HELP: Brew mongodb-community@5.0 error [MacOS]

Hello
I am having hard time setting up mongo db server.

Process:

When I start the database by brew services start mongodb-community@5.0, it does not give me any error message. However, when I look at the status, it is showing an error status, without any reason. Because of this, I cannot connect to the database (using mongo command).

I am using M1 mac but with Rosetta terminal and homebrew for intel macs (you can see that install location is /usr/local, not /opt/homebrew).

I also tried downgrading to v4.4 or use M1 version of Mongodb but I get the same error.

I spent a few hours googling for answers but none worked.
I really need help.

Thanks.

Welcome to the MongoDB Community Forums @REGO350 !

I think that should be OK as long as brew --prefix reports /usr/local and the right substitutions were made in /usr/local/etc/mongod.conf.

Can you check the MongoDB logs for errors. Something like this should show you the last lines in the log:

tail $(brew --prefix)/var/log/mongodb/mongo.log

I have MongoDB 5.0 installed on an M1 via brew, but when I installed Homebrew it used the preferred default prefix of /opt/homebrew.

Thank you for the quick reply.
This is what I for opt/homebrew:

Could be permission issues
Check ownership of /tmp/mongodb-27017.sock
Try to remove this file and start the service again
