Nginx webserver

nginx safer and easier to configure compared to apache
we're using PUT to upload files

Start and configure webserver

New directory to handle uploaded files
sudo mkdir -p /var/www/uploads/SecretUploadDirectory
Change owner to www-data
sudo chown -R www-data:www-data /var/www/uploads/SecretUploadDirectory
Create config file
/etc/nginx/sites-available/upload.conf should contain (port number can be anything):
server {
listen 9001;

location /SecretUploadDirectory/ {
root /var/www/uploads;
dav_methods PUT;
}
}
Symlink our Site to the sites-enabled Directory
sudo ln -s /etc/nginx/sites-available/upload.conf /etc/nginx/sites-enabled/
Start Nginx
sudo systemctl restart nginx.service

Errors

Check /var/log/nginx/error.log for errors
We can remove default config if port 80 is already in use
sudo rm /etc/nginx/sites-enabled/default

Upload and verify

Upload file
curl -T /etc/passwd http://localhost:9001/SecretUploadDirectory/users.txt
Verify if file is present:
sudo tail -1 /var/www/uploads/SecretUploadDirectory/users.txt
