> use admin
switched to db admin
> db.createUser({ user: 'admin', pwd: 'password', roles: [{ role: 'userAdminAnyDatabase', db: 'admin' }] })
Successfully added user: {
        "user" : "admin",
        "roles" : [
                {
                        "role" : "userAdminAnyDatabase",
                        "db" : "admin"
                }
        ]
}
> db.createUser({ user: 'rootAdmin', pwd: 'password', roles: [{ role: 'root', db: 'admin' }] })
Successfully added user: {
        "user" : "rootAdmin",
        "roles" : [
                {
                        "role" : "root",
                        "db" : "admin"
                }
        ]
}

2. Update /etc/mongod.conf

security:
  authorization: enabled

Do not use tab character to make indent, please use space char. Tab character will make service mongod fail to start.

3. Restart mongodb

ubuntu@ubuntu1404:~$ sudo service mongod restart
[sudo] password for ubuntu:
mongod stop/waiting
mongod start/running, process 1324

4. Try login with mongo shell

ubuntu@ubuntu1404:~$ mongo -u "admin" -p "password" admin
MongoDB shell version: 3.0.10
connecting to: admin

5. Example create database user

> use BillionaireX
switched to db BillionaireX
> db.createUser({ user: 'billionaire', pwd: 'password', roles: [{ role: 'dbOwner', db: 'BillionaireX' }] })
Successfully added user: {
	"user" : "billionaire",
	"roles" : [
		{
			"role" : "dbOwner",
			"db" : "BillionaireX"
		}
	]
}

6. Example Add 'show dbs' access to user

> use BillionaireX
switched to db BillionaireX
> db.grantRolesToUser("billionaire", [{ role: "readAnyDatabase", db: "admin" }]);
