I am running a mongo database on Digital Ocean. I’ve set it up with the following tutorial: Mongodb setup and secured it with this tutorial: MongoDb security
Now I am trying to create a dump of a particular database. I am using the following command as stated in this article: Backup & Restore Mongodb:
sudo mongodump --db dbName --out /var/backups/mongobackups/date +”%m-%d-%y”“
However, I am getting the following error message:
Failed: error getting collections for database 'dbName': error running 'listCollections'. Database: 'dbName' Err: command listCollections requires authentication.
I’ve logged in on my server with root user. What am I missing?

As the error clearly says “command listCollections requires authentication.” you should try “Dump database with username & password mongodump -u=USERNAME -p=PASSWORD –db=DB_NAME.”
