Hey i want to install a wordpress-site to my debian10 server with nginx but just cant get things to run. To reduce problems i created simplest possbile “hello world” index.html and index.php files for testing.
<html>
<head>
<title>PHP-Test</title>
</head>
<body>
<?php echo '<p>Hallo Welt</p>'; ?>
</body>
</html>
When ive the index.html in my directory /var/www/EXAMPLE.COM it shows the example site correctly, but whatever i try, when i replace it with the index.php testsite it always shows “502 - Bad Gateway”.
For server administration i use the amp-webinterface (which uses nginx too) on the subdomain amp.EXAMPLE.COM, but i guess that shouldnt be a problem. (that webinterface is working completly fine)
server {
listen 80;
listen [::]:80;
server_name amp.EXAMPLE.COM;
if ($host = amp.EXAMPLE.COM) {
return 301 https://$host$request_uri;
}
return 404;
}
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name amp.EXAMPLE.COM;
# Replace the below as appropriate according to certificate locations and
# whatever SSL settings you want. The below reflects a standard certbot
# configuration
ssl_certificate /etc/letsencrypt/live/amp.EXAMPLE.COM/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/amp.EXAMPLE.COM/privkey.pem;
include /etc/letsencrypt/options-ssl-nginx.conf;
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
location / {
proxy_pass http://localhost:8080; # Or whatever local IP and port ADS is listening on
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_send_timeout 86400s;
proxy_http_version 1.1;
proxy_redirect off;
proxy_buffering off;
client_max_body_size 10240M;
# The following nine lines will only work if nginx and AMP are on the same host
error_page 502 /NotRunning.html;
location = /NotRunning.html {
root /opt/cubecoders/amp/shared/WebRoot;
internal;
}
location /shared/ {
alias /opt/cubecoders/amp/shared/WebRoot/;
}
}
}

}
}
ssl_certificate /etc/letsencrypt/live/EXAMPLE.COM/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/EXAMPLE.COM/privkey.pem; # managed by Certbot
}
instead of fastcgi_pass i already directly linked to the php8.0-fpm.sock but it didnt changed anything, so i switched to this location block i found online.
Gave perms alrady with sudo chmod -R 755 /var/www/EXAMPLE.COM/ sudo chown www-data:www-data -R /var/www/EXAMPLE.COM/ and always restartet nginx. I also removed old php7.3, now only have 8.0 remaining and installed php8.0-fpm (php8.0-fpm is positive responding to systemctl status (see below); php-fpm is not)

Hello,
As far as I can see you have set up Nginx to proxy the traffic to port 9001. However it is quite possible that the PHP-FPM service is not listening on that port.
To check this you could run the following command:
netstat -plant | grep 9001
If this is the case, you could check the listen address for your PHP FPM service in the PHP FPM config file. If it is set to Unix Socket file, you might have to update your Nginx config to match the PHP FPM configuration.
For more information on how to do that I would recommend the following tutorial:
