Let me introduce you guide about deployment of Drupal 7 on VDS/VPS with Caddy web-server. Assume that server has about 500 megabytes of RAM and Rocky Linux 8 is pre-installed (most likely, it will be the same under Alma or Oracle). In my opinion RHEL 9.x family is too "heavy" for such setup.

Since we are talking about VDS/VPS console commands most likely will be executed as root, so there will be a # sign in examples. If you are not root, then most or even all commands must be led by sudo.
