一、DNS服务

二、DNS配置

 [root@tk named]# yum -y install bind bind-chroot. [root@tk named]# cp /etc/named.conf /root #备份数据 [root@tk named]# vim /etc/named.conf [root@tk named]# cat /etc/named.conf    options { # 定义地址库文件存放路径 directory "/var/named"; }; zone "." IN { type hint; file "named.ca"; };  zone "test.cn" IN {  type master;  file "test.cn.zone"; }; include "/etc/named.rfc1912.zones"; include "/etc/named.root.key"; [root@tk named]#  [root@tk named]#cp -p named.localhost tedu.cn.zone  [root@tk named]# cat test.cn.zone $TTL 1D @ IN SOA @ rname.invalid. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum # 声明DNS服务器为tk test.cn. NS tk # tk解析结果为10.0.0.200 tk A 10.0.0.200 www A 1.1.1.1 [root@tk named]#  [root@gitlab yum.repos.d]# echo nameserver 10.0.0.200 > /etc/resolv.conf [root@gitlab yum.repos.d]# cat /etc/resolv.conf nameserver 10.0.0.200 [root@gitlab yum.repos.d]# nslookup www.test.cn Server: 10.0.0.200 Address: 10.0.0.200#53 Name: www.test.cn Address: 1.1.1.1 

三、多区域的DNS服务器

 [root@tk named]# cat /etc/named.conf    options { directory "/var/named"; }; logging { channel default_debug { file "data/named.run"; severity dynamic; }; }; zone "." IN { type hint; file "named.ca"; }; zone "test.cn" IN { type master; file "test.cn.zone"; };  zone "test1.cn" IN { type master; file "test1.cn.zone"; }; include "/etc/named.rfc1912.zones"; include "/etc/named.root.key"; [root@tk named]# [root@tk named]# cp -p test.cn.zone test1.cn.zone [root@tk named]# vim test1.cn.zone [root@tk named]# cat test1.cn.zone $TTL 1D @ IN SOA @ rname.invalid. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum test1.cn. NS tk tk A 10.0.0.200 www A 1.1.1.1 [root@tk named]# systemctl restart named [root@gitlab yum.repos.d]# nslookup www.test1.cn Server: 10.0.0.200 Address: 10.0.0.200#53 Name: www.test1.cn Address: 1.1.1.1 [root@gitlab yum.repos.d]#
