Vous avez encore perdu votre liste de mots de passe ? Les donn\u00e9es de connexion des principaux utilisateurs sont rapidement perdues et ne sont pas enregistr\u00e9es dans le syst\u00e8me lui-m\u00eame.
\nIl est certainement plus facile ici avec les bases de donn\u00e9es utilis\u00e9es par Contenu<\/a> Le mot de passe est ici stock\u00e9 en texte clair dans les fichiers de configuration respectifs. Ce n'est pas le cas pour l'utilisateur principal du serveur de base de donn\u00e9es.
\nEn g\u00e9n\u00e9ral, le nom d'utilisateur est root. \u00c0 l'adresse suivante : Plesk<\/a> installations, le nom d'utilisateur \"admin\" est utilis\u00e9. Le mot de passe d'un serveur Plesk peut \u00eatre facilement r\u00e9cup\u00e9r\u00e9 dans le fichier .psa\/shadow. Par exemple : avec la commande :<\/p>\n

mysql<\/a> -uadmin -p`cat \/etc\/psa\/.psa.shadow<\/code><\/p>\n

Si vous devez r\u00e9initialiser compl\u00e8tement le mot de passe, il suffit de suivre les \u00e9tapes suivantes.<\/p>\n

Quitter le serveur de la base de donn\u00e9es. Par exemple, sous Centos7 avec MariaDB avec <\/p>\n

systemctl stop mariadb.service<\/code><\/p>\n

Si vous utilisez un autre serveur de base de donn\u00e9es, cela peut \u00e9galement \u00eatre fait avec<\/p>\n

\/etc\/init.d\/mysql stop<\/code><\/p>\n

MariaDB \/ MySQL root Changer le mot de passe<\/h2>\n

Nous d\u00e9marrons maintenant le serveur de la base de donn\u00e9es sans restrictions et sans gestion des droits, de sorte qu'il puisse \u00eatre administr\u00e9 sans mot de passe. Pour ce faire, nous utilisons l'option -skip-grand-tables, qui supprime les restrictions, et -skip-networking, qui emp\u00eache l'acc\u00e8s externe pendant la configuration.<\/p>\n

mysqld_safe --skip-grant-tables --skip-networking &<\/code><\/p>\n

Vous pouvez maintenant changer facilement le mot de passe MySQL.<\/p>\n

mysql -u root
\nmysql> use mysql ;
\nmysql> update user set password=PASSWORD(\"le_mot_de_passe_souhait\u00e9\") where User='root
\nmysql> flush privileges ;
\nmysql> exit<\/code><\/p>\n

Maintenant, le mot de passe est modifi\u00e9 et le serveur de la base de donn\u00e9es peut \u00eatre ferm\u00e9.<\/p>\n

fermeture de mysqladmin<\/code><\/p>\n

Pour qu'il puisse ensuite \u00eatre lanc\u00e9 normalement.<\/p>\n

systemctl start mariadb.service<\/code><\/p>\n
