Hi,
First i would like to explain my problem clearly and am beginner to Linux. I have an Dell server with redhat 5 OS. In that i have hosted one database using mysql and html+perl. It is located in /var/www/html/xxx folder. It is working fine but at present i want to host another database. That database created by using mysql and html+php. When i am moved that files to /var/www/html folder its working good with html file but the search (php) files are not working. Then tried to executing php file in command line i found error as
" PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/msql.so' - /usr/lib64/php/modules/msql.so: cannot open shared object file: No such file or directory in Unknown on line 0
PHP Fatal error: Call to undefined function mysql_connect() in /var/www/html/test_php.php on line 2 "

This php file located in /var/www/html/test_php.php. That coding is

<?php
$link = mysql_connect('localhost', 'root', 'pass');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_close($link);
?>


Php installed on server but dont know it is configured or not.
I think php configuration was wrong. Pl help me to fix this problem and where am did wrong.

Thanks in advance.

You miss the php-mysql package. As root run the following to install it

Thanks for reply. In my server Yum function not working because of RHN registration problem. I have tried to install manually ( php-mysql-5.1.6-39.el5_8.x86_64.rpm) but it was failed due to dependencies such as,
# rpm -ivh php-mysql-5.1.6-39.el5_8.x86_64.rpm
warning: php-mysql-5.1.6-39.el5_8.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID e8562897

php-pdo is needed by php-mysql-5.1.6-39.el5_8.x86_64

Then i was tried to install failed dependencies,

# rpm -ivh php-common-5.1.6-27.el5.x86_64.rpm

Is there any alternate way to use yum command without RHN registration?.

Since you're using RHEL, you should register (and pay for support) with RHN.
Anyways, if you insist not to do so, you can have a look here to see how to use a Centos repository

You could use CentOS. CentOS is a community built distribution of the RH platform.

Thanks to all.
