Make sure you have the 'root' mysql password available to authenticate:
Enter the mysql CLI with following command and enter the mysql root password:
$ mysql -u root -p
Enter password:
We can now create a user 'testUser' with password 'Temporary123' and grant him access to the 'testDB' database:
mysql> grant all privileges on testDB.* to 'testUser@localhost' identified by 'Temporary123';
Query OK, 0 rows affected (0.00 sec)
Make sure to flush the privileges of the changed configuration:
mysql> flush privileges;
That's it!
