高速缓存DNS配置

高速缓存DNS配置 一台交换机连一台主DNS，连高速缓存DNS，连一台客户机。 1三台机IP分别为192.168.1.2/24;192.168.1.3(DNS);192.168.1.4(缓) 2三台主机名分别为A、B、C 主DNS配制 3 vi /etc/named.conf Zone”ycit.com” IN { Type master; File”newname1.db” }; Zone”1.168.192.in-addr.arpa” IN { Type master; File”newname2.db” }; #注:newname1.db和2是区文件，自已起名新建 4 cd /var/named cp named.local newname1.db cp named.local newname2.db vi newname1.db $ TTL 86400 @ IN SOA B.ycit.com. lz-lz333.tom.com 2005101000 Serial IN ns B.ycit.com. B IN A 192.168.1.3 A IN A 192.168.1.2 Vi newname2.db $ TTL 86400 @ IN SOA B.ycit.com. lz-lz333.tom.com 2005101000 Serial IN ns B.ycit.com. 3 IN PTR B.ycit.com. 2 IN PTR A.ycit.com. 5 vi /etc/resolv.conf search ycit.com nameserver 192.168.1.3 6 service named restart 高速缓存DNS配制 1 vi /etc/named.conf directory “/var/named”; # allow-query { 192.168.1.0/24 }; Zone”ycit.com” IN { Type hint; File”newname1.db” }; Zone”1.168.192.in-addr.arpa” IN { Type hint; File”newname2.db” }; 5 vi /etc/resolv.conf search ycit.com nameserver 192.168.1.4 6 service named restart 客户机 5 vi /etc/resolv.conf search ycit.com nameserver 192.168.1.4 说明:1 客户机发出nslookup，192.168.1.2 2转高速缓存DNS解析，不能解析，转主DNS解析，解析成 功 3去除主DNS，作上面同样操作，高速缓存DNS能解析。
