1.Install the bind distributtion. 2.when you install the bind correctly,you will be find these files in /etc and /var/named directory! /etc/named.conf /var/named/chroot/var/named/named.ca /var/named/chroot/var/named/localdomain.zone /var/named/chroot/var/named/named.zero /var/named/chroot/var/named/data /var/named/chroot/var/named/localhost.zone /var/named/chroot/var/named/named.ip6.local /var/named/chroot/var/named/slaves /var/named/chroot/var/named/named.broadcast /var/named/chroot/var/named/named.local 3.configure the main file /etc/named.conf. in this example,the 192.168.0.98 is the dns server!domain is hhelian.com the content of the named.conf as following:
//
// named.conf for Red Hat caching-nameserver
// options {
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
}; //
// a caching only nameserver config
//
