How to add domain to VPS via ssh?

Question

Network administration

Good afternoon.
There is a domain linked to Cloudflare.
How to add it to a clean VDS, without a control panel and other things?
OS doesn't matter.
Thanks in advance for your reply.

Answer 1

Add virtual hosts to nginx or apache like this : devacademy.ru/posts/nginx-ubuntu-1404

Answer 2

Nothing needs to be configured on the VDS, except for adding domain aliases in the nginx or Apache config.
On a third-party DNS service (including Cloudflare), A-records from the server IP are indicated.
