Issues starting MongoDB on MacOS

I’ve installed MongoDB through my terminal using Homebrew. I did all the correct steps listed on their website. I get many errors when running mongod and mongo .

When I run mongod

When I run mongo :

MongoDB shell version v4.4.0
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: Connection refused :

Hi @Isaac_Medina,

It looks like a permissions problem:

 file","attr":{"path":"/tmp/mongodb-27017.sock","error":"Permission Denied

Is a mongod already running or the user running the process can’t unlink this file.

Have you tried running with sudo…

Best
