Linux下DNS服务器搭建详解(6)

4.检测配置文件语法
named-checkconf 
named-checkzone “localhost” /var/named/localhost.zone
named-checkzone “0.0.127.in-addr.arpa” /var/named/named.local
5.开启服务并测试
service named start
dig -t A  域名      #测试正解
dig -x ip地址       #测试反解
 
主DNS服务器配置
1.修改主配置文件
vim /etc/name.conf
zone "a.org" IN {
type master;
file "a.org.zone";
};  
zone "0.168.192.in-addr.arpa" IN {
type master;
file "192.168.zone";
};  
2.生成解析文件
/var/named/a.org.zone
$TTL    1200
@               IN      SOA     ns1.a.org.      admin.a.org.    (
                                                        2011081601
                                                        1H
                                                        10M
                                                        7D                                                       
)
                 IN      NS      ns1.a.org.        #NS包括主从两台服务器
                 IN      NS      ns2.a.org.
