Bind is not available for your system

[MoreDakka]

Hello everyone.

I installed cPanel DNSOnly on Azure Ubuntu 20.04.1. We need to use bind to have another service write to these DNSOnly servers but I'm getting this error in the Nameserver Selection screen:

"Bind is not available for your system. Please choose another nameserver configuration."

We have other Azure boxes on CentOS7 that are running cPanel DNSOnly using Bind so assumed this would work with another OS.

This is a fresh install.
Bind is installed and running on the system.

# cat /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4
#

# /usr/local/cpanel/cpanel -V
110.0 (build 5)
#

Any ideas or need more info to help?

Thanks!

Hey there! While you can use DNSOnly on Ubuntu, it does need to user the PowerDNS nameserver option, as you wouldn't be able to use BIND on Ubuntu. If you switch to PowerDNS, the installation will complete normally. Can you try that?

Hey cPRex,
Is there a reason that DNSOnly isn't going to use Bind? What's the next best OS that includes Bind for DNSOnly?
Unfortunately I'm trying to get Plesk to write to the cPanel DNSOnly nodes. Where it does work, it needs BIND to work.

You'll want to use AlmaLinux 8 if you have to use BIND.

Ahh booo, why does DNSOnly hate Ubuntu bind so much?

 

[cPRex]

in general, BIND is pretty ancient at this point, and PowerDNS has much better performance. It may not be noticeable for most users, but on larger systems with thousands of DNS records, it can be substantial. In the future, I wouldn't be surprised if we removed BIND support entirely.

Since I'm trying to make this azure sub as cheap as possible for multiple spread out DNS servers, the Alma linux install costs extra bucks in Azure.
I see that Rocky Linux is supported and has a free model within Azure. Does Rocky Linux support Bind?

Thanks!

RockyLinux is still experimental in version 112, so I can't officially recommend that for a production environment:

System Requirements for Rocky Linux | cPanel & WHM Documentation

This document describes the system requirements for your cPanel & WHM installation on a Rocky Linux™ server.

Rex,
Jumping back to this. I'm trying to deploy this in Azure. Ubuntu is the only choice as:

Rocky Linux - Experimental
AlmaLinux - Extra Fees
CentOS - EOL
CloudLinux - Not in Azure

Is there any way to force WHM/cPanel to use Bind in Ubuntu?

 

[cPRex]

No, there is no way to get that working with Ubuntu at this point.

 

[MoreDakka]

Ha, I keep coming up with questions for this:
Our WWW servers are running Bind. If we replace all our NS servers with PowerDNS will we have to update the WWWs to match?

 

[cPRex]

There's nothing wrong with asking questions!

In general, no. The only time that is required is if you're using DNSSEC, as that required PowerDNS. Details on that are in the top red warning box here:

DNS Cluster | cPanel & WHM Documentation

This interface allows you to configure a DNS cluster and add servers to an existing DNS cluster.
