How to Set Up and Run a Minecraft Server with Forge and Mods on OCI Free Tier

Oracle Cloud Infrastructure (OCI) offers a generous always-free tier, making it a fantastic option to host a modded Minecraft server. This guide will walk you step-by-step through setting up a Minecraft server with Forge and mods, even if you’re a complete beginner.

Step 1: Sign Up for Oracle Cloud Free Tier

  1. Visit Oracle Cloud’s Free Tier page.
  2. Click on "Start for Free" and create an account. You’ll need to provide a valid email, phone number, and credit card for verification (no charges will be made).
  3. Once your account is set up, log in to the Oracle Cloud Console.

Step 2: Create a Virtual Machine Instance

  1. In the Oracle Cloud Console, go to Compute > Instances.
  2. Click on "Create Instance".
  3. Fill in the details:
    • Name: Enter "MinecraftServer".
    • Image and Shape:
      • Click "Edit" next to "Image and Shape".
      • Image: Select Ubuntu 22.04.
      • Shape: Choose the Ampere A1 instance with 4 OCPUs and 24 GB of RAM.
    • Networking:
      • Select the default Virtual Cloud Network (VCN) and subnet automatically created by Oracle.
    • Add SSH Key: Paste the public SSH key from your local machine. If you don’t have an SSH key:
      • Run ssh-keygen on your computer to generate a key pair.
      • Use the public key located at ~/.ssh/id_rsa.pub.
  4. Click "Create" to launch your instance.

Step 3: Connect to Your Instance

  1. Open a terminal on your computer.
  2. Connect to the instance using SSH: 
    ssh -i ~/.ssh/id_rsa ubuntu@<instance-public-ip>
    Replace <instance-public-ip> with the public IP address of your instance (found in the OCI Console under your instance details).

Step 4: Install Java and Required Tools

  1. Update the package list: 
    sudo apt update && sudo apt upgrade -y
  2. Install Java: 
    sudo apt install openjdk-17-jre -y
  3. Install other tools: 
    sudo apt install unzip wget -y

Step 5: Download and Set Up Minecraft Server

  1. Create a directory for the Minecraft server: 
    mkdir ~/minecraft && cd ~/minecraft
  2. Download the latest Minecraft Forge installer for the server from Forge’s official website.
    • Copy the direct download link for the installer version.
    • Use wget to download: 
      wget <forge-installer-url>
      Replace <forge-installer-url> with the copied link.
  3. Run the Forge installer: 
    java -jar forge-*.jar --installServer
  4. Accept the EULA: 
    echo "eula=true" > eula.txt

Step 6: Set Up Mods

  1. Download your desired mods from a trusted source like CurseForge.
  2. Upload the mod files to your server using SCP: 
    scp -i ~/.ssh/id_rsa <mod-file>.jar ubuntu@<instance-public-ip>:~/minecraft/mods
    Replace <mod-file>.jar with the name of your mod file.
  3. Ensure all mods are compatible with the Forge version you installed.

Step 7: Open the Required Port

  1. In the Oracle Cloud Console, go to Networking > Virtual Cloud Networks.
  2. Click on your default VCN.
  3. Select the Subnet used by your instance.
  4. Under Security Lists, click on the default security list.
  5. Add a new ingress rule:
    • Source CIDR: 0.0.0.0/0 (to allow connections from anywhere).
    • IP Protocol: TCP.
    • Source Port Range: Leave blank.
    • Destination Port Range: 25565 (Minecraft’s default port).
  6. Save the rule.

Step 8: Start the Server

  1. Navigate back to the Minecraft server directory: 
    cd ~/minecraft
  2. Start the server: 
    java -Xmx8G -Xms8G -jar forge-*.jar nogui
    • Replace 8G with the amount of RAM you want to allocate (adjust based on your mods and server needs).
  3. Keep the terminal session open to keep the server running, or use a tool like tmux to run it in the background: 
    sudo apt install tmux -y
tmux
java -Xmx8G -Xms8G -jar forge-*.jar nogui
    • Detach from tmux by pressing Ctrl+B and then D.

Step 9: Connect to Your Server

  1. Open Minecraft on your computer and select the same version as your Forge server.
  2. Go to Multiplayer and click Add Server.
  3. Enter your server’s public IP address and click Done.
  4. Join the server to start playing.

Is Docker Still Relevant in 2025? A Practical Guide to Modern Containerization

-
  Docker took the IT world by storm when it was first released in 2013, introducing a simple yet powerful way to create, deploy, and manage containerized applications. Fast forward to 2025, and the containerization landscape has grown exponentially, with tools like Kubernetes, Podman, and Buildah gaining traction. So, is Docker still relevant? Let’s dive in. Docker's Core Strengths Docker remains one of the most user-friendly and widely adopted containerization tools. Its key features include: Ease of Use : Docker’s CLI and Docker Compose make it simple for developers to build and run containerized applications. Rich Ecosystem : Docker Hub is still the go-to repository for prebuilt images. Cross-Platform Support : Seamless operation across various platforms ensures it remains a top choice for development. For small to medium-sized projects, Docker’s simplicity makes it invaluable. It's a great choice for development environments, prototyping, and quick deployments. The Competit...

Going In With Rust: The Interview Prep Guide for the Brave (or the Mad)

-
 Why Rust? (No, Seriously, Why?)      Choosing Rust as your language for a coding interview is, at best, bold — and at worst, borderline reckless. Rust is not known for being ergonomic under time pressure. Unlike Python or Java, it doesn’t hold your hand when you’re fumbling through edge cases and messy input. The compiler is famously strict, and while that’s great for production code, it can feel like an enemy in a 45-minute interview. Forget about “just trying something” — Rust will make you justify every move. Want to mutate a value inside a loop? Better understand borrowing rules. Need a linked list? Be ready to bring in Rc , RefCell , and a prayer. Want to pass a slice around without cloning everything? Ownership will make you earn it. Many LeetCode problems assume a fast, flexible language — Rust is neither of those, out of the box. There’s no REPL. You can’t “just print stuff” — not without fighting the borrow checker and formatting macros. Even simple operati...

Becoming an AI Developer Without the Math PhD: A Practical Journey into LLMs, Agents, and Real-World Tools

-
 For the past year, the world has been obsessed with what artificial intelligence can do for us. From ChatGPT writing emails to MidJourney generating fantastical images, the dominant narrative has been "how to use AI." But what if you're not satisfied just prompting models? What if you want to build them, customize them, run them offline, and deploy them securely in the cloud? This is the journey I'm starting now: learning to build with AI, not just use it. And in this post, I’ll lay out the core principles, motivations, and roadmap that will guide my exploration into becoming an AI developer—with a specific focus on LLMs (Large Language Models), agents, training workflows, and cloud/offline deployment . Let me be clear: I’m not here to write a research paper, derive equations, or become a machine learning theorist. I don’t need to build a transformer from scratch in NumPy. My goal is pragmatic: I want to learn how to train, run, integrate, and deploy powerful ...
