How do I change the world on my server?

I want to set my single player world as the world on my server. I know this is simple enough, but this is my first time running a server, and I am not sure how to go about doing this.

Any advice?

 

What do you mean by "change"?

If you want it to be your one and only world, open server.properties AFTER THE SERVER IS OFF and change the world name to the name of your world's folder, then put the world's folder in the same directory as the server.properties and craftbukkit.

If you want it to be multiworld and have portals or tp commands between them, download MultiVerse, run the plugin once, then put your world folder in the main server directory. Then use /mvimport <WorldFolderName> <Normal or Nether>. After it says "Done!", use /mvtp <WorldFolderName>. If you need help with MultiVerse, just post back here again.

 

Small, but meaningful steps. Treat your fellow man with compassion, and show it in your actions.

Be the change you want to see in your world, on your server.
