Preparing your Network [ ]

Before you brainstorm setting up the server, consider these network changes that may be necessary if your server is in your home network.

Assign the computer running the server a static IP address. It is unlikely, but if yous don't practise this then your router may reassign the computer's IP accost while yous are using the server which will interfere with your connectedness to it. To learn how to do this with your router, refer to your router's transmission or search "how to set up static IP on <brand and model of your router>".
If anyone is connecting to the server from outside your local area network (aka "over the internet"), you will need to forward the port for the server. Additionally, make certain you have assigned the server calculator a static IP on your router. See beneath on how to forward ports.

Opening a port accessible through your public IP: [ ]

To find your external IP, a simple website can display your public IP address without any unnecessary details, such as whatsmyip.com or ipify (has a lot more than features at ipify.org/).
You will accept to port forrard (port 7777 by default, annotation that this is the same port equally Ark: Survival Evolved, Mordhau, Just Crusade 2: Multiplayer mod, and San Andreas Multiplayer) for Terraria. (port forward guide).

Windows [ ]

Local Surface area Network (LAN): [ ]

From the kickoff button, go to Program Files>Accessories>Command Prompt. This will display a new window chosen Control Prompt.
Type the give-and-take "ipconfig" without the quotes and hit enter. Some information volition display similar to the screenshot you see hither.
Look for Ethernet Adapter Local Area Connection' or 'Wireless LAN adapter Wireless Network Connection two', find 'IPv4 Address', which is your computer'due south IP accost on your local network. This window also shows other data including the default gateway. You volition need the default gateway to configure your router in a browser like Firefox or Chrome.

Setting upwardly a server [ ]

Beginning, decide whether you want to beginning a "Host & Play" multiplayer game, or a dedicated server game. See multiplayer for an explanation of the differences.

Setting upwards a "Host & Play" server [ ]

This is the simplest way of playing multiplayer, and works well for in-home LAN or curt online co-op games. Start Terraria, and in the main menu, choose "Multiplayer" and so "Host&Play". Select a world to play in (or create a new one) so enter a password (or leave blank if yous would prefer no password).

First launch of your dedicated server [ ]

Guide setting up a server 01.png

To launch your server for the first fourth dimension, we won't worry about a configuration file, as the Terraria server file has a nice multiple-step wizard to get it running quickly.

The dedicated server files are located in the folder where the Terraria files are.

GOG Milky way example: C:\GOG Galaxy\Games\Terraria
Steam example: C:\Program Files (x86)\Steam\steamapps\common\Terraria

You tin can also download the dedicated server files directly from terraria.org by clicking the "Dedicated Server" link at the lesser of the folio.

First, try setting upwardly a server without a configuration file. To practise this, search for the binder where Terraria is installed, find TerrariaServer.exe so run it. A window will open up and show the server control interface. This is where you lot can enter commands or view information. When it starts, it should ask you to cull a world, listing the worlds currently available on your computer. The window also gives the choice to create or delete worlds at startup. When making a new earth, follow the instructions in the window to modify sure aspects of the world generation.

Annotation: By default, Terraria saves all worlds into "C:\Users\UserName\Documents\MyGames\Terraria\Worlds".

Setting up dedicated server with configuration file [ ]

To run a server with a pre-made configuration file y'all must search for your Terraria installation folder, then run "TerrariaServer.exe -config <serverconfigfile>", where <serverconfigfile> is the configuration file.

Use cmd, go to Terraria folder and blazon in "TerrariaServer.exe -config <serverconfigfile> " without the quotation marks, then ↵ Enter .
Make a shortcut of "TerrariaServer.exe", right-click on it, click on "Properties", edit the field "Target:" (originally: "<...>\TerrariaServer.exe"), blazon at the cease, after "TerrariaServer.exe" the following: " -config <serverconfigfile> " without the quotation marks (important, go out a SPACE between the ".exe" and the "-config"). It should look like this: ""<...>\TerrariaServer.exe" -config <serverconfigurationfile>" Then apply it. From now on this shortcut will starting time your server with the given configuration file.
If y'all want to, you tin can make a batch file as well, in its function it's the same equally a shortcut. Offset, you make a new text file (.txt), then edit information technology in whatsoever kind of simple editor (not Office, something like Notepad), and then type in the commands like this:

@echo off

cls

TerrariaServer.exe -config <serverconfigurationfile>

Then save the text file (.txt) as a batch file (.bat). You lot will accept to place the batch file in the Terraria folder to get in work and the configuration file must be in the aforementioned folder as well. Otherwise, if y'all type in the total path for the "TerrariaServer.exe" and the <serverconfigurationfile> it will piece of work anywhere and act as a shortcut. Instance for full path:

"C:\Games\Terraria\TerrariaServer.exe -config D:\TerrariaCon\case.txt"

Information technology is possible to run more than i server from one reckoner! Simply to do then at that place are three important things:

Make sure each server uses different configuration files!
Make sure each server uses unlike worlds!
Make sure each server uses different port numbers!

Annotation: It is recommended y'all make each server a dissever shortcut/batch file.

Configuration file and save game data location [ ]

The configuration file will be located in the directory where Terraria resides.

Steam example: C:\Program Files (x86)\Steam\steamapps\mutual\Terraria
GOG Milky way example: C:\GOG Milky way\Games\Terraria
World location: C:\Users\Defaults\My Documents\My Games\Terraria\Worlds\

Linux / macOS [ ]

Most all of the setup on Linux and macOS is done in the terminal. If you are inexperienced with the command line, you may be understandably intimidated or worried you will break something. Merely take information technology slow and blazon in commands exactly as they are written hither. You are encouraged to research each command so you lot know exactly what it will do (eg man ip or chmod --help). If you need help learning basic terminal commands, consider this guide by HowToGeek.

Local Area Network (LAN): [ ]

Example output of `ip addr` with of import info highlighted

On GNU/Linux, FreeBSD, and macOS type ip addr in the concluding to view your local IP address. You should see something similar to the screenshot.

Look for Broadcast and state UP. In this example your local IP address is 192.168.i.44 from inet 192.168.1.44/24 .

Alternatively y'all can run ifconfig as root for a like output if your organisation does non have ip installed.

Setting upwardly a server [ ]

First, decide whether y'all want to start a "Host & Play" multiplayer game, or a dedicated server game. Encounter multiplayer for an caption of the differences.

Setting up a "Host & Play" server [ ]

This is the simplest mode of playing multiplayer, and works well for in-home LAN or short online co-op games. Start Terraria, and in the main carte, choose "Multiplayer" so "Host&Play". Select a world to play in (or create a new i) then enter a password (or get out blank if you would prefer no password).

First launch of your dedicated server [ ]

Running the server with no configuration will take you to the world select screen

To launch your server for the showtime fourth dimension, we won't worry about a configuration file, as the Terraria server file has a dainty multiple-footstep magician to get it running quickly.

On Linux and macOS, the binary is constitute in $STEAM_ROOTDIR/steam/steamapps/common/Terraria. You can too download the dedicated server files direct from terraria.org by clicking the "Dedicated Server" link at the bottom of the page.

Running the script TerrariaServer volition get-go the right version of the server for your system. Make certain the script and programme files have execute permissions past using the command chmod u+x TerrariaServer*. If you lot do not see this script so double check that you are using the latest version of the server.

Since the server will stop if the terminal session is ended, y'all tin can use a program similar tmux or screen to keep the session running while you are logged out.

Similar with other game servers, it is generally recommended that you create a user (with dwelling house directory) defended to running game servers. This ensures that servers don't have permissions to alter files they shouldn't be.

The server volition neglect to start if $TERM is not set to xterm. If this is the problem the server will generate a file called "customer-crashlog.txt" which volition incorporate the error "Organisation.Exception: Magic number is wrong: 542" If this is the case, simply run the control "export TERM=xterm" and outset the server over again.

Note: By default, Terraria saves all worlds into "~/.local/share/Terraria" on Linux and "~/Library/Awarding Support/Terraria/Worlds" on macOS

Setting upward dedicated server with configuration file [ ]

To run a server with a pre-fabricated configuration file you must search for your Terraria installation binder, then run "TerrariaServer -config <serverconfigfile>", where <serverconfigfile> is the configuration file. Follow these steps to create a shell script to automatically run the server with a configuration file.

Using a text editor, create a file in the same directory as the Terraria server file called startserver.sh
Copy the post-obit lines of text into the file:

#!/bin/sh

./TerrariaServer -config <serverconfigfile>
Save the file, make sure it has execution privileges by running chmod +x startserver.sh, and run it.

You can too use the full path for "TerrariaServer" and the <serverconfigurationfile> it will piece of work anywhere and act as a shortcut. Example for full path:

"~/TerrariaServer/TerrariaServer -config ~/.config/TerrariaServer/serverconfig.txt"

As you tin see in this example, the configuration file doesn't need to be in the Terraria binder.

It is possible to run more than one server from one computer! Merely to practise so there are iii important things:

Brand sure each server uses different configuration files!
Make sure each server uses different worlds!
Make certain each server uses different port numbers!

Annotation: It is recommended yous make each server a separate beat script.

Save game information location [ ]

macOS [ ]

~/Library/Awarding Back up/Terraria/Worlds

Linux [ ]

~/.local/share/Terraria/Worlds

NOTE: If the default installation directory was inverse during installation a binder called "~" volition be created in which the relieve information can be constitute, this is Non the same thing every bit the users habitation directory.

Making a configuration file [ ]

The configuration file options and syntax is the same regardless of OS. At that place is an example configuration file in the Terraria folder. Information technology looks similar this if you open up it in a text editor like Notepad or Notepad++. If y'all don't run across it, you can copy this text into a new file.

#this is an example config file for TerrariaServer.exe #employ the control 'TerrariaServer.exe -config serverconfig.txt' to use this configuration or run start-server.bat #please report crashes past emailing crashlog.txt to back up@terraria.org

#the following is a list of bachelor command line parameters:

Globe size is specified by: 1(modest), two(medium), and 3(large). #-banlist <path>					Specifies the location of the banlist. Defaults to "banlist.txt" in the working directory. #-worldname <world name>             			Sets the name of the globe when using -autocreate. #-secure						Adds addition cheat protection to the server. #-noupnp						Disables automatic port forwarding #-steam							Enables Steam Support #-lobby <friends> or <private>				Allows friends to bring together the server or sets it to individual if Steam is enabled #-ip <ip address>					Sets the IP address for the server to heed on #-forcepriority <priority>				Sets the process priority for this job. If this is used the "priority" setting below will be ignored. #-disableannouncementbox				Disables the text announcements Proclamation Box makes when pulsed from wire. #-announcementboxrange <number>				Sets the announcement box text messaging range in pixels, -i for serverwide announcements. #-seed <seed>						Specifies the world seed when using -autocreate

#remove the # in front of commands to enable them.

#Creates a new world if none is found. World size is specified by: 1(pocket-size), 2(medium), and 3(large). #autocreate=i

#Sets the world seed when using autocreate #seed=AwesomeSeed

#Sets the difficulty of the world when using autocreate 0(classic), i(expert), 2(master), iii(journey) #difficulty=0

#Sets the max number of players immune on a server.  Value must be between 1 and 255 #maxplayers=8

#Set the port number #port=7777

#Gear up the server countersign #countersign=p@55w0rd

You tin run into that every line starts with a "#" sign. That sign removes the line and keeps the server from using it. This is useful for commenting in the file, like this:

#Ready the message of the day

As it explains the following command. And it is also useful for turning off commands, like:

#motd=Please don't cut the imperial trees!

Here, the server won't have "MessageOfTheDay", considering it has the # to remove information technology. So, if yous desire to employ a command you just need to delete the "#" from the first of the line. You can edit this file to your liking as much as you want. Every command is explained in the file. If you are ready, you just have to salvage the file and utilise it equally a configuration file.

Information technology is highly recommended to get out the original configuration file, make a copy of it and edit the copy, or open the original and "Save Every bit..." another file, with a different proper name.

The default location for your configuration and world files as generated past the customer and the server varies by platform.

Connecting to a Server [ ]

In the Terraria game, go to Multiplayer->Join via IP->Select your grapheme->Type in the IP for the server. This tin be the internal IP the server uses, or the external IP.

From the Host Computer [ ]

You can apply localhost as the IP, or employ the host IP.

Over the Local Network [ ]

For other computers on your local network (connected directly to your router), type in the 'IPv4' address of the computer you're running the server on (come across LAN). Each device continued to your network has their own IP accost assigned by your router. The IPv4 accost can change for each device from time to time if your router uses dynamic IP addressing (nearly routers united states dynamic IP addressing by default). Dynamic ways that the IP accost tin change.

Over the Internet [ ]

For friends connecting "over the cyberspace", they'll need to enter your external IP (significant your router'southward IP), but this won't piece of work until you gear up the aforementioned port forwarding on your router (See Port Forwarding).

On FreeBSD [ ]

How to run a dedicated terraria server on Ubuntu.

Go to your jail, create a terraria user, install screen, mono and sqlite3. Run this control once to initialize everything properly: (run across How to run a dedicated Terraria server on Ubuntu/cir0qna for details well-nigh the command)

mono --server --gc=sgen -O=all TerrariaServer.exe

Generate a earth and quit (^C)

Once you generated your world, add the code found here: http://ix.io/iHD to /usr/local/etc/rc.d/terraria and edit it according to your liking.

Edit your jail's rc.conf, terraria_enable="YES", and restart the jail.

Server lists [ ]

Once your Net server is running properly, consider posting information technology to one of the public server lists, so Net users tin notice it and join:

Server forum at Official Terraria Forum
https://world wide web.tserverweb.com
https://topg.org/terraria-servers/
http://terraria-servers.com
https://terraria.21yunbox.com

Troubleshooting [ ]

There are a few reasons something wouldn't work. You can separate many problems into these major groups.

"The server is not starting" [ ]

This is common because of a typo. Check everything again (specially if you are using a configuration file(s)), and brand sure that everything is typed correctly. If it'due south still not working properly, check the forums to meet if anyone else has the same issue that you lot take. As a terminal resort, endeavour reinstalling the game.

Others can't connect to the server [ ]

This is normally a network related problem.

Make certain they are connecting to the right IP address. This is the server estimator's IP accost (IPv4) for networked computers, or the router's Global IP address for over the net players. See the showtime department for info on how to find these.
Make certain your firewall is non blocking the "TerrariaServer.exe" or the server's port ("7777" by default).
Make certain the others bring together with the correct port number (peculiarly important if information technology's not the default "7777").
If y'all are using a router yous have to make certain it opens the server'southward port for you. See start section for info on how to exercise this.
If your IP address is dynamic (not static or reserved) information technology is possible for information technology to alter over fourth dimension, so check your IP address again. As well, if you are using Dynamic DNS to get around this problem, tell the other players to e'er type in your Domain Name to join and don't use the saved listing of connections which the game offers (the game simply saves the IP address, not the domain proper noun, then if your IP has changed it won't be aware of it).

World not saving/Items disappear from chests after closing server [ ]

The Terraria server only saves the world automatically every dawn (every 24 minutes).

If you close the server without issuing a relieve/exit command via the console (or if you utilise host and play), in that location's a chance that the globe may not have saved the last few minutes of changes. Moving gear betwixt chests and immediately closing the server without explicitly specifying the save/go out command may really cause those items to disappear.

To ensure this isn't an issue: E'er use a dedicated server, and remember to enter the "save"/"exit" commands rather than simply closing the console window via the cerise Ten button.
