Demo

See the real world example at uguu.se.

Requirements

Original development environment is Nginx + PHP5.3 + SQLite, but is confirmed to work with Apache 2.4 and newer PHP versions like PHP7.3.

Install

For the purposes of this guide, we won't cover setting up Nginx, PHP, SQLite, Node, or NPM. So we'll just assume you already have them all running well.

NPM/Node is only needed to compile the files, Uguu runs on PHP.

Compiling

First you must get a copy of the uguu code. To do so, clone this git repo.

git clone https://github.com/nokonoko/uguu

Assuming you already have Node and NPM working, compilation is easy.

Run the following commands to do so, please configure dist.json before you compile.

cd uguu/
make
make install

OR

make install DESTDIR=/desired/path/for/site

After this, the uguu site is now compressed and set up inside dist/, or, if specified, DESTDIR.

Configuring

Front-end related settings, such as the name of the site, and maximum allowable file size, are found in dist.json. Changes made here will only take effect after rebuilding the site pages. This may be done by running make from the root of the site directory.

Back-end related settings, such as database configuration, and path for uploaded files, are found in includes/settings.inc.php. Changes made here take effect immediately. Change the following settings:

define('UGUU_DB_CONN', 'sqlite:/path/to/db/uguu.sq3');
define('UGUU_FILES_ROOT', '/path/to/file/');
define('UGUU_URL', 'https://subdomainforyourfiles.your.site');

If you intend to allow uploading files larger than 2 MB, you may also need to increase POST size limits in php.ini and webserver configuration. For PHP, modify upload_max_filesize and post_max_size values. The configuration option for nginx webserver is client_max_body_size.

Edit checkdb.sh and checkfiles.sh to the proper paths:

sqlite3 /path/to/db/uguu.sq3 "DELETE FROM files WHERE date <= strftime('%s', datetime('now', '-1 day'));"

find /path/to/files/ -mmin +1440 -exec rm -f {} \;

Then add them to your crontab:

0,30 * * * * bash /path/to/checkfiles.sh
0,30 * * * * bash /path/to/checkdb.sh

These scripts check if DB entries and files are older then 24 hours and if they are deletes them.

MIME/EXT Blocking

Blocking certain filetypes from being uploaded can be changed by editing the following settings in includes/settings.inc.php:

define('CONFIG_BLOCKED_EXTENSIONS', serialize(['exe', 'scr', 'com', 'vbs', 'bat', 'cmd', 'htm', 'html', 'jar', 'msi', 'apk', 'phtml']));
define('CONFIG_BLOCKED_MIME', serialize(['application/msword', 'text/html', 'application/x-dosexec', 'application/java', 'application/java-archive', 'application/x-executable', 'application/x-mach-binary']));

By default the most common malicious filetypes are blocked.

Using SQLite as DB engine

We need to create the SQLite database before it may be used by uguu. Fortunately, this is incredibly simple.

First create a directory for the database, e.g. mkdir /var/db/uguu.
Then, create a new SQLite database from the schema, e.g. sqlite3 /var/db/uguu/uguu.sq3 -init /home/uguu/sqlite_schema.sql. Then, finally, ensure the permissions are correct, e.g.

chown www-data:www-data /var/db/uguu
chmod 0750 /var/db/uguu
chmod 0640 /var/db/uguu/uguu.sq3

Finally, edit includes/settings.inc.php to indicate this is the database engine you would like to use. Make the changes outlined below

define('UGUU_DB_CONN', '[stuff]'); ---> define('UGUU_DB_CONN', 'sqlite:/var/db/uguu/uguu.sq3');
define('UGUU_DB_USER', '[stuff]'); ---> define('UGUU_DB_USER', null);
define('UGUU_DB_PASS', '[stuff]'); ---> define('UGUU_DB_PASS', null);

NOTE: The directory where the SQLite database is stored, must be writable by the web server user

Nginx example config

I won't cover settings everything up, here are some Nginx examples. Use Letsencrypt to obain a SSL cert.

Main domain:

server{
    
    listen	        443 ssl;
    server_name		www.yourdomain.com yourdomain.com;

    ssl on;
    ssl_certificate /path/to/fullchain.pem;
    ssl_certificate_key /path/toprivkey.pem;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;    

    root /path/to/uguu/dist/;
    autoindex		off;
    access_log      off;
    index index.html index.php;  

    location ~* \.(ico|css|js|ttf)$ {
    expires 7d;
    }

    location ~* \.php$ {
	fastcgi_pass unix:/var/run/php/php7.3-fpm.sock;
        fastcgi_intercept_errors on;
        fastcgi_index index.php;
        fastcgi_split_path_info ^(.+\.php)(.*)$;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

        error_page 404 /4041x.html;
        error_page 403 /4041x.html;
        location /4041x.html {
        root /home/neku/www;
      }
}

Subdomain serving files (do not enable PHP here):

server{
    listen          443 ssl;
    server_name     www.subdomain.serveryourfiles.com subdomain.serveryourfiles.com;

    ssl on;
    ssl_certificate /path/to/fullchain.pem;
    ssl_certificate_key /path/to/privkey.pem;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    
    root            /path/where/uploaded/files/are/stored/;
    autoindex       off;
    access_log	    off;
    index           index.html;
}

To redirect HTTP to HTTPS make a config for each domain like so:

server {
    listen 80;
    server_name www.domain.com domain.com; 
    return 301 https://domain.com$request_uri;
}

API

To upload using curl or make a tool you can post using:

curl -i -F files[]=@yourfile.jpeg https://uguu.se/upload.php (JSON Response)
