Centos6.5 DNS配置

服务器端：192.168.186.130

1、安装

# yum -y install bind*

2、主要配置文件

 [root@localhost named]# vim /etc/named.conf
 // Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
 // server as a caching only nameserver (as a localhost DNS resolver only).
 //
 // See /usr/share/doc/bind*/sample/ for example named configuration files.
 //  

 options {
         listen-on port  { any; };//开启监听端口53并接受任意IP连接
         #listen-on-v6 port  { ::; };
         directory       "/var/named"; //正向反向区域文件存放目录
         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     { 0.0.0.0/; }; //允许任意IP查询
         recursion yes;  

         dnssec-enable yes;
         dnssec-validation yes;
         dnssec-lookaside auto;  

         /* Path to ISC DLV key */
         bindkeys-file "/etc/named.iscdlv.key";  

         managed-keys-directory "/var/named/dynamic";
 };  

 logging {
         channel default_debug {
                 file "data/named.run";
                 severity dynamic;
         };
 };  

 zone "." IN {
         type hint;
         file "named.ca";
 };  

 include "/etc/named.rfc1912.zones";
 include "/etc/named.root.key";  

3、创建正反向区域

 [root@localhost named]# vim /etc/named.rfc1912.zones
 // named.rfc1912.zones:
 //
 // Provided by Red Hat caching-nameserver package
 //
 // ISC BIND named zone configuration for zones recommended by
 // RFC 1912 section 4.1 : localhost TLDs and address zones
 // and http://www.ietf.org/internet-drafts/draft-ietf-dnsop-default-local-zones-02.txt
 // (c)2007 R W Franks
 //
 // See /usr/share/doc/bind*/sample/ for example named configuration files.
 //  

 zone "gxdemo.com" IN {
         type master;
         file "named.gxdemo.com";
         allow-update { none; };
 };  

 zone "186.168.192.in-addr.arpa" IN {
         type master;
         file "192.168.186.arpa";
         allow-update { none; };
 };  

4、配置正向文件

 [root@localhost named]# vim /var/named/named.gxdemo.com
 $TTL 1D
 @       IN SOA  gxdemo.com. rname.invalid. (
                                                ; serial
                                         1D      ; refresh
                                         1H      ; retry
                                         1W      ; expire
                                         3H )    ; minimum
         NS      @
         A       127.0.0.1
         AAAA    ::
 gx IN A 192.168.186.36  

5、配置反向文件

 [root@localhost named]# vim /var/named/192.168..arpa
 $TTL 1D
 @       IN SOA  gxdemo.com. rname.invalid. (
                                                ; serial
                                         1D      ; refresh
                                         1H      ; retry
                                         1W      ; expire
                                         3H )    ; minimum
         NS      @
         AAAA    ::
       PTR     gx.  

6、修改文件所属组

 [root@localhost named]chown root:named 192.168..arpa
 [root@localhost named]chown root:named named.gxdemo.com

7、修改DNS文件

 [root@localhost named]# vim /etc/resolv.conf
 nameserver 192.168.186.130  

8、测试

查看是哪个DNS服务器

 [root@localhost named]# dig -t ns gx.gxdemo.com

 ; <<>> DiG 9.8.2rc1-RedHat-9.8.-0.62.rc1.el6_9. <<>> -t ns gx.gxdemo.com
