(1) [root@yutianedu ~]# vim /etc/ named.conf
options {
       listen-on port 53 { any; }; # Set listening
        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     { any; };           # 允许查询
recursion yes;
        dnssec-enable yes;
        dnssec-validation yes;
        dnssec-lookaside auto;

        /* Path to ISC DLV key */
        bindkeys-file "/etc/named.iscdlv.key";

        managed-keys-directory "/var/named/dynamic";

        pid-file "/run/named/named.pid";
        session-keyfile "/run/named/session.key";
};

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};

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

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

（2）# vim /etc/named.rfc1912.zones
# 在该文件的最末尾加入以下内容
zone "jison.com" IN {
        type master;
        file "jison.zone";
        allow-update { none; };
};
7.配zones
cd /var/named
cp -p named.localhost jison.zone
vi jison.zone
# cp –p /var/named/named.localhost /var/named/jison.zone
# vim /var/named/google.zone
