安装软件包
[[email protected] ~]# yum -y install bind bind-chroot caching-nameserver

修改配置文件，将localhost和127.0.0.1修改为any。
[[email protected] ~]# cp /etc/named.conf /etc/named.conf.bak
[[email protected] ~]# vim /etc/named.conf
[[email protected] ~]# cat /etc/named.conf
//
// named.conf
//
// Provided by Red Hat bind 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.
//

options {
        listen-on port 53 { any; };
        listen-on-v6 port 53 { ::1; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        allow-query     { any; };
        recursion yes;

        dnssec-enable yes;
        dnssec-validation yes;
        dnssec-lookaside auto;

        /* Path to ISC DLV key */
        bindkeys-file "/etc/named.iscdlv.key";

        managed-keys-directory "/var/named/dynamic";
};

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};

zone "." IN {
        type hint;
        file "named.ca";
};

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

配置正反向解析zone文件解析scanip,在named.rfc1912.zones末尾加上
zone "rac-scan" IN {
      type master;
      file "rac-scan.zone";
      allow-update { none; };
};

zone "10.168.192.in-addr.arpa." IN {
        type master;
        file "10.168.192.in-addr.arpa";
        allow-update { none; };
};

[[email protected] ~]# cp /etc/named.rfc1912.zones /etc/named.rfc1912.zones.bak
[[email protected] ~]# vim /etc/named.rfc1912.zones
[[email protected] ~]# tail -11 /etc/named.rfc1912.zones
zone "rac-scan" IN {
      type master;
      file "rac-scan.zone";
      allow-update { none; };
};

zone "10.168.192.in-addr.arpa." IN {
        type master;
        file "10.168.192.in-addr.arpa";
        allow-update { none; };
};
将其余内容注释掉。

配置正，反向解析数据库文件，在反向解析文件中加入150 IN PTR rac-scan.
[[email protected] ~]# cd /var/named/
[[email protected] named]# cp -p named.localhost 10.168.192.in-addr.arpa
[[email protected] named]# vim 10.168.192.in-addr.arpa
[[email protected] named]# tail -1 10.168.192.in-addr.arpa
130 IN PTR rac-scan.

在正向解析文件中加入rac-scan IN A 192.168.10.130
[[email protected] ~]# cd /var/named/
[[email protected] named]# cp -p named.localhost rac-scan.zone
[[email protected] named]# vim rac-scan.zone
[[email protected] named]# cat rac-scan.zone
$TTL    86400
@               IN SOA  localhost root (
                                        42              ; serial (d. adams)
                                        3H              ; refresh
                                        15M             ; retry
                                        1W              ; expiry
                                        1D )            ; minimum
                IN NS           localhost
localhost       IN A            127.0.0.1
rac-scan        IN A            192.168.10.130

将以上的两个文件及named.ca拷贝到/var/named/chroot/var/named/目录下
[[email protected] named]# cp -a rac-scan.zone chroot/var/named/
[[email protected] named]# cp -a 10.168.192.in-addr.arpa chroot/var/named/
[[email protected] named]# cp -a named.ca chroot/var/named/
[[email protected] named]# ll /var/named/chroot/var/named/
total 12
-rw-r----- 1 root named  183 Jul 11 17:07 10.168.192.in-addr.arpa
-rw-r----- 1 root named 2075 Apr 23  2014 named.ca
-rw-r--r-- 1 root named  524 Jul 11 17:07 rac-scan.zone

检查文件是否配置正确
[[email protected] named]# named-checkzone rac-scan rac-scan.zone
zone rac-scan/IN: loaded serial 42
OK

[[email protected] named]# named-checkzone rac-scan 10.168.192.in-addr.arpa
zone rac-scan/IN: loaded serial 0
OK

重启DNS服务
[[email protected] named]# /etc/init.d/named restart
Stopping named: .                                          [  OK  ]
Starting named:                                            [  OK  ]

[[email protected] ~]# cat /etc/resolv.conf

[[email protected] ~]# cat /etc/resolv.conf
