title: How to create a downloadable public link for files on server
body: <p>I am afraid my question could be very stupid, and also be duplicate. But I didn't manage to find what I want after looking for some similar questions on this site. </p>
  
  <p>My question is simple, I have a big file, i.e. 1GB on my Ubuntu server, and I want to share this file with other users. How can I create a URL address for public users, in other words, when one user click this URL, the download will automatically start without demanding a username and password, just like we download many stuff (pdf, music) when we find an usable url with google. </p>
  
  <p>Someone suggests me to setup an anonymous ftp. I think it's a possible solution, but I didn't succeed to accomplish it. Can some one give me more details how I achieve my goal, (with or without ftp will both ok). </p>
  
  <p>Thanks for any help, and I am very grateful for some examples, or some tutorials !</p>
