Ubuntu: Install QR code service #PHP #Nginx #Markdown
To generate QR codes with php we are using the project QR Generator PHP hosted on GitHub.
Clone project with git.
cd /usr/local/src
sudo git clone https://github.com/janikvonrotz/QR-Generator-PHP.git
Rename the project directory to get a shorter url.
sudo mv QR-Generator-PHP qr
Add the config to one of your Nginx sites.
server{
    
    ...
    
    # change location for QR code requests
    location /qr{
        root /usr/local/src;
        index index.php;
    }
    
    location ~ .php$ {
        
        ...
        
        # change the php root for QR code requests
        if ($request_uri ~* /qr) {
            set $php_root /usr/local/src;
        }
        
        ...
    }
}
Test config and reload Nginx service.
sudo nginx -t && sudo service nginx reload
