使用万网提供的轻云服务器，连接MySQL数据库时提示如下信息：服务器[qdm-011.hichina.com]连接失败！
错误代号:2000
错误信息:mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool to reset your password with the command SET PASSWORD = PASSWORD('your_existing_password'). This will store a new, and more secure, hash value in mysql.user. If this user is used in other scripts executed by PHP 5.2 or earlier you might need to remove the old-passwords flag from your my.cnf file
