CentOS 7.2, PHP 5.4 - MySQL extension is missing [closed]

Question

I'm trying to install a Wordpress blog on my Linux server (CentOS 7.2), using PHP 5.4 and MariaDB, but I keep running into this error:

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

Have been searching around for posts related to this:

• CentOS Linux 5.4 -Your PHP installation appears to be missing the MySQL extension which is required by WordPress
• Error when install Wordpress with mariadb "Your PHP installation appears to be missing the MySQL extension which is required by WordPress."
• Installing Wordpress in Rails /public - missing mysql extension

However, I already have php-mysql installed:

And I have the MySQL extension configured for php.ini:

But for some reason, the MySQL extension still isn't loading in phpinfo():

That's probably causing this error from Wordpress, any idea what might be happening? Why isn't the MySQL extension getting loaded in PHP? Maybe because I'm using MariaDB?

And here's the output of:

ls -l /etc/php.d , rpm -ql php-mysql and ls -l /usr/lib64/php/modules/

And the mysqli extension is installed and enabled:

Answer 1

Alright... finally, so it turns out all I needed to do was restart PHP-FastCGI. Yay.

systemctl restart php-fastcgi.service

Answer 2

Modern PHP applications use the mysqli extension which supersedes the insecure (and now deprecated) mysql extension. This should be enabled by default when you install the php-mysql package but you can check it by running:

$ cat /etc/php.d/mysqli.ini

; Enable mysqli extension module
extension=mysqli.so

To be sure that this module is enabled, check that this module is listed in the PHP info page that you showed a sample of. Note that it’s listed further down the page in the modules section.

If you have the PHP command line interface installed (from the php-cli package) you can easily check by running php -i | grep -i mysqli. This should include the following line:
