Ubuntu 12.04 Install DNS Server

安裝bind9

# sudo apt-get install bind9 bind9-host dnsutils bind9-doc

設定檔：
/etc/bind/named.conf.option
/etc/bind/named.conf
/etc/bind/named.conf.local

vi named.conf.opteam 注意結尾符號為分號，每一行敘述或一個括號後都要有。

這是可以讓當外部dns用時要設定的

query-source address * port 53;
forwarders {
168.95.1.1;
 };
allow-query { any; };
allow-transfer { none; };
auth-nxdomain no; # conform to RFC1035
 listen-on-v6 { any; };
};

如果只是要做private  ip dns時可以設定以下

acl lan {
127.0.0.1;
172.16.0.1/24;
};//設定Access Control List
options {
directory "/var/cache/bind";
allow-query { lan;}; //只讓lan內部的人query
};

 vi named.conf

Zone定義是dns伺服器管理的邏輯單位 ex.dns.tonyhack.com

 include "/etc/bind/named.conf.options";

include "/etc/bind/named.conf.local";

 include "/etc/bind/named.conf.default-zones"  

//增加使用者domain正解區域(Zone)
zone "tonyhack.com" { 
type master;
file "/etc/bind/db.tonyhack";
 };

//增加使用者domain反解區域(Zone)
zone "242.126.59.in-addr.arpa" { 
type master;
file "/etc/bind/db.tonyhack.rev";
 };

複製一份空的檔案來做自已zone以下是我的範例

cp db.empty db.tonyhack

$TTL 604800
@ IN SOA tonyhack.com. dns.tonyhack.com. (
1 ; Serial
604800 ; Refresh
86400 ; Retry
419200 ; Expire
604800 ) ; Negative Cache TTL
 ;
@ IN NS dns.tonyhack.com.
@ IN NS www.tonyhack.com.
dns.tonyhack.com. IN A 192.168.1.7
www.tonyhack.com. IN A 59.126.242.79

@ IN MX 10 ms1
@ IN MX 20 ms2
ms1 IN A 192.168.1.7
ms2 IN A 192.168.1.7

dns 10 IN A 192.168.1.7
www 10 IN A 192.168.1.7
web IN CNAME www

重啟bind9

/etc/init.d/bind9 restart

測試是否查詢的到，相關dns查詢指令nslookup、dig、whois
