virtualenv 上的 django+mod_wsgi 不起作用

Question

我刚刚在 virtualenv 上完成了 django 应用程序的设置，使用 Fabric 脚本部署顺利，但现在 .wsgi 不起作用，我尝试了互联网上的所有变体，但没有运气。我的 .wsgi 文件是：

import os
import sys
import django.core.handlers.wsgi

# put the Django project on sys.path
root_path = os.path.abspath(os.path.dirname(__file__) + '../')
sys.path.insert(0, os.path.join(root_path, 'kcdf'))
sys.path.insert(0, root_path)

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

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

我不断收到相同的错误：

我的虚拟环境位于 /home/user/webapps/kcdfweb 我的应用程序是 /home/user/webapps/kcdf.web/releases/current/project_name 我的 wsgi 文件 home/user/webapps/kcdf.web/releases/current/project_name/apache/project_name.wsgi

Answer 1

我建议您查看文档，了解如何将 Virtualenv 与 mod_wsgi 结合使用。他们提供了一些连接虚拟环境的替代方法，这可能更适合您。

Answer 2

您需要添加距 wsgi 文件向上两个目录，因此

root_path = os.path.abspath(os.path.dirname(__file__) + '../')

您应该添加

root_path = os.path.abspath(os.path.join(os.path.dirname(__file__), '../', '../'))

...，因为您的 wsgi 文件位于项目文件夹下名为 apache 的目录中。

Answer 3

如果您使用的是 virtualenv，则需要在 WSGI 脚本中激活它以正确设置路径。

root_path = os.path.abspath(os.path.dirname(__file__) + '../')
activate_this = os.path.join(root_path, "bin/activate_this.py")
execfile(activate_this, dict(__file__=activate_this))

Answer 4

您的“kcdf”目录中有 __init__.py 文件吗？如果没有它，您的设置文件将无法导入。

另外，如果您希望能够从 virtualenv 导入内容，您应该在 virtualenv 的 site-packages 目录上调用 site.addsitedir() 。有关详细信息，请参阅mod_wsgi 文档。虽然如果它甚至无法导入您的设置，我认为这不是您当前的问题。
