File Not Found when running PHP with Nginx

Recently I installed the latest version of Nginx and looks like I'm having hard time running PHP with it.

Here is the configuration file I'm using for the domain:

server {
listen       80;
server_name  localhost;

location / {
    root   /usr/share/nginx/html;
    index  index.php;
}

error_page   500 502 503 504  /50x.html;
location = /50x.html {
    root   /usr/share/nginx/html;
}

location ~ \.php$ {
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    include        fastcgi_params;
}

}

Here is the error I'm getting on the error log file:

FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream

Solution 1:

Try another *fastcgi_param* something like

fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;

Solution 2:

I had the "file not found" problem, so I moved the "root" definition up into the "server" bracket to provide a default value for all the locations. You can always override this by giving any location it's own root.

server {
    root /usr/share/nginx/www;
    location / {
            #root /usr/share/nginx/www;
    }

    location ~ \.php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            include fastcgi_params;
    }
}

Alternatively, I could have defined root in both my locations.

Solution 3:

Probably it's too late to answer but a couple things since this is a really annoying error. Following solution worked on Mac OS X Yosemite.

  1. It's the best if you have

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

  1. The include with fast cgi params should go above that line.

  2. All your directories down to the PHP file you're executing (including that file too) should have a+x permissions, e.g.

sudo chmod a+x /Users/
sudo chmod a+x /Users/oleg/
sudo chmod a+x /Users/oleg/www/
sudo chmod a+x /Users/oleg/www/a.php

Solution 4:

I had been having the same issues, And during my tests, I have faced both problems:

1º: "File not found"

and

2º: 404 Error page

And I found out that, in my case:

I had to mount volumes for my public folders both on the Nginx volumes and the PHP volumes.

If it's mounted in Nginx and is not mounted in PHP, it will give: "File not found"

Examples (Will show "File not found error"):


services:
  php-fpm:
    build:
      context: ./docker/php-fpm
  nginx:
    build:
      context: ./docker/nginx
    volumes:
        #Nginx Global Configurations
      - ./docker/nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./docker/nginx/conf.d/:/etc/nginx/conf.d

        #Nginx Configurations for you Sites:

        # - Nginx Server block
      - ./sites/example.com/site.conf:/etc/nginx/sites-available/example.com.conf
        # - Copy Public Folder:
      - ./sites/example.com/root/public/:/var/www/example.com/public
    ports:
      - "80:80"
      - "443:443"
    depends_on:
      - php-fpm
    restart: always

If it's mounted in PHP and is not mounted in Nginx, it will give a 404 Page Not Found error.

Example (Will throw 404 Page Not Found Error):

version: '3'

services:
  php-fpm:
    build:
      context: ./docker/php-fpm
    volumes:
      - ./sites/example.com/root/public/:/var/www/example.com/public
  nginx:
    build:
      context: ./docker/nginx
    volumes:
        #Nginx Global Configurations
      - ./docker/nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./docker/nginx/conf.d/:/etc/nginx/conf.d

        #Nginx Configurations for you Sites:

        # - Nginx Server block
      - ./sites/example.com/site.conf:/etc/nginx/sites-available/example.com.conf
    ports:
      - "80:80"
      - "443:443"
    depends_on:
      - php-fpm
    restart: always

And this would work just fine (mounting on both sides) (Assuming everything else is well configured and you're facing the same problem as me):

version: '3'

services:
  php-fpm:
    build:
      context: ./docker/php-fpm
    volumes:
      # Mount PHP for Public Folder
      - ./sites/example.com/root/public/:/var/www/example.com/public
  nginx:
    build:
      context: ./docker/nginx
    volumes:
        #Nginx Global Configurations
      - ./docker/nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./docker/nginx/conf.d/:/etc/nginx/conf.d

        #Nginx Configurations for you Sites:

        # - Nginx Server block
      - ./sites/example.com/site.conf:/etc/nginx/sites-available/example.com.conf
        # - Copy Public Folder:
      - ./sites/example.com/root/public/:/var/www/example.com/public
    ports:
      - "80:80"
      - "443:443"
    depends_on:
      - php-fpm
    restart: always

I hope this helps someone, And if anyone knows more about this please let me know, Thanks!
