Linux下DNS服务器搭建详解(8)

                IN      NS      ns2.a.org.
72              IN      PTR     ns1.a.org.
71              IN      PTR     ns2.a.org.
73              IN      PTR     www.a.org.
74              IN      PTR     ftp.a.org.
 
从DNS服务器配置
1.安装bind包
yum install bind
2.复制named.conf、localhost.zone和named.local到本地对应目录
scp 192.168.0.72:/etc/named.conf /etc/named.conf
scp 192.168.0.72:/var/bind/localhost.zone /var/bind/localhost.zone
scp 192.168.0.72:/var/bind/named.local /var/bind/named.local
3.修改主配置文件/etc/named.conf
options {
    directory "/var/named"；         
}；
        
zone “.” IN  {
type hint;                                    
file "named.ca";                           
};      
        
zone "localhost" IN {
type master;
file "localhost.zone";
};  
        
zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
};
 
zone "a.org." IN {                  
type slave;                           #声明从服务器
file "slaves/a.org.zone";             #同步文件保存路径
masters { 192.168.0.72; };            #主服务器ip
};                      
 
zone "168.192.in-addr.arpa"  IN {
type slave;
