How to listen only to localhost on MongoDB

MongoDB Suggests that the easy way to handle security is to run it in a trusted environment, given that, "in such a configuration, one must be sure only trusted machines can access database TCP ports."

What would be the best approach for doing this? Is there a way for mongodb to natively only listen to localhost?

I'm using ubuntu 10.10

Solution 1:

Add the following line into mongodb.conf:

bind_ip = 127.0.0.1

As @Josh Rickard stated in comments: don't forget to restart the process after updating the config file:

service mongodb restart

Solution 2:

As Andreas mentioned in a round-about way:

mongod --bind_ip 127.0.0.1

Solution 3:

Note that although it didn't appear in the documentation last time I checked, you can also put this setting in the .conf file (vs. command line).

No setting = bind to all ips.
