File Uploader

A simple file uploader application that allows authenticated users to upload, list, and delete files. The application uses PHP and a Python authentication service running on Apache2.

Prerequisites

• Apache2, configured, up and running
• PHP 8.1 or higher
• Required PHP extensions: php-json, php-curl

Hint:

sudo apt update
sudo apt install apache2
sudo apt install php libapache2-mod-php

Installation

For simplicity, I'll use my current Ubuntu instance user name, you should replace by yours.

Clone

git clone https://github.com/yourusername/uploader.git
cd uploader

or download this repository

wget https://github.com/sensboston/uploader/archive/refs/heads/master.zip
unzip master.zip -d uploader
mv uploader/uploader-master/* uploader/
rm -r uploader/uploader-master
rm master.zip

Configure PHP

Ensure the following PHP settings are in your /etc/php/8.1/apache2/php.ini:

log_errors = On
error_log = /var/log/php_errors.log

Also check for max upload file/post size limits in /etc/php/8.1/apache2/php.ini (adjust to your needs, like 10G):

upload_max_filesize = 10M
post_max_size = 10M

Create the upload directory and set the necessary permissions:

sudo mkdir -p /var/www/html/upload
sudo chown -R www-data:www-data /var/www/html/upload
sudo chmod -R 755 /var/www/html/upload

Do not forget to add proper permissions to www-data (used by apache & php)

sudo chown -R www-data:www-data /var/www/html/upload
sudo chmod -R 775 /var/www/html/upload

Create application directory at webroot (or configure app/site):

(note: with my Apache configuration, I just need to create a subdirectory)

sudo mkdir -p /var/www/html/uploader

Edit file config.php and adjust variables

(website name, time zone etc.)

sudo nano /home/ubuntu/uploader/config.php

Copy all app files (html, php & js) to the app folder:

sudo cp /home/ubuntu/uploader/*.* /var/www/html/uploader/

Restart Apache to apply changes:

sudo systemctl restart apache2

Usage

Open your web browser and navigate to https://yourserveraddress/uploader

Enter your username and password to authenticate.

Choose a file to upload and click the "Upload" button.

The uploaded files will be listed on the page, and you can delete them using the "Delete" button.

Issues / TODO

• Add checking upload size before starting upload.
