b. 创建正向解析域：vim /etc/named/zones/lee.com.zone

$TTL 1D
@       IN      SOA     ns1.lee.com. admin.lee.com. (
3         ; Serial

)
IN NS ns1.lee.com.
ns1.lee.com. IN A 192.168.8.81

blog.lee.com. IN A 192.168.8.82
shop.lee.com. IN A 192.168.8.83

c. 创建反向解析域：vim /etc/named/zones/192.168.zone

$TTL 1D
@       IN      SOA     ns1.lee.com. admin.lee.com. (
3         ; Serial
604800     ; Refresh

2419200     ; Expire
604800 
)
IN NS ns1.lee.com.
81.8 IN PTR ns1.lee.com.
81.8 IN PTR www.lee.com.
82.8 IN PTR blog.lee.com.
83.8 IN PTR shop.lee.com.

named-checkconf

b. 检查正向解析域的语法：

named-checkzone lee.com /etc/named/zones/lee.com.zone

c. 检查反向解析域的语法：

named-checkzone 192.168.in-addr.arpa /etc/named/zones/192.168.zone

systemctl  start  named

nameserver  192.168.8.81
