centos – Upgrade PHP to New Version

admin

My CentOS7 server has a very old version of PHP installed (v7.2.10). I am trying to upgrade to PHP8 but am having some major issues. My server has PHP Version Switcher installed and when I try to have it install PHP8, I keep getting an error

I then tried to use yum to install PHP8. It seemed to install fine but php -v still returns 7.2.10. I ran yum list installed | grep php and it returned

Running systemctl status cwp-phpfpm.service returns

So it looks like PHP 7.2 and 8.0 are both installed. How do I have CentOS use PHP8 instead of PHP7.2?
