DNS 服务 (系统需要配置静态 IP 地址)
yum install bing* -y
一、配置 NDS 域名解析;
直接添加以下内容:
[[email protected] ~]# cat /etc/named.conf zone "wangxiaojing.com" IN { type master; file "wangxiaojing.com.zone"; allow-update{none;}; }; zone "2.16.172.in-addr.arpa" IN { type master; file "2.16.172.local"; allow-update{none;}; };
二、配置正向解析
[[email protected] ~]# cat /var/named/wangxiaojing.com.zone $TTL 1D @ IN SOA @ dns.wangxiaojing.com. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS @ A 127.0.0.1 AAAA ::1 IN NS dns.wangxiaojing.com. IN MX 10 dns.wangxiaojing.com. dns IN A 172.16.2.18 mail IN CNAME dns pop3 IN CNAME dns smtp IN CNAME dns imap4 IN CNAME dns
三、配置反向解析
[[email protected] ~]# cat /var/named/2.16.172.local $TTL 1D @ IN SOA @ dns.wangxiaojing.com. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS @ A 127.0.0.1 AAAA ::1 IN NS dns.wangxiaojing.com. 18 IN PTR dns.wangxiaojing.com.
四、启动测试;
chkconfig named on service named start
五、配置 /etc/resolv.conf
(bind 重启之后配置会丢失,编辑保存就行)
search wangxiaojing.com nameserver 172.16.2.18 nameserver 8.8.8.8 nameserver 8.8.4.4
六、检测 NDS 解析:
[[email protected] ~]# nslookup -qt=mx mail.wangxiaojing.com *** Invalid option: qt=mx Server: 172.16.2.18 Address: 172.16.2.18#53 mail.wangxiaojing.com canonical name = dns.wangxiaojing.com. Name: dns.wangxiaojing.com Address: 172.16.2.18
