1配置/etc/named.conf
options {
listen-on port 53 { 127.0.0.1; any;};
listen-on-v6 port 53 { ::1; };
directory “/var/named”;
dump-file “/var/named/data/cache_dump.db”;
statistics-file “/var/named/data/named_stats.txt”;
memstatistics-file “/var/named/data/named_mem_stats.txt”;

allow-query { localhost; any;};
acl “liantong” {192.168.122.0/24;};
acl “dianxin” {172.16.8.0/16;};
view inside{
match-clients{“liantong”;};
recursion yes;
zone “lfl.com” IN {
type master;
file “named.lfl”;
};

zone “122.168.192.in-addr.arpa” IN {
type master;
file “named.fx122”;
};
};

view outside{
match-clients{“dianxin”;};
recursion yes;
zone “lfl.com” IN {
type master;
file “named.lfl.172”;
};

zone “8.16.172.in-addr.arpa” IN {
type master;
file “named.fx122.172”;
};

};

2.复制
[root@kvm122102 named]# cp named.lfl named.lfl.172
[root@kvm122102 named]# cp named.fx122 named.fx122.172
