PyMongo MongoClient SSH连接

Question

I'm trying to establish a connection with a MongoDB database via an SSH connection programmatically from python. I can create a MongoClient object to connect locally but I can't see how to establish an SSH connection for my MongoClient to use.

How would I do this?

Answer 1

First make sure you have no local MongoDB running on your machine, then ssh to the server where MongoDB is running:

ssh -L 27017:MYHOST:27017 MYUSER@MYHOST

Replace MYUSER and MYHOST with your username and host. Then, in another terminal window, run the "mongo" shell from your local computer. By default it connects to localhost:27017, which you've port-forwarded to the remote host. The "mongo" shell should connect correctly.

Then, create a PyMongo connection normally in Python:

>>> from pymongo import MongoClient
>>> c = MongoClient()
>>> c.test.command('buildinfo')
...

More info about SSH tunneling here:

This is not MongoDB-specific at all, any network protocol can be tunneled with SSH port-forwarding.
