Can't connect MongoDB via Shared Private Networking

Posted on April 14, 2014

Hi,

I’ve setup a droplet with Shared Private Networking enabled. I’ve provisioned it with Ubuntu 12.10 x64. Also, I’ve installed mongodb using ‘sudo apt-get install mongodb’ command.

I tried using mongoose to connect to the mongodb droplet using the default port. It said failed to connect.

I used the command below:

var mongoose = require(‘mongoose’); mongoose.connect(‘mongodb://XXX.XXX.XXX.XXX:27017/database’);

Things I’ve tried…

  1. Ping the MongoDB droplet from the app droplet. It works.
  2. Ran ‘mongo’ command on the MongoDB droplet. It works.
  3. Ran ‘sudo netstat -plunt’ and saw the mongod process listening on the 27017 port.

Any idea what I could try to verify it or what I can do to resolve this?

Cheers, Mickey

Yes. Here’s the list. <br> <br>-P INPUT ACCEPT <br>-P FORWARD ACCEPT <br>-P OUTPUT ACCEPT <br> <br>Does it means that it accept all ports?

It solved. The bind_ip is set to 127.0.0.1 by default. Need to change it to 0.0.0.0. Cheers.

I also recommend adding an IPTables rule that drops all packets to the MongoDB ports on the eth0 interface: <br><pre>sudo iptables -A INPUT -p tcp -m tcp -i eth0 --dport 27017 -j DROP</pre>
