DNS服务器的类型：
Master： 提供dns服务，并且本身含有区域文档。
Slave： 和Master一起提供dns服务，当Master服务器上的名字地址对更改的时候，会自动更新Slave服务器来达到同步。
Cache-only： 没有自己的区域文档，只是帮助客户段向外部dns请求查询，然后将查到的结果保存到他的缓存中。

1，pre-configuration check
dig -t axfr example.com @192.168.0.254
host -l example.com 192.168.0.254
2,安装包
yum install -y bind bind-utils bind-chroot caching-nameserver
3，编辑named.conf
zone "example.com" IN {
type slave;
masters { 192.168.0.254; };
file "slaves/example.com.zone";
forwarders {};
};
4, 修改文件权限
[root@station10 etc]# ls -lZ
-rw-r--r-- root root system_u:object_r:locale_t localtime
-rw-r----- root named system_u:object_r:named_conf_t named.caching-nameserver.conf
-rw-r----- root root root:object_r:named_conf_t named.conf
-rw-r----- root named system_u:object_r:named_conf_t named.rfc1912.zones
-rw-r--r-- root named system_u:object_r:dnssec_t rndc.key
[root@station10 etc]# chown root:named named.conf
[root@station10 etc]# chmod 640 !$
chmod 640 named.conf
[root@station10 etc]# ls -lZ
-rw-r--r-- root root system_u:object_r:locale_t localtime
-rw-r----- root named system_u:object_r:named_conf_t named.caching-nameserver.conf
-rw-r----- root named root:object_r:named_conf_t named.conf
-rw-r----- root named system_u:object_r:named_conf_t named.rfc1912.zones
-rw-r--r-- root named system_u:object_r:dnssec_t rndc.key
[root@station10 etc]#
5，启动服务
[root@station10 etc]# service named configtest
zone localdomain/IN: loaded serial 42
zone localhost/IN: loaded serial 42
zone 0.0.127.in-addr.arpa/IN: loaded serial 1997022700
zone 0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa/IN: loaded serial 1997022700
zone 255.in-addr.arpa/IN: loaded serial 42
zone 0.in-addr.arpa/IN: loaded serial 42
[root@station10 etc]# service named restart
6，查看产生的文件
[root@station10 etc]# cd /var/named/chroot/var/named/slaves/
[root@station10 slaves]# ls -lZ
-rw-r--r-- named named root:object_r:named_cache_t example.com.zone
[root@station10 slaves]# cat example.com.zone
7，测试
[root@station10 slaves]# host -r station10.example.com localhost
Using domain server:
Name: localhost
Address: 127.0.0.1#53
Aliases:
station10.example.com has address 192.168.0.10
[root@station10 slaves]# dig +norecurse station10.example.com @localhost
; <<>> DiG 9.3.3rc2 <<>> +norecurse station10.example.com @localhost
