VPS with Ubuntu 18.04 NGINX Downloads PHP FILE

Question

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; server_name localhost; listen 443 ssl default_server; listen [::]:443 ssl default_server; ssl_certificate /etc/letsencrypt/live/asdfsf.net/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/sdafasdf.net/privkey.pem; 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

Answer 1

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).
