MongoDb Exiting with Code: 100 - mongodb

Question

I know that there are other questions similar to this, but they do not have the same exact log and I have tried many supposed solutions that haven't worked. This is my log:
2018-05-16T00:31:32.193-0400 I CONTROL [initandlisten] MongoDB starting : pid=16976 port=27017 dbpath=/data/db 64-bit host=Edan

2018-05-16T00:31:32.194-0400 I CONTROL [initandlisten] shutting down with code:100
I think that I closed my terminal window before shutting down the server, and now I can't get it to work. Any help would be greatly appreciated.

Answer 1

It is mentioned in the log that "Another mongod instance is already running" and you need to gracefully shut down it before starting the server again.
If it didn't work, forcefully kill the mongod process and remove the lock file.
If you are on unix environment,
Run ps -A | grep mongo
Copy the process id(s)
Run kill -9 [process id]
And then remove the mongo lock file
Run sudo rm /data/db/mongod.lock
