#启动服务
# service named start
Redirecting to /bin/systemctl start named.service
#修改配置文件。
#在修改之前，先进行备份，这是一个好习惯
# cp /etc/named.conf /etc/named.conf.bak
# vi /etc/named.conf
#建议：先将原有配置注释，再写新的配置，如下所示
options {
//listen-on port 53 { 127.0.0.1; };
listen-on port 53 { any; };
#将 dnssec 设置"yes"修改为 no，示例如下：
//dnssec-enable yes;
dnssec-enable no;
//dnssec-validation yes;
dnssec-validation no;
dnssec-lookaside auto;
#将 allow-query 设置修改为 any，示例如下：
//allow-query { localhost; };
allow-query { any; };
allow-transfer { 192.168.188.11; 192.168.188.12; };#设置辅助DNS的地址
forwarders {202.102.224.68; 202.102.227.68; }; # 配置DNS转发器
};
// LEAUS Add 添加正向ZONE
zone "bigcloud.local" IN {
type master;
file "bigcloud.zone";
};
//添加反向ZONE
zone "0.0.10.in-addr.arpa" IN {
#此处IP地址根据自己所设置的网段不同而更改
type master;
file "10.0.0.zone";
};
#创建ZONE文件
#cd /var/named/
