Hi
I have 3 CPANEL servers srvA, srvB, srvC and 2 VPS which use DNSonly
I want to enable DNS cluster so I am doing the followings :
I use a domain for DNS purposes lets say that be dnsdomain
For this domain I will use 2 IPs as ns in two diferrent VPS and there will be installed DNSonly
So my confing will be :
srvA stand alone CPANEL
|----- >dns1srv.dnsdomain ( DNS VPS1 ) synchronize mode
|---->dns2srv.dnsdomain (DNS VPS2 ) synchronize mode
In my registar as registared name server I will use
ns1.srvAhostname
ns2.srvAhostname
dns1srv.dnsdomain
dns2srv.dnsdomain
srvB stand alone CPANEL
|----- >dns1srv.dnsdomain ( DNS VPS1 ) synchronize mode
|---->dns2srv.dnsdomain (DNS VPS2 ) synchronize mode
In my registar as registared name server I will use
ns1.srvBhostname
ns2.srvBhostname
dns1srv.dnsdomain
dns2srv.dnsdomain
srvC stand alone CPANEL
|----- >dns1srv.dnsdomain ( DNS VPS1 ) synchronize mode
|---->dns2srv.dnsdomain (DNS VPS2 ) synchronize mode
In my registar as registared name server I will use
ns1.srvChostname
ns2.srvChostname
dns1srv.dnsdomain
dns2srv.dnsdomain
etc
Questions :
- This configuration its OK or for every server need to use different VPS DNSonly ?
- If my main server fails example srvA my DNS records still to reported by dns1srv and dns2srv with this way avoiding service failures; as example www service serviced by other server, mail server by other server ?
- If my srvB fails and all services hosted there what happens when someone sends me an email ?
I will loose it or I will get it when my srvB is online again ?
