Linux - mysqli can't be found

So piwik is telling me.


Piwik requires either the mysqli extension or both the PDO and pdo_mysql extensions.
On a Linux server you can compile php with the following options: 

--with-mysqli

--with-pdo-mysql


In your php.ini, add the following lines: 

extension=mysqli.so

extension=pdo.so

extension=pdo_mysql.so

After making this change, restart your web server. 

More information on: PHP PDO and MYSQLI.

So I have:
php 5.3.3-14
and using yum I installed php-mysql-5.3.3-14

Thing is piwik still complains.phpinfo() contains no reference to mysqli and php-m doesn’t either. I’m guessing I need to make php aware of mysqli but where?

ignore. I reinstalled a bunch of php packages and got it running.
