Setup Two DNSonly to Cluster Nameservers with cPanel Server?

Frankenstone
Hey Guys, setting up the servers with running whmcs are done. I have no my shared server 1 called c1 here and my ns1 and ns2 dnsonly server. I've changed the nameservers on my domain to my own ns1. and ns2. and registered the private nameservers @ the registrar. Now i want to setup these 3 servers to a working dns cluster. I think the recommended option is to let the c1 sync to ns1, ns1 as write only from c1 and ns2 as standalone connected with ns1. What would u say? Would this work like i think or did i have to setup another way? Are the rights from the API enough/too much for this? Some Tutorials say i should create a ssh key without a password but...sry what?^^ (i dont think that this is possible^^) Thank you in advance. Greetings

    Hello,
    I think the recommended option is to let the c1 sync to ns1, ns1 as write only from c1 and ns2 as standalone connected with ns1.

    This sounds almost like a daisy chain type of configuration and that is not the most recommended option. You might find our knowledgebase article here helpful: Guide to DNS Cluster Configurations - cPanel Knowledge Base - cPanel Documentation Our documentation on DNS clustering can be found here: DNS Cluster - Version 76 Documentation - cPanel Documentation Please let us know if you still have concerns/questions once you've read those! Thanks!

    Hey Lauren, thank you for ur help! We've setted up like recommended way now. My domain is already changed to the new nameservers since yesterday, the 10. january 19' 6pm and the nameservers are registered at the same registrar where the domain is registered. While the installation process of CPanel it should already have open the default ports which are called in /etc/firewalld/services/cpanel.xml over the step where u have to run the script: /usr/local/cpanel/scripts/configure_firewall_for_cpanel - right? I created my own TLD as User Account and wanna setup WHMCS with LE their, but cant, cauz the domain isnt reachable. Can u tell me how i can find the problem? DNS Servers are not my favorite part of a server setup and sure - i can just read logs - but eventually CPanel has any way to find the problem faster than reading systemlogs? Output list firewalld services/ports: [root@c1 ~]# firewall-cmd --list-ports [root@c1 ~]# firewall-cmd --list-services ssh dhcpv6-client cpanel [root@ns1 ~]# firewall-cmd --list-ports [root@ns1 ~]# firewall-cmd --list-services ssh dhcpv6-client cpanel [root@ns2 ~]# firewall-cmd --list-ports [root@ns2 ~]# firewall-cmd --list-services ssh dhcpv6-client cpanel
    A easy dig domain.tld saying "status: SERVFAIL" - but if i do a dig with +trace its showing ";; Received 12 bytes from 213.133.98.98#53(213.133.98.98) in 0 ms". And thats one of the three IP adresses from Hetzner nameservers which standard in the resolv.conf - did i need to change the resolv.conf on c1/ns1/ns2 to the IP addresses of my own nameservers? Thank u in advice. Best Regards Frankenstone

    solved! While creating the user for our own domain (where the fqdns for our servers came from and would be our company site) its loaded old dns entrys. CPanel resolved the nameservers to a old ip-adress. So i think the changes just wasnt flushed globally. After changing manually in CPanel to new nameserver IP adresses its resolving perfect! Thank u for ur help Team! Great Software!
