MongoDB - shutting down with code 48

Question

I am trying to start MongoDB but the terminal returns the following error:

I am using Laravel Valet if that matters.

Answer 1

It seems like you have already a process running on the port where you want to start mongodb:

listen(): bind() failed Address already in use for socket: 0.0.0.0:27017
2017-02-06T16:26:27.038+0000 E NETWORK  [initandlisten]   addr already in use

you could try to kill the process that runs on that port with this command: sudo kill sudo lsof -t -i:27017

or define another port for mongodb if you have another program using that port.
to run mongodb on a port other than its default port (27017) use the --port 27018 argument when starting mongodb from the terminal

Answer 2

If you are using mac then you can simply kill the process running on port 27017 which is mongodb process in most cases.

Simply run the command.

npx kill-port 27017

After that you can run the mongod command as you normally do.

Or if you are using windows follow these steps

• Run command line as Admin
• netstat -ano | findstr :27017
• you will get pid in the end that is the process id to kill
• taskkill /PID <typeyourPIDhere> /F
• after successful termination of process you can run mongod as you usually do!

Enjoy!

Answer 3

Basically you just need to force quit the mongo, you can do this just by typing

sudo pkill -f mongod

and now you can start the server again with

mongod
