Linux-DNS服务器的IP地址是192.168.2.98
需要配置的DNS地址是192.168.2.212，这个IP地址必须没有人使用，不然安装grid会报错
1、安装以下rpm包
bind-9.3.6-4.P1.el5.x86_64.rpm
bind-chroot-9.3.6-4.P1.el5.x86_64.rpm
caching-nameserver-9.3.6-4.P1.el5.x86_64.rpm
2、复制named.caching-nameserver.conf文件为named.conf，并修改named.conf文件
[root@bjgtj1 opt]# cd /var/named/chroot/etc/
[root@bjgtj1 etc] cp -p named.caching-nameserver.conf named.conf (-p参数会将权限也复制过来)
[root@bjgtj1 etc] vi named.conf
将以下5处的内容修改成any
listen-on port 53 { any; };
allow-query { any; };
allow-query-cache { any; };
match-clients { any; };
match-destinations { any; };
4、复制模板文件成数据文件
[root@bjgtj1 etc]# cd /var/named/chroot/var/named/
[root@bjgtj1 named]# cp -p localhost.zone rac.linuxidc.zone
[root@bjgtj1 named]# cp -p named.local rac.linuxidc.local
[root@bjgtj1 named]# vi rac.linuxidc.zone
