bind实现智能解析view

1、 软件列表
BIND 9.3.2
ftp://ftp.isc.org/isc/bind9/9.3.2/bind-9.3.2.tar.gz
ftp://ftp.isc.org/isc/bind9/9.4.0a6/bind-9.4.0a6.tar.gz
2、 安装BIND 9
安装BIND9：
# tar zxvf bind-9.3.2.tar.gz
# cd bind-9.3.2
# ./configure --prefix=/usr/local/named --disable-ipv6
# make && make install
建立BIND用户：
# groupadd bind
# useradd -g bind -d /usr/local/named -s /sbin/nologin bind
创建配置文件目录：
# mkdir –p /usr/local/named/etc
# chown bind:bind /usr/local/named/etc
# chmod 700 /usr/local/named/etc

二、named.conf的配置

创建主要的配置文件：
# vi /usr/local/named/etc/named.conf
===========================named.conf=======================
acl "trust-lan" { any; };

options {
    directory "/usr/local/named/etc/";
    pid-file "/var/run/named/named.pid";
    version "0.0.0";
    auth-nxdomain no;
    allow-query { any; };
    allow-transfer { "trust-lan"; };
    allow-notify { "trust-lan"; };
};

logging {

channel warning { file "/var/log/named/dns_warnings" versions 3 size 1240k;
severity warning;
print-category yes;
print-severity yes;
print-time yes;
};

channel general_dns
{ file "/var/log/named/dns_logs" versions 3 size 1240k;
   severity info;
print-category yes;
print-severity yes;
print-time yes;
};

category default { warning; };
category queries { general_dns; };
};

acl "telecom" {
58.154.0.0/15;
58.192.0.0/12;
59.64.0.0/12;
116.13.0.0/16;
116.56.0.0/15;
118.202.0.0/15;
118.228.0.0/15;
118.230.0.0/16;
121.48.0.0/15;
121.52.160.0/19;
121.192.0.0/14;
121.248.0.0/14;
122.204.0.0/14;
125.216.0.0/13;
162.105.0.0/16;
166.111.0.0/16;
202.4.128.0/19;
202.38.64.0/18;
202.38.140.0/23;
202.38.184.0/21;
202.38.192.0/18;
202.112.0.0/13;
202.120.0.0/15;
202.127.216.0/21;
202.127.224.0/19;
202.179.240.0/20;
202.192.0.0/12;
203.91.120.0/21;
210.25.0.0/17;
210.25.128.0/18;
210.26.0.0/15;
210.28.0.0/14;
210.32.0.0/12;
211.64.0.0/13;
211.80.0.0/13;
218.192.0.0/13;
219.216.0.0/13;
219.224.0.0/13;
219.242.0.0/15;
219.244.0.0/14;
222.16.0.0/12;
222.192.0.0/12;
};

view "view_telecom" {
  match-clients { telecom; };

zone "." {
    type hint;
    file "named.root";
};

zone "localhost" IN {
     type master;
     file "localhost.zone";
     allow-update { none; };
};

zone "0.0.127.IN-ADDR.ARPA" {
     type master;
     file "localhost.rev";
};

include "master/telecom.def";
};

view "view_any" {
     match-clients { any; };

zone "." {
     type hint;
     file "named.root";
};

zone "localhost" IN {
        type master;
        file "localhost.zone";
        allow-update { none; };
};

zone "0.0.127.IN-ADDR.ARPA" {
     type master;
     file "localhost.rev";
};

include "master/cnc.def";
};

添加完成后，保存。

三、更新根区文件：

# cd /usr/local/named/etc/
# wget ftp://ftp.internic.org/domain/named.root
创建PID和日志文件：
# mkdir /var/run/named/
# chmod 777 /var/run/named/
# chown bind:bind /var/run/named/
# mkdir /var/log/named/
# touch /var/log/named/dns_warnings
# touch /var/log/named/dns_logs
# chown bind:bind /var/log/named/*
# mkdir master
# touch master/cnc.def
# touch master/telecom.def
生成rndc-key：
# cd /usr/local/named/etc/
# ../sbin/rndc-confgen > rndc.conf
把rndc.conf中：
# Use with the following in named.conf, adjusting the allow list as needed:
后面以的部分加到/usr/local/named/etc/named.conf中并去掉注释
运行测试：
# /usr/local/named/sbin/named -gc /usr/local/named/etc/named.conf &
状态检查：
# /usr/local/named/sbin/rndc status


四、建立启动脚本：

# vi /etc/init.d/named
============================== named.sh============================
#!/bin/bash
#
# named        a network name service.
#
#
# chkconfig: 545 35 75
# description: a name server
#
if [ `id -u` -ne 0 ]
then
echo "ERROR:For bind to port 53,must run as root."
exit 1
fi
case "$1" in
start)
if [ -x /usr/local/named/sbin/named ]; then
/usr/local/named/sbin/named -u bind -c /usr/local/named/etc/named.conf && echo . && echo 'BIND9 server started.'
fi
;;
stop)
kill `cat /var/run/named/pid` && echo . && echo 'BIND9 server stopped.'
;;
restart)
echo .
echo "Restart BIND9 server"
$0 stop
sleep 10
$0 start
;;
*)
echo "$0 start | stop | restart"
;;
esac
===============================named.sh============================
# chmod 755 /etc/init.d/named
# chown root:root /etc/init.d/named
# chkconfig --add named
# chkconfig named on


五、添加一个NS

       在域名的管理网站上，设定NS服务器为你安装的DNS


六、添加一个域名

# cd /usr/local/named/etc/master
# mkdir cnc
# mkdir telecom
# vi cnc.def
添加
zone "724cn.com" {
type master;
file "master/cnc/724cn.com";
};
# vi telecom.def
添加
zone "724cn.com" {
type master;
file "master/telecom/724cn.com";
};
添加网通的解析，解析到的IP为61.45.55.78
#vi cnc/724cn.com
添加
$TTL 3600
$ORIGIN 724cn.com.
@ IN SOA ns.724cn.com. root.ns.724cn.com.(
2005121013 ;Serial
3600 ; Refresh ( seconds )
900 ; Retry ( seconds )
68400 ; Expire ( seconds )
15 );Minimum TTL for Zone ( seconds )
;
@ IN NS ns.724cn.com.
@ IN A 211.162.106.9
www IN A 211.162.106.9
;
;end
添加电信的解析，解析到的IP为210.75.1.178
#vi telecom/724cn.com
添加
$TTL 3600
$ORIGIN 724cn.com.
@ IN SOA ns.724cn.com. root.ns.724cn.com.(
2005121013 ;Serial
3600 ; Refresh ( seconds )
900 ; Retry ( seconds )
68400 ; Expire ( seconds )
15 );Minimum TTL for Zone ( seconds )
;
@ IN NS ns.724cn.com.
@ IN A 211.162.106.254
www IN A 211.162.106.254
;
;end
#/usr/local/named/sbin/rndc reload
OK，到此你的DNS服务器就算是跑起来了。试一下分别用网通和电信的线路ping一下吧.
