I installed cPanel with DNS only on CentOS 5.3.

I have WHM/cPanel license, and I am familiar with the installation and initial configuration. However, I cannot figure out how to use "cPanel wiht DNS only."

I was trying to find a documentation, but I could not find it. Does anybody know where I can get?

I typed http://localhost/ and http://localhost/cpanel, but both did not show anything.

If there is no official manual for DNS only, how can I start wizard to configure it?

Thank you.

Here is the link.

I hope this is what you are looking for.

Port 2087

Thank you very much for the link of documentation. I think I could configure the DNS server.

I am wondering if I should close the port 2087. I had to get a key from the server, and the firewall did not allow me to access the DNS server.

If closing that port does not affect any performance to synchronize records, I would like to do so.

Any idea?

Thank you.

Port 2087 is for secure WHM (DNS Only) access and not for synchronizing DNS records. It is recommended to use secure access to WHM rather than unsecured log in.

Actually, all DNS clustering commands are sent via WHM ports, so port 2087 is used for synchronizing DNS records. The user would initiate the transaction from the WHM on one server, which would then connect to the other server(s) in the cluster on port 2087 to issue the clustering commands.

In short, you do need to leave port 2087 open in order for your DNS cluster to work.

Thanks for clearing that. I never thought WHM ports were used for this.

Sounds like you may be in a little over your head ....

Anyway though, the "DNS ONLY" version of Cpanel and regular "Cpanel" are identical in the way they operate from the user perspective.

Both login to their respective WHM interfaces using:

http://x.x.x.x:2086/ (non ssl :: where x.x.x.x is your server's IP)

https://x.x.x.x:2087/ (ssl encrypted connection)

The "DNS Version" is just simply stripped of all hosting features and really only has the options and setup configuration needed to establish a cluster configuration with an actual Cpanel server someplace else.

The DNS server itself needs port 53 but you also have to have the standard Cpanel ports open in any firewall you add as well inbound whatever port you choose for SSH and outbound port 25 if you would like your server to actually be able to notify you of any problems.
