VPS with Ubuntu 18.04 NGINX Downloads PHP FILE

cn flag
Mihai Andrei Maria

I have a VPS with:

  • Ubuntu 18.04
  • Nginx
  • Php7.2-fpm

The server runs Ruby on rails project as homeurl (example.com) and wordpress as directory (example.com/blog) . First the VPS was configured with Apache2, made everything work fine, untill i had to integrate a live chat. Had to switch to Nginx for Action Cable.

Now, the chat app works fine, on RoR, but if i try to access the blog i get the index.php file to download, it does not execute.

Here is my nginx default conf:

# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# https://www.nginx.com/resources/wiki/start/
# https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/
# https://wiki.debian.org/Nginx/DirectoryStructure
#
# In most cases, administrators will remove this file from sites-enabled/ and
# leave it as reference inside of sites-available where it will continue to be
# updated by the nginx packaging team.
#
# This file will automatically load configuration files provided by other
# applications, such as Drupal or Wordpress. These applications will be made
# available underneath a path with that package name, such as /drupal8.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

# Default server configuration

server { 

        listen   80; ## listen for ipv4; this line is default and implied
        listen   [::]:80 default_server ipv6only=on; ## listen for ipv6
        index index.php index.html index.htm index.nginx-debian.html;

        root /var/www/html/public;
        passenger_enabled on;
        passenger_ruby /usr/local/bin/ruby;

location /var/www/html/public {
        try_files $uri $uri/ =404;
    }

    

location ~ ^/blog(/.*|$) {

 root /var/www/html/public/blog;
        
         try_files $uri $uri/ /blog/index.php?$args;
        passenger_enabled off;       
        index index.php;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        fastcgi_param DOCUMENT_ROOT $realpath_root;

        }

location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
   
        }


}

Spent 3 night on troubleshoting I cant get it right. Any hint is very welcomed. Thank you

You have two regex matching locations and you don't have fastcgi_pass directive in the first one. Regex matching locations are checked from the first to the last one, so the second location (where you do have fastcgi_pass directive) will never be reached. That means any PHP file accessed with the /blog/ URI prefix will be treated as a simple file and will not be passed to the PHP-FPM backend for execution. You can use two nested locations instead:

location ~ ^/blog(/.*|$) {
    passenger_enabled off;       
    index index.php;
    try_files $uri $uri/ /blog/index.php?$args;
    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        fastcgi_param DOCUMENT_ROOT $realpath_root;
        fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
    }
}

You don't need to define root /var/www/html/public/blog; for this location. You already have root /var/www/html/public; at the upper level, so nginx will search file index.php requested as /blog/index.php in the /var/www/html/public/blog directory (see the difference between root and alias nginx directives).

If your `index.php` located in the `/var/www/html/public/blog` directory, remove `root` directive from this location.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
