In order to install PHP with MySQL support you first need to install mysql, mysql-lib, mysql-server and mysql-devel. Install instructions for MySql libs.
Also you may need to install libxml2-devel in order to get xml2-config.
yum install libxml2-devel
Finally generate the makefile:
./configure –with-apxs2=/opt/apache/bin/apxs –with-mysql –prefix=/opt/php
And compile PHP:
make
make test
And install it
make install
And finally install php-mysql
yum install php-mysql
You need to make sure all these lines are found in httpd.conf:
LoadModule php5_module modules/libphp5.so
<Files *.php>
SetOutputFilter PHP
SetInputFilter PHP
</Files>
AddType application/x-httpd-php .php
