DNS cluster Setup assistance needed
-
You simply are distributing the nameservers evenly across your cluster. You have the right idea. You just need to complete the work. 0 -
So I must setup 2 dns clusters (propably 2 vps) and connect every dns from WHM servers there? I must have different IPs for any nameserver? If I must not then when for example ns1.mydomain.com have a network issue the ns2.mydomain.com will serve without any problem? Any help and guide me is highly appreciated! I'm a bit confused with this infrastructure.. 0 -
Hello, Yes, you'd need to setup two servers and install cPanel DNS-Only on those two servers: cPanel DNSONLY - Documentation - cPanel Documentation Then, simply configure the "A" records for your name servers on the hosting server and at the domain registrar the way you normally would, except use the IP addresses associated with the two DNS-Only servers you have setup (e.g. ns1.host.tld with the IP address of the first DNS-Only server, ns2.host.tld with the IP address of the second DNS-Only server). When setting up the cluster, simply access "WHM >> DNS Cluster" on the hosting server, and add the DNS-Only servers to the cluster, setting the role as "Synchronize" or "Write-Only". The difference between the DNS roles is documented at: DNS Cluster - Documentation - cPanel Documentation Thank you. 0 -
@cPanelMichael Thank you for your response!! Something that I hear and I am not sure: 1 VPS with cPanel DNSONLY is 1 Nameserver.
Is that true? I want to have 1 domain with multiple servers! Like: ns1.mydomain.com ... ns50.mydomain.com that mean that I must have 50 vps?? I want mydomain.com to register with multiple servers (WHM). I have 3 servers now WHM and I want to have all these 3 servers as nameserver name mydomain.com How many vps DNSONLY I must setup? I am bit confused... 1server -> 2vps DNSONLY 2server -> 2vps DNSONLY 3server -> 2vps DNSONLY OR 1server -> 1vps DNSONLY (synchronize with that WHM) 2server -> 1vps DNSONLY (synchronize with that WHM) 3server -> 1vps DNSONLY (synchronize with that WHM) Please can advice? After 50 servers I must have 50 vps with example ns50.mydomain.com OR 100 vps DNSONLY??0 -
Hello, There's no requirement to use one DNS-Only server for each name server. You can setup as many name servers as you prefer on a single DNS-Only server, and connect as many hosting servers as you prefer to the same cluster. Thank you. 0 -
Hello, When I firstly setup my DNS1 server I have ns1.mydomain.com (Hostname and nameserver). In step 4 when I must choose 2nd nameserver what nameserver I must input? I must setup the same time DNS2 server as ns2.mydomain.com (Hostname and nameserver) and add for: DNS1 -> Setup step 4 ns1.mydomain.com(DNS1 IP), ns2mydomain.com(DNS2IP) DNS2 -> Setup step 4 ns1.mydomain.com(DNS1 IP), ns2mydomain.com(DNS2IP) How is possible to setup 1 domain as: Webserver 1 Webserver 2 Webserver 3 DNS1 DNS2 and all my webservers synchronize from DNS1 and DNS2 with multiple ns from the same mydomain.com? The first setup must have the ns IP's and records from the 2 DNS only? Also the domain mydomain.com and all records where it must setup? In one of the DNS servers or in one of Webservers? Thank you! 0 -
Hello, You can enter the same name server values across multiple servers. For instance, if you want all domains to use ns1.domain.tld and ns2.domain.tld, then you would enter those two name servers when setting up the server. Thank you. 0 -
@cPanelMichael Thank you for the response! I must explain better my situation so you can understand what I'll try to do! 1- I have 4 different webservers with WHM. I want those 4 webservers to be connected on a DNSONLY cluster. For that purpose I have 2 VPSes at 2 different locations. 1- Question: How I must setup the configuration of that 4 webservers with my 2 DNSONLY VPSes to succeed no downtime for the DNS perspective? I want these DNS to be setup: 1st WEBSERVER -> ns1.mydomain.com, ns2.mydomain.com 2nd WEBSERVER -> ns11.mydomain.com, ns12.mydomain.com 3rd WEBSERVER -> ns21.mydomain.com, ns22.mydomain.com 4th WEBSERVER -> ns31.mydomain.com, ns32mydomain.com DNS1 -> ns101.mydomain.com DNS2 -> ns102.mydomain.com I use mydomain.com for all the WEBSERVERS and DNSONLY. Where I must add that domain and locate all the NS records? Please can you help me because I have stuck with that configuration! I think I have misunderstood where I must put (make account) of mydomain.com and how - where the NS records must be to have the functionality! Only that I want is that every webserver take DNS from DNSONLY 2 vpses. I think the best configuration is to keep in those DNSONLY all the records... Now I have mydomain.com to my 1st WEBSERVER and I keep there all the NS records! But the problem is when this WEBSERVER go down then no one can see the other 3 WEBSERVERS because the DNS is down!!! How can configure properly the cluster so I have 2DNSONLY manage entirely records? Thank you in advance!!! 0 -

Hello, You'd browse to "WHM >> DNS Cluster" on each web server and add both DNS1 and DNS2 with the "DNS Role" set to "Synchronize Changes" or "Write Only". This will ensure that all zones on each web server are synced to the DNS-Only servers. Thus, even if the web server hosting "mydomain.com" fails, the DNS would still operate because the DNS is handled on different servers. Additionally, you only need to ensure "mydomain.com" is created as an account on one of the web servers, and then edit it's DNS Zone on that web server via: "WHM >> Edit DNS Zone" When editing the zone, setup the "A" records for your NS entries pointing to the IP addresses of the DNS-Only servers. Since the DNS changes are synced, those records are then automatically published to the DNS-Only servers. You will also need to go to the domain registrar for "mydomain.com" and setup the name server IP addresses for all of your name servers (using the IP addresses of your DNS-Only servers). Thank you.0 -
@cPanelMichael Thank you!! I try the way you told me and seems all run as I want!! One last question: In the DNSONLY I must enable the cluster too or it's ok if not? I make the You'd browse to "WHM >> DNS Cluster" on each web server and add both DNS1 and DNS2 with the "DNS Role" set to "Synchronize Changes" or "Write Only"
with the Write Only option but in DNSONLY servers (DNS1, DNS2) I have cluster disable. I must enable the cluster and add webserver as standalone or disable is ok too? What is the recommendation? Thank you!0 -
Hello, You can enable clustering on the DNS-Only servers and choose "Standalone" as the role, however this is not required if you selected Setup Reverse Trust Relationship when configuring clustering on the hosting servers. Thank you. 0 -
Yes I selected the Setup Reverse Trust Relationship so I leave the clustering in DNS-Only disable as is the same! Thank you so much for your help!! :) 0 -
I'm happy to see it's working well. Thank you for updating us with the outcome. 0 -
[QUOTE="net@work, post: 2396163, member: 813191">Hello, Kindly need someone help me to guide me for DNS Cluster.
I have 3 DNS Only severs that are in 3 different locations so 3 different Network Operation Centers that sync and provide DNS to cPanel Web Servers that is in a 4th Network Operation Center. Example ns1.server.com - In Seattle, Washington ns2.server.com - In Dallas, Texas ns3.server.com - In New York Area This way there will be no down time in DNS speaking. I hope this will you and others out there.0
