I am going to install Drupal 7 to my new server, I have installed all stuff that mentioned in the requirement, however I stall get the error message saying that
"...Your web server does not appear to support any common PDO database extensions. Check with your hosting provider to see if they support PDO (PHP Data Objects) and offer any databases that Drupal supports..."
After searching from the internet, I found that I need to install pdo_mysql to my server, however I can't get this stuff from the installation package, could anyone suggest the way to solve this problem?
