实际测试, 如果同一个端口有多个配置时, 和 ServerName 值无关, 如果请求进来的 ServerName 没有配置到, 按靠前加载的第一条虚拟主机设置配置为准, 不管 ServerName 名字是啥, 也不管里面的访问的域名是否在host中有配置, 都没有关系

Listen 80
<VirtualHost *:80>
        DocumentRoot "D:\code\www"
        FcgidInitialEnv PHPRC "D:/server/web/server/php"
        AddHandler fcgid-script .php
        FcgidWrapper "D:/server/web/server/php/php-cgi.exe" .php
      <Directory "D:\code\www">
          Options FollowSymLinks ExecCGI
          AllowOverride All
          Order allow,deny
          Allow from all
         Require all granted
      </Directory>
    ProxyPass /hb/ http://192.168.56.103:9501/
    ProxyPass /80/ http://127.0.0.1:81/
</VirtualHost>

业务场景说明

  1. 比如扒人家的站点, 图片相对地址一个个的扒很不方便, 通过301重定向简单配置一下可以实现当图片没有下载到对应的相对位置时, 会自动重定向下载
  2. vue容器环境下, 每次发布新版本时, 保证缓存老代码的用户访问不会出现404js文件, 可以考虑一台机器用于存放这部分的js文件

保存到文件 auto_download_image.php

在静态文件目录下保存一个 .htaccess 文件

    <IfModule mod_negotiation.c>
        Options -MultiViews -Indexes
    </IfModule>

    RewriteEngine On
