It’s just my home servers, and I love to use cutting edge software. Thanks a lot for your reply BerndH! Frankly, I’m quite new to Linux, though I have quite a lot of programming experience in Windows. Thanks again and good luck!
You can use the RH software collections (official supported). We’re using RHEL7/Centos7 and installed successfully supported PHP7 / Apache 2.4. NC is running fine.
It’s a little bit ricky with software collections but you can also install multiple PHP versions.
We’ve choosen this way because we don’t want to install packages from 3rd party repos (although Remi would be the first choice in case we change our mind).
I would highly recommend using something like Virtualmin to run your hosting. Virtualmin lets you easily switch versions of PHP between Virtualhosts. It’s also great at automatically applying Let’s Encrypt certs, which is great.
