[webmin-l] How to make some basic configurations in virtualmin?

[elvan g. <hom...@gm...>]

Hi i am using linux ubuntu 20.04.

I installed virtualmin to my vps server. And i made basic configurations
for it during my first login to virtualmin. Best part is that it checked my
server completely and displayed the results. I really really liked it. I
will just host two websites on my vhost. For that reason, before installing
virtualmin i was doubting to install. But after seeing  its "re-check
configuration" function, i decided it is worth to install it.

But i am totally new and i need detailed guide how to use it correctly. At
least i need to find answers to my questions below:
1- how should i create a virtual server in virtualmin?

2- What will happen to my other two enabled vhost config files that i have
created via terminal. I can not say that they are completed but they are
pointing to my domain and i have made some configurations in them (like
directing non-www domain to www domain etc. ) They are: (mydomain.com.conf
and mydomain.com-le-ssl.conf) under    /etc/apache2/sites-enabled. Should i
leave them as they are and create a new virtual server in virtualmin?

3-Beside this before creating my virtual server in virtualmin, i want to
change my php version to php 8.1-fpm (i already have 8.1 but not fpm).

4- And my apache is not supporting HTTP/2. I also want to figure out this
issue before creating my first virtual server with virtualmin. How should i
do that?

Thank you.
