主DNS服务器配置

主DNS服务器使用Redhat7.5，域名为juzldream.fun,且搭配的IP网段为192.168.5.0/24这一段，因此主要的正解网域为juzldream.fun，而反解的网域则为192.168.5.0/24。

配置/etc/named/named.conf options选项配置

options {
        directory       "/var/named";
        allow-recursion {192.168.5.136;};
        notify yes;         #启动通知功能
};

zone "." IN {
        type hint;
        file "named.ca";
};

zone "localhost" IN {
        type master;
        file "named.localhost";
        allow-transfer {none;};  #不允许增量传送
};

zone "0.0.127.in-addr.arpa" IN {
        type master;
        file "named.loopback";
        allow-transfer {none;};
};

zone "juzldream.fun" IN {
        type master;
        file "juzldream.fun";
        allow-transfer {192.168.5.128;};     #允许192.168.5.128从服务器传送
}; 

zone "5.168.192.in-addr.arpa" IN {
    type master;
    file "juzldream.back";
    allow-transfer {192.168.5.128;};
