I am trying to create a system where USB on Raspberry Pi will be auto mounted and the files can be accessed via an Apache server running over local hotspot from the same Raspberry Pi through a script written in PHP.

I am successful in all the steps and file names are visible via a local hotspot except that when the files are accessed, it is showing a 404 error.

  • The index.php is located on /var/www/html/index.php
  • The files are located on /media/usb0

I have tried changing the file permission to 777 (just to check) but nothing worked for me.

Is there a solution?

  • I have found it necessary to change the permissions on each file.

  • Isn't it accomplished by sudo chmod -R /foldername? I tried the same but no luck.

I found the solution myself.

The trick is: linking the the two folders by a symbolic link Opening terminal from within the "files" folder (/var/www/html/files on the Pi), and type:

sudo ln -s /media/usb1

(I was running pmount to automount and allocate the name usb1 to any USB attached to Pi.
