Uninstall MongoDB on Mac OS X

Question

When I try to run mongod from the terminal, I get the following error:

2014-07-02T23:56:24.797-0700 [initandlisten] ERROR: listen(): bind() failed errno:48 Address already in use for socket: 0.0.0.0:27017 2014-07-02T23:56:24.797-0700 [initandlisten] ERROR: addr already in use

I recently realize that I have two versions of MongoDB on my Mac, and think this may be the source for the above error. (Plus, I do not need two version.) I tried Googling, but was not able to find clear directions on how I can uninstall. I have development version 2.7.0 AND 2.6.3.

Thanks so much in advance for the help!

if you installed them using brew you can brew uninstall mongo. To fix your socket issue, kill all mongodb process using ps aux | grep mongo to see the processes and kill -9 process_number to kill it. — Pierre-Louis Gottfrois
Thanks so much for the quick reply, Pierre-Louis. Unfortunately, still the same issue. Tried brew uninstall as well as the kill -9 with the number. Still get ERROR: listen(): bind() failed errno:48 Address already in use for socket: 0.0.0.0:27017. — jasenlew
After a little more pain, Pierre-Loiuse, pkill -mongod worked. MongoDB essentially always seems to be running even after terminal close and re-load. I need to either pkill -mongod on terminal load, OR control-C the running database before exiting terminal. Thanks again!! — jasenlew
FYI, if you have a running mongod there are more polite ways to shutdown than kill -9 (which should only be used in extreme desperation). See: How to stop mongo DB in one command. — Stennie
@Pierre-LouisGottfrois your comment should have been an answer. — user9903

Run the following commands to remove mongodb from the launch/startup and to uninstall it using Homebrew:

# See if mongo is in the launch/startup list
launchctl list | grep mongo

# Remove mongodb from the launch/startup
launchctl remove homebrew.mxcl.mongodb

# Kill the mongod process just in case it's running
pkill -f mongod

# Now you can safely remove mongodb using Homebrew
brew uninstall mongodb

Just double-check in /usr/local/bin/ to make sure that the mongodb commands are removed.
