CentOS6.4部署DNS服务器的记录

Linux就该这么学

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

客户端查询验证:

[root@racnode1 BACKUP-1]# nslookup

Address:        193.168.120.91#53

> abcdefgh.bcdgptv.com
Server:         193.168.120.91

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

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
