Fedora Core5 NFS服务器搭建过程介绍

域名服务器搭建主要涉及的文件主要有:

(1)/etc/named.conf,此文件一般是个软链接;

(2)/etc/hosts(非必须)

(3)/etc/host.conf (一般不需要修改,有 order hosts,bind即可)

(4)/var/named/*

此文档只是一个NFS的初级搭建工程,就是能够运行的级别,没有什么高级设置,目的是快速入门。

当然首先要查查系统是否已经安装了DNS的软件工具(BIND),如没有那只有拿来光盘重新安装或者到官方网站下载源码包编译安装,此处是采用系统自带的BIND;

接下来就是进行相关文件的配置了;

相关的配置文件均在/var/named目录下,主要配置为/var/named/chroot/etc/named.conf,域解析文件放在/var/named/chroot/var/named目录下;

此次的目的就是搭建一个简单的DNS服务器,并且设置DNS服务器的主机名;

具体步骤如下:

1、配置named.conf文件

/var/named/chroot/etc/named.conf主要添加的配置内容如下:

zone "osservers.com" IN { type master; file "osserver.com.zone"; allow-update { none; };};zone "67.20.172.in-addr.arpa" IN { type master; file "zone.osserver.com"; allow-update { none; };};

2、配置相应的解析文件

两个解析文件如下:(/var/named/chroot/var/named)

/var/named/chroot/var/named /osserver.com.zone文件:

$TTL 86400@ IN SOA dns.osservers.com. root.osservers.com. ( 42 ; serial (d. adams) 3H ; refresh 15M ; retry 1W ; expiry 1D ) ; minimum IN NS dns.osservers.com. IN NS 172.20.67.203dns.osservers.com. IN A 172.20.67.203www IN A 172.20.67.203/var/named/chroot/var/named /zone.osserver.com文件:$TTL 86400@ IN SOA dns.osservers.com. root.osservers.com. ( 1997022700 ; Serial 28800 ; Refresh 14400 ; Retry 3600000 ; Expire 86400 ) ; Minimum IN NS dns.osservers.com.203 IN PTR

3、重新启动服务

/etc/init.d/named restart

4、测试部分

(1)设置域名文件/etc/resolve.conf,将nameserver 172.20.67.203加入;

(2)采用nslookup/host/测试:

[root@samba named]# nslookup> 172.20.67.203Server: 172.20.67.203Address: 172.20.67.203#53203.67.20.172.in-addr.arpa name = > : 172.20.67.203Address: 172.20.67.203#53Name: : 172.20.67.203> [root@samba named]# host has address 172.20.67.203[root@samba named]# host 172.20.67.203203.67.20.172.in-addr.arpa domain name pointer [root@samba named]#[root@samba named]# dig ; <<>> DiG 9.3.2 <<>> ;; global options: printcmd;; Got answer:;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 3294;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 1;; QUESTION SECTION:; IN A;; ANSWER SECTION: 86400 IN A 172.20.67.203;; AUTHORITY SECTION:osservers.com. 86400 IN NS 172.20.67.203.osservers.com. 86400 IN NS dns.osservers.com.;; ADDITIONAL SECTION:dns.osservers.com. 86400 IN A 172.20.67.203;; Query time: 1 msec;; SERVER: 172.20.67.203#53(172.20.67.203);; WHEN: Wed Apr 25 13:39:31 2007;; MSG SIZE rcvd: 112

OK,搞定!

简单的DNS服务器完成了。
