How did I enable access control for MongoDB?

MongoDB
1

Step 1

I executed in the MongoDB terminal:

use admin;
db.createUser ({
	user: "admin",
	pwd: "<password>",
	roles: [{role: "userAdminAnyDatabase", db: "admin"}, "readWriteAnyDatabase"]
});

Step 2

I have set in:

security:
  authorization: enabled

Step 3

service mongo restart
