Question

我测试了一个连接到MongoDB的python程序，数据库驱动程序名为pymongo，但收到了以下错误。

相关的环境：

MongoDB：version = 2.6.1
Python：version = 2.7.9
pymongo：version = 2.8

而且，错误是：

>>> import pymongo
>>> conn = pymongo.Connection('localhost', 27017)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/site-packages/pymongo/connection.py", line 241, in __init__
    max_pool_size, document_class, tz_aware, _connect, **kwargs)
  File "/usr/local/lib/python2.7/site-packages/pymongo/mongo_client.py", line 377, in __init__
    raise ConnectionFailure(str(e))
pymongo.errors.ConnectionFailure: [Errno 61] Connection refused

它有什么问题？

Answer 1

首先，您必须使用cmd以root用户身份连接到终端： “sudo mongod”并确保您的文件夹/ data / db对编辑没有任何限制。

Answer 2

关于你的问题，由于Mongo Daemon无法启动而且没有收听，你会收到连接错误。您可以尝试以下步骤：

MongoDB将/ data / db作为默认数据目录。

您应该通过 mongod 命令启动MongoDB。

重试通过pymongo驱动程序连接到MongoDB。（在python shell中）
```
>>> conn = pymongo.Connection('localhost', 27017)
>>>
```

MongoDB在shell窗口上打印日志信息，如下所示：

希望能帮到你:)。
