I installed MongoDB via Homebrew. Manually created the /data/db directory. Tried to run mongod command from Command Line, here's what happened :

What's going wrong ?

    what is the permissions on /data/db vs who is the user you are starting mongod process as? If that user doesn't have write permissions to the db directory this will happen. Commented Apr 24, 2014 at 4:05
  • do ls -ld /data/db and post the results. Then do whoami and post the result of that. It's not relevant whether the user you are running as has admin privileges or not. Commented Apr 24, 2014 at 4:15

The problem is that the files mongod is trying to write to are owned by root but you are running mongod as user sanjeetsuhag.

The correct fix would be to change ownership of the directory via command:

$ sudo chown -R sanjeetsuhag /data/db

This will make the directory and everything under it owned by the same user you are running mongod as, which will allow it to start.

I have same issues. I installed MongoDB with homebrew.

I think it needs admin priveledges.

I used : sudo mongod and it worked fine for me. Please try it.

service state will start and end like this if we use sudo mongod
