PyMongo - 连接失败

Question

我想使用 pymongo 连接到我的 mongoDB。 但我有这个错误：

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

我显然已经检查了数据库连接的 url、密码...等。 我的 mongoDb 实例正在运行。

sudo service mongodb status
mongodb start/running, process 10199

谢谢！

使用MongoClient构造函数。

假设环回上的默认端口，您的数据库是my_db并且您的集合是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()
