Permssions Problem

Hi All

I have had this happen to me a few times, so hopefully someone can give me categorical support on this.

I am running a server with Centos 7.
I am the root user, as I have discovered Centos 7 is a slightly different flavour.
So when loggng in via SSH as root please can someone translate the following for Centos7 commands, or gve me guidance

Set ownership of the SuiteCRM directory:
  chgrp ApacheUser.ApacheGroup <suitecrmroot> -R recursively sets ownership for root directory to Apache user and group. 

Set the following permissions on the SuiteCRM directory(Linux):
  sudo chown -R www-data:www-data .
  sudo chmod -R 755 .
  sudo chmod -R 775 cache custom modules themes data upload config_override.php


If you are login as root user you do not need to user sudo before any command.
