Hi I just installed primary dns server now want to install new slave server so that in case if primary fails secondary can take requests.

Pls give practical and easy solution no links

Hello,

You already have some years here at LQ so you should know by now that nobody here will give you a ready made solution or hold your hand. YOU need to install what you need to have DNS failover and when encountering problems, then you come to LQ.

Practical and Easy?

OK, get a load balancer which will cost you a lot of money, set your databases up to sinc between each other, look at Google for possible load balancers or contact your favorite datacenter.

Really, I don't quite get it why you want to set up your own DNS failover. You'll need at least more then two servers in different physical locations, preferably connected to different ISP, to have some real advantage since your servers will depend at one point or another on the ISP ones and will only reflect their cache. If your primary goes down it'll take between 5 minutes and several hours for your other server to catch up if you only have two.

No links?

Well, sorry, but here's one: Failover dynamic DNS with bind and DHCP.

If you don't have the experience nor the knowledge to perform a task don't expect us to hold your hand and provide step by step guides. Instead get on Google, research and try.

Kind regards,

Eric

So, you are going to slave this server off your primary, purely in order to cope with the condition that the primary goes down.

An easy solution for me is to tell you to read the book DNS and Bind. A famous online encyclopaedia has a useful page, but you will not allow me to give you a link.

A slave DNS is rather easy to set up. There are plenty of how to documents on the web. That is what I did when I set up my DNS servers. Each one acts as a primary for some zones and as a slave for the other's primary zones.

Edit: I want to follow up on this thread. Specifically, rather than making a rude response about using a search engine, I would like to address the statement made by the OP as after reviewing other posts, I see that there may be an issue with general communication style.

@sunlinux, the problem is that this statement comes across as though you expect someone to do the work of implementing a slave DNS setup and handing you their work and that you don't even want to be bothered to put forth any effort towards finding your own solution. I have a hard time accepting that this is your intent.

So, on that note, I will ask: what do you have so far? What DNS application are you using (e.g. Bind)? What is its state of functionality. Have you tried to implement a slave DNS? What documentation are you following? Please provide specifics.

Also, I would like to know why you are stipulating that you don't want any links? Unfortunately, a lot of times this is the very best way to direct you towards a solution. Giving you a link to an example of what has worked in the past or what we have found to work.

I myself spent 20-30 hours getting a slave DNS setup working properly. As I have demonstrated in many posts in the past, I am willing to share my configuration information. I am not, however, going to just hand my work to someone because they demand it. In addition, a DNS solution will need to be customized to YOUR system. This is not something someone can just hand to you. You will need to do that part yourself.
