Si on veut un utilisateur autre que root avec un mot de passe pour administrer phpMyAdmin
On créé ensuite un utilisateur avec tous les droits pour ne pas utiliser root :

mysql -u root
CREATE USER 'coco'@localhost IDENTIFIED BY 'mdp';
GRANT ALL PRIVILEGES ON *.* TO 'coco'@localhost IDENTIFIED BY 'mdp';
GRANT ALL PRIVILEGES ON *.* TO 'coco'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;
exit;
