二、生成配置named.conf
127.0.0.1 改成any
localhost 改成any
[root@node2 etc]# cp -p named.caching-nameserver.conf named.conf
[root@node2 etc]# pwd
/var/named/chroot/etc
[root@node2 etc]# vi named.conf
//
// named.caching-nameserver.conf
//
// Provided by Red Hat caching-nameserver package to configure the
// ISC BIND named(8) DNS server as a caching only nameserver
// (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//
// DO NOT EDIT THIS FILE - use system-config-bind or an editor
// to create named.conf - edits to this file will be lost on
// caching-nameserver package upgrade.
//

// Those options should be used carefully because they disable port
// randomization
// query-source port 53;

allow-query { any; };
allow-query-cache { any; };
};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
view localhost_resolver {
match-clients { any; };
match-destinations { any; };
recursion yes;
include "/etc/named.rfc1912.zones";
};

三、建立域
[root@node2 etc]# vi /var/named/chroot/etc/named.rfc1912.zones
zone "10.168.192.in-addr.arpa" IN {
type master;
file "10.168.192.in-addr.arpa";

};

配置正向解析資料檔案
[root@node2 named]# vi localdomain.zone

scan-cluster IN A 192.168.10.20

四、節點一配置
[root@node2 named]# vi /etc/resolv.conf
search localdomain
nameserver 192.168.10.11

[root@node2 named]# nslookup 192.168.10.22
Server: 192.168.10.11
Address: 192.168.10.11#53

22.10.168.192.in-addr.arpa name = scan-cluster.localdomin.10.168.192.in-addr.arpa.

[root@node2 named]# nslookup scan-cluster
Server: 192.168.10.11
Address: 192.168.10.11#53

Name: scan-cluster.localdomain
Address: 192.168.10.21
Name: scan-cluster.localdomain
Address: 192.168.10.22
Name: scan-cluster.localdomain
Address: 192.168.10.20

[root@node2 named]#
