linux上bind服务安装配置

环境redhat6.4 64bit

1.安装bind包：
yum install bind bind-libs bind-utils bind-chroot -y
[root@rhel64-64bit Desktop]# rpm -qa|grep bind|grep '^bind'
bind-chroot-9.8.2-0.62.rc1.el6.x86_64
bind-libs-9.8.2-0.62.rc1.el6.x86_64
bind-utils-9.8.2-0.62.rc1.el6.x86_64
bind-9.8.2-0.62.rc1.el6.x86_64

2.配置/etc/named.conf文件,修改下面参数：
listen-on port 53 { any; };
directory "/var/named";
allow-query { any; };

3.修改/etc/named.rfc1912.zones，加上正向解析和反向解析的文件：
zone "yoyo.com" IN {
type master;
file "yoyo.com.zone";
};

zone "12.3.2.in-addr.arpa" IN {
type master;
file "12.3.2.zone";
};

4.配置解析文件

创建并配置正向解析文件/var/named/yoyo.com.zone
$TTL 1D
yoyo.com. IN SOA yoyo.com. root (0 1H 15M 1W 1D)
yoyo.com. IN NS dns1.yoyo.com.
dns1.yoyo.com. IN A 127.0.0.1
www.yoyo.com. IN A 2.3.12.13

创建并配置反向解析文件/var/named/12.3.2.zone
$TTL 1D
@ IN SOA 12.3.2.in-addr.arpa. root (0 1H 15M 1W 1D)
@ IN NS dns1.yoyo.com.
127.0.0.1 IN PTR dns1.yoyo.com.
13 IN PTR www.yoyo.com.

5.named-checkconf检查配置文件是否有误
service named start 启动DNS服务

6.测试可以修改linux的DNS服务器指向安装的bind服务
1>setup图形化界面配置
2>/etc/sysconfig/network-scripts/ifcfg-eth0添加DNS1
3>/etc/resolv.conf 添加nameserver 生效顺序是ifcfg-eth0->resolv.conf文件

7.这里测试就不重置linux的DNS了，直接测试：

正向解析：
[root@rhel64-64bit named]# dig @127.0.0.1 www.yoyo.com

反向解析：
[root@rhel64-64bit named]# dig @127.0.0.1 -x 2.3.12.13

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.62.rc1.el6 <<>> @127.0.0.1 -x 2.3.12.13

或使用nslookup解析测试：
[root@rhel64-64bit named]# nslookup
> server 127.0.0.1
Default server: 127.0.0.1
Address: 127.0.0.1#53
> www.yoyo.com
Server:		127.0.0.1
Address:	127.0.0.1#53

Name:	www.yoyo.com
Address: 2.3.12.13
> 2.3.12.13
Server:		127.0.0.1
Address:	127.0.0.1#53

13.12.3.2.in-addr.arpa	name = www.yoyo.com.
