第一步：配置Apache 的 httpd.conf

#Listen 0.0.0.0:80
Listen 80
Listen 81

第二步：开启虚拟站点

所属文件：httpd.conf

#Virtual hosts
#Include conf/extra/httpd-vhosts.conf
修改为

# Virtual hosts

Include conf/extra/httpd-vhosts.conf

第三步：配置conf/extra/httpd-vhosts.conf

<VirtualHost *:81>
 ServerAdmin webmaster@dummy-host.localhost
 DocumentRoot "/data/wwwroot"
 ServerName 81
 ErrorLog "logs/dummy-host.localhost-error.log"
 CustomLog "logs/dummy-host.localhost-access.log" common
 <Directory "/data/wwwroot">
  Options FollowSymLinks
  AllowOverride None
  Require all granted
 </Directory>
</VirtualHost>

如果访问站点出现you don't have permission to access / on this server(Apache Server权限访问问题)

修改httpd.conf:
 
<Directory />
 AllowOverride none
 Require all denied
</Directory>

<Directory />
 AllowOverride none
# Require all denied
</Directory>
