% mysql -uroot
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

となってしまい、rootでmysqlにアクセスできない場合に、データを全て消して再インストールしたい。

  • 方法
% brew services stop mysql
% pkill mysqld
% rm -rf /opt/homebrew/var/mysql
% brew postinstall mysql
% brew services restart mysql

これで問題なく、rootでログインできました。

% mysql -uroot
