SOLVED DNS cluster Setup assistance needed

Hello,

Kindly need someone help me to guide me for DNS Cluster.

I read the documentation but I am confused how I must setup properly the DNS Cluster with 1 domain and multiple IPs and WHM.

I have the bellow servers:

Server1 -> Webserver + DNS
Server2 -> Webserver
Server3 -> Webserver

My configuration now is the below:

Code:

+-----------------------------------------------------------+
        Server1 - webserver

    All DNS Records (are on that server only!)
        ns1.mydomain.com (1.2.3.4)
        ns2.mydomain.com (1.2.3.4)
        ns3.mydomain.com (5.6.7.8)
        ns4.mydomain.com (5.6.7.8)
        server1.mydomain.com (1.2.3.4)
        server2.mydomain.com (5.6.7.8)

+------------------------------------------------------------+

When I have a new server I go to server1 and I add new nameservers with IPs and A records for hostnames! But if my server1 goes down then no one can see the sites from the Server2!!

I know that made a configuration as above is a big mistake!! Please can help me to understand how can I setup the DNS cluster so when I have a new server to setup under the same domain name the DNS entries?

I must setup something like this?

Code:

   
+------------------------+
  |server1 | webserver|
+-----------------------+
         |        |                               
         |        |
+-------------------------------------------------------+
       |                                                        |
+----------------------------------+           +------------------------------------+
 |              dns1                        |            |        dns2                                |
 | ns1.mydomain.com (1.2.3.4)|              |  ns2.mydomain.com (1.2.3.4)   |
 | ns3.mydomain.com (5.6.7.8)|              |  ns4.mydomain.com (5.6.7.8)   |
 | server1.mydomain.com (1.2.3.4) |       | server2.mydomain.com(5.6.7.8)|
 +-------------------------------------+       +------------------------------------+

Please can guide me what setup configuration I must do to have all my servers (and the new one) properly DNS setup?

Thank you!

 

So I must setup 2 dns clusters (propably 2 vps) and connect every dns from WHM servers there?

I must have different IPs for any nameserver?

If I must not then when for example ns1.mydomain.com have a network issue the ns2.mydomain.com will serve without any problem?

Any help and guide me is highly appreciated! I'm a bit confused with this infrastructure..

 

@cPanelMichael Thank you for your response!!

Something that I hear and I am not sure:

Is that true?

I want to have 1 domain with multiple servers! Like: ns1.mydomain.com ... ns50.mydomain.com that mean that I must have 50 vps??

I want mydomain.com to register with multiple servers (WHM).

I have 3 servers now WHM and I want to have all these 3 servers as nameserver name mydomain.com

How many vps DNSONLY I must setup? I am bit confused...

1server -> 2vps DNSONLY
2server -> 2vps DNSONLY
3server -> 2vps DNSONLY

OR

1server -> 1vps DNSONLY (synchronize with that WHM)
2server -> 1vps DNSONLY (synchronize with that WHM)
3server -> 1vps DNSONLY (synchronize with that WHM)

Please can advice?

After 50 servers I must have 50 vps with example ns50.mydomain.com OR 100 vps DNSONLY??

 

Hello,

When I firstly setup my DNS1 server I have ns1.mydomain.com (Hostname and nameserver). In step 4 when I must choose 2nd nameserver what nameserver I must input?

I must setup the same time DNS2 server as ns2.mydomain.com (Hostname and nameserver) and add for:

DNS1 -> Setup step 4 ns1.mydomain.com(DNS1 IP), ns2mydomain.com(DNS2IP)
DNS2 -> Setup step 4 ns1.mydomain.com(DNS1 IP), ns2mydomain.com(DNS2IP)

How is possible to setup 1 domain as:

Webserver 1
Webserver 2
Webserver 3

DNS1
DNS2

and all my webservers synchronize from DNS1 and DNS2 with multiple ns from the same mydomain.com?

The first setup must have the ns IP's and records from the 2 DNS only?

Also the domain mydomain.com and all records where it must setup? In one of the DNS servers or in one of Webservers?

Thank you!

 

@cPanelMichael Thank you for the response!

I must explain better my situation so you can understand what I'll try to do!

1- I have 4 different webservers with WHM. I want those 4 webservers to be connected on a DNSONLY cluster. For that purpose I have 2 VPSes at 2 different locations.

1- Question:
How I must setup the configuration of that 4 webservers with my 2 DNSONLY VPSes to succeed no downtime for the DNS perspective? I want these DNS to be setup:

1st WEBSERVER -> ns1.mydomain.com, ns2.mydomain.com
2nd WEBSERVER -> ns11.mydomain.com, ns12.mydomain.com
3rd WEBSERVER -> ns21.mydomain.com, ns22.mydomain.com
4th WEBSERVER -> ns31.mydomain.com, ns32mydomain.com

DNS1 -> ns101.mydomain.com
DNS2 -> ns102.mydomain.com

I use mydomain.com for all the WEBSERVERS and DNSONLY. Where I must add that domain and locate all the NS records?

Please can you help me because I have stuck with that configuration!

I think I have misunderstood where I must put (make account) of mydomain.com and how - where the NS records must be to have the functionality!

Only that I want is that every webserver take DNS from DNSONLY 2 vpses. I think the best configuration is to keep in those DNSONLY all the records...

Now I have mydomain.com to my 1st WEBSERVER and I keep there all the NS records! But the problem is when this WEBSERVER go down then no one can see the other 3 WEBSERVERS because the DNS is down!!!

How can configure properly the cluster so I have 2DNSONLY manage entirely records?

Thank you in advance!!!

 

@cPanelMichael Thank you!!
I try the way you told me and seems all run as I want!!

One last question:

In the DNSONLY I must enable the cluster too or it's ok if not?

I make the

with the Write Only option but in DNSONLY servers (DNS1, DNS2) I have cluster disable. I must enable the cluster and add webserver as standalone or disable is ok too?

What is the recommendation?

Thank you!

 

Yes I selected the Setup Reverse Trust Relationship so I leave the clustering in DNS-Only disable as is the same!

Thank you so much for your help!!
