Master/Slave PowerDNS Replication on CyberPanel
CyberPanel version v1.8.5 and above have the ability to configure CyberPanel as either PowerDNS Master or Slave. For more details visit changelogs. In this guide, we will see how to configure CyberPanel as Master or Slave.
Step 1: Configure Glue Records/Private Nameservers
Before configuring CyberPanel, you need to register Glue Records (some registrars call them Private Nameservers or hostnames) at your domain registrar. You can read this article for more details.
In this tutorial we assume that:
- ns1.cyberpanel.xyz – 192.168.100.1 (Is your Master DNS server)
- ns2.cyberpanel.xyz – 192.168.100.2 (Is your Slave DNS server)
Configure them accordingly on your domain registrar using this guide.
Step2: Install CyberPanel on both Servers
Install CyberPanel on your Master and Slave servers.
Step 3: Configure Master CyberPanel
Once CyberPanel is installed, log in to your CyberPanel dashboard and navigate to Manage Services -> Manage PowerDNS
It gives you the option to configure up to 3 slave servers. However we are going to configure only one. From dropdown select Master.
Slave Server 1 -> ns2.cyberpanel.xyz (Your value here will be different according to your slave server).
Slave Server IP -> 192.168.100.2 (IP of your slave server).
Once done, click Save Changes, your master is now configured. You need to configure your slave so that it can accept DNS queries.
Step 4: Configure Slave CyberPanel
Log into your slave CyberPanel dashboard and navigate to -> :8090/manageservices/managePowerDNS
Here you will enter two things:
Slave Server -> This is the name of the slave server such as ns2.cyberpanel.xyz
Master Server IP -> Don’t confuse it with Slave IP, you need to enter the IP of the master server here.
Once done click Save Changes.
Step 5: Confirm Replication is Working
Once all of the steps above are completed, open your Master CyberPanel and create website, now go to your CyberPanel Slave and make sure the zone is replicated there.
On slave you can also use this command to make sure that Master CyberPanel is sending notifications to slave about newly created DNS zones:
journalctl -f | grep pdns
