PHP files are DOWNLOADING instead of EXECUTING on Nginx - php

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'

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.
