local db not working using mongo localhost

Question

I'm trying to get a localhost MongoDB DB working, but I don't get it. I use Mac.

Here is what I write in the shell (zsh) :

mongo

I get this error :

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 :
connect@src/mongo/shell/mongo.js:362:17
@(connect):2:6
exception: connect failed
exiting with code 1

Also, when I write this :

mongod

I get this :

it also doesn't work with node when I try to connect to local DB. Ultimately, I want to connect to a local db via node using 'Dotenv' and this line of code : DATABASE=mongodb://localhost:27017/node-form

but I get error again :

Plus, it's not running anywhere :

gaetan@MacBook-Pro-de-Gaetan ~ % sudo killall mongod
Password:
No matching processes were found
gaetan@MacBook-Pro-de-Gaetan ~ % sudo killall mongo 
No matching processes were found
gaetan@MacBook-Pro-de-Gaetan ~ % sudo killall mongodb
No matching processes were found
gaetan@MacBook-Pro-de-Gaetan ~ %

The problem comes from : "Failed to unlink socket file". And since `mongod` doesn't work. The mongo service can't start, and you cant connect to it with node.js. Maybe this could help : https://stackoverflow.com/questions/29813648/failed-to-unlink-socket-file-error-in-mongodb-3-0 — AlexisG, Sep 07 '20 at 10:18
I didn't worked either. Plus I didn't understood half the things they said, I'm new at this. — Gaëtan CHABOUSSIE, Sep 07 '20 at 12:25

Try creating a new 'db' and 'log' directory in the data directory under the 'MongoDB' installation directory and a new 'mongo.log' file under the 'log' directory

Thanks for your answer. But i think something went wrong with the installation. A couple weeks ago, i formated my mac and reinstalled everything in a clean way using brew. Now, everything works fine. Thanks anyway

You could give the solution here a shot. SocketException: Address already in use MONGODB

Since it's returning a socket error the mongodb default port could be in use by another service even when it's highly unlikely.
