Can multiplayer server side run on Linux?

I will be developing a multiplayer Unity2d game. Development will be on OS X .

However once completed, I would like the server side of the game to run on a Linux box. Any instructions? In other words is there such thing a server only component?

Thanks

If you are writing your server in Unity then you can export to and run on Linux (also headless and with no graphics).

There is no “server only” component as such.
