MongoDB - admin user not authorized

Easy Fix Guide: MongoDB - admin user not authorized 🐒

So you've been following the MongoDB documentation to add authorization to your MongoDB, but you're facing issues with the admin user not being authorized. Don't panic! We've got you covered with some easy solutions to get you back on track. 🚀

Understanding the Problem:

The error message you're seeing (not authorized on admin) indicates that the user you created (sa) does not have the necessary permissions to perform certain actions.

Solution:

To fix this issue, we need to grant the correct privileges to the admin user. Follow these steps:

1. Start by connecting to your MongoDB server using the mongo shell:

   /usr/bin/mongo localhost:27017/admin

2. Authenticate as the admin user you created (sa) using the following command:

   db.auth("sa", "pwd")

   Make sure to replace pwd with the actual password you set for the admin user. If the authentication is successful, you will see 1 as the output.

3. Grant the necessary privileges to the admin user using the grantRolesToUser command. Run the following command to grant the root role to the sa user:

   db.grantRolesToUser("sa", [{ role: "root", db: "admin" }])

4. Exit the mongo shell by typing exit.

5. Restart the MongoDB service to apply the changes:

   sudo service mongod restart

6. Reconnect to the mongo shell as the sa user and verify that the user has the required privileges:

   /usr/bin/mongo localhost:27017/admin -u sa -p pwd

7. You should now be able to perform administrative tasks and create other users with specific permissions. Try running the commands show collections to test if the authorization is working as expected.
