RedHat9.0下的DNS和虚拟主机的配置
配置几个简单的虚拟主机，DNS 服务器IP为169.254.1.189例我公司的域名为:stcore.com.我想配置以下几个服务器为：
ftp.stcore.com,mail.stcore.com,kuanping.stcore.com,soft.stcore.com,
xiaoshou.zzvcom.com,cpzz.zzvcom.com,net.zzvcom.com,yanfa.zzvcom.com.
先安装RPM域名解析软件named,再下载apache.tar.gz
#tar –zxvf apache.tar.gz
#cd apache
#./configure –prefix=/usr/local/apache
#make;make install;make clean
#vi /usr/local/apache/conf/httpd.conf
ServerName 169.254.1.189
NameVirtualHost 169.254.1.189
<VirtualHost 169.254.1.189>
ServerName ftp.stcore.com
DocumentRoot /www/ftp
TransferLog logs/ftp_access_log
</VirtualHost>
<VirtualHost 169.254.1.189>
ServerName mail.zzvcom.com
DocumentRoot /www/mail
TransferLog logs/mail_access_log
</VirtualHost>
<VirtualHost 169.254.1.189>
ServerName kuanping.zzvcom.com
DocumentRoot /www/kuanping
TransferLog logs/kuanping_access_log
</VirtualHost>
<VirtualHost 169.254.1.189>
ServerName soft.zzvcom.com
DocumentRoot /www/soft
TransferLog logs/soft_access_log
</VirtualHost>
<VirtualHost 169.254.1.189>
ServerName xiaoshou.zzvcom.com
DocumentRoot /www/xiaoshou
TransferLog logs/xiaoshou_access_log
</VirtualHost>
<VirtualHost 169.254.1.189>
ServerName cpzz.zzvcom.com
DocumentRoot /www/cpzz
TransferLog logs/cpzz_access_log
</VirtualHost>
<VirtualHost 169.254.1.189>
ServerName net.zzvcom.com
DocumentRoot /www/net
TransferLog logs/net_access_log
</VirtualHost>
<VirtualHost 169.254.1.189>
ServerName yanfa.zzvcom.com
DocumentRoot /www/yanfa
TransferLog logs/yanfa_access_log
</VirtualHost>
#mkdir /www
#cd /www
#mkdir ftp mail soft xiaoshou net yanfa cpzz kuanping
分别在/www/ftp /www/mail /www/soft /www/xiaoshou /www/net
/www/yanfa /www/kuanping /www/cpzz目录下放一个各自的主页（index.html），并将其属性设为755。
#/usr/local/apache/bin/apachectl configtest
#/usr/local/apache/bin/httpd -S
若一切都OK，就可以运行以下命令（启动apache）
#/usr/local/apache/bin/apachectl start
#vi /etc/named.conf
在尾部加上如下几行:
zone "1.254.169.in-addr.arpa" in {
type master;
file "db.1.254.169";
allow-update { none; };
};
zone "stcore.com" {
type master;
file "stcore.coms";
allow-update { none; };
};
#vi /var/named/db.1.254.169
@ IN SOA localhost. root.localhost. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry

86400 ) ; Minimum
IN NS localhost.
1 IN PTR localhost.
189 IN PTR ftp.stcore.com
#vi /var/named/zzvcom.coms
@ IN SOA dns.stcore.com. root.stcore.com. (

86400 ) ; Minimum TTL of 1 day
@ IN NS dns.zzvcom.com.
localhost IN A 127.0.0.1
ftp IN A 169.254.1.189
mail IN CNAME ftp
kuanping IN CNAME ftp
xiaoshou IN CNAME ftp
net IN CNAME ftp
soft IN CNAME ftp
yanfa IN CNAME ftp
cpzz IN CNAME ftp
#vi /etc/resolv.conf
domain zzvcom.com
nameserver 169.254.1.189
#/etc/rc.d/init.d/named start
用nslookup检验一下DNS的正确性。在我们客户端(WINDOWS下)设置DNS为169.254.1.189（只要这一个，因为我们的DNS服务器还不是一个公网IP，且没有申请为DNS服务器）。在IE里打开这个网址 ftp.stcore.com soft.stcore.com 若正确，所有实验就成功了。
