Introduction
The DNS nameserver service manages the DNS zone file on a cPanel server. Reloading or restarting can refresh zone files. cPanel will automatically perform these actions in the API when you make changes but if you wanted to reload or restart manually this is possible without rebooting the whole server.
Procedure
If using BIND you can reload all zones with the command:
/usr/sbin/rndc reload
You can also reload a specific zone with the command:
/usr/sbin/rndc reload $zonename
If you want to restart BIND use the following command:
/scripts/restartsrv_named
If using PowerDNS you can reload all zones with the command:
/usr/bin/pdns_control reload
You can reload a specific zone with the command:
/usr/bin/pdns_control bind-reload-now $domainname
If you want to restart PowerDNS use the following command:
/scripts/restartsrv_powerdns
Note: If you reload all zones or the individual you don't need to restart the servers as the reload is parsing the current or latest records into memory.
