配置NDS 域名解析
直接添加一下内容:

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

zone "11.168.192.in-addr.arpa" IN {
type master;
file "11.168.192.local";
allow-update{none;};
};

正向解析 配置

[root@mail ~]# cat /var/named/wangxiaojing.com.zone 
$TTL 1D @ IN SOA @ dns.wangxiaojing.com. (
0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS @ A 127.0.0.1 AAAA ::1 IN NS dns.wangxiaojing.com. IN MX 10 dns.wangxiaojing.com. dns IN A 172.16.2.18 mail IN CNAME dns pop3 IN CNAME dns smtp IN CNAME dns imap4 IN CNAME dns

配置反向解析

[root@mail ~]# cat /var/named/11.168.192.local 
$TTL 1D
@    IN SOA    @ dns.wangxiaojing.com. (
0    ; serial
1D    ; refresh
1H    ; retry
1W    ; expire
3H )    ; minimum
NS    @
A    127.0.0.1
AAAA    ::1
IN NS dns.wangxiaojing.com.
18 IN PTR dns.wangxiaojing.com.

 

设置开机自启动

chkconfig named on
service named start

 

配置 /etc/resolv.conf
(重启之后配置会失效)

cat /etc/resolv.conf 

search wangxiaojing.com nameserver
172.16.2.18 nameserver 8.8.8.8 nameserver 8.8.4.4

 

检测 NDS 解析:

[root@mail ~]# nslookup -qt=mx mail.wangxiaojing.com
*** Invalid option: qt=mx Server: 172.16.2.18 Address: 172.16.2.18#53 mail.wangxiaojing.com canonical name = dns.wangxiaojing.com. Name: dns.wangxiaojing.com Address: 172.16.2.18
