在緩存名稱dns的基礎上添加正向和反向的dns解析

在/etc/named.conf中加入以一個新域 a.org.zone： Zone?“a.org” IN?{ Type?master; File?? “a.org.zone”; }; 然后要編輯創(chuàng)建a.org.zone Vim /var/named/a.org.zone $TTL 1200 @IN??????? SOA??????? ns1.a.org.?????? admin.a.org. ( 2011081801 1D 10M 7D 1D ) IN????? NS????????????????????? ns1.a.org. IN????? NS????????????????????? ns2.a.org. ns1.a.org.IN????? A????????????????????? 192.168.0.73 ns2.a.org.IN????? A????????????????????? 192.168.0.72 mail.a.org.IN????? A????????????????????? 192.168.0.74 www.a.org.IN????? A????????????????????? 192.168.0.73 bbs.a.org.IN????? CNAME?????????????????? www.a.org. ftp.a.org.IN??? ??A??????????????????????? 192.168.0.100 編輯保存之后要把a.org.zone的屬組改為named Chown:named?? /var/named/a.org.zone 查看文件屬性?ll /var/named/a.org.zone -rw-r--r-- 1 root named 834 Aug 17 21:39 /var/named/a.org.zone 改了配置文件之后我們 千萬要記住重新載入服務 Service?named?reload 或者 service?named?restart 然后要看下/etc/resolv.conf?把nameserver的ip確定 為127.0.0.1 如果重啟成功我們就可以測試一下了 Dig?-t?A?www.a.org顯示的結果如下： ; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5 <<>> -t A www.a.org ;; global options:?printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 7814 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2 ;; QUESTION SECTION: ;www.a.org.IN????
