一台 Linux 中网站虚拟主机的完成主要有三种方式：a、根据 ip 地址；b、根据端口号；c、根据域名。一下为完成进程：（本试验的 Linux 虚机系统为 rhel5.6）
1、基于域名的实现：
这种方式需要搭建 dns 域名服务器。
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
IPADDR=192.168.22.133
NETWORK=192.168.22.0
NETMASK=255.255.255.0
BROADCAST=192.168.22.255
HWADDR=00:0C:29:89:05:2E
ONBOOT=yes
# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=httpd.com
# cat /etc/resolv.conf
nameserver 192.168.22.133
search httpd.com
#yum install httpd -y
# vim /etc/httpd/conf/httpd.conf
NameVirtualHost 192.168.22.133:80 #将这一行注释符取消掉，* 号改成 ip 地址
<VirtualHost 192.168.22.133:80> #复制粘贴即可得到以下几行（nyy p)
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot /www/bbs
ServerName bbs.httpd.com
ErrorLog logs/dummy-host.example.com-error_log
CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
<VirtualHost 192.168.22.133:80>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot /www/news
ServerName news.httpd.com
ErrorLog logs/dummy-host.example.com-error_log
CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
#mkdir -p /www/{news,bbs}
#vim /www/news/index.html

#vim /www/bbs/index.html
hello ,this is bbs
#service network restart
#service httpd start
#yum install bind bind-chroot bind-utils caching-nameserver -y
#cd /var/named/chroot/etc
#cp -a named.caching-nameserver.conf named.conf
#vim named.conf
options {
listen-on port 53 {any;};
directory “/var/named”;
dump-file “/var/named/data/cache_dump.db”;
statistics-file “/var/named/data/named_stats.txt”;
allow-query {any;};
allow-query-cache {any;};
};
zone “httpd.com” {
type master;
file “httpd.com.zone”;
};
zone “22.168.192.in-addr.arpa” {
type master;
file “22.168.192.zone”;
};
#cd ../var/named
#touch httpd.com.zone
#touch 22.168.192.zone
#cat localhost.zone > httpd.com.zone
#cat named.local > 22.168.192.zone
#vim httpd.com.zone

#service named start

# host news.httpd.com

# host 192.168.22.133

在 Linux 自带的火狐浏览器测试，如下图：
在另外一台虚拟的 xp 系统上面测试：（此时的 Linux 和 xp 虚机均为桥接方式），如下图
ok，到此为止，Linux 下 http 域名虚拟主机的配置完美结束。
2、基于 ip 地址的实现
#cp ifcfg-eth0 ifcfg-eth0:1
#cp ifcfg-eth0 ifcfg-eth0:2
# cat ifcfg-eth0:1
DEVICE=eth0:1
BOOTPROTO=static
IPADDR=192.168.22.134
NETWORK=192.168.22.0
NETMASK=255.255.255.0
BROADCAST=192.168.22.255
HWADDR=00:0C:29:89:05:2E
ONBOOT=yes
# cat ifcfg-eth0:2
DEVICE=eth0:2
BOOTPROTO=static
IPADDR=192.168.22.135
NETWORK=192.168.22.0
NETMASK=255.255.255.0
BROADCAST=192.168.22.255
HWADDR=00:0C:29:89:05:2E
ONBOOT=yes
#service network restart
#vim /etc/httpd/conf/httpd.conf
<VirtualHost 192.168.22.133:80>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot /www/133
ServerName 192.168.22.133
ErrorLog logs/dummy-host.example.com-error_log
CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
<VirtualHost 192.168.22.134:80>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot /www/134
ServerName 192.168.22.134
ErrorLog logs/dummy-host.example.com-error_log
CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
<VirtualHost 192.168.22.135:80>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot /www/135
ServerName 192.168.22.135
ErrorLog logs/dummy-host.example.com-error_log
CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost> #要把 NameVirtualHost 关掉
#mkdir -p /www/{133,134,135}
# cat /www/133/index.html
hello ,this is 133 page.
# cat /www/134/index.html
hi ,this is 134 index
# cat /www/135/index.html
hey,this is 135 index page
#service httpd restart
到此，打开 Linux 自带的火狐浏览器浏览，如下图所示：
基于 ip 地址的虚拟主机搭建成功。
3、基于端口的实现：
首先要手工配置一个 ip 地址，本实验使用的地址为 192.168.22.133，改地址怎样配置见方式 1 详解。
#vim /etc/httpd/conf/httpd.conf
Listen 80
Listen 8080
Listen 8081 #在 Listen 下面添加下面两行
。。。。
<VirtualHost 192.168.22.133:80>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot /www/80
ServerName 192.168.22.133
ErrorLog logs/dummy-host.example.com-error_log
CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
<VirtualHost 192.168.22.133:8080>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot /www/8080
ServerName 192.168.22.133
ErrorLog logs/dummy-host.example.com-error_log
CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
<VirtualHost 192.168.22.133:8081>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot /www/8081
ServerName 192.168.22.133
ErrorLog logs/dummy-host.example.com-error_log
CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
#mkdir -p /www/{80,8080,8081}
# cat /www/80/index.html
this is port 80 page
# cat /www/8080/index.html
this is port 8080 test page
# cat /www/8081/index.html
hello, this is port 8081 page
#service httpd restart
到此用 Linux 自带的火狐浏览器测试一下，如下图所示：
到此，根据端口方法的方式装备成功。
到此为止，Linux 网站虚拟主机的三种装备方法装备结束。
