访问Django项目时发生内部服务器错误

Question

我正试图在centos 6.3服务器中设置一个Python2.7+Django+virtualenv+mod_chGi环境，通过apache运行我的python应用程序。 但是我在尝试通过apache访问应用程序时遇到了内部错误。错误日志显示以下内容。在

prev_sys_path = list(sys.path)

site.addsitedir(vepath)

sys.path.append('/var/www/html/djangosites')

new_sys_path = [p for p in sys.path if p not in prev_sys_path]

for item in new_sys_path:

    sys.path.remove(item)

sys.path[:0] = new_sys_path

from django.core.handlers.wsgi import WSGIHandler

有谁能指出我的设置有问题吗？在

问候

Answer 1

将此行添加到spark.wsgi文件：

sys.path.append('/var/www/html/djangosites/spark')

因为您的django站点位于该目录中

Answer 2

您是否可以尝试用更简单的方法来更改您的wsgi，例如：

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "spark.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

也许这有助于更容易地发现问题

还可以使用默认的wsgi文件（spark/wsgi.py）而不是spark.wsgi，当然可以通过更改apache配置文件中的WSGIScriptAlias指令来实现。下面是一个带有站点设置的简单apache配置文件的示例，测试一下，让我知道：
