mongoengine.connection.ConnectionError：无法连接到数据库默认值：[Errno 111]连接被拒绝

Question

我在将mongoengine整合到我的django应用程序时遇到问题。以下是我得到的错误：

Traceback (most recent call last):
  File "/home/dk2459/.local/lib/python3.4/site-packages/pymongo/mongo_client.py", line 374, in __init__
    self._ensure_connected(True)

    member, nodes = self.__find_node()

    raise AutoReconnect(', '.join(errors))
pymongo.errors.AutoReconnect: [Errno 111] Connection refused
During handling of the above exception, another exception occurred:

    raise ConnectionFailure(str(e))

    return get_connection(alias)

    raise ConnectionError("Cannot connect to database %s :\n%s" % (alias, e))
mongoengine.connection.ConnectionError: Cannot connect to database default :
[Errno 111] Connection refused

下面是我尝试运行的代码：

下面是相关的设置.py代码：

DATABASES = {
    'default' : {
        'ENGINE': 'django_mongodb_engine',
        'NAME': 'happy_lens',
        'HOST': '192.168.1.35',
        'POST': 12345

   }
}

SESSION_ENGINE = 'mongoengine.django.sessions'

我找的东西都没用。请帮忙。在
