Provisionable services?

Hi all,

I'd like to setup a number of servers for hosting of domains. Instead of having every service on every machine, sharing the IPs, I'd like to have a number of specialized machines:

• A primary DNS server
• A mysql host
• nginx with fcgi-based PHP
• nginx with Ruby support via Passenger
• Apache for domains specifically needing it

I run Cloudmin on one separate master controller machine and would have Webmin on the mysql/dns ones, Virtualmin on the others. Is there a way to configure this setup in such a way that

• I can create and manage domains from Cloudmin
• domains will be using the given dns server
• Cloudmin will be smart enough to insert and maintain the correct IPs for domain MX and http

Any help is appreciated. Kind regards,

Christian
