BIND 9 配置语法简介http://bbs.linuxtone.org/thread-2076-1-1.html
注对于配置智能DNS主要用途为1、解决网通与电信问题 2、实现区域规划不同区域访问各自最近的服务器下面以解决网通与电信连接问题的配置。至于实现2的功能只需稍加更改即可。
一、DNS服务器安装......................................................................................... 1
二、named.conf的配置....................................................................................... 2
三、更新根区文件.......................................................................................... 3
四、建立启动脚本.......................................................................................... 4
五、添加一个NS............................................................................................... 5
六、添加一个域名.............................................................................................. 5
附获取IP地址范围方法:................................................................................. 7
一、DNS服务器安装
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 ?Cp /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" { 127.0.0.1/8; 192.168.0.0/16;};
options {
directory "/usr/local/named/etc/"; //启动服务器的目录
pid-file "/var/run/named/named.pid";
version "0.0.0"; //服务器的真实版本号
datasize 40M;
allow-transfer {
"trust-lan";};
recursion yes; //是否代表客户机查询其他DNS服务器
allow-notify {
"trust-lan";
};
allow-recursion {
"trust-lan";
};
auth-nxdomain no;
forwarders { //指向外部转发器
211.162.106.9;
211.162.106.254;};
};
logging { //指定日志记录分类和他们的目标位置
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; };
};
zone "." {
type hint;
file "named.root";
};
acl "CNC" {
58.16.0.0/16 ;
58.17.0.0/17;
58.17.128.0/17;
58.18.0.0/16;
58.19.0.0/16;
58.20.0.0/16;
58.21.0.0/16;
61.45.0.0/16;
注这些根据情况输入IP地址段
};
view "view_cnc" {
match-clients { CNC; };
zone "." {
type hint;
file "named.root";
};
zone "0.0.127.IN-ADDR.ARPA" {
type master;
file "localhost.rev";
};
include "master/cnc.def"; 将其他文件包含到本配置文件当中
};
view "view_any" {
match-clients { any; };
zone "." {
type hint;
file "named.root";
};
zone "0.0.127.IN-ADDR.ARPA" {
type master;
file "localhost.rev";
};
include "master/telecom.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.
附获取IP地址范围方法:
1、 利用shell程序获取IP地址段
#!/bin/sh
FILE=/root/study/apnic/ip_apnic
rm -f $FILE
wget http://ftp.apnic.net/apnic/stats/apnic/delegated-apnic-latest -O $FILE
grep 'apnic|CN|ipv4|' $FILE | cut -f 4,5 -d'|'|sed -e 's/|/ /g' | while read ip cnt
do
echo $ip:$cnt
mask=$(cat << EOF | bc | tail -1
pow=32;
define log2(x) {
if (x<=1) return (pow);
pow--;
return(log2(x/2));
}
log2($cnt)
EOF)
echo $ip/$mask>> cn.net
NETNAME=`whois $ip@ whois.apnic.net | sed -e '/./{H;$!d;}' -e 'x;/netnum/!d' |grep ^netname | sed -e 's/.*: \(.*\)/\1/g' | sed -e 's/-.*//g'`
case $NETNAME in
CNC)
echo $ip/$mask >> CNCGROUP
;;
CHINANET|CNCGROUP)
echo $ip/$mask >> $NETNAME
;;
CHINATELECOM)
echo $ip/$mask >> CHINANET
;;
*)
echo $ip/$mask >> OTHER
;;
esac
done
2、 可以利用网上的资料下面是最新的信息然后利awk行成地址段即可。
wget http://218.66.103.230/***_route/cnc.new 新的网通路由表
wget http://218.66.103.230/***_route/chinanet.new 新的电信路由表
