Setting up multiple linux servers

Looking for some help on redundancy, DNS, backups etc...

Hi there,

I have a couple of linux servers and am looking for some FAQs or whitepapers to see how they could be setup to back each other up and provide some DNS redundancy.

Any tips?

Regards,

What services are you trying to make highly available?

is an interesting way of having two servers back each other up, though you don't achieve load sharing.

Are you sure you read the article thoroughly, round-robin DNS provides load balancing as in:

Once Pinky and Brain have their respective eth0:0s set, bind a service (like Apache) to their aliased IPs, and set up round-robin DNS to point to both with a single hostname.

Now that roughly half of the traffic is going to each server, we'll need Pinky and Brain to monitor each other's health.

Doh!

I just pulled the title from memory and googled for it. Forgot about the exact details. Thanks for pointing that out.

Looks like its going to take more than my current level of expertise if its going to be done on live servers. :)
