How to set up Web Environment?

Question

1C-Bitrix

There is a server with Centos 7 and a Plesk panel
. I want to put the Bitrix Web Environment there, since they were honored to release a version for Centos7. I have seen the instructions. Question three - How can I see the Plesk panel, for example, through phpMyAdmin site database? In the panel, I create domains, which, of course, will no longer belong to the bitrix folder, how then to connect it?
What are pools in the concept of Bitrix environment? How do I add domain names?
And the third question - there are two more sites on WordPress - should they be added there to the Bitrix machine or to hell with them?

Answer 1

Bitrix environment is an already configured server. It is installed on a clean server, without a Plesk panel.
You already have a server with a Plesk panel, create it like a regular site and just install the CMS itself
