Bind基本配置

Bind基本配置

1、安装bind

下载bind-9.7.2-P2

#tar xvf bind-9.7.2.-P2

#./configure –prefix=/app/named --disable-ipv6 --disable-openssl-version-check --enable-threads

#make

#make install

2、配置bind

生成rndc.conf文件

#/app/named/sbin/rndc-confgen > /app/named/etc/rndc.conf

生成named.conf文件

#tail -10 rndc.conf | head -9 | sed s/#\ //g > named.conf

创建/var/named，并且创建几个文件

第一：localhost.zone

$TTL    86400

$ORIGIN localhost.

@      1D IN SOA       @ root (

42              ; serial (d. adams)

                     3H              ; refresh

                     15M             ; retry

                     1W              ; expiry

                     1D )            ; minimum

1D IN NS        @

         1D IN A         127.0.0.1

第二：named.local

$TTL    86400

@       IN      SOA     localhost. root.localhost.  (

                                      1997022700 ; Serial

                                      28800      ; Refresh

                                      14400      ; Retry

                                      3600000    ; Expire

                                      86400 )    ; Minimum

        IN      NS      localhost.

1       IN      PTR     localhost.

第三：named.root

#/app/named/bin/dig > /var/named/named.root

第四：需要解析的域名test.zone

$ttl    1D

@          IN SOA  test.com.  root.test.com. (

 

                           1053891162

                             3H

                            15M

                             1W

                             1D )

 

                    IN NS                    dns.test.com.   #注意此处为dns服务器机器名

                    IN MX    5         dns.test.com.   #注意此处为dns服务器机器名

www                IN A          192.168.0.66

第五：域名的反向解析test.local

$TTL 86400

@ IN SOA test.com. root.test.com.(

20031001;

7200;

3600;

43200;

86400);

@ IN NS test.com.

82 IN PTR

第六：补充named.conf内容

options { 

directory "/var/named";                                  #named区文件目录 

pid-file "named.pid";                               #进程id文件名 

}; 

zone "." IN {

        type hint;

        file "named.root";

};

zone "localhost" IN {

        type master;

        file "localhost.zone";

        allow-update { none; };

};

zone "0.0.127.in-addr.arpa" IN {

        type master;

        file "named.local";

        allow-update { none; };

};

zone "test.com" IN {

        type master;

        file "test.zone";

        allow-update { none; };

};

zone "0.168.192.in-addr.arpa" IN {

        type master;

        file "test.local";

        allow-update { none; };

};

 

3、运行bind

#/app/named/sbin/named -gc /app/named/etc/named.conf

参数-gc可以显示named运行情况。

 

扩展一下，配置bind主从，很简单

在从dns服务器的named.conf中，相应的域名配置中

zone "test.com" IN {

        type master;

        file "test.zone";

        allow-update { none; };

        };

改为（红字部分）

zone "test.com" IN {

        type slave;

        file "test.zone";

        allow-update { none; };

        masters{主dns地址;};

};

更新主dns后，kill -1 bind进程，辅dns就会自动更新
