Install and confgure DNS For RHEL/Centos/Fedora
Build DNS server which resolves domain name or IP address. Install bind and caching-nameserver for it. And it’s also neccessary to configure router so that TCP and UDP packets to 53 can pass through.
[root@ns ~]# yum -y install bind caching-nameserver
Installed: bind.i386 30:9.3.3-8.el5 caching-nameserver.i386 30:9.3.3-8.el5
Complete!
Configure BIND
Here is an example to configure BIND with named.conf.
This example is done with grobal IP address [172.16.0.80/29], Private IP address [192.168.0.0/24], Domain name [unixmen.net]. However, Please use your own IPs and domain name when you set config on your server. ( Actually, [172.16.0.80/29] is for private IP address, though. )
===============================================================
[root@unixmen.net ~]# vi /etc/named.conf
options {
directory “/var/named”;
/*
* 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;
allow-query { localhost; 192.168.0.0/24; };
// query range
allow-transfer { localhost; 192.168.0.0/24; };
// transfer range
allow-recursion { localhost; 192.168.0.0/24; };
// recursion range
};
controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
// here is the section for internal informations
view “internal” {
match-clients {
localhost;
192.168.0.0/24;
};

type hint;

};

type master;
file “80.0.16.172.db”;
allow-update { none; };
};
};
include “/etc/rndc.key”;
// *note: For How to write for reverse resolving, Write network address reversely like below.
the case for 192.168.0.0/24
network address ⇒ 192.168.0.0
range of network ⇒ 192.168.0.0 – 192.168.0.255
how to write ⇒ 0.168.192.in-addr.arpa
case of 172.16.0.80/29
network address ⇒ 172.16.0.80
range of network ⇒ 172.16.0.80 – 172.16.0.87
how to write ⇒ 80.0.16.172.in-addr.arpa
