mysql数据库root权限怎么改？

现在的情况是root并不是超级用户，输入命令mysqladmin -u root password 'abcde'设置root的密码
会出现mysqladmin: Can't turn off logging; error: 'Access denied; you need (at least one of) the SUPER privilege(s) for this operation'
如果输入mysql> FLUSH PRIVILEGES;更新权限会出现
ERROR 1227 (42000): Access denied; you need (at least one of) the RELOAD privilege(s) for this operation
