不知为什么，Fedora 14下用yum安装MySQL后配置挺麻烦，现将更改密码的方法记录一下。
报错问题：
[root@www mysql]# mysqladmin -u root password 123456
mysqladmin: Can't turn off logging; error: 'Access denied; you need the SUPER privilege for this operation'
是权限的问题么？不解
解决方法：
1. 修改文件/etc/my.cnf，在[mysqld]段中加入skip-grant-tables，就是在启动打开mysql时跳过权限验证，保存退出。
2.重启mysql服务[root@www mysql]# service mysqld restart
3.登录mysql修改密码
[root@www mysql]# mysql
