Il y a des questions similaires, mais aucune n'a résolu mon problème, alors je m'excuse si j'ai manqué quelque chose.
J'utilisais mysqldbcopy pour faire une copie d'une base de données lorsque mon instance n'avait plus d'espace libre. Mysql a planté et n'a pas pu redémarrer. Pour libérer de l'espace, j'ai supprimé le dossier contenant le nom de la nouvelle base de données de l'application /var/lib/mysql . Mysql ne redémarrait toujours pas, alors j'ai supprimé /var/lib/mysql et j'ai essayé une réinstallation avec sudo mysql_install_db . Cela a fonctionné, mais je ne pouvais plus me connecter avec ou sans mon mot de passe, et je ne pouvais pas réinitialiser mon mot de passe.
Comme dernier essai, j'ai juste fait
sudo apt-get remove --purge mysql*mais lorsque j'effectue l'installation de la résine, j'obtiens les résultats suivants
