The best way is, find a trusted third-party yum repository which provides Apache-2.4, PHP, then upgrade. But i don't know which one provides it.
Another way is building RPM package yourself by following Apache official guide: https://httpd.apache.org/docs/2.4/platform/rpm.html
Just curious, why you want to upgrade to Apache-2.4 and PHP-5.4? Any special features you expected?
Hello, Zhang! Thanks for the quick answer.
I forgot to mention that I didn't find any (working) yum repo with Apache 2.4 (don't understand why).
I guess I'll have to take your suggestion and build it from source.
Do you think it's worth trying to modify the installer to install those versions from the start??
In this moment, I need to upgrade those for benchmarking purposes. I'm lauching a web app and I heard that apache 2.4 is much faster but that I should try it with my own app to know how much faster. I could just install them and test but I'd like to see how my server would behave while using everything that I'll have in the real server and that will probably include iRedMail (if I can solve this issue).
Thanks once more!
