多view的DNS服务器配置文件组织

1. 文件acl.cernet,内容为
acl “CERNET” {
  58.154.0.0/15;
  58.192.0.0/12;
  59.64.0.0/12;
  116.13.0.0/16;
…
};

2.  文件acl.chinanet,内容为
acl “CHINANET” {
58.30.0.0/15;
58.32.0.0/11;
58.66.192.0/18;
…
};

3. 文件/etc/named.common.conf,存放named.conf中每个view公共的东西,内容为
zone “.” IN { type hint; file “named.ca”; };
zone “localdomain” IN { type master; file “localdomain.zone”; allow-update { none; }; };
zone “localhost” IN { type master; file “localhost.zone”; allow-update { none; }; };
zone “0.0.127.in-addr.arpa” IN { type master; file “named.local”; allow-update { none; }; };
zone “0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa” IN { type master; file “named.ip6.local”; allow-update { none; }; };
zone “255.in-addr.arpa” IN { type master; file “named.broadcast”; allow-update { none; }; };
zone “0.in-addr.arpa” IN { type master; file “named.zero”; allow-update { none;}; };

zone “64.38.202.IN-ADDR.ARPA” in{type master; file “revs/named.202.38.64.rev”;};
…

4. 文件/etc/named.conf,主要内容为

…
include “/var/named/acl.cernet”;
include “/var/named/acl.chinanet”;
…
view “CERNET” {
match-clients { CERNET;};
include “/etc/named.common.conf”;
zone “ustc.edu.cn” in{type master; file “zones/cernet.named.ustc.edu.cn.zone”;};
};

view “CHINANET” {
match-clients { CHINANET;};
include “/etc/named.common.conf”;
zone “ustc.edu.cn” in { type master; file “zones/chinanet.named.ustc.edu.cn.zone”;};
};

view “Other” {
match-clients { any;};
include “/etc/named.common.conf”;
zone “ustc.edu.cn” in { type master; file “zones/other.named.ustc.edu.cn.zone”;};
};

5. 文件common.named.ustc.edu.cn.zone,存放所有view完全一样的东西,内容为
@      IN      SOA    ns.ustc.edu.cn. james.ustc.edu.cn. (
        812
        1200      ; refresh (20 min )
        300      ; retry (5 min)
        7200    ; expire (2 hour)
        600      ; minimum (10 min)
        )
        IN      NS      ns.ustc.edu.cn.
        IN      NS      mx.ustc.edu.cn.

; 重要服务器
ns              IN      A      202.38.64.1
mx              IN      A      202.38.64.56
…
msclub          CNAME  revproxy
job            CNAME  revproxy
www.job        CNAME  revproxy
…

6. 文件cernet.named.ustc.edu.cn.zone,存放CERNET view的信息
$INCLUDE common.named.ustc.edu.cn.zone
revproxy        IN      A      202.38.64.246
bbs            IN      A      202.38.64.3
…

7. 文件chinanet.named.ustc.edu.cn.zone,存放ChinaNET view的信息
$INCLUDE common.named.ustc.edu.cn.zone
revproxy        IN      A      218.22.21.25
bbs            IN      A      202.141.160.3
…

8. 文件othernet.named.ustc.edu.cn.zone,存放Other view的信息
$INCLUDE common.named.ustc.edu.cn.zone
revproxy        IN      A      218.104.71.173
bbs            IN      A      218.104.71.174
…

这样组织以后,每次修改数据,必须要修改common.named.ustc.edu.cn.zone中的序列号.
