1、DNS服务器的架设实验环境：AS4最小化安装实验目标：架设DNS服务器编辑： crazylinux 2007.03.22联系方式：http:/ 大家好！这次我们来学习Linux系统中的DNS服务器的配置。首先我们需要安装bind软件，它位于AS4的第四章光盘中，rootlocalhost # rpm -ivh /media/cdrom/RedHat/RPMS/bind-9.2.4-2.i386.rpmrootlocalhost # rpm -ivh /media/cdrom/RedHat/RPMS/caching-nameserver-7.3-3.noarch.rpmrootlocalhost
2、 # rpm -qa | grep bindbind-utils-9.2.4-2bind-9.2.4-2bind-libs-9.2.4-2ypbind-1.17.2-3rootlocalhost # rpm -qa | grep cachingcaching-nameserver-7.3-3我们架设DNS服务器需要这些软件，实例情况：主域名服务器的地址是192.168.1.2 ,从域名服务器的地址是192.168.1.3 winxpIP地址是192.168.1.174在主域名服务器中添加域名区域下面我们就来架设主域名服务器1，软件安装完后我们修改配置文件rootlocalhost # vi /
3、etc/named.conf修改完后的named.conf如下：rootlocalhost # cat /etc/named.conf/ named.conf for Red Hat caching-nameserver /options directory /var/named; dump-file /var/named/data/cache_dump.db; statistics-file /var/named/data/named_stats.txt; /* * If there is a firewall between you and nameservers you want * t
4、o talk to, you might need to uncomment the query-source * directive below. Previous versions of BIND always asked * questions using port 53, but BIND 8.1 uses an unprivileged * port by default. */ / query-source address * port 53;/ / a caching only nameserver config/ controls inet 127.0.0.1 allow lo

7、e 0.in-addr.arpa IN type master; file named.zero; allow-update none; ;include /etc/rndc.key;2建立正向和反向区域文件 rootlocalhost named# cd /var/named/rootlocalhost named# cp localhost.zone .zone 把localhost的摸版cp后修改嘿嘿修改完后的.zone的文件如下rootlocalhost named# cat .zone $TTL 86400 IN SOA . . ( 42 ; serial (d. adams) 3H

IN MX 5 .rootlocalhost named# cp .zone 192.168.1.rev 把修改完后的.zone cp一份作为反向配置文件，修改后如下rootlocalhost named# cat 192.168.1.rev $TTL 86400 IN SOA . . ( 42 ; seri
