轉(zhuǎn)發(fā)服務(wù)器------準(zhǔn)備3個(gè)虛擬機(jī)裙犹；
將centos6設(shè)置為轉(zhuǎn)發(fā)服務(wù)器尽狠；
將centos7設(shè)置為DNS服務(wù)器衔憨；
將centos5設(shè)置為客戶端；
1袄膏、更改/etc/named.conf文件（centos6）;
在option選項(xiàng)里添加践图；
forward only;
forwarders { 192.168.226.133;};
需要更改選項(xiàng)，將yes改為no;
dnssec-enable no;
dnssec-validation no;
2沉馆、更改/etc/named.rfc1912.zones文件（centos6）;
zone "magedu.com"{
type forward;
forward only;
forwarders {192.168.226.133;};
};
轉(zhuǎn)發(fā)服務(wù)器
需要注意码党，centos6的DNS數(shù)據(jù)庫文件，/etc/named.conf,/etc/named.rfc1912.zones;
有無需要注釋掉的選項(xiàng)斥黑；
ACL
1揖盘、準(zhǔn)備數(shù)據(jù)庫文件；
#cp -p /var/named/magedu.com.zone /var/named/magedu.com.zone.bj
#cp -p /var/named/magedu.com.zone /var/named/magedu.com.zone.zz
編寫數(shù)據(jù)庫文件锌奴；
$TTL 1D
@ IN SOA dns1.magedu.com. dnsadmin.magedu.com. (
202 ; serial
10M ; refresh

#都訪問magedu.com域鹿蜀；
2箕慧、編輯/etc/named.conf文件；
頂行添加耻姥；表示所訪問的客戶端地址销钝；
acl beijing {192.168.226.134;};
acl zhengzhou {192.168.226.135;};
acl other {any;};
指明客戶端訪問的數(shù)據(jù)庫路徑的配置文件；
view beijingview {
match-clients {beijing;};
include "/etc/beijing.view.zones";
};
view zhengzhouview {
match-clients {zhengzhou;};
include "/etc/zhengzhou.view.zones";
};
view otherview {
match-clients{other;};
include "/etc/named.rfc1912.zones";
};
將指明dns根路徑的文件剪切琐簇，刪除 include "/etc/named.rfc1912.zones“行蒸健；
3、將剪切的dns根路徑文件復(fù)制到/etc/named.rfc1912.zones配置文件里婉商；
zone "." IN {
type hint;
file "named.ca";
};
4似忧、編輯beijing、zhengzhou的數(shù)據(jù)庫路徑配置文件丈秩；
/etc/beijing.view.zones
/etc/zhengzhou.view.zones
#vim /etc/beijing.view.zones
zone "magedu.com" IN {
type master;
flie "magedu.com.zone.bj";
};
#vim /etc/zhengzhou.view.zones
zone "magedu.com" IN {
type master;
file "magedu.com.zone.zz";
};
5盯捌、使用centos6、centos5進(jìn)行訪問蘑秽；
