一、dns域名解析原理
二、dns主从同步实现过程
1.主：192.168.80.128
[root@localhost ~]# yum install bind -y
[root@localhost ~]# systemctl restart named.service
[root@localhost ~]# vim /etc/named.conf
options {
listen-on port 53 { any; };
directory "/var/named";
allow-query { any; };
allow-transfer { 192.168.80.131; };
};
zone "zhang.com." IN {
type master;
file "named.zhang.com";
};
zone "80.168.192.in-addr.arpa" IN {
type master;
file "named.192.168.80.zone";
};
[root@localhost ~]# cp -a /var/named/named.localhost /var/named/named.zhang.com
[root@localhost ~]# vim /var/named/named.zhang.com
[root@localhost ~]# cp -a /var/named/named.localhost /var/named/named.192.168.80.zone
[root@localhost ~]# vim /var/named/named.192.168.80.zone
[root@localhost ~]# systemctl restart named
2.从：192.168.80.131
[root@localhost ~]# yum install bind -y
[root@localhost ~]# systemctl start named
[root@localhost ~]# vim /etc/named.conf
options {
listen-on port 53 { any; };
directory "/var/named";
allow-query { any; };
};
zone "zhang.com" IN {
type slave;
masters { 192.168.80.128; };
file "slaves/named.zahng.com";
};
zone "80.168.192.in-addr.arpa" IN {
type slave;
masters { 192.168.80.128; };
file "slaves/named.192.168.80.zone";
};
[root@localhost ~]# systemctl restart named
[root@localhost ~]# systemctl stop firewalld
