How to set up nginx upstream with php on ubuntu?

Question

On ubuntu 18.04, I have nginx running

upstream vault {
  server 127.0.0.1:8001;
}

server {
    listen 80;
    server_name vault.shopshop.space;

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log debug;

    location ~ \.php$ {
        fastcgi_pass vault;
    }
}

The idea is that when I hit vault.shopshop.space, it should hit a simple php backgroud serivce listening 8001

This php background service is from here: https://www.slimframework.com/docs/v3/tutorial/first-app.html

<?php
use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;

require '../vendor/autoload.php';

$app = new \Slim\App;
$app->get('/hello/{name}', function (Request $request, Response $response, array $args) {
    $name = $args['name'];
    $response->getBody()->write("Hello, $name");

    return $response;
});
$app->run();

I run this php -S localhost:8001, I can curl in my ubuntu server.

curl http://localhost:8001/hi/bla

will output hello, bla

run netstat -npl

the simple php service is listening 8001 in ip4 and ip6

ufw firewall

To                         Action      From

443/tcp (v6)               ALLOW       Anywhere (v6)             
8001 (v6)                  ALLOW       Anywhere (v6)

firewall can listen 8001

www.conf, only listen 8001

/etc/php/5.6/fpm/pool.d/www.conf

;listen = /run/php/php5.6-fpm.sock
listen = 8001

The problem:

http://vault.shopshop.space/hi/bla, 404

http://vault.shopshop.space, default nginx page

I expect hello bla

Here is configuration example for nginx + php-fpm in documentation.

You haven't in your configuration:

root
fastcgi params
etc

Here is example with upstream:

upstream vault {
    server 127.0.0.1:8001;
}

server {
    listen 80;
    server_name vault.shopshop.space;

    error_log /var/log/nginx/vault.shopshop.space_error.log;
    access_log /var/log/nginx/vault.shopshop.space_access.log;

    root /path/to/public;
    index index.php;

    location / {
        try_files $uri /index.php$is_args$args;
     }

    location ~ \.php {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param SCRIPT_NAME $fastcgi_script_name;
        fastcgi_index index.php;
        fastcgi_pass vault;
    }
}

You should fix path to public dir in root string.

Everything that @mindfl said, plus you have no catch all location block. Your only location block is this, which defines a regex match for requests ending with .php

location ~ \.php$ {
    fastcgi_pass vault;
}

http://vault.shopshop.space/hi/bla doesn't end with .php, and as you have no index or try_files directives then that request is never going to be processed by that location block.

The config posted by @mindfl should be a good starting point for you.
