zone "named.magedu.com" IN{
type master;
file "named.magedu.com.zone";
}
(2)编辑/var/named/named.magedu.com.zone
$TTL 3600

@ IN SOA named.magedu.com. mail.magedu.com.( 20170913 1H 10M 3D 1D )
@ IN NS ns1.magedu.com.
@ IN MX 10 mx1.magedu.com.
ns1.magedu.com. IN A 192.168.1.1
mx1.magedu.com. IN A 192.168.1.2
www.magedu.com. IN A 192.168.1.3
(3)检测 named -checkzone named.magedu.com.zone
(4)rndc reload

@ IN SOA named.magedu.com. mail.magedu.com.( 20170913 1H 10M 3D 1D ) @ IN NS ns1.magedu.com.
1 IN PTR ns1.magedu.com.
