How to Set Up a Terraria Dedicated Server

Overview

Terraria is a 2D sandbox adventure game supporting up to 16 players on a dedicated server. Here is how to set one up on your Breeze.

Requirements

• A Breeze with at least 1 GB RAM
• Ubuntu 22.04 or newer

Step 1: Create a Server User

sudo useradd -r -m -d /opt/terraria terraria
sudo mkdir -p /opt/terraria/server

Step 2: Download the Server

cd /opt/terraria/server
sudo -u terraria wget https://terraria.org/api/download/pc-dedicated-server/terraria-server-LATEST.zip
sudo -u terraria unzip terraria-server-*.zip
# Move files from the extracted linux directory
sudo -u terraria mv */Linux/* .
sudo -u terraria chmod +x TerrariaServer.bin.x86_64

Step 3: Create a Server Configuration

sudo -u terraria tee /opt/terraria/server/serverconfig.txt <<EOF
world=/opt/terraria/server/worlds/MyWorld.wld
autocreate=3
worldname=MyWorld
maxplayers=8
port=7777

EOF
