1、主DNS：
[root@dns ~]##apt  install -y bind9 bind9-utils
[root@dns ~]#cd /etc/bind
[root@dns bind]#vim named.conf.options
//  dnssec-validation auto;
[root@dns bind]#vim named.conf.default-zones 
zone "wang.org" {
    type master;
    file "/etc/bind/wang.org.local";
};
[root@dns bind]#vim wang.org.local
$TTL    604800
@   IN  SOA admin admin.wang.org. (
                  2     ; Serial
             604800     ; Refresh
              86400     ; Retry
            2419200     ; Expire
             604800 )   ; Negative Cache TTL
;
@   IN  NS  admin

[root@dns bind]#systemctl restart bind9.service
2、从DNS：
[root@dns-slave ~]#apt  install -y bind9 bind9-utils
[root@dns-slave ~]#cd /etc/bind

[root@dns-slave bind]#vim named.conf.options
//  dnssec-validation auto;
[root@dns-slave bind]#vim named.conf.default-zones
zone "wang.org" {
    type slave;
    file "/var/cache/bind/wang.org.local";      #注意此处路径，如果写/etc/bind/slaves 是没有权限的，无法同步.
    masters { 10.0.0.102; };
};
[root@dns-slave bind]#systemctl restart bind9.service
