3. Modify the main configuration file

vim /etc/named.conf
options {
        listen-on port 53 { any; };      			#监听本机或者any
#        listen-on-v6 port 53 { ::1; };   			
        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";        
        recursing-file  "/var/named/data/named.recursing";
        secroots-file   "/var/named/data/named.secroots";
        allow-query     { any; };        			#允许所有主机解析

4. Modify the zone configuration file

vim /etc/named.rfc1912.zones
view “lan” { #define intranet view, view represents container segmentation
match-clients {192.168.132.0/24; };
#match intranet network segment zone “zhangsan.com” IN { #Set the zone to be parsed
type master;
file “zhangsan.com.zone.lan”; #Data configuration file

};
zone “.” IN {
#The root zone configuration can be cut from the main configuration file, dd+p type hint; #hint is the root zone type
file “named.ca”;
};
};

view “wan” {#define external network view
match-clients {any; };
#Match any address except the intranet network segment zone “zhangsan.com” IN { type master; file “zhangsan.com.zone.wan” ; }; };

#Note: Once the view is enabled, all zones must be under the view, so the default zone for the self-check of the system should also be placed under the view or deleted

5. Modify the regional data configuration file

cd /var/named
cp -p named.localhost zhangsan.com.zone.lan
cp -p named.localhost zhangsan.com.zone.wan

vim zhangsan.com.zone.lan
