One public IP multiple servers

[slacker_au]

Hi all,

I dont know if this is possible with DA but i thought i would ask anyway.

I would like to setup a network where there would be 1 public IP address and multiple servers behind it.

The reason for this is that we are launching a free product and would like the ability to load balance multiple servers with no downtime for the customers.

I did have a go at the whole cluster function in another control panel but found that the DNS held in most ISP's for over 1 hour which caused downtime for the site we tested.

Dose anyone know if this sort of option is available with DA? and if so where to get more information from.

Regards,

James

That is not possible with DirectAdmin at the moment.

I know some have created a clustered solution based on DirectAdmin, but it would require some significant work. Especially in regards to handling e-mail. I'm not entirely sure, but you could search the forum for more in depth information about this.

DirectAdmin offers the possibility to use pre and post create bash scripts. So if you start building it yourself, that would be a start to look at.

You don't do something like this with simply a control panel. Any control panel doing something like this is also a load-balancer.

A load-balancer is a separate machine in front of your other servers. And then, as getUP points out, that's only a start. You need separate IP#s on each DA server, and your load balancer has to rewrite headers in both directions; it becomes a single point of failure.

Email, as getUP points out, and dynamic content, or both a bit complex; for dynamic content you probably need a separate MySQL server to serve all MySQL requests for the cluster; also a single point of failure.

This is the sort of setup that Netflix (for example) uses. They were down almost a whole day earlier this week.

Stuff happens even after spending millions on load balancing and high availability.
