Hi all,

I recently built a new PC which runs Linux Mint 20.3 on a 1 TB M2 SSD and stores multiple TB on a 3.5" HDD which is mounted at /mnt/BigMedia.

I'm writing some PHP code that I call Galleria which is supposed to take image files and display them on a page. I've set it up in two places for testing purposes. When it's run from /var/www/my-galleria, it works fine, though it can't see or connect to any files in /mnt/BigMedia/images.

I tried to fix this problem by running the same PHP code at /mnt/BigMedia/my-galleria, but when I run it from there, I get a 404 error from nginx. All the permissions for this directory are set correctly. The user and group for the directory is www-data, but this stop the errors from occurring.

Here is the my-galleria file under sites-available

server {
listen 127.0.0.20;
server_name my-galleria my-galleria.localhost;

# root /var/www/my-galleria;
root /mnt/BigMedia/my-galleria;

index index.php;

location / {
# root /mnt/BigMedia/my-galleria;
# index index.php;
try_files $uri $uri/ =404;
}

location = /favicon.ico {
return 204;
access_log off;
log_not_found off;
}

location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
}

}

Here are the latest entries from access.log

Is there some configuration setting in nginx that stops it from reaching a server root on a different drive? Is there any way to overcome this? Am I overlooking something? Let me know if more information is needed.

Thanks.
