利用DNS视图实现不同地区用户使用相同域名访问不同服务器

dns实现视图：上海和西安的用户使用相同域名访问不同的web服务器

第一步：注释一些代码->[之前手动配置的正向和反向解析的代码]

[root@server ~]# vim /etc/named.conf
/*
zone "." IN {
        type hint;
        file "named.ca";
};
​
zone "openlab.com" IN {
        type master;
        allow-transfer {192.168.118.130};
        file "openlab.com.zone";
};
​
​
zone "118.168.192.in-addr.arpa" IN {  
        type master;
        allow-transfer {192.168.118.130};
        file "192.168.118.arpa";     
};
*/
# include "/etc/named.rfc1912.zones";
​

第二步：写视图

[root@server ~]# vim /etc/named.conf
acl client_sh { 192.168.118.129; };
acl client_xa { 192.168.118.1; };
view "shanghai" {
  match-clients {client_sh;};
  zone "." IN {
    type hint;
    file "named.ca";
  };
  zone "openlab.com" IN {
    type master;
    file "openlab.shanghai";
  };
  zone "118.168.192.in-addr.arpa" IN {
    type master;
    file "118.168.192.shanghai";
  };
};
view "xian" {
  match-clients {client_xa;};
  zone "." IN {
    type hint;
    file "named.ca";
  };
  zone "openlab.com" IN {
    type master;
    file "openlab.xian";
  };
  zone "118.168.192.in-addr.arpa" IN {
    type master;
    file "118.168.192.xian";
  };
};
​

第三步：准备文件，进行修改

[root@server named]# cp openlab.com.zone openlab.xian
[root@server named]# cp openlab.com.zone openlab.shanghai
[root@server named]# cp 192.168.118.arpa 118.168.192.xian
[root@server named]# cp 192.168.118.arpa 118.168.192.shanghai
​
拷贝文件后进入改www.openlab.com.这一行的ip【正反都改】

第四步：检测重启

[root@server named]# named-checkconf /etc/named.conf
[root@server named]# systemctl restart named

第五步：进行验证

在ip地址为192.168.118.1的主机上测试得到

在ip地址为192.168.118.129的主机上测试得到
