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

问题描述：

我遇到了将mongoengine加入我的django应用程序的问题。下面是我得到的错误：mongoengine.connection.ConnectionError：无法连接到数据库默认值：[Errno 111]连接被拒绝

mongoengine.connection.ConnectionError: Cannot connect to database default : 
[Errno 111] Connection refused

下面是我试图运行代码：

import getpass 

from mongoengine import connect 

from models import User 

connect('happy_lens') 

admin = User(username='dk', email='[email protected]') 
admin.password='pwd' 
admin.save()

及以下相关的settings.py代码：

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

    } 
} 

SESSION_ENGINE = 'mongoengine.django.sessions'

一切我搜索没有工作。请帮忙。

在/ var/lib中/ MongoDB的拆卸mongod.lock并重新启动服务或可能（如果你没有），你可以尝试从这里的解决方案http://stackoverflow.com/questions/24899849/connection-refused-to-mongodb-errno-111 –

我查找/ var/lib中的mongodb文件夹/并找不到它。你知道什么可能导致这个问题？我已经通过pip3安装 - 用户mongoengine安装了mongonenine。 – no8do

所以我想出了我自己的问题。我是mongo的新手，所以我认为它的工作方式与sqlalchemy的工作方式相同，即在pythonanywhere平台上自动创建sqlite数据库，但情况并非如此。

对于大家第一次使用pythonanywhere和mongo，确保你得到一个外部服务（我在Amazon AWS上使用MongoLab）。一旦你建立了一个数据库，你可以通过在mongoengine.connect函数中提供正确的MongoDB URI来连接它。

确保mongodb已启动并正在运行。

service mongod status 
service mongod start (on ubuntu)

我试着运行两条线，我得到了以下错误：mongod：无法识别的服务 – no8do

您使用的是哪个操作系统？你有没有正确安装mongodb？按照mongoDB安装说明（https://docs.mongodb.org/manual/administration/install-on-linux/）教程，确保它已正确安装在所需的操作系统上 –

Pymongo 3.0及以上版本都有这个problem.you应该先卸载最新版本，然后安装python-pymongo == 2.8.1
