How to combine multiple scripts on one site?

Question

CMS

Hello guys! Please, tell me where and what material to look for to study.
The question is, I want to put an online store on the site with the ability to create a landing for each (optional) product, plus so that visitors can do this by joining an affiliate program, something like apishops.com works, also so that there is a blog, forum, own payment system and CPA. How to put it all together? Separately, in principle, I can do everything, but together? Immediately I warn Jung on this "Internet ship"

Answer 1

First you need to choose a CMS, and only then select plugins and scripts. You will not find anything ready.
Look to Wordpress or MODx.

Answer 2

There is no ready-made one, because if someone created it, it would be impossible to use it as a whole.
Choose Framework/CMF/CMS as a basis, and write custom functionality based on it, there is no other way.

Answer 3

And if you put everything on nginx and develop from it, you can also find out more about this in more detail about this, who is an expert in Runet?
