假设要配置基于8000端口的虚拟主机

修改httpd.conf

# vim /etc/httpd/conf/httpd.conf

找到Listen 80，在下面添加Listen 8000（提示：在防火墙中打开8000端口）

<VirtualHost *:8000> 
    ServerAdmin webmaster@123admin.com
    DocumentRoot /var/www/html/123admin
    ErrorLog logs/123admin.com-error_log
    CustomLog logs/123admin.com-access_log combined
    DirectoryIndex index.html index.htm index.php

    <Directory "/var/www/html/123admin">
        Options -Indexes FollowSymLinks
        AllowOverride all
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

重启apache

# service httpd reload
