MySQL 突然出現錯誤

錯誤訊息如下:


#2000 - 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

原來是系統更新到 PHP 5.3 後,MySQL 卻仍只支援到 PHP 5.2 所致。只要把 MySQL 也更新就好。
