Optimal configuration of DNS Clustering for 3 linux servers running WHM/cPanel
Posted on 2005-05-15
Just signed up to EE premium service - here's my first question...
I've got 3 linux servers running WHM/cPanel. WHM says:
"Dns Clustering allows you to get keep records synchronized across multiple servers. This system replaces the old Dns Master system used in previous versions."
What is the optimal configutation for DNS clustering across > 2 servers?
If my 3 servers are A, B, and C, which of these options is preferred:
a) Add B and C to A; add A and C to B; add A and B to C
b) Add B to A; Add C to A
If I wer a 4th ser91c
a 4th server, D, then with option b) all I'd had to do would be to add D to A and I'm done. With option a) I'd have to add A+B+C to D, then I've have to visit A, B, and C in turn in order to add D. So option b) certainly seems preferable from a maintenance point of view, so does it make it correct?
