ip:192.168.64.130 dns服务器

ip:192.168.64.128 客户端

 

第一步、安装bind-9.6.2

安装过程由脚本完成，脚本内容如下

 

#!/bin/bash
rm -rf /etc/yum.repos.d/*.repo
wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo -O /etc/yum.repos.d/CentOS-Base.repo
yum -y install openssl-devel
cd /usr/local/src
wget http://ftp.isc.org/isc/bind9/9.6.2-P2/bind-9.6.2-P2.tar.gz
tar -zxvf bind-9.6.2-P2.tar.gz
cd bind-9.6.2-P2
./configure --enable-largefile --enable-threads --prefix=/usr/local/named
make
make install
cd /usr/local/named/etc
/usr/local/named/sbin/rndc-confgen > /usr/local/named/etc/rndc.conf
tail -n10 rndc.conf |head -n9 |sed -e s/#\//g > named.conf
mkdir -p /usr/local/named/data
cd /usr/local/named/
wget ftp://ftp.rs.internic.net/domain/named.root
exit 1

第二步、修改配置文件

named.conf、rndc.conf这两个配置文件位置为：/usr/local/named/etc

域名相关的配置文件位置为：/usr/local/named

2-1、修改named.conf

修改后内容如下：

options {
        directory "/usr/local/named";
        pid-file "named.pid";
        listen-on port 53 {any;};
        allow-query {any;};
        dump-file "/usr/local/named/data/cache_dump.db";
        statistics-file "/usr/local/named/data/named_stats.txt";

};

key "rndc-key" {
        algorithm hmac-md5;
        secret "jhdbq+u4cE6KJdrJ6m6yAA==";
};

controls {
        inet 127.0.0.1 port 953
                 allow { 127.0.0.1; } keys { "rndc-key"; };
};

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

zone "localhost" IN {
         type master;
         file "localhost.zone";
         allow-update { none; };
};

zone "0.0.127.in-addr.arpa" IN {
         type master;
         file "localhost.rev";
          allow-update { none; };
};

zone "3gwlan.com" IN {
         type master;
         file "3gwlan.com.zone";
          allow-update { none; };
};

zone "64.168.192.in-addr.arpa" IN {
        type master;
        file "192.168.64.zone";
         allow-update { none; };
};

2-2、生成域名的配置文件

cd /usr/local/named

vim localhost.zone

 

$TTL 3600
@    IN SOA @    root (
                  20100923       ;serial (d. adams)
                  3H             ;refresh
                  15M            ;retry
                  1W             ;expiry
                  3600)          ;minimum
     IN NS   @
     IN A    127.0.0.1

 

vim localhost.rev

$TTL 3600
@   IN SOA   localhost.   root.localhost. (
             20100923      ; serial
             3600          ; refresh every hour
             900           ; retry every 15 minutes
             3600000       ; expire 1000 hours
             3600)         ; minimun 1 hour
     IN NS localhost.
1              IN PTR localhost.

 

vim 3gwlan.com.zone

@               IN SOA dns.3gwlan.com. root.3gwlan.com. (
                                        420000          ; serial (d. adams)
                                        3H              ; refresh
                                        15M             ; retry
                                        1W              ; expiry
                                        1D )            ; minimum
                IN NS           dns.3gwlan.com.
dns                 IN     A           192.168.64.131
www                 IN     A           192.168.64.128
3gwlan.com.         IN MX      5     mail.3gwlan.com.
bbs                 IN      CNAME      www
mail                IN   A             192.168.64.130

 

vim 192.168.64.zone

$TTL    86400
@               IN SOA dns.3gwlan.com. root.3gwlan.com. (
                                        1997022700      ; serial (d. adams)
                                        28800           ; refresh
                                        14400           ; retry
                                        3600000         ; expiry
                                        86400)         ; minimum
                IN NS                   dns.3gwlan.com.
130            IN PTR                         dns.3gwlan.com.
128            IN PTR                         www.3gwlan.com.
130            IN PTR                         mail.3gwlan.com.

 

第三步、测试

启动bind

 

/usr/local/named/sbin/named -gc /usr/local/named/etc/named.conf &

成功的界面为

 

在客户端进行测试

首先修改客户端的DNS

[root@lvs ~]# cat /etc/resolv.conf

 

; generated by /sbin/dhclient-script
search localdomain
nameserver 192.168.64.130

 

host 方式

 

正向查询

host www.3gwlan.com

 

www.3gwlan.com has address 192.168.64.128

反向查询

host 192.168.64.128

 

128.64.168.192.in-addr.arpa domain name pointer www.3gwlan.com.

 

查询NS

host -t NS 3gwlan.com

 

3gwlan.com name server dns.3gwlan.com.

 

查询SOA

host -t SOA 3gwlan.com

 

3gwlan.com has SOA record dns.3gwlan.com. root.3gwlan.com. 420000 10800 900 604800 86400

 

查询MX

host -t MX 3gwlan.com

 

3gwlan.com mail is handled by 5 mail.3gwlan.com.

 

nslookup 方式

 

正向查询

#nslookup

>www.3gwlan.com

Server:               192.168.64.130
Address: 192.168.64.130#53

Name:      www.3gwlan.com
Address: 192.168.64.128

反向查询

Server:               192.168.64.130
Address: 192.168.64.130#53

128.64.168.192.in-addr.arpa name = www.3gwlan.com.

 

别名查询
