======DNS 的 VIEW

DNS视图用于：服务器既向内部提供解析，又向外部提供解析时使用.

首先在服务器上要有两块网卡，一个负责解析内部的请求，例如为：192.168.1.1；另一个负责外部的请求：192.168.2.1；

搭建DNS环境，在主配置文件里添加：grep -v '^$' /var/named/chroot/etc/named.conf | grep -v '^#' | grep -v '//'：

options {    listen-on port 53 { 127.0.0.1; 192.168.1.1; 192.168.2.1; };            //一定要将监听的两个地址都写进去；    directory   "/var/named";    dump-file   "/var/named/data/cache_dump.db";        statistics-file "/var/named/data/named_stats.txt";        memstatistics-file "/var/named/data/named_mem_stats.txt";    allow-query     { any; };    allow-query-cache { any; };};logging {        channel default_debug {                file "data/named.run";                severity dynamic;        };};view xiaozi-neibu {    match-clients      { 192.168.1.0/24; };            //只负责内部主机的解析请求；    match-destinations { 192.168.1.0/24; };    recursion yes;    include "/etc/xiaozi.neibu.com";};view xiaozi-waibu {    match-clients      { any; };    match-destinations { any; };    recursion yes;    include "/etc/xiaozi.waibu.com";};

xiaozi.neibu.com：

zone "xiaozi.com" IN {        type master;        file "xiaozi.neibu.zone";};

xiaozi.waibu.com：

zone "xiaozi.com" IN {        type master;        file "xiaozi.waibu.zone";};

xiaozi.neibu.zone：

$TTL    86400@               IN SOA  xiaozi.com.       root.xiaozi.com. (                                        42              ; serial (d. adams)                                        3H              ; refresh                                        15M             ; retry                                        1W              ; expiry                                        1D )            ; minimum                IN NS           www.xiaozi.com.www             IN A            192.168.1.1

xiaozi.waibu.zone：

$TTL    86400@               IN SOA  xiaozi.com.       root.xiaozi.com. (                                        42              ; serial (d. adams)                                        3H              ; refresh                                        15M             ; retry                                        1W              ; expiry                                        1D )            ; minimum                IN NS           www.xiaozi.com.www             IN A            192.168.2.1

大家一定要注意iptables 和 selinux 的设置

现在就可以启动DNS服务了

外部解析到的 的ip为192.168.2.1；内部主机解析到的ip为192.168.1.1； 就说明成功了.

^_^ 祝大家好运！ 如果xiaozi写的哪里有不对的地方，还请各位多多指点，谢谢
