Your PHP installation appears to be missing the MySQL extension which is require

Question:

I installed LAMP at AWS EC-2.

But I couldn’t install WordPress with this message

‘Your PHP installation appears to be missing the MySQL extension which is required by WordPress’

What should I do? As per the message on my site (This page is used to test the proper operation of the Apache HTTP server after it has been installed. If you can read this page, it means that the Apache HTTP server installed at this site is working properly.
