在debian/ubuntu上搭建自己的DNS

这篇文章的目的就是简单的通过Bind9在自己的服务器（VPS）上架设自己的DNS服务器，这里选取的系统是debian或者ubuntu。

安装bind9

apt-get install bind9

配置和备份现有的bind9的设置

cp /etc/bind/named.conf.options /etc/bind/named.conf.options.bak

编辑 /etc/bind/named.conf.options 用下面的代码替换：

options {

direc”不可描述”y “/var/cache/bind”;

auth-nxdomain no;

listen-on-v6 { any; };

statistics-file “/var/cache/bind/named.stats”;

rrset-order {order cyclic;};

allow-transfer { 127.0.0.1; };

};

logging {

channel b_query {

file “/var/log/bind9/query.log” versions 2 size 1m;

print-time yes;

severity info;

};

category queries { b_query; };

};

为Bind9创建日志目录.

mkdir /var/log/bind9

chown bind:bind /var/log/bind9

编辑 /etc/bind/named.conf 配置你的域. 加上下面的:

zone “your-domain-name.com” {

type master;

file “/etc/bind/zones/your-domain-name.com.db”;

};

创建你的域

/etc/bind/zones/your-domain-name.com.db.

按照下面的模板插入你的DNS记录:

$TTL 86400

@ IN SOA ns1.your-domain-name.com. root.your-domain-name.com. (

2014100801 ; Serial

43200 ; Refresh

3600 ; Retry

1209600 ; Expire

180 ) ; Minimum TTL

; Nameservers

IN NS ns1.your-domain-name.com.

IN NS ns2.your-domain-name.com.

IN NS ns3.your-domain-name.com.

; Root site

IN A 123.456.78.90

; Hostname records

* IN A 123.456.78.90

sub1 IN A 123.456.78.91

sub2 IN A 123.456.78.92

; Aliases

www IN CNAME your-domain-name.com.

webmail IN CNAME ghs.google.com.

; MX records

@ IN MX 1 aspmx.l.google.com.

@ IN MX 3 alt1.aspmx.l.google.com.

@ IN MX 3 alt2.aspmx.l.google.com.

@ IN MX 5 aspmx5.googlemail.com.

; SPF records

@ IN TXT “v=spf1 ip4:199.195.140.194 include:_spf.google.com ~all”

Restart Bind9:

/etc/init.d/bind9 restart
