实验要求：在一台主机上搭建2个网站服务
www.aaa.com
www.bbb.com
实现基于域名的虚拟主机
实现基于IP的虚拟主机
实现基于端口的虚拟主机
一.创建实验环境
1.实现通过域名访问站点需要DNS的解析，可修改DNS数据库文件记录将2个站点IP都指向本机，
也可通过修改/etc/hosts文件来简单实现
# vim /etc/hosts
www.aaa.com 192.168.100.10
www.bbb.com 192.168.100.10
2.创建网站存放目录及测试页
# mkdir -p /data/web/{aaa,bbb}
# echo "<h1>www.aaa.com</h1>" /data/web/aaa/index.html
# echo "<h1>www.bbb.com</h1>" /data/web/bbb/index.html
3.安装软件包
# yum -y install httpd
二.搭建基于域名虚拟主机
1.修改主配置文件
# cd /etc/httpd/conf.d/
# vim vhost.conf
NameVirtualHost 192.168.100.10:80
<VirtualHost 192.168.100.10:80>
DocumentRoot /data/web/aaa
ServerName www.aaa.com
ErrorLog logs/www.aaa.com-error_log
CustomLog logs/www.aaa.com-access_log common
</VirtualHost>
<VirtualHost 192.168.100.10:80>
DocumentRoot /data/web/bbb
ServerName www.bbb.com
ErrorLog logs/www.bbb.com-error_log
CustomLog logs/www.bbb.com-access_log common
</VirtualHost>
2.启动服务
# service httpd start
# chkconfig httpd on
3.浏览器测试
http://www.aaa.com
http://www.bbb.com
三.搭建基于IP的虚拟主机
1.修改主配置文件
# ifconfig eth0:0 192.168.100.20 //设置另一个IP
# vim /etc/httpd/conf.d/vhost.conf
#NameVirtualHost *:80 //不需要这行
<VirtualHost 192.168.10.10:80>
DocumentRoot /data/web/aaa
ServerName 192.168.100.10
ErrorLog logs/192.168.100.10-error_log
CustomLog logs/192.168.100.10-access_log common
</VirtualHost>
<VirtualHost 192.168.100.20:80>
DocumentRoot /data/web/bbb
ServerName 192.168.100.20
ErrorLog logs/192.168.100.20-error_log
CustomLog logs/192.168.100.20-access_log common
</VirtualHost>
2.启动服务
# service httpd restart
# chkconfig httpd on
3.浏览器测试
http://192.168.100.10
http://192.168.100.20
四.搭建基于端口的虚拟主机
1.修改主配置文件
# vim /etc/httpd/conf/httpd.conf
...
134 Listen 80
135 Listen 81
# vim /etc/httpd/conf.d/vhost.conf
#NameVirtualHost *:80
<VirtualHost 192.168.100.10:80>
DocumentRoot /data/web/aaa
ErrorLog logs/192.168.100.10:80-error_log
CustomLog logs/192.168.100.10:80-access_log common
</VirtualHost>
<VirtualHost 192.168.100.10:81>
DocumentRoot /data/web/bbb
ErrorLog logs/192.168.100.10:81-error_log
CustomLog logs/192.168.100.10:81-access_log common
</VirtualHost>
2.启动服务
# service httpd restart
# chkconfig httpd on
3.浏览器测试
http://192.168.100.10:80
http://192.168.100.10:81
