What version of Red Hat 7.5 Enterprise will be sufficient to raise the web server?

Question

Apache HTTP Server

Good afternoon, I want to practice deploying and configuring a web server on RedHat (i.e. minimal, without GUI, etc., just a console),
I installed Virtualbox and I'm thinking about the image of the operating system ... but I got confused

As I understand it, at least server, but which one

rhel-atomic-installer-7.5.0-1.x86_64.iso 1.07 GB
rhel-server-7.5-x86_64-boot.iso 533 MB - больше похоже на правду
rhel-server-7.5-x86_64-dvd.iso 4.30 GB - не похоже на правду, больно большой
rhel-server-rt-7.5-x86_64-dvd.iso 284.59 MB - не знаю, что значит rt
supp-server-7.5-rhel-7-x86_64-dvd.iso 498.71 MB

Answer 1

boot.iso - for download and installation, but almost everything will be downloaded from the repository. Also boot.iso is useful as a rescue diesk
dvd.iso is a complete installer, for offline installation of
rt - for real time, you hardly need
supp - maybe supplimentary, additional packages.
That is, choose either boot.iso or dvd.iso.
and 4.3 GB is fine, why do you think Enterprise Server should be small..
