Nginx not showing index.php - php

Question

So guys i have runned a docker-compose who contain instructions to up a container with nginx another with php and another with mysql, but when i try to acess nginx he gives me this error:
403 Forbidden
I think that could be something wrong in his config, here his config file:
server {
listen 80;
index index.php index.html;
server_name localhost;
error_log /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;
root /code;
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass php:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
}
For the case here is the docker-compose file:
version: '2'
services:
web:
image: nginx:latest
ports:
- "80:80"
volumes:
- ./code/public_html:/code
- ./site.conf:/etc/nginx/conf.d/default.conf
links:
- php
php:
image: php7-custom-conf
volumes:
- ./code/public_html:/code
links:
- db
db:
image: mysql:5.7
volumes:
- "./.data/db:/var/lib/mysql"
restart: always
ports:
- "3306:3306"
environment:
MYSQL_ROOT_PASSWORD: dbrootpass
MYSQL_DATABASE: dbname
MYSQL_USER: dbuser
MYSQL_PASSWORD: dbpass
Any help is appreciated, anyway thanks for the attention.
Sorry for any errors not a english speaker here ;)

Answer 1

Your configuration is fine. But it looks like nginx can't access your code/public_html folder. Make sure it's executable for all users, e. g. chmod 0755 ./code/public_html. Another solution is to change the user and/or group of the nginx process to match the owner of the public_html folder.

Answer 2

The problem is in your location ~ \.php$.
Try replacing it with:
location ~ \.php$ {
proxy_pass http://php:9000;
}
I retest it. If you connect to http://localhost/ it'll return a 403 because the rights are wrong (thanks to #dizeee) but if you try to connect to http://localhost/index.php it returns a 404 because the proxy_pass is not defined.
