local/django')

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

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

这是旧的 mod_wsgi 错误。请将 mod_wsgi 更新为较新版本。
