★增加一个域名（zone）
- vim /etc/named.conf 修改主配置文件
zone "hera.com" IN {
type master;
file "hera.com.zone";
};
zone "16.168.192.in-addr.arpa" IN { <== 反解析zone，IP是反着写的，192.168.16.*
type master;
file "192.168.zone";
};
- 编辑zone文件: vim /var/named/hera.com.zone
增加以下内容：
$TTL 600 <== 600秒过期
@ IN SOA hera.com. root.hera.com. (
2013081601
1H
10M
7D
1D
)
IN NS ns.hera.com.
IN MX 10 mail.hera.com.
ns IN A 192.168.16.100
www IN A 192.168.16.100
mail IN A 192.168.16.10
bbs IN CNAME www.hera.com. - 编辑反解析文件: vim /var/named/192.168.zone
增加以下内容：
$TTL 600
@ IN SOA ns.hera.com. root.hera.com. (
2013081601
1H
10M
7D
1D
)
@ IN NS ns.hera.com.
10 IN PTR ns.hera.com.
11 IN PTR mail.hera.com.
73 IN PTR www.hera.com. - 检测配置文件是否有问题
要注意，检测之前我们一定要先进入/var/named下
named-checkzone "hera.com" hera.com.zone
[[email protected] named]# named-checkzone "hera.com" hera.com.zone
zone hera.com/IN: loaded serial 2013081601
OK
named-checkzone "16.168.192.in-addr.arpa" 192.168.zone
[[email protected] named]# named-checkzone "16.168.192.in-addr.arpa" 192.168.zone
zone 16.168.192.in-addr.arpa/IN: loaded serial 2013081601
OK
- 重启named服务：service named restart
- 测试：
