linux 下内网DNS搭建

 

wget 下载bind，我下载的是bind-9.3.0b2.tar.gz

进入目录解压缩
[root@linux root]#tar xfz bind-9.3.0b2.tar.gz
进如刚解压出来的目录
[root@linux root]# cd bind-9.3.0b2
编译配置
[root@linux bind-9.3.0b2]#./configure --prefix=/usr/local/named --enable-threads #--enable-threads开启多线程处理能力
[root@linux bind-9.3.0b2]#make
[root@linux bind-9.3.0b2]#make install
进入/usr/local/named 建立etc目录
[root@linux bind-9.3.0b2]#cd /usr/local/named
[root@linux named]# mkdir etc
生成rndc控制命令的key文件
[root@linux named]# sbin/rndc-confgen > etc/rndc.conf
从rndc.conf文件中提取named.conf用的key
root@linux named]# cd etc
[root@linux etc]# tail -10 rndc.conf | head -9 | sed s/#\ //g > named.conf
自动在/usr/local/named/etc 生成named,conf文件
建立区文件目录
[root@linux etc]# mkdir /var/named
进入/var/named
[root@linux etc]# cd /var/named
建立localhost.zone文件
[root@linux named]#vi 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

建立named.local文件
[root@linux named]#vi 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.


dig命令直接生成named.root文件
[root@linux named]#dig > named.root   //或下载一个named.root
建立test.com正向解析文件
[root@linux named]#vi test.zone

$ttl    1D
@               IN SOA  test.com.  root.test.com. (

                                      1053891162
                                       3H
                                       15M
                                       1W
                                       1D )

                       IN NS          test.com.
                       IN MX    5    test.com.
www                IN A          172.28.102.28

ftp                IN A          172.28.102.28

建立test.com反向解析文件
[root@linux named]#vi test.local
$TTL 86400
@ IN SOA test.com. root.test.com.(
20031001;
7200;
3600;
43200;
86400);
@ IN NS test.com. 
28 IN PTR dns.test.com.

配置named.conf加如以下代码

[root@linux etc]# vi named.conf

options {
directory "/var/named"; #named区文件目录
pid-file "named.pid"; #进程id文件名
};
controls {
       inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
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 "102.28.172.in-addr.arpa" IN {
       type master;
       file "test.local";
       allow-update { none; };
};



现在配置完了可以启动BIND了

/usr/local/named/sbin/named -c /usr/local/named/etc/named.conf &

只要显示
runing表示运行成功
测试
[root@linux etc]# host

102.28.172.in-addr.arpa domain name pointer dns.test.com.
如上显示表示反向解析正常
[root@linux etc]# ping
PING (172.28.102.28) 56(84) bytes of data.
如上显示表示正向解析正常
配置完成。
