求助,BIND9 无法解析配置好的资源记录

有大大熟悉 DNS 的看到还麻烦解决下疑惑,花了一天排查都不知道问题出在哪里

环境:

CentOS 7
防火墙关闭,selinux 关闭

YUM 安装以下包

bind-libs-9.9.4-61.el7.x86_64
bind-9.9.4-61.el7.x86_64
bind-utils-9.9.4-61.el7.x86_64

/etc/named.conf 配置,改了个监听 IP,删除 dnssec 相关的行,其它基本没有改动

options {
        listen-on port 53 { 192.168.4.95; };
        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; };
        recursion yes;
        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";

/etc/named.rfc1912.zones 配置,在最后添加以下,其它没动

zone "test" IN {
        type master;
        file "test.zone";
};

/var/named/test.zone 配置

$TTL 100
@       IN      SOA     ns1.main.ccom.  mail.main.ccom. (
                        2018062201
                        1H
                        5M
                        7D
                        100 )
        IN      NS      ns1
        IN      MX 10   mx1
ns1     IN      A       192.168.4.95
mx1     IN      A       192.168.4.96
test    IN      A       172.16.4.4
www     IN      A       192.168.4.11
ftp     IN      CNAME   www

测试

systemctl start named.service # 启动正常

已监听在 53 端口上

ss -tunlp | grep 53
udp  UNCONN  0   0    192.168.4.95:53   *:*   users:(("named",pid=1893,fd=512))
tcp   LISTEN     0   10  192.168.4.95:53   *:*     users:(("named",pid=1893,fd=21))

dig 测试,在本机和其它机器上测试结果相同

dig -t A ftp.main.ccom @192.168.4.95

返回结果
