Is it possible to install 3 sites on bitrix web environment?

Question

1C-Bitrix

Good afternoon. Please tell me what software to use on VPS (regru)? There will be three sites on two domains. One on adobe muse, two on Bitrix (multi-site).
I’m considering two options so far, but I’m not strong in this matter, so I want to hear the advice of those who know.
1. Install on vps CentOS6 x86_64
2. Install bitrix web environment.
Here I read that on the web environment, sites on Bitrix work faster, but someone, on the contrary, obscenely hides the web environment.

Answer 1

1) It is quite possible to do it on the environment, only there are old versions of PHP, MySQL and it seems impossible to update them, otherwise everything will fall down. Plus it is necessary to install separately FTP, users. Working with the environment via SSH.
2) You can install VestaCP (free) and it will install everything you need to run sites on VPS. Read about the settings for bitrix on their forum and fix the configs.
I would choose option 2

Answer 2

And they (Bitrix and muse) must be spinning on the same server?
Bitrkis should always be installed on their reference web environment. You yourself do not set up a server like that. The best option is to buy cloud hosting with 6th centos and deploy www.1c-bitrix.ru/products/env/ on it. And let adobe muse spin on a separate wheelbarrow.
