<VirtualHost *:80>

    DocumentRoot "E:\PHPER\btc_biying_www\public"

    ServerName by.cn

    ErrorLog "logs/dummy-host2.example.com-error.log"

    CustomLog "logs/dummy-host2.example.com-access.log" common

    <Directory "E:\PHPER\btc_biying_www\public">

    </Directory>

</VirtualHost>

1、查找httpd.conf中查找deny from all 替换为 Allow from all

2、检查Directory路径和DocumentRoot是否一致

3、Options参数Indexes FollowSymLinks Includes ExecCGI（如果是phpStudy环境都加上）

4、如果是Linux环境注意权限问题
