view 视图，逻辑的DNS服务器，不一样的请求有意返回不一样的值
目标：120段解析返回120段的IP，其他解析返回130段IP
1、安装bind
[root@localhost ~]# yum -y install bind
2、配置主配置文件
[root@localhost ~]# sed "/^\//d" /etc/named.conf
options {
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 { 192.168.0.0/16; };
recursion yes;
/* Path to ISC DLV key */
};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
include "/etc/named.rfc1912.zones";
3、配置区域数据文件
[root@localhost ~]# sed "/^\//d" /etc/named.rfc1912.zones
view net120 {
match-clients { 192.168.120.0/24; };
zone "." IN {
type hint;
file "named.ca";
};
zone "localhost.localdomain" IN {
type master;
file "named.localhost";
allow-update { none; };
};
zone "localhost" IN {
type master;
file "named.localhost";
allow-update { none; };
};
zone "1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa" IN {
type master;
file "named.loopback";
allow-update { none; };
};
zone "1.0.0.127.in-addr.arpa" IN {
type master;
file "named.loopback";
allow-update { none; };
};
zone "0.in-addr.arpa" IN {
type master;
file "named.empty";
allow-update { none; };
};
zone "kaiyuandiantang.com" IN {
type master;
file "kaiyuandiantang.com.net120";
};
};
view net130 {
match-clients { any; };
zone "kaiyuandiantang.com" IN {
type master;
file "kaiyuandiantang.com.net130";
};
};
[root@localhost ~]#
4、配置数据库文件
[root@localhost named]# cat kaiyuandiantang.com.net120
$TTL 600
@ IN SOA ns1.kaiyuandiantang.com. admin.kaiyuandiantang.com. (
2017090801
1H
5M
3D
12H
)
IN NS ns1
IN MX 10 mail
ns1 IN A 192.168.130.120
mail IN A 192.168.120.10
www IN A 192.168.120.20
[root@localhost named]#
[root@localhost named]# cat kaiyuandiantang.com.net130
$TTL 600
@ IN SOA ns1.kaiyuandiantang.com. admin.kaiyuandiantang.com. (
2017090801
1H
5M
3D
12H
)
IN NS ns1
IN MX 10 mail
ns1 IN A 192.168.130.120
mail IN A 192.168.130.10
www IN A 192.168.130.20
[root@localhost named]#
5、修改权限启动服务
[root@localhost named]# chown root:named kaiyuandiantang.com.net1*
[root@localhost named]# chmod 640 kaiyuandiantang.com.net1*
[root@localhost named]# named-checkconf
[root@localhost named]# named-checkzone kaiyuandiantang.com kaiyuandiantang.com.net120
zone kaiyuandiantang.com/IN: loaded serial 2017090801
OK
[root@localhost named]# named-checkzone kaiyuandiantang.com kaiyuandiantang.com.net130
zone kaiyuandiantang.com/IN: loaded serial 2017090801
OK
[root@localhost named]# service named start
Generating /etc/rndc.key: [ OK ]
Starting named: [ OK ]
[root@localhost named]# tail /var/log/messages
