linux DNS服务配置 [笔记]

一，首先安装bind

 [root@linux ~]# rpm -qa | grep bindbind-utils-9.2.4-16.EL4 <==这个是用户端搜寻主机名称的相关指令bind-9.2.4-16.EL4 <==这个才是 DNS 服务器主程序bind-chroot-9.2.4-16.EL4 <==将 bind 主程式关在家里面！

 

二，DNS主机所设置档案

1. /etc/named.conf
2. /var/named/named.root
3. /var/named/named.localhost
4. /var/named/named.127.0.0
5. /var/named/named.正解档案
6. /var/named/named.反解档案

三，代码

    1. 创建named.conf

   [root@localhost ~]# vi /var/named/chroot/etc/named.confoptions { directory "/var/named"; forwarders { 168.95.1.1; }; pid-file "/var/run/named/named.pid"; allow-query { any; }; allow-transfer { any; }; };zone "." { type hint; file "named.root"; };zone "localhost" { type master; file "named.localhost"; };zone "0.0.127.in-addr.arpa" { type master; file "named.127.0.0"; };zone "vbird.org" { type master; file "named.vbird.org"; }; zone "1.168.192.in-addr.arpa" { type master; file "named.192.168.1"; };

 

 

 

 2.获得named.root (这个档案不要去改)

 [root@test root]# ftp rs.internic.net Connected to rs.internic.net. Name (rs.internic.net:root): anonymous 331 Guest login ok, send your complete e-mail address as password. Password: <==your password 230 User ftp logged in. Access restrictions apply. Remote system type is UNIX. Using binary mode to transfer files. ftp> cd domain ftp> get named.root ftp> bye

 

 

 3.   创建named.localhost

 [root@localhost named]# cat named.localhost $TTL 600 @ IN SOA localhost. root.localhost. ( 2002120601 28800 14400 720000 86400 ) @ IN NS localhost.localhost. IN A 127.0.0.1

 

4.  创建named.127.0.0

[root@localhost named]# cat /var/named/chroot/var/named/named.127.0.0 $TTL 600 ; This is about DNS server's settings @ IN SOA localhost. root.localhost. ( 2002120601 ; Serial 28800 ; Refresh 14400 ; Retry 720000 ; Expire 86400 ) ; Minimum ; The server's infomations @ IN NS localhost. 1 IN PTR localhost.

 

 

5. 创建named.vbird.org  (设定 domain name 的正解)

 [root@localhost named]# cat /var/named/chroot/var/named/named.vbird.org $TTL 600 @ IN SOA mdk90.vbird.org. root.mdk90.vbird.org. ( 2002120601 ; Serial 28800 ; Refresh 14400 ; Retry 720000 ; Expire 86400 ) ; minimum @ IN NS mdk90.vbird.org.@ IN MX 10 mdk90.vbird.org.mdk90 IN A 192.168.1.2 mdk90 IN TXT "The testing DNS server"phorum.mdk90 IN CNAME mdk90www.mdk90 IN CNAME mdk90.vbird.org. win2k IN A 192.168.1.100 win2k IN HINFO "AMD-K6-III""Windows 2000" winxp IN A 192.168.1.200

 

 

6.创建named.192.168.1 (设定 domain name 的反解)

[root@localhost named]# cat /var/named/chroot/var/named/named.192.168.1 $TTL 600 @ IN SOA mdk90.vbird.org. root.mdk90.vbird.org. ( 2002120601 ; Serial 28800 ; Refresh 14400 ; Retry 720000 ; Expire 86400 ) ; minimum @ IN NS mdk90.vbird.org. 2 IN PTR mdk90.vbird.org. ; The following is about other hosts 100 IN PTR win2k.vbird.org. 200 IN PTR winxp.vbird.org.

 

 

四，启动 named 与 port 及讯息确认：

 

  1. 开始启动！ [root@test root]# /etc/rc.d/init.d/named start Starting named: [ OK ] 2. 关于 port 观察： [root@test root]# netstat -tuln | grep 53 tcp 0 0 192.168.1.2:53 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:53 0.0.0.0:* LISTEN udp 0 0 192.168.1.2:53 0.0.0.0:* udp 0 0 127.0.0.1:53 0.0.0.0:*3. 关于讯息的内容！ Dec 8 23:27:39 test named[8106]: starting BIND 9.2.1 -u named Dec 8 23:27:39 test named[8106]: using 1 CPU Dec 8 23:27:39 test named: named startup succeeded Dec 8 23:27:40 test named[8111]: loading configuration from '/etc/named.conf' Dec 8 23:27:40 test named[8111]: no IPv6 interfaces found Dec 8 23:27:40 test named[8111]: listening on IPv4 interface lo, 127.0.0.1#53 Dec 8 23:27:40 test named[8111]: listening on IPv4 interface eth0, 192.168.1.2#53 Dec 8 23:27:40 test named[8111]: couldn't add command channel 127.0.0.1#953: not found Dec 8 23:27:40 test named[8111]: zone 0.0.127.in-addr.arpa/IN: loaded serial 2002080601 Dec 8 23:27:40 test named[8111]: zone 1.168.192.in-addr.arpa/IN: loaded serial 2002120601 Dec 8 23:27:40 test named[8111]: zone localhost/IN: loaded serial 2002080601 Dec 8 23:27:40 test named[8111]: zone vbird.org/IN: loaded serial 2002120601 Dec 8 23:27:40 test named[8111]: running
