【中文标题】NGINX 缓存 phpmyadmin – 图片未加载

【英文标题】：NGINX caching phpmyadmin – images not loading

【问题描述】：

我有一个 nginx 服务器，我为我的 laravel 网站启用了缓存。我在服务器上也有 phpmyadmin。由于我启用了缓存，所以当我查看它时，来自 phpmyadmin 的图像都没有返回。下面，请找到服务器代码。提前感谢您的帮助。

/phpmyadmin/themes/dot.gif 404（未找到）

【参考方案1】：

在 Nginx 中，正则表达式匹配优于前缀匹配。所以这个指令被认为更适合任何以 gif 结尾的东西

location ~* \.(jpg|jpeg|png|gif|ico)$ expires 30d;

比这个

location /phpmyadmin

所以你的图片都被顶部位置指令处理，即使是开始 /phpmyadmin 的那些，第一个指令与你的 phpmyadmin 位置有不同的根目录，所以 Nginx 找不到那里的文件

【讨论】：

好的 - 这是处理顺序问题吗？有没有办法排除 phpmyadmin 目录不被该语句处理？

如果你把它放在 location 块之上并将它更改为^~ /phpmyadmin 那么 Nginx 将不会处理匹配这个前缀的请求的正则表达式指令
