BIND9 - Master / Slave DNS 基本設定備忘 named.conf 重點內容 Slave 主機向 Master 要求傳送 Zone File 的時機 Zone File 檔案結構 named.conf 重點內容 Master: vi /etc/named.conf acl "trusted" { 127.0.0.1; 192.168.1.0/24; }; options { allow-recursion { trusted; }; //避免變成 Open DNS allow-transfer { none; }; //預設禁止 Zone Transfer notify no; //預設不通知轄區 DNS Server }; zone "mydomain.com" in { type master; file "mydomain.com.zone"; allow-transfer { slave.ip.address; }; notify yes; }; zone "1.168.192.in-addr.arpa" in { type master; file "192.168.1.zone"; allow-transfer { slave.ip.address; }; notify yes; }; Slave: vi /etc/named.conf zone "mydomain.com" in { type slave; file "slave/mydomain.com.zone"; masters { master.ip.address; }; }; zone "1.168.192.in-addr.arpa" in { type slave; file "slave/192.168.1.zone"; masters { master.ip.address; }; }; Slave 主機向 Master 要求傳送 Zone File 的時機 master 主機上的 named 啟動、Reload 時, 發送 dns notify 信號通知 NS 主機 (除本身外) 比對 zone file serial, 且 master serial 大於 slave serial 時. slave 主機上的 named 啟動時, 發現 master serial 大於 slave serial, 或無 zone file 存在時. slave 主機每隔 refresh 時間, 向 master 查詢 zone file serial, 發現 master serial 大於 slave serial 時.
