Domain Name Server (DNS) Cluster Setup In Cpanel
Jul 7, 2009
Hi there, i have few question for the best suited DNS Setup for our compagny.
We have tree server located in montreal.
Two are running web services, one of them is only for dns ( home server ).
Two main server have Whm/Cpanel.
One run Cpanel Dns only.
Main server have 7 ips each
Dns server, only have 1
Let say we use domain xxx.com
Right now we have ns1/ns2/ns3/ns4 point to server1
ns5/ns6/ns7 point to server2
We have no Nameserver that point to our dns only server for now.
I'd like to advoid runing DNS Service on all of them, maybe having two slave one master would be fine. Question: What would be the best suited dns setup with my current config for best responding time and fast replication?

Currently, I run cPanel servers for my clients and also host my company website on them. However, I now wish to place my company website on a seperate system running ISP Manager, and in order to connect the servers to my DNS I presume that I would have to use DNS clustering.
Here is my question - how would I create a DNS cluster between cPanel and ISP Manager? Anyone know how?

I have started to move my websites over to my UK Colocation But would like a little guidence on what the best solution would be.
I would like to build up a Server Cluster that will handle all of my sites really and also have redundancy, so If 1 server goes down the other Web/SQL/Whatever server will be used instead.
I have websites ranging from large forums to streaming & download websites.
Should I got for a setup for example:
X Web Servers + X Database Servers
Connected to X Storage (see link below)
Connecting the Web Servers in something like a a round robin config or use a Load Balancer / Other
OR Should I setup multiple:
Web Server + Database Server + Media Server
OR another config?
Below are my current setups
Current UK Setup (Colocation)
Web Server
Quad Core, 8GB Ram, 250gb HDD Raid 1
Quad Core, 8GB Ram, 250gb HDD Raid 1 (just ordered)
SQL Server
Quad Core, 4GB Ram, 250gb HDD Raid 10
Storage Server
HP StorageWorks NAS 1200s 1TB (just Ordered)

Current US Setup (Dedicated Servers)
Web Server
Quad Core x2, 8GB Ram, 3TB HDD
SQL Server
Quad Core x2, 8GB Ram, 1TB HDD
Media Server

i have ideas about clustering server with spread country/datacenter.
example: i have 5 Server spread around the world, server 1 in US, server 2 in German, and other country for next server.
server 1 will be main server, when server 1 down, it will goes to server 2, and continue to the next server.
all site/file and other stuff will be mirror on all server.
so it will be 100% Uptime!, and never LOSS anything!.
and my question is how to do that, maybe someone expert want to share with me.

I work in a DC and am looking for a better way to deal with clients who have multiple servers hosted with us.
Heres the scenario. Client buys a server or two at the beginning, with a HW firewall or they are clustered together and require their own switch and down the road, they like what we do and want to buy more servers.
However, we've been selling other servers and the only way we would be able to accommodate them would be to run a cross connect to another cab with their new server in it. Hopefully you can see where I am going with this.
This can keep happening multiple times and with multiple clients. and eventually you can end up with spider web of cable everywhere .
My thought of doing it right but more work would be to schedule down time with a client and migrate all the HW to a new cabinet where they can grow.
Weve also been tossing around ideas like getting projected growth from clients and setting aside space for them to having dedicated cluster cabinets.
how do other DCs handle situations like this?

I´m running 4 servers on a cpanel - dns - cluster.
- 1 running cpanel (srv01)
- 3 running cpanel-dns-only (cluster01 - cluster03)
My DNS config is:
srv01 - dns1.domain.com
cluster01 - dns2.domain.com
I ´ve setup on srv01:
- cluster01 (synchronize changes)
- cluster02 (standalone)
- cluster03 (standalone)
On cluster01:
- srv01 (synchronize changes)
- cluster02 (standalone)
- cluster03 (standalone)
And on cluster02 and cluster03, I did something like that:
- srv01 (synchronize changes)
- cluster01 (synchronize changes)
- cluster03 (standalone)
And
- srv01 (synchronize changes)
- cluster01 (synchronize changes)
- cluster02 (standalone)
1. So, is that correct?
2. It seems that when I click on 'syncronize all DNS records on all the servers' only cluster01 and srv01 got all the DNS records. So is it normal?
Yet If I add a domain on cluster02 for example, where I need to add the DNS? cluster02 named.conf or on cluster01/srv01?

We have two in-house servers, one is hosting our public web server. The other one was just purchased to host a mirror of the production server (as a backup). The site is protected by an SSL cert... my question is how do i set up the server(s) so if/when the backup server needs to be switched into produciton, the SSL cert will transition flawlessly?
They are both apache 2 servers.

I have registered a domain using godaddy. I have hosted my site on a server of my shared hosting provider(lets call them X).Currently I have pointed mydomain.com to the server and it is up and running.Sometimes, I have experienced downtimes.
In order to solve this problem, I have hosted a clone of my site on another server from another hosting company(lets call them Y).
1. I want mydomain.com to point to Y when X is down
2. again point it to X when it is up.
My main aim is to have my site live with less downtime. The probability having both servers down is very less.
I dont know if it is technically feasible, just a thought out of dirty mind. I tried to google but was not able to find an answer specific to my problem.
Can anybody tell me how to achieve this through godaddy domain.
Added note, My site is not a commercial site and I cant afford large dedicated servers with clustering and failovers.

I was curious to know if it were possible to share your domain on a cluster server even if it has a dedicated IP and an SSL license assigned to it?

I have 1 server so I setup dns as ns1.mydomain.com, ns2.mydomain.com ip address pointed to server1. So, now I just bought another server. Can I setup ns2.mydomain.com pointed to 2nd server. Also how to setup more servers ie. 10, 20 server because I can only set up to 6 dns in one domain name.

I try to keep on the up and up about hosting and constantly looking for a new host to provide better services, but I saw an article in TheWHIR that got me to wonder if people are making stuff up or is it just "marketing" or real?
Ok, so the article:

I hope adding a link to the article is ok?
First of all I have NEVER heard of cPanel ever offering clustered technology. Can anyone confirm or deny that this is real? I have really only used HSphere which I know has some cluster abilities and even those hosts don't advertise "clustered" services.
Then I see other so called cPanel wannabe clustered services which they call cPanel clustered failover or something like that which to me is ummm..more fault tolerant hosting than actual cluster hosting.
Basically, am I just not understanding the meaning of "cluster"?
I think cluster has to do with the proper allocation of reasources spread across the network of defined processes, though, I have been wrong in the past...

I just signed up for dedicated server at Softlayer with cPanel, mySQL and CentOS. I'm moving a site that is on a VPS with WHM. I know that cPanel has a transfer site feature.
I was considering hiring a service to migrate my site and to harden my server. Is this necessary or should I simply move it via cPanel? Things are tight and I don't want to incur an unnecessary cost if I don't have to. I defer to the members here at WHT for your recommendations.
