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;
