[root@localhost ~]# 
 
# 安装 bind - 10.4.7.11
[root@localhost ~]# yum install bind -y
 
# 查看版本
[root@localhost ~]# rpm -qa bind
bind-9.11.4-26.P2.el7_9.9.x86_64
 
# 1-主配置
[root@localhost ~]# vim /etc/named.conf 
 
# 修改的地方
listen-on port 53 { 192.168.31.31; };
allow-query     { any; };
# 添加了一个网关地址
forwarders      { 192.168.31.1 };
# 使用yes 采用递归
recursion yes;
# 这两个设置成 no
dnssec-enable no;
dnssec-validation no;
 
 
# 检查配置是否有问题
[root@localhost ~]# named-checkconf
 
# 2-配置区域文件
[root@localhost named]# vim /etc/named.rfc1912.zones 
 
# 配置两个域，添加如下内容
zone "host.com" IN {
        type master;
        file "host.com.zone";
        allow-update { none; };
};
zone "od.com" IN {
        type master;
        file "od.com.zone";
        allow-update { none; };
};
 
# 3-配置区域数据文件
[root@localhost ~]# cd /var/named/
 
[root@localhost named]# cp -a named.localhost host.com.zone
 
[root@localhost named]# vim host.com.zone 
$ORIGIN host.com.
