PHP文件正在下载而不是在Nginx上执行

Question

I have a simple docker-compose config with php-fpm and nginx.

It looks like Nginx can't pass the php file to php-fpm which results in download of php files instead of execution.

It works with html files.(localhost:8080/readme.html).

I always get a 403 Forbidden error when I go to root of localhost( http://localhost/ ).

Please help.

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

    php:
        image: php:fpm-alpine
        container_name: php
        restart: always
        volumes:
            - "./web:/var/www/html"
            - './var/log:/var/log'

Answer 1

The problem is that the root folder for php-fpm ( /var/www/html ) and nginx ( /usr/share/nginx/html ) are different but you pass the name of the root folder from nginx to php-fpm in this line: fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

Because of that, php-fpm looks in the wrong folder and can't execute the PHP file.

Try using /var/www/html as the root for nginx (change it in the nginx config and the docker-comnpose file) and php-fpm should be able to find and execute the PHP files.
