When creating first admin user on mongdb cluster getting error “couldn't add user: not authorized on admin to execute command”

Question

I am using mongoDB Cluster with version 3.4 in google cloud compute engine, actually past week my database got attacked by hackers that\'s why i thought about using authorizatio

Answer 1

When a new database is setup with authorisation/security enabled but no users set up, you can only connect to it from the localhost. In your config file you should have bind ip set to 127.0.0.1 I think in order to make sure you connect to it with the correct authorisation to create new users.

This is what it says in Mongo course M103

By default, a mongod that enforces authentication but has no configured users only allows connections through the localhost.
