標籤：linux 伺服器 網域名稱 dns伺服器
案例環境：
主網域名稱伺服器：ns1.zdj.com，172.17.0.142
從網域名稱伺服器：ns2.zdj.com，172.17.0.37
兩台伺服器均能夠提供 zdj.com 地區的網域名稱解析
主網域名稱伺服器：1. ip:172.17.0.142
[[email protected] var]# vim /var/named/chroot/etc/named.rfc1912.zones ----添加下列內容
zone "zdj.com" IN {
type master;

};
zone "0.17.172.in-addr.arpa" IN {
