Root user is disabled by default, so make a new mysql user and give all privileges to that user. An example:


sudo mysql -p -u root

mysql> CREATE USER 'username_here'@'%' IDENTIFIED BY 'password_here';

mysql> GRANT ALL PRIVILEGES ON *.* TO 'username_here'@'%' WITH GRANT OPTION;

Replace username_here with real username and password_here with real mysql password.
