I bought myself a second computer as my home server and installed ubuntu server 20.04. I also purchased a dedicated IP from my provider. My server is connected via a router, I gave it a static IP 192.168.5.5 inside the router's network and configured port forwarding.
I checked that according to my IP that the provider gave me, you can now see my site that I launched for the test.
Next, I plan to buy several domains and create several small sites on my server. I would also like to be able to use subdomains.
I have absolutely no experience in setting up servers, what should I do? Perhaps there are articles that fit my purpose? I hope for your help
