DNS 搭建

拓扑图

1、配置yum

[rhel]

name=rhel

baseurl=file:///mnt/Server

enabled=1

gpgcheck=0

2、安装软件

[root@localhost named]# yum install -y bind* caching-nameserver 

3、设置配置文件

[root@localhost etc]# cat named.conf

options {

 directory "/var/named";

};

zone "shareclouds.com" IN{

 type master;

 file "shareclouds.com.zone";

};

zone "51.10.10.in-addr.arpa" {

 type master;

 file "shareclouds.com.10.10.51";

};

[root@localhost etc]# cd ../var/named/

[root@localhost named]# cat shareclouds.com.zone

$TTL 86400     

shareclouds.com.  IN SOA   sharelcouds.com. root.sharelcouds.com. ( 

                                     42 ; serial (d. adams)

                                     3H ; refresh

                                     15M ; retry

                                     1W ; expiry

                                     1D ) ; minimum

                   IN NS shareclouds.com.

www           IN A 10.10.51.61

portal         IN A 10.10.51.11

gateway     IN A 10.10.51.12

router         IN A 10.10.51.13

replay         IN A 10.10.51.14

                   IN A 127.0.0.1

                   IN AAAA ::1

[root@localhost named]# cat shareclouds.com.10.10.51

$TTL 86400

@ IN SOA @ root (

                                      42 ; Serial

                                      3H ; Refresh

                                      15M ; Retry

                                      1W ; Expire

                                      1D ) ; Minimum

@ IN NS shareclouds.com.

61 IN PTR www.shareclouds.com.

11 IN PTR portal.shareclouds.com.

12 IN PTR gateway.shareclouds.com.

13 IN PTR router.shareclouds.com.

14 IN PTR replay.shareclouds.com.

3、配置dns地址

[root@localhost named]# cat /etc/resolv.conf

search localhost

nameserver 10.10.51.61

4、测试配置结果

[root@localhost named]# host portal.shareclouds.com

portal.shareclouds.com has address 10.10.51.11

[root@localhost named]# host 10.10.51.11

11.51.10.10.in-addr.arpa domain name pointer portal.shareclouds.com.

[root@localhost named]# nslookup portal.shareclouds.com

Server: 10.10.51.61

Address: 10.10.51.61#53

Name: portal.shareclouds.com

Address: 10.10.51.11
