is there any tutorial for creating shared hosting using DO VPS ?

because i’ve tried first using zpanel etc but have problem in email (sometimes it doesnt send / receive the email), also have problem in private nameserver setting (i still not 100% understand about sett private ns for DO. also have problem because i need to add domain in DO every time client add domain in the Control Panel).

If there’s any complete tutorial (or simple but i can understand, using any free control panel for vps like sentora, centos cp, etc) without any problem like above, please share :)

Thank You
