Can you dig it? Here’s how to set up a dedicated Terraria server

Terraria is a game best experienced with a group of your friends. While the game provides an easy option for setting up a quick multiplayer session via the “Host & Play” mode, this doesn’t allow for a persistent online world as the game session is closed when the host player leaves the game. Luckily, setting up a dedicated server for you and your friends to explore, craft, and collect in Terraria is easy to learn, so long as you have the opportunity to get some hands-on time with the game’s server tools. That said, follow the handy guide below and you’ll be crafting with your friends in a dedicated Terraria server in no time.

Setting up the Server

First, you’ll want to navigate to your Terraria install folder. If you’re running the game through Steam, the default installation location should be C:\Program Files (x86)\Steam\steamapps\common\Terraria. Once there, open TerrariaServer.exe to launch the server config window and bring up a list of all available worlds.

Tip: Create a shortcut to TerrariaServer.exe on your desktop for easy access.

Each world is stored locally on your computer’s hard drive. If you have not created a world yet, or wish to start a new one, type “n” into the command line and hit Enter key to create it. You will then get a prompt to set the world size — 1=small, 2=medium, and 3=large — and name it. The world will generate after completing the aforementioned steps, and once done, you will be able to select it as the server’s dedicated world.

To select a world for the server, type in the corresponding number in the “choose world” field. Afterward, you can make the following configurations:

  • Set maximum number of players. The default is eight, but you may specify a number other than that as the server cap.
  • Set port. Unless you’re running multiple servers and need to set a different port, you can just hit enter to use the default (aka 7777).
  • Port forwarding (see below). Type “y” to enable port forwarding, or “n” if you do not wish to use it.
  • Set password. If you want to set a password for your server, type it in the field directly right of password and hit Enter. Doing so without typing anything will mean there is no password for the server.

After this, the world will be set and playable for all those who connect to the server. If you wish to change the settings for the world, you can do so from within the server console window. Changes can be made on the fly, too, even while you’re playing. This allows you to implement changes in your Terraria world in real-time. You can make the following configurations to your server:


If you’re planning on playing with others who are not connected to the same LAN/router as the host computer, you will need to know your router’s global IP address — which you can find here — and need to set up “Port Forwarding” for your Terraria server so others can access it. Port Forward also offers detailed instructions for specific routers, broken down by make and model.

Connecting to the server

Once you’ve got a server up and running, the next obvious step is to connect to it.

In order to connect to the server from the same computer on which it’s hosted:

Step 1: Launch Terraria as you would normally.

Step 2: Select Multiplayerthen Join via IP.

Step 3: Select the character you wish to use.

Step 4: When asked for the IP address, type in either “localhost” or “”

In order to connect to the server from a different computer than the one on which it’s hosted:

Step 1: Launch Terraria as you would normally.

Step 2: Select Multiplayerthen Join via IP.

Step 3: Select the character you wish to use.

Step 4: When asked for the IP address, type in the global IP address for the router the server PC is connected to.

In order to connect to the server if players will be playing on the same local connection:

Step 1: Find your computer’s IPv4 address. To do so, type “cmd” into the search bar of your Windows Start Menu and run the Command Prompt. Once open, type “ipconfig” in the window and press Enter. Your IPv4 address will be displayed beneath “Ethernet Adapter Local Area Connection” or “Wireless LAN adapter Wireless Network Connection 2.”

Step 2: Launch Terraria as you would normally once you have the IPv4 address.

Step 3: Select Multiplayerthen Join via IP.

Step 4: Select the character you wish to use.

Step 5: When asked for the IP address, use the IPv4 address for the PC the server is hosted on.

Both Internet and LAN players can connect to the server simultaneously, as long as the server and network have been properly configured.

All that’s left to do is enjoy your new dedicated server. Happy digging!
