centos6.5 dns配置

一. 软件包安装

[root@centos6 cdrom]# yum install bind
[root@centos6 cdrom]# yum install bind-chroot

二. 配置DNS主配置文件

1. 把 /etc目录下面的named* 复制到/var/named/chroot/etc/下

[root@centos6 etc]# cp -a named* /var/named/chroot/etc/

2. 编辑named.conf文件，编辑前最好先备份

[root@centos6 etc]# cd /var/named/chroot/etc
[root@centos6 etc]# cp -p named.conf named.confbak
[root@centos6 etc]# vi named.conf

修改为

listen-on port 53 { any; };

//listen-on-v6 port 53 {::1; };

allow-query { any; };

3. 配置正向反向配置文件

[root@centos6 etc]# cd /var/named/chroot/etc
[root@centos6 etc]# cp -p named.rfc1912.zones named.rfc1912.zonesbak
[root@centos6 etc]# vi named.rfc1912.zones

添加一下内容：

zone "example.com" IN{

type master;

file "example.com.zone";

allow-update {none;};

};

zone "48.168.192.in-addr.arpa" IN {

type master;

file "192.168.48.zone";

allow-update {none;};

};

4. 复制 /var/named目录下的文件到 /var/named/chroot/var/named/

[root@centos6 etc]# cd /var/named
[root@centos6 named]# cp -a named* /var/named/chroot/var/named/

5.添加正向文件和反向文件，注意与3中文件名称一致

[root@centos6 named]# cd /var/named/chroot/var/named
[root@centos6 named]# touch example.com.zone
[root@centos6 named]# vi example.com.zone

正向文件内容如下：

[root@centos6 named]# cat example.com.zone
$TTL 86400
@ IN SOA dns.example.com. root.example.com. (
2011091200 ; serial
3H ; refresh
1H ; retry
1W ; expire
0) ; minimum

@ IN NS dns.example.com.

dns IN A 192.168.48.10

www IN A 192.168.48.10

添加反向文件：

[root@centos6 named]# touch 192.168.48.zone
[root@centos6 named]# vi 192.168.48.zone

反向文件内容如下：

[root@centos6 named]# cat 192.168.48.zone
$TTL 86400
@ IN SOA dns.example.com. root.example.com. (
2011091200 ; serial
3H ; refresh
1H ; retry
1W ; expire
0) ; minimum

@ IN NS dns.example.com.
10.48.168.192.in-addr.arpa. IN PTR dns.example.com.
6 IN PTR www.example.com.

6. 检查正向文件和反向文件配置是否有误

[root@centos6 named]# named-checkzone 192.168.48.zone /var/named/chroot/var/named/192.168.48.zone
/var/named/chroot/var/named/192.168.48.zone:10: ignoring out-of-zone data (10.48.168.192.in-addr.arpa)
zone 192.168.48.zone/IN: loaded serial 2011091200
OK
[root@centos6 named]# named-checkzone example.com /var/named/chroot/var/named/example.com.zone
zone example.com/IN: loaded serial 2011091200
OK

ok即为文件配置正确

7. 修改正向文件与反向文件所属组

[root@centos6 named]# chgrp named /var/named/chroot/var/named/192.168.48.zone
[root@centos6 named]# chgrp named /var/named/chroot/var/named/example.com.zone

8. 测试dns服务能否正常开启

[root@centos6 named]# service named status
rndc: neither /etc/rndc.conf nor /etc/rndc.key was found
named is stopped
[root@centos6 named]# service named start
Generating /etc/rndc.key:[  OK  ]
Starting named: [  OK  ]
[root@centos6 named]# nslookup 192.168.48.10
Server:         127.0.0.1
Address:        127.0.0.1#53

10.48.168.192.in-addr.arpa      name = dns.example.com.
[root@centos6 named]# nslookup www.example.com
Server:         127.0.0.1
Address:        127.0.0.1#53

Name:   www.example.com
Address: 192.168.48.10
