DNS Server

設定DNS Server (固定IP)
1.申請DomainName
http://www.dynadot.com/ 國外
http://www.twnic.net/ 台灣

2.安裝套件 bind9

3.設定 /etc/bind/named.conf.local
zone "網域名稱" {
type master;
file "/etc/bind/zones/網域名稱";
};

4.新增DNS設定檔
#cd /etc/bind
#mkdir zones #cd zones
#vi 網域名稱
$TTL 86400
@ IN SOA abc.def.org. root (
2008092401 ;serial
604800 ;refresh
14400 ;retry
36800 ;expire
86400 ) ;negative cache TTL
@ IN NS ns1.abc.def.org.
@ IN NS ns2.abc.def.org.
@ IN A 123.123.123.123
@ IN MX 10 abc.def.org.
@ IN MX 20 mail
ns1 IN A 123.123.123.123
ns2 IN A 123.123.123.123
www IN A 123.123.123.123
ftp IN CNAME www
mail IN A 123.123.123.123


5.設定 vi /etc/resolv.conf
加入 nameserver 127.0.0.1

6.重新啟動
#/etc/init.d/bind9 restart


當DNS無法正常啟動時，利用tail 來除錯
debian:~# tail -100 /var/log/syslog
