所以我有这个Django / Angular项目，我被抛弃了，我在新服务器上安装它时遇到了麻烦。我安装了apache / python / pip / django和所有需要的reqs，此时我试图让Django与MongoDB服务器通信。
编辑：该项目使用Django作为AppServer，Apache / mod_wsgi作为Web服务器使用AngularJS作为客户端/前端部分。
UNIX环境 CentOS 7，SELinux = yes
仅仅是为了测试，我没有在MongoDB端为数据库/集合设置任何身份验证。
这是我的settings.py文件的一部分：
# Django settings for my_proj project.
from mongoengine import connect
connect('CoreRubrics',host='<url>',port=27017)
我也是这样试过的：
#DATABASES = {
# 'default': {
# 'ENGINE': 'django_mongodb_engine',
# 'NAME': 'CoreRubrics',
# 'HOST': '<url>'
# }
#}
这是我得到的错误。

由于它说权限被拒绝且没有身份验证，我只能假设某处存在文件权限错误？
