How to run Node.js server on https on own server

I have developed a web console made in Angular JS and running it on Node.js server.

Similarly I have deployed Angular Web Console on our own server(Linux) but its running on HTTP.

I want to run it on HTTPS now but how can I do that as I have no background of security. Where I can start from and what would be the steps to achieve the goal.

Thanks in Advance. :)
