Question

I want to connect to my mongoDB using pymongo. But I have this error :

raise ConnectionFailure(str(e))
pymongo.errors.ConnectionFailure: [Errno -2] Name or service not known

I have obviously checked url,password...etc of the database connection. My mongoDb instance is running.

sudo service mongodb status
mongodb start/running, process 10199

Thanks!

使用MongoClient构造函数。

假设环回的默认端口，数据库为my_db而您的集合为my_coll，请尝试：

from pymongo import MongoClient
my_connection = MongoClient('mongodb://localhost:27017')
db = my_connection['my_db']
coll = db['my_coll']
#Sample cursor
my_cur = coll.find()

PyMongo - ConnectionFailure
