编辑区域数据库文件
[root@localhost ~]# vim /var/named/magedu.com.zone1

编辑dns配置文件
[root@localhost /var/named]# vim /etc/named.conf
acl beijingnet {192.168.119.129;};
acl tianjin {192.168.119.0/24;10.0.0.0/8;};
acl shanghainet {192.168.119.0/24;};
acl other {any;};
把/etc/named.conf文件中的
zone “.” IN {
type hint;
file “named.ca”;
};
迁移到/etc/named.rfc1912.zones中
[root@localhost ~]# vim /etc/named.rfc1912.zones
zone “.” IN {
type hint;
file “named.ca”;
};
acl 定义了不同的用户访问的不同的数据库
有了view就需要把区域信息放入到view中
配置文件
[root@localhost /var/named]# vim /etc/named.conf
acl beijingnet {192.168.119.129;};
acl tianjin {192.168.119.0/24;10.0.0.0/8;};
acl shanghainet {192.168.119.0/24;};
acl other {any;};
options {
// listen-on port 53 { 127.0.0.1; };
// allow-query { localhost; };
// allow-transfer {192.168.119.136;};
view beijingview{
match-clients {beijingnet;};
zone “magedu.com” IN {
type master;
file “magedu.com.zone1“;
};
include “/etc/named.rfc1912.zones”;
};
include “/etc/named.root.key”;
view shanghaiview{
match-clients {shanghainet;};
zone “magedu.com” IN {
type master;
file “magedu.com.zone2“;
};
include “/etc/named.rfc1912.zones”;
};
view otherview{
zone “magedu.com” IN {
type master;
file “magedu.com.zone2“;
};
include “/etc/named.rfc1912.zones”;
};
