Can not solve the problem
Thank you, hew.
I installed php-mysql parkage.
[root@linuxserver ~]# rpm -qa | grep php
php-pdo-5.1.2-5
php-5.1.2-5
php-pear-1.4.6-2
php-mysql-5.1.2-5

And restart httdp service, but still can not open a PHP test page as below

<body>
<?php
echo "This a php test page!¨;
?>
</body>
</html>
