MySQL comment réparer l'utilisateur après que j'ai ajouté par erreur localhost à l'utilisateur au lieu de 127.0.0.1

0

Je voulais supprimer les utilisateurs inutiles, modifier les mots de passe et les hôtes de MySQL, car quelqu'un commençait à insérer des données dans ma base de données.

J'ai supprimé tous les utilisateurs sauf celui que ma base de données utilise, appelé forge. Pour cet utilisateur, j'ai remplacé% in hôte / serveur par 127.0.0.1 et tout fonctionne correctement sur la base de données de test.

Sur ma base de données de production, j'ai supprimé tous les utilisateurs de Forge et j'ai commis une erreur en entrant localhost au lieu de 127.0.0.1.

Maintenant, le site ne peut pas accéder à la base de données. J'ai également accès à la console et je ne peux pas me connecter à mysql:

ERREUR 1045 (28000): Accès refusé pour l'utilisateur 'forge' @ 'localhost' (avec mot de passe :)

J'ai cherché partout la solution et essayé beaucoup de choses, mais le problème demeure. J'ai essayé de passer les tables de subventions et d'utiliser également mysqld --init-file où j'ai essayé de modifier les paramètres des utilisateurs, mais rien n'y fait.

Toutes les idées sont les bienvenues. Je ne veux pas utiliser la sauvegarde car elle est ancienne et je perdrais beaucoup de données.

Deux solutions:

  1. MySQLd essayait de créer le socket et le fichier de verrouillage mais le répertoire parent était manquant. 

    sudo mkdir /var/run/mysqld
sudo chown mysql:mysql /var/run/mysqld
  2. Ajouter skip-external-locking à my.cnf sous le [mysqld] section, puis redémarrez le service.

J'ai déjà ce répertoire et ce socket et verrouille les fichiers. Il appartient à l'utilisateur / groupe approprié drwxr-xr-x 2 mysql mysql 100 déc. 25 14:45 mysqld. Il y a déjà skip-external-lock dans my.cnf. Rien d'autre?

Essayer mysql_upgrade -u adminname -p et redémarrer le service

J'ai trouvé une solution.

J'ai copié les fichiers utilisateur mysql dans / var / lib / mysql / mysql De plus, je devais les envoyer à mysql, redémarrer mysql, et je peux me connecter avec les utilisateurs à partir des fichiers de sauvegarde.

Toutes les bases de données sont préservées.
