How to host a website on a private server, to be accessed from the Internet using Open Server?

Question

open server

In general, I have a website (written in PHP) and a static IP address in my hands. I need to place Open Server on a private computer, upload my website to it and bind a static IP to my website in the server settings. Do I need to do anything else to make the site and server work correctly?
PS
The site was written by myself. My knowledge is limited to the Open Server documentation, so I don't know all the ins and outs of the setup.
