总共有三种方法：通过不同的IP地址
通过不同的域名
通过不同的端口号
(1).通过不同的IP地址实现
例如一台CentOS7有两个IP：192.168.5.101和192.168.5.103
[root@youxi1 conf]# cd /etc/httpd/conf.d/
[root@youxi1 conf.d]# vim test.conf //新建一个配置文件
<VirtualHost 192.168.5.101:9988> //IP和端口ServerAdmin webmaster@dummy-host.example.comDocumentRoot /var/www/html/ //指向的路径ServerName dummy-host.example.comErrorLog logs/dummy-host.example.com-error_logCustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
<VirtualHost 192.168.5.103:9988> //IP和端口ServerAdmin webmaster@dummy-host.example.comDocumentRoot /var/www/html/test/ //指向的路径ServerName dummy-host.example.comErrorLog logs/dummy-host.example.com-error_logCustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
[root@youxi1 conf.d]# vim /var/www/html/index.php
/var/www/html/index.html
[root@youxi1 conf.d]# vim /var/www/html/test/index.html
/var/www/html/test/index.html
[root@youxi1 conf.d]# systemctl restart httpd.service实验结果：
(2).通过不同的域名实现
首先需要在域名管理系统中将两个域名解析的IP地址指向同一个。
[root@youxi1 conf.d]# vim test.conf //新建一个配置文件
<VirtualHost *:9988>ServerAdmin webmaster@dummy-host.example.comDocumentRoot /var/www/html/ //指向的路径ServerName www.youxi1.comErrorLog logs/www.youxi1.com-error_logCustomLog logs/www.youxi1.com-access_log common
</VirtualHost>
<VirtualHost *:9988>ServerAdmin webmaster@dummy-host.example.comDocumentRoot /var/www/html/test/ //指向的路径ServerName test.youxi1.comErrorLog logs/test.youxi1.com-error_logCustomLog logs/test.youxi1.com-access_log common
</VirtualHost>
[root@youxi1 conf.d]# systemctl restart httpd.service
由于我没有DNS服务器，所以修改hosts文件
[root@youxi1 conf.d]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.5.101 www.youxi1.com
192.168.5.101 test.youxi1.com
Windows修改在C:\Windows\System32\drivers\etc目录下的hosts文件
192.168.5.101 www.youxi1.com
192.168.5.101 test.youxi1.com
实验结果：
(3).通过不同的端口号实现
修改/etc/httpd/conf/https.conf文件，添加监听端口
Listen 9988
Listen 9989
接着再修改新建的test.conf
[root@youxi1 conf.d]# vim test.conf
<VirtualHost *:9988>ServerAdmin webmaster@dummy-host.example.comDocumentRoot /var/www/html/ServerName www.youxi1.comErrorLog logs/www.youxi1.com-error_logCustomLog logs/www.youxi1.com-access_log common
</VirtualHost>
<VirtualHost *:9989>ServerAdmin webmaster@dummy-host.example.comDocumentRoot /var/www/html/test/ServerName www.youxi1.comErrorLog logs/www.youxi1.com-error_logCustomLog logs/www.youxi1.com-access_log common
</VirtualHost>
[root@youxi1 conf.d]# systemctl restart httpd.service
[root@youxi1 conf.d]# vim /etc/hosts
192.168.5.101 www.youxi1.com
Windows修改在C:\Windows\System32\drivers\etc目录下的hosts文件
192.168.5.101 www.youxi1.com
实验结果：
