dns server
Bikin DNS Server sederhana
Pertama sekali mesin kita uninstall dulu paket paket bind dengan perintah :
[root@ns1 ~]# for a in $(rpm -qa | grep ^bind); do rpm -e –nodeps $a; done
warning: /etc/rndc.key saved as /etc/rndc.key.rpmsave
[root@ns1 ~]#
Lihat apakah masih ada paket paket yang ada didalam sana ??
[root@ns1 ~]# cd /etc/
[root@ns1 etc]# ls -l|grep named
-rw-r–r– 1 root root 1754 Jul 30 19:05 named.conf
-rw-r–r– 1 root root 1323 Jul 30 17:48 named.conf~
-rw-r–r– 1 root 25 386 Jul 29 20:47 named.conf.rpmorig
-rw-r–r– 1 root root 1323 Jul 30 05:13 named.conf-savedefault
[root@ns1 etc]#
Kita buang aja
[root@ns1 etc]# rm -f named.conf named.conf~ named.conf.rpmorig named.conf-savedefault
[root@ns1 etc]#
Kita cek lagi apakah sudah kosong atau belum ?
[root@ns1 etc]# ls -l|grep named
[root@ns1 etc]#
Kita cek paket bind apakah masih ada
[root@ns1 etc]# rpm -qa|grep bind
ypbind-1.17.2-3
[root@ns1 etc]#
Udah ga’ ada lagi sekarang, dan kita buang file yang berada di dalam folder /var/named/ dan juga kita buang namednya juga.. kita anggap semuanya ga’ ada
[root@ns1 named]# rm -rf /var/named/
[root@ns1 named]# ls
SEKARANG KITA MENGINSTALL PAKET
YANG DIBUTUHKAN OLEH DNS SERVER
Anda bisa download.. yang dibutuhkan adalah :

Bisa dilihat apa apa yang telah di delet sebelumnya yaitu pada folder /var/named/ telah didelet sebelumnya, setelah paket paket yang dibutuhkan tadi di instal lagi, maka /var/named/ akan ada lagi seperti yang dibutuhkan oleh sebuah server DNS , begitu juga dengan file named.conf yang berada di folder /etc
