MongoDB error message: Failed to unlink socket file /tmp/mongodb-27017.sock errno:13 Permission denied

Hello there. I installed mongodb and ran it, but keep getting the following message (I've pasted the entire message here including the error):

You could try and run the mongod binary with sudo or su.

If it doesn't help, try deleting the referred file.

And when the 2 steps before don't work -> check the folder permissions with: " ls -l " to see whos the owner of the folder and what permissions are bound to the folder.

And a piece of advice: the standard location for the db data is always so problematic to access - the data is save under "/data/db" by default -> meaning that it's saved on the root folder of your system which can prove a bit problematic -> just like your problem now.... My advice is that you save the data from your database to a folder in the mongo folder:

create a folder = mkdir mongo/data/db

than when you start the mongod binary add " --dbpath mongo/data/db " flag to start command to tell mongo where the data should be stored.

If you still need help, you can add me on skype: nejc.vukovic
