linux+bind快速配置简单dns
一、安装
# yum install bind
二、配置
# vi /etc/named.conf
输入以下内容：
options {
directory "/var/named";
pid-file "/var/named/named.pid";
forwarders { 202.101.224.67; 202.101.224.68; };
allow-query { any; };
};
zone "." IN {
type hint;
file "named.root";
};
zone "0.0.127.in-addr-arpa" IN {
type master;
file "named.local";
allow-update { none; };
};
zone "df3c.com" IN {
type master;
file "named.df3c.com";
allow-update { none; };
};
zone "1.168.192.in-addr-arpa" IN {
type master;
file "named.1.168.192";
allow-update { none; };
};
# dig /var/named/named.root
# vi /var/named/named.local
输入以下内容：
$TTL 3h 0.0.127.in-addr.arpa. IN SOA terminator.df3c.edu. [email protected]. ( 1 ; Serial 3h ; Refresh after 3 hours 1h ; Retry after 1 hours 1w ; Expire after 1 week 1h ) ; Negative caching TTL of 1 hour 1.0.0.127.in-addr.arpa. IN PTR localhost.
# vi /var/named/named.df3c.com
输入以下内容：
$TTL 3h df3c.com. IN SOA ns.df3c.com. [email protected]. ( 1 ; Serial 3h ; Refresh after 3 hours 1h ; Retry after 1 hours 1w ; Expire after 1 week 1h ) ; Negative caching TTL of 1 hour df3c.com. IN NS ns.df3c.com. df3c.com. IN MX 10 mail ns.df3c.com. IN A 192.168.1.226 www IN A 192.168.1.226 * IN A 192.168.1.240
# vi /var/named/named.1.168.192
输入以下内容：
$TTL 3h 1.168.192.in-addr.arpa. IN SOA ns.df3c.com. [email protected]. ( 1 ; Serial 3h ; Refresh after 3 hours 1h ; Retry after 1 hours 1w ; Expire after 1 week 1h ) ; Negative caching TTL of 1 hour 1.168.192.in-addr.arpa. IN NS ns.df3c.com. 226.1.168.192.in-addr.arpa. IN PTR ns.df3c.com.
三、启动
# /usr/sbin/named -g &
注：-g显示启动时的日志，一边分析启动过程出现错误的原因。
# ps -eaf|grep named
# netstat -an |grep :53
四、开启dns防火墙
# iptables -I INPUT -p tcp --dport 53 -j ACCEPT
# iptables -I INPUT -p udp --dport 53 -j ACCEPT
# /etc/init.d/iptables save
# service iptables restart
# /etc/rc.d/init.d/iptables status
