DNS Cluster Setup with cPanel DNS Only

[Sindre]

Hello,

I have read a lot on this topic, but still think it is somewhat confusing so want to ask to be sure.

I have a couple of web servers running cPanel. I am also running 2x cPanel DNS Only in VPS.

I want to enable DNS clustering.

So far I have figured out the following configuration:

WEB SERVER 1:
-> DNS ONLY1 "synchronize"
-> DNS ONLY2 "synchronize"

WEB SERVER 2:
-> DNS ONLY1 "synchronize"
-> DNS ONLY2 "synchronize"

cPanel DNS ONLY 1:
-> WEB SERVER 1 "standalone"
-> WEB SERVER 2 "standalone"

cPanel DNS ONLY 2:
-> WEB SERVER 1 "standalone"
-> WEB SERVER 2 "standalone"

I think I got this part correct?

What I want to know is: do I have to add cPanel DNS ONLY 1 to the cluster config on the other DNS server and vice versa? Or will zones automatically synchronize between the DNS servers in the cluster?

And: should I add each WEB SERVER to every other web server cluster config?

I am pretty sure I should only add the DNS servers on the cluster config for the web servers, and only web servers on the cluster config for the DNS servers, but I want to be sure.

Thank you,
Sindre

Hello

The current configuration you have in place is valid.

do I have to add cPanel DNS ONLY 1 to the cluster config on the other DNS server and vice versa? Or will zones automatically synchronize between the DNS servers in the cluster?

No, you do not need to synchronize DNS-Only servers to each other, or configure them in the cluster together at all.

And: should I add each WEB SERVER to every other web server cluster config?

No, you do not need to synchronize the web servers to each other, or configure them in the cluster together at all.

Thank you.
