Have you added the optional epel repo? You might have other external repo that conflict with higher priority.

when i try to check the version after instalation php8 wasn't found php -v
-bash: /usr/bin/php: No such file or directory

The new binary is php80

This new binary name also means tools like composer will not work. Before you go to install it, you'll need to alias PHP so the environment resolves it:

ln -s /usr/bin/php80 /usr/bin/php

What's the new Apache module?

I don't use the Apache module, which is not the most performing integration.

You can use php80-php-fpm as cgi wrapper, with either apache or nginx.

Not sure about the built-in module

Turns out the new mod_php is php80-php in this repo.

I haven't really been in an environment where a more performant server is needed, until you're just doing a completely different architecture altogether (i.e. microservices).
