海山网站建设,广告策划书格式,网站空间使用方法,19互动网站建设linux下搭建DNS子域及相关授权详解forward功能是本地无法解析的域名#xff0c;转发给指定DNS服务器forward only; 所有无法解析的域名#xff0c;都转发给指定DNS服务器#xff0c;必须有解析结果forward first;无法解析的域名#xff0c;转发给指定DNS服务器#xff0c;…linux下搭建DNS子域及相关授权详解forward功能是本地无法解析的域名转发给指定DNS服务器forward only; 所有无法解析的域名都转发给指定DNS服务器必须有解析结果forward first;无法解析的域名转发给指定DNS服务器如果指定DNS服务器也无法解析再通过自己的DNS服务器向根进行转发解析forwarders { 指定DNS服务器; }; 如本地DNS无法解析向指定DNS服务器转发解析域名注意forward与forwarders同时使用2.搭建主域与子域,要求如下A.主域为willow.com,IP为1.1.1.18B.子域为a.willow.com,IP为1.1.1.20C.如果子域无法解析willow.com主域名请将转发器指向主域willow.com,其他域名自己解析D.如果子域无法的解析所有非本地域名请将转发器指向主域willow.com2.1.新增主域willow.com配置文件方法没有变化与之前博客搭建DNS一样vim /etc/named.conf新增如下内容:options {directory /var/named;allow-recursion { 1.1.1.0/24; };notify yes;also-notify { 1.1.1.19; };};zone . IN {type hint;file named.ca;};zone localhost IN {type master;file named.localhost;allow-transfer { none; };};zone 0.0.127.in-addr.arpa IN {type master;file named.loopback;allow-transfer { none; };};zone willow.com IN {type master;file willow.com.zone;allow-transfer { 1.1.1.19; };};zone 1.1.1.in-addr.arpa IN {type master;file 1.1.1.zone;allow-transfer { 1.1.1.19; };};2.2.新增willow.com.zone正向区域文件vim /var/named/willow.com.zone 主要将子域a.wilow.com的NS和A记录增加至配置文件中$TTL 600willow.com. IN SOA ns1.willow.com. root.willow.com. (201605211H10M3D1D )willow.com. IN NS ns1willow.com. IN NS ns2IN MX 10 maila IN NS ns1.ans1.a IN A 1.1.1.20ns1 IN A 1.1.1.18ns2 IN A 1.1.1.19mail.willow.com. IN A 1.1.1.23www IN A 1.1.1.30www IN A 1.1.1.31www IN A 1.1.1.32ftp IN CNAME www.willow.com.hello IN A 1.1.1.332.3.新增子域a.willow.com的named.conf文件如果子域无法的解析所有非本地域名请将转发器指向主域willow.comvim /etc/named.conf 新增如下内容options {directory /var/named;forward first; #开启转发功能forwarders { 1.1.1.18; }; #转发器指定主域};zone . IN {type hint;file named.ca;};zone localhost IN {type master;file named.localhost;allow-transfer { none; };};zone 0.0.127.in-addr.arpa IN {type master;file named.loopback;allow-transfer { none; };};zone a.willow.com {type master;file a.willow.com.zone;};2.4.新增子域a.willow.com的正向区域文件vim /var/named/a.willow.com,新增如下内容:$TTL 600a.willow.com. IN SOA ns1.a.willow.com. root.a.willow.com. (201605161H10M3D1D )a.willow.com. IN NS ns1IN MX 10 mailns1 IN A 1.1.1.20mail IN A 1.1.1.223www IN A 1.1.1.224以上子域授权等DNS服务器建立完成,可测试使用并正常2.5.如果子域无法解析willow.com主域名请将转发器指向主域willow.com,其他域名自己解析仅修改子域主配置文件named.confoptions {directory /var/named;};zone . IN {type hint;file named.ca;};zone localhost IN {type master;file named.localhost;allow-transfer { none; };};zone 0.0.127.in-addr.arpa IN {type master;file named.loopback;allow-transfer { none; };};zone a.willow.com {type master;file a.willow.com.zone;};zone willow.com {type forward;forward first;forwarders { 1.1.1.18; };};请注意forward和forwarders放置位置不同达到的效果不一样一个放在options中另一外放在zone命令单元中请看仔细了哈
