  方法1: 用SET PASSWORD命令

    mysql -u root

    mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');

  方法2:用mysqladmin

    mysqladmin -u root password "newpass"

    如果root已经设置过密码,采用如下方法

    mysqladmin -u root password oldpass "newpass"

  方法3: 用UPDATE直接编辑user表

    mysql -u root

    mysql> use mysql;

    mysql> UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root';

    mysql> FLUSH PRIVILEGES;

    在丢失root密码的时候,可以这样

    mysqld_safe --skip-grant-tables&

    mysql -u root mysql

    mysql> UPDATE user SET password=PASSWORD("new password") WHERE user='root';

    mysql> FLUSH PRIVILEGES;
