1,主服务器的配置
关闭防火墙和Linux的安全程序
[root@localhost ~]# systemctl stop firewalld.service #关闭防火墙
[root@localhost ~]# setenforce 0 #关闭安全策略
下载DNS
[root@localhost ~]# dnf install bind -y
配置操作
bash
[root@localhost ~]# vim /etc/named.conf
options{
listen-on port 53 { 192.168.85.136; };
directory "/var/named";
allow-query { any; };
allow-transfer { 192.168.85.135; };
};
zone "openlab.com" IN {
type master;
file "named.openlab.com";
};
zone "85.168.192.in-addr.arpa" IN {
type master;
file "named.192";
allow-update { none; };
};
2,从服务器的配置
关闭防火墙和Linux的安全程序
[root@localhost ~]# systemctl stop firewalld.service #关闭防火墙
[root@localhost ~]# setenforce 0 #关闭安全策略
下载DNS
[root@localhost ~]# dnf install bind -y
配置操作
bash
options{
listen-on port 53 { 192.168.85.135; };
directory "/var/named/slaves";
allow-query { any; };
};
zone "openlab.com" IN {
type slave;
file "named.openlab.com";
masters { 192.168.85.136; };
};
zone "85.168.192.in-addr.arpa" IN {
type slave;
file "named.192";
masters { 192.168.85.136; };
};
