PHP文件正在下载，而不是在Nginx上执行

我有一个简单的docker compose配置，使用php fpm和nginx

看起来Nginx无法将php文件传递给phpfpm，这会导致下载php文件而不是执行

它可以处理html文件（localhost:8080/readme.html）

当我转到localhost（）的根目录时，总是出现403禁止的错误

请帮忙

docker-compose.yml

version: '3'

services:

    nginx:
        image: nginx:alpine
        container_name: nginx
        restart: always
        volumes:
            - './etc/nginx/nginx.conf:/etc/nginx/nginx.conf'
            - './var/log:/var/log'
            - './web:/usr/share/nginx/html'
        ports:
            - 8080:80
            - 443:443
        depends_on:

    php:

问题是php fpm（

/var/www/html

）和nginx（

/usr/share/nginx/html

）的根文件夹不同，但您可以在这一行中将根文件夹的名称从nginx传递给php fpm：

fastcgi\u参数脚本\文件名$document\u root$fastcgi\u脚本\名称

因此，php fpm在错误的文件夹中查找，无法执行php文件

尝试使用
/var/www/html
作为nginx的根目录（在nginx配置和docker comnpose文件中更改它），php fpm应该能够找到并执行php文件。
