The VM PowerDns is a TemplateVM clone.
See the installation of TemplateVM.
The status of selinux is 'permissive'.

@reboot root setenforce 0  

January 26 ,2025.  
This is  the RedHat version 9.5  
pdns-4.8.4  
pdns-recursor 4.8.9  
MariaDB-server-11.6.2  
php 8.4  
poweradmin 3.9.0  
It's not apache but nginx  

I do not recommend installing VM PowerDns in the same Lan
as your company. The network administrator might not like it.
I isolate my VM PowerDns with pfsense or ipfire.

This procedure is based on this example.
Dns1 server ip :   192.168.90.41/24
Gateway: 192.168.90.254
Domain: ol26modk.com
Dns1 Server name: dns1.ol26modk.com

vi /etc/hostname

dns1  

At the prompt you will have:<username>@dns1.

This file is consulted before access to the internet.
vi /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4  
192.168.90.41  dns1.ol26modk.com  dns1  

vi /etc/sysconfig/network

 # Created by anaconda  
# # Created by anaconda  
 networking=yes  
 HOSTNAME=dns1.ol26modk.com  

Change Network.
Example:
IP: 192.168.90.41/24
Gateway: 192.168.90.254
Name Server: 1.1.1.1
Search domain: ol26modk.com
nmcli con mod eth0 ipv4.method "manual" ipv4.addresses 192.168.90.41/24
nmcli con mod eth0 ipv4.gateway 192.168.90.254
nmcli con mod eth0 ipv4.dns 1.1.1.1
nmcli con mod eth0 ipv4.dns-search ol26modk.com

Read the new network configuration.
more /etc/NetworkManager/system-connections/eth0.nmconnection

Apply the new network configuration.

ifconfig eth0 0.0.0.0
systemctl restart NetworkManager
ifconfig eth0

Update.

RedHat may ask you to make a new subscription.
subscription-manager register --username <username> --password <password> --auto-attach --force
