Connecting to a Database

If you are connecting to an instance using Python, an SSL certificate is optional, but downloading an SSL certificate and encrypting the connection will improve the security of your instance.

SSL is disabled by default for a new DDS instance. To enable SSL, see Enabling SSL.

Prerequisites

To connect an ECS to an instance, the ECS must be able to communicate with the DDS instance. You can run the following command to connect to the IP address and port of the instance server to test the network connectivity.
curl ip:port

If the message It looks like you are trying to access MongoDB over HTTP on the native driver port is displayed, the ECS and DDS instance can communicate with each other.
Install Python and third-party installation package pymongo on the ECS. Pymongo 2.8 is recommended.
If SSL is enabled, download the root certificate and upload it to the ECS.

Connection Code

Enabling SSL

dbs = connection.database_names()
connection = MongoClient(conn_urls,connectTimeoutMS=5000,ssl=True, ssl_cert_reqs=ssl.CERT_REQUIRED,ssl_match_hostname=False,ssl_ca_certs=${path to certificate authority file})
conn_urls="mongodb://rwuser:rwuserpassword@ip:port/{mydb}?authSource=admin"
from pymongo import MongoClient
import ssl
est_database
print "connect database success! database names is %s" % dbs

Disabling SSL

import ssl
from pymongo import MongoClient
conn_urls="mongodb://rwuser:rwuserpassword@ip:port/{mydb}?authSource=admin"
connection = MongoClient(conn_urls,connectTimeoutMS=5000)
dbs = connection.database_names()
print "connect database success! database names is %s" % dbs
