Apache not parsing PHP behind Nginx reverse proxy

Nginx Apache PHP

I’m trying to build an Ubuntu 18.04 based, Apache PHP-FPM web server with multiple virtual hosts, behind Nginx as a reverse proxy. Everything works fine up to the point where I configure Nginx to be the reverse proxy. Now I have this:

  • static HTML files are OK

  • php files are downloaded instead of executed

  • the worst thing is that when I try to fetch my info.php (which only has the basic HTML5 scaffold with title meta tag, to know which virtual host is served, and <?php phpinfo(); ?>) I’m being served with the different file, without a clue from where it was served.

When bypassing Nginx on port 8080 everything is back to normal and my PHP is working.

Here’s my /etc/nginx/sites-available/apache (my_server_ip is real IP):

server {
    listen 80;
    server_name foobar.net www.foobar.net test.io www.test.io;

    location / {
        proxy_pass http://my_server_ip:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

I’ve lost two days so far, I found no similar issues on the web, and I’m desperate so any help would be greatly appreciated.

Cheers.

Hello, @WebshapedBiz

May I ask if you use or have installed php-fpm as well? The thing is that you will need it in order to serve those requests.

Looking forward to your reply.

  • Thank you @alexdo for your time and effort. Yesterday, late-night, I’ve solved my problem.
    Sure I had php-fpm installed because I had no problems without Nginx serving as a reverse proxy.
    It seems that the problem was this line:
    server_name foobar.net www.foobar.net test.io www.test.io;
    When I changed it to:
    server_name _;
    everything came back to normal.

    I don’t understand it since the former line had a correct syntax but there you are.

    Cheers.

    • I’m glad you’ve sorted this. Thanks for sharing the solution you’ve found for the issue.

      Regards,
      Alex
