mysql>update mysql user set password = old_password('5201314')
      ->where host = '192.168.1.143' and user = 'root';

mysql>update mysql user set password = old_password('5201314')
      ->where host = 'localhost' and user = 'root';
error 1046(3D000):No database selected

在MySql> 命令行下输入：SET PASSWORD FOR user@localhost = OLD_PASSWORD('pw');
其中：数据库使用的用户名是user ,密码是 pw （上面的语句后面的分号不可少）
