J'ai utilisé apt install mysql-server pour installer MySQL sur Ubuntu 16.04 mais pendant l'installation, il n'a pas demandé le mot de passe root.
Après l'installation, j'ai obtenu ERROR 1045 lorsque j'ai essayé de me connecter en tant que root y mysql_secure_installation a donné lieu à la même erreur. I purge d et autoremove d puis réinstallé mais cela ne fonctionne pas.
Comment puis-je résoudre ce problème ? Puis-je définir le mot de passe root si je ne l'ai pas défini lors de l'installation ?
