早くて汚い方法があります
SysAdmin権限を持つユーザーを取得し、次の手順を実行します。
-
[mysqld]セクションの下のmy.cnfに「skip-grant-tables」を追加します
-
mysqlを再起動します
-
パスワードなしでmysqlと入力し、Enterキーを押します
-
これを実行します:
DELETE FROM mysql.user WHERE user = 'root' AND host = 'localhost'; INSERT INTO mysql.user SET user = 'root', host = 'localhost', password = Password('whatevernewpassword'), Select_priv = 'y', Insert_priv = 'y', Update_priv = 'y', Delete_priv = 'y', Create_priv = 'y', Drop_priv = 'y', Reload_priv = 'y', Shutdown_priv = 'y', Process_priv = 'y', File_priv = 'y', Grant_priv = 'y', References_priv = 'y', Index_priv = 'y', Alter_priv = 'y', Show_db_priv = 'y', Super_priv = 'y', Create_tmp_table_priv = 'y', Lock_tables_priv = 'y', Execute_priv = 'y', Repl_slave_priv = 'y', Repl_client_priv = 'y', Create_view_priv = 'y', Show_view_priv = 'y', Create_routine_priv = 'y', Alter_routine_priv = 'y', Create_user_priv = 'y', Event_priv = 'y', Trigger_priv = 'y', Create_tablespace_priv = 'y';
-
mysqlを終了します
-
[mysqld]セクションの下のmy.cnfから「skip-grant-tables」を削除します
-
mysqlを再起動します
これですべてです!
