DNS服務(wù)器的架設(shè)實驗環(huán)境：AS4最小化安裝實驗?zāi)繕?biāo)：架設(shè)DNS服務(wù)器編輯： crazylinux 2007.03.22聯(lián)系方式： 大家好！這次我們來學(xué)習(xí)Linux系統(tǒng)中的DNS服務(wù)器的配置。首先我們需要安裝bind軟件，它位于AS4的第四章光盤中，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 # 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我們架設(shè)DNS服務(wù)器需要這些軟件，實例情況：主域名服務(wù)器的地址是 ,從域名服務(wù)器的地址是 winxpIP地址是74在主域名服務(wù)器中添加域名區(qū)域下面我們就來架設(shè)主域名服務(wù)器1，軟件安裝完后我們修改配置文件rootlocalhost # vi /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 * to talk to, you might need to uncomment the query-source * directive below.
