Is there any way to download a file from my website which is hosted on a vps?

I have recently bought a VPS and hosted a simple-looking website on it (without even a domain) and I want to download a file from it via direct link (let's say my website is hihi.com and I want to host a file on it, so i can get a link like hihi.com/2H3DX3D and it will start saving a file). Is there any way/app to do that?
