Disini tidak akan dijelaskan apa itu DNS, silahkan cari di internet arti dari DNS. Sebelum mulai konfigurasi bind9 di Fedora 17 terlebih dahulu install software-software yang dibutuhkan.
yum install bind-utils bind
catatan :
domain yang akan digunakan web.lokal dengan IP 192.168.1.1
Konfigurasi
generate terlebih dahulu rdnc key dengan perintah
rndc-confgen
lalu tambahkan
zone "web.lokal" IN {
type master;
file "/var/named/web.lokal";
allow-update { none; };
};
zone "192.168.1.in-addr.arpa" IN {
type master;
file "/var/named/192.168.1.rev";
allow-update { none; };
};
dibawah
zone "." IN {
type hint;
file "named.ca";
};
sekarang buat zona untuk konfigurasi domain web.lokal yang terletak di /var/named/web.lokal
$TTL 86400
@ IN SOA web.lokal. root.web.lokal. (
2012071101 ; serial
1H ; refresh
1M ; retry
1W ; expiry
1D ) ; minimum
@ IN NS ns1.web.lokal.
@ IN A 192.168.1.3
ns1 IN A 192.168.1.3
@ IN MX 5 mail.web.lokal.
mail IN A 192.168.1.3
WWW IN A 192.168.1.3
dengan cara diatas maka domain web.lokal akan diarahkan ke IP 192.168.1 tetapi ip belum di reverse ke domain web.lokal untuk membuat reverse dns, buat file /var/named/192.168.1.rev yang berisi
$TTL 86400
@ IN SOA web.lokal. root.web.lokal. (
2012071101 ; serial
1H ; refresh
1M ; retry
1W ; expiry
1D) ; minimum
@ IN NS ns1.web.lokal.
3 IN PTR web.lokal.
langkah terakhir tambahkan
domain web.lokal
nameserver 192.168.1.3
di /etc/resolv.conf, letakkan pada bagian paling atas. restart bind
service named restart
bila tidak ada error hasil eksekusi perintah /bin/systemctl status named.service kurang lebih seperti dibawah ini
named.service - Berkeley Internet Name Domain (DNS)

untuk melihat hasilnya gunakan perintah dig a web.lokal @localhost hasil eksekusi perintah diatas kira-kira

coba ping ke IP 192.168.1.3

berhasil, sekarang coba ping ke alamat domain yang baru dibuat

berhasil juga, berarti konfigurasi DNS Server di Fedora 17 telah berhasil :) kedua cara ini bisa berjalandi 32 bit dan 64 bit.
