Multiple Server Setup

[Hawker]

First I'll qualify this topic.... I know ISPConfig won't manage 2 servers on 1 installation.

However I have someone who would like their own dedicated server on my system using my DNS. So I thought about it and came up with this solution...

On my ISPConfig main server set up their web site pointing to an IP that is not on my main machine. Set the mail and MX records for that new machine to that same IP.

Set up another server with ISPConfig using the above IP address. The NS records on that machine would point back to my DNS ns1 and ns2.

Would this work?
Would all email show as coming from their server and not mine?

I know these are simple questions, but sometimes simple just isn't simple. And I hope I was clear enough with what I want to do.

Would this work?yes, I have such a setup.
Would all email show as coming from their server and not mine?Without modifying postfix, mail always is sent from the systemname.primarydomain.tld, which you used during installation. That's no problem. The ISPConfig setup takes care of proper sending emails. Only when you do 'show headers' you will see the system name. But you will probably see a lot of other system names also, through which the email has traveled before reaching it's destination. That's the way email works.

Thank you!

I have dealt with dedicated servers for years, but they were leased and came pretty much ready to go out of the box so to say. I am enjoying doing the work on my own and still have a learning curve to go through.

ISPConfig is a god-send.

Okay... My question...

Iv got 2 servers, 1 static IP. How do I go about setting up 2 ISPConfig Servers here? Iv already got one ISPConfig server setup, and I would like to have a second server setup to have a diffrent set of software installed (Mysql 4, PHP5, and the such) so that I can run SugarCRM. If any one can help me, Id really appreciate it.

Have a look at the perefct setup guides here on howtoforge.com, they are also available on the ISPConfig documentation page. they describe in detail how to setup your server for ISPConfig.

I think the bottom line question is 1 external IP with 2 servers. Maybe with configuring a proxy you might be able to manage part, but it's far from ideal. And for mail you'd need to configure trusted relays et al. It will require very careful planning and some things will probably not work. It's much better to have (at least) two public IP's. It will be a requirement as soon as you want to start using SSL certs anyway.......

Take a look here: http://www.howtoforge.com/ispconfig_dns_godaddy
It shows how to set up secondary DNS records with ISPConfig.

It shows how to set up secondary DNS records with ISPConfig.

Hi falko,

Im aware that the secondary dns is setup and a tranfer on the same server and how to setup the secondary dns in ispconfig.

However what if i wanted to setup a backup server for the primary server which carries both primary and secondary dns servers.

I wan tto literaly create another hardware server as the backup server that takes over from the primary server is it goes down...

falko this why i ask becuase i did a test on my domain and it comes up with this...

WARN Single Point of Failure WARNING: Although you have at least 2 NS records, there is a chance that they may both point to the same server (one of our two tests shows them being different, the other is unsure; it appears that there are one or more firewall(s) that intercept and alter DNS packets (some versions of Linux reportedly have a built-in firewall that does this, too)), which would result in a single point of failure. You are required to have at least 2 nameservers per RFC 1035 section 2.2.

I think the best way would be to copy the named configuration to your backup server with rsync by a cronjob.
