动态 DNS，基本配置不起作用

Question

我正在尝试实现 DDns，其中 DHCP 守护进程代替我更新 dns 记录。据我所知，它应该可以工作。但事实并非如此。如果有人指出我的错误配置，我将不胜感激。

文件权限正确，两个服务器上的密钥相同。使用的是 Centos 7。NATed KVM 内部一切正常。

DNS：192.168.1.10

DHCP：192.168.1.100

子网：192.168.1.0/24

和我的配置：

命名的.conf：

 acl good_guys {
        192.168.1.0/24;
};


include "/etc/rndc.key";
controls {
         inet 127.0.0.1 allow {192.168.1.10; localhost;} keys {"rndc-key";}; 
};



options {
        listen-on port 53 { 127.0.0.1; 192.168.1.10; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";

        memstatistics-file "/var/named/data/named_mem_stats.txt";
        allow-query     { localhost; good_guys; };
        allow-query-cache { localhost; any; };

        recursion no;

        dnssec-enable no;
        dnssec-validation no;

        bindkeys-file "/etc/named.iscdlv.key";

        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";
};

zone "matrix.lab" IN {
        type master;
        file "matrix.lab.zone";
        allow-update { key "rndc-key"; };
        notify yes;
};
