Issues setting up MongoDB community 5.0 on MacOS "Error setting up listener"

[Lucy_Mac]

Hi,

I’m really new to MongoDB and I’m trying to connect to MongoDB locally in order to be able to develop a project but am coming into issues that I don’t really understand, so hoping for some help.

I am installing for Mac OS and followed the instructions on https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/

I ran brew services start mongodb-community@5.0 and then ran brew services list and I have the following error:

“mongodb-community error 12288 root ~/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist”

Looking in the log file I can see the error:

{"t":{"$date":"2022-03-03T07:50:40.907-05:00"},"s":"E", "c":"CONTROL", "id":20568, "ctx":"initandlisten","msg":"Error setting up listener","attr":{"error":{"code":9001,"codeName":"SocketException","errmsg":"Address already in use"}}}

Let me know if you need anymore information. This is my first time setting up something like this so I am a bit out of my depth.

Thanks

To clarify, I’ve also run lsof -iTCP -sTCP:LISTEN and I don’t think there are any ports using Mongo

After talking through with a colleague, I managed to solve the problem. Sharing here in case someone has a similar issue.

Although I couldn’t see mongod in the above command I ran sudo lsof -iTCP -sTCP:LISTEN -n -P and then killed the mongod port kill 22311

After that I got a different error:

{"t":{"$date":"2022-03-03T08:19:38.033-05:00"},"s":"E", "c":"CONTROL", "id":20557, "ctx":"initandlisten","msg":"DBException in initAndListen, terminating","attr":{"error":"NonExistentPath: Data directory /data/db not found. Create the missing directory

So I created a folder with a path ~/data/db and then restarted mongod
sudo mongod --dbpath=Documents/Code/mongodb/data/db

The connection is now working.
