DNS in centos


How to configure DNS setting and reverse DNS on centos?? I am creating a hadoop cluster in which i need configure each host which contains another host so that they can communicate with each other. I suggested as an alternative to edit the hosts file on every host in my cluster to contain each of your hosts. Pls, also tell host configure host file?

you could set up a DNS server if you want, but hosts file edit is probably easiest, just open it up and add a line for each entry,:


ip.add.re.ss hostname.domain


that's it.

you can perform forward and reverse lookups on the relevant hostnames and IP's.
