Vous ne pouvez pas démarrer le serveur MySQL en raison d'autorisations de fichier incorrectes?
J'essaie de démarrer le serveur, puis de réparer l'utilisateur root en
$ mysql -u root mysql
$mysql> UPDATE user SET Password=PASSWORD('my_password') where USER='root';
$mysql> FLUSH PRIVILEGES;
Mais le serveur ne peut pas être démarré:
$ mysqld --skip-grant-tables

Le dossier entier devrait appartenir à mysql
cd /usr/local/mysql-5.6.21-osx10.8-x86_64/data/
chown -R mysql:mysql *
Ensuite, redémarrez mysql
Essaie !!!
Je trouve une autre raison de la même erreur. J'utilise homebrew pour installer mysql.
Le serveur n'a pas pu être arrêté en utilisant simplement la commande:
mysql.server stop
Le processus mysql redémarrera automatiquement. La seule façon d'arrêter cela est d'utiliser cette commande:
brew services stop mysql
Ensuite, vous pouvez résoudre le problème avec l'utilisateur root.
N'oubliez pas que des choses comme apparmor peuvent également bloquer l'accès en écriture aux répertoires de mysql.
Voir des endroits comme /etc/apparmor.d/usr.sbin.mysqld, et donnez "** rwk" à votre datadir mysql. (Nécessite le redémarrage de l'apparmeur) Voir un endroit comme /var/log/kern.log pour les rapports de l'apparmeur.
