Redhat9.0 下DNS配置笔记
作者:andrew_ai(小艾)
环境:企业局域网
系统:Redhat9.0,并设有三个段的IP(四网卡),分别是192.168.2.7 ; 192.168.6.7 ; 192.168.10.7
需配置文件:1./etc/named.conf(系统自带)
2./var/named/2.168.192.file(自建)
3./var/named/6.168.192.file(自建)
4./var/named/10.168.192.file(自建)
5./var/named/mytest.com
6./etc/host.conf
跟很多菜菜们一样,我配置DNS也是一波三折,人都搞晕掉了,查了很多资料也问了很多人,但得到的结果
始终是那句:Can't find ...。一怒之下,把自带的BIND干掉,重新安装了与之相关的所有套件再配置。嘿
嘿...搞定!!!,后来怀疑可能是套件有问题或者是并没有装全(未经考证)。小弟我谨以此文章感谢所有无私网
友的奉献精神,并希望它能带给正处困境中的Linuxer一点帮助或启示。
一、安装BIND:
1.下载如下套件:bind-devel-9.2.1-16.i386.rpm
bind-utils-9.2.1-16.i386.rpm
bind-9.2.1-16.i386.rpm
caching-nameserver-7.2-7.noarch.rpm
2.如有自带BIND先除去。在rpm -e bind时可能出现错误提示:
[root@andrew root]# rpm -e bind
error: Failed dependencies:
bind = 9.2.1 is needed by (installed) bind-devel-9.2.1-16
bind is needed by (installed) caching-nameserver-7.2-7
bind = 9.1.3-0.rc2.3 is needed by (installed) caching-nameserver-7.2-7
那就得先将提示的几个套件先移除。
3.安装BIND及相关。rpm -ivh xxx.rpm即可。
当然,我把自带BIND移除也是被逼无路,迫不得已的之行为,对于高手们来说可能完全不必要。
二、具体配置及说明:
###named.conf
// generated by named-bootconf.pl
options {
directory "/var/named"; ##指定DNS文件所在的目录
/*
* If there is a firewall between you and nameservers you want
* to 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;
};
