I\'ve installed mongodb and have been able to run it, work with it, do simple DB read / write type stuff. Now I\'m trying to set up my Mac to run mongod as a service.
mongod wasn't working to start the daemon for me but after I ran the following, it started working:
mongod
'mongod --fork --logpath /var/log/mongodb.log'
