TIP - you will likely need to right click on the version of Terraria that you want, copy link location and then type the command 'wget' followed by pasting the link to the download.  This will download that version of Terraria to your current location on the linux server.

Example: 

If you were to want Terraria 1.4.3 version, your command would look like the following:

Downloads (link to Terraria Server Downloads)

Once downloaded, within the downloads folder, run the following command

Unzip <Name of the downloaded server file>

sudo chmod +x TerrariaServer.bin.x86* 

Launch the server

./TerrariaServer.bin.x86_64

Finally,

The screenshot above lists the new world I created "Hworld". To create your own type "n" and it will prompt you for a name and difficulty level. 

Set the maximum number of players: I set mine to the max of 16

Set the port: Hit enter to use the default, 7777.

Enable port forwarding: type "y"

Set your password: I entered none since I prefer no passwords for my server.

To connect to the server, simply Launch Terraria and select multiplayer > join via IP. Then select a player and when asked for an IP type "localhost"
