由 dawei 在这篇文章中我们来了解一下“如何用CentOS搭建自己的DNS服务器?”，一些朋友可能会遇到这方面的问题，对此在下文小编向大家来讲解，内容详细，易于理解，希望大家阅读完这篇能有收获哦，有需要的朋友就往下看吧!
系统环境：CENTOS6.4
1、安装软件：
yum install bind -y
2、配置，编辑完成以后的主配置文件内容如下：
[root@centos64 yum.repos.d]# 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 { 193.168.120.91; };
//listen-on-v6 port 53 { ::1; }; #此处须注释掉，否则在IPV4的网络环境下，添加反向解析以后，DNS服务不能启动
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 no; #此处将yes改为no,否则转发解析互联网的域名失败
dnssec-validation no; #此处将yes改为no,否则转发解析互联网的域名失败
/* 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";
zone "bcdgptv.com" IN {
type master;
file "named.bcdgptv.com";
};
zone "120.168.193.in-addr.arpa" IN {
type master;
file "named.193.168.120";
};
正向和反向的DNS解析文件如下，注意，须从左至右，左边不能留有空格，顶着左边书写，否则服务不能启动
[root@centos64 named]# pwd
/var/named
[root@centos64 named]# ls
data dynamic named.193.168.120 named.bcdgptv.com named.ca named.empty named.localhost named.loopback slaves
[root@centos64 named]# cat named.bcdgptv.com
$TTL 3H
@ IN SOA centos64.bcdgptv.com. admin@bcdgptv.com(
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
@ IN NS centos64.bcdgptv.com.
centos64 IN A 193.168.120.91

cos64 IN A 193.168.120.69
abcdefgh IN CNAME centos64
racnode1 IN A 193.168.120.71
[root@centos64 named]# cat named.193.168.120
$TTL 3H
@ IN SOA centos64.bcdgptv.com. admin@bcdgptv.com (
0 ; serial
1D ; refresh

1W ; expire
3H ) ; minimum
@ IN NS centos64.bcdgptv.com.
@ IN MX 10 cos64.bcdgptv.com
91 IN PTR centos64
69 IN PTR cos64
71 IN PTR racnode1
客户端查询验证：
[root@racnode1 BACKUP-1]# nslookup
> cos64.bcdgptv.com
Server: 193.168.120.91
Address: 193.168.120.91#53
Name: cos64.bcdgptv.com
Address: 193.168.120.69
> abcdefgh.bcdgptv.com
Server: 193.168.120.91
Address: 193.168.120.91#53
abcdefgh.bcdgptv.com canonical name = centos64.bcdgptv.com.
Name: centos64.bcdgptv.com
Address: 193.168.120.91
> set type=mx
> bcdgptv.com
Server: 193.168.120.91
Address: 193.168.120.91#53
bcdgptv.com mail exchanger = 10 cos64.bcdgptv.com.
> www.sina.com.cn
Server: 193.168.120.91
Address: 193.168.120.91#53
Non-authoritative answer:
www.sina.com.cn canonical name = spool.grid.sinaedge.com.
Authoritative answers can be found from:
sinaedge.com
origin = ns1.sinaedge.com
mail addr = null.sinaedge.com
serial = 20100707
refresh = 10800
retry = 60
expire = 604800
minimum = 60
A记录，别名，MX记录等均能正常查询，互联网的查询也能正常转发，服务部署成功
