在通过 Apache 运行的 Django 中记录消息

Question

我在我的笔记本上运行 Ubuntu 14.04，我正在使用 Django 1.6.4（带有 virtualenv）和 Apache 2.4.7。

我建立了一个站点并希望从我的视图中将一些调试信息记录到我的名为homepage.log 的日志文件中（我的应用程序的名称是主页）。当我使用 Django 的内置服务器运行我的站点时，所有消息都显示在日志文件中，但是当使用 Apache 运行时，文件中没有消息。我的项目位于/home/nick/Workspace/Web/kleyboldt_django/ 下（kleyboldt 是我为之写作的人的名字）。那里有我的 wsgi 文件、名为 env 的虚拟环境和名为 kleyboldt-homepage 的实际项目。我想登录kleyboldt_homepage/homepage.log。我的设置是：

/etc/apache2/sites-available/mks.conf

WSGIDaemonProcess mks.com python-path=/home/nick/Workspace/Web/kleyboldt_django/kleyboldt_homepage:/home/nick/Workspace/Web/kleyboldt_django/env/lib/python2.7/site-packages

/home/nick/Workspace/Web/kleyboldt_django/kleyboldt_homepage/kleyboldt_homepage/settings.py

...

        },
        'simple': {

        'null': {
            'level': 'DEBUG',
            'class': 'django.utils.log.NullHandler',
        },
        'console': {
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',


  'formatter': 'simple',
    },
    'file': {
        'level': 'DEBUG',
        'class': 'logging.FileHandler',
        'filename': 'homepage.log',
        'formatter': 'verbose',
    }
},
'loggers': {
    'kleyboldt_homepage': {
        'handlers': ['console', 'file'],
        'level': 'DEBUG',
    },
},

}

/home/nick/Workspace/Web/kleyboldt_django/kleyboldt_homepage/homepage/views.py

import logging

logger = logging.getLogger('kleyboldt_homepage')

def home(request):
    logger.warning("test")
    return render(request, 'homepage/home.html', {})

运行 Apache 时，警告永远不会出现。

更新 1

我将日志文件更改为/tmp/homepage.log，但随后 Apache 显示一条错误消息，告诉我发现了错误配置。因为我将 VirtualHost 中的错误日志设置为主页的日志文件，Apache 将错误消息转储在其中。

显然 Apache 没有写入该文件的权限。因此，我将/tmp/homepage.log 的组更改为www。现在将调试消息写入此文件即可。现在我将项目中的homepage.log 组也更改为www。不幸的是，它不起作用。错误日志显示 Apache 没有权限写入我的项目文件夹。我应该改变什么？

Answer 1

现在尝试将日志文件名设置为完整路径。 'filename': 'homepage.log', 试试 'filename': '/tmp/homepage.log',

如果可行，您可以使用 os.path 将其设置为相对于您的应用文件夹。

Answer 2

经过一些尝试，我通过将 homepage.log 的用户更改为 www-data 并重新加载 Apache2 来解决问题。当您重新加载服务器然后立即打开站点时，您可能会看到一条错误消息。
