Je ne peux pas convertir myISAM à innodb

Question

J'ai fait un nettoyage et restaurer.

1. J'ai sauvegardé mes tables innodb actuelles. (mysqldump)
2. Je l'ai chargé dans la base de données.
3. Pour une raison quelconque ... les tables sont maintenant toutes myisam au lieu d'innodb ... bizarre!

4. J'essaie de faire:

   TABLEAU xxx ALTER MOTEUR = InnoDB;

Et il ne fait rien à n'importe quelle table.

"Afficher le statut de table" est toujours "MyISAM"

mysql> alter table auth_user_user_permissions engine=innodb;

# * InnoDB

# InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.

Answer 1

Je vois dans votre show engines sortie qui InnoDB est désactivé dans votre MySQL installer. Vous devez l'activer pour pouvoir convertir vos tables de MyISAM en InnoDB.
