### Who is this for?

This is an introductory topic for developers who are new to Oracle Cloud Infrastructure (OCI) and want to provision an arm64 instance and run a persistent Minecraft server on it.

### What will you learn?

After completing this Learning Path, you'll be able to perform the following tasks:

- Provision an OCI A1 arm64 virtual machine instance suitable for running a Minecraft server
- Deploy and configure Minecraft server software
- Expose the Minecraft service from OCI by editing the network policy for the instance and the local firewall
- Connect to the running Minecraft server from the Minecraft client application

### Prerequisites

Before starting, you'll need the following prerequisites:

- An Oracle Cloud Infrastructure (OCI) account
- A copy of the [Minecraft Java Edition client](https://www.minecraft.net/en-us/download) installed, and [a license for the game](https://www.minecraft.net/en-us/store/minecraft-java-bedrock-edition-pc)
- A Microsoft account for starting a Minecraft client application

### Summary

You’ll provision an Arm-based Ampere A1 virtual machine (VM) on Oracle Cloud Infrastructure (OCI), install the required Java runtime, and deploy a Minecraft Java Edition server. First, you’ll set up the OCI VM instance and update security ingress rules. Then, you’ll configure a persistent terminal session so the server continues running after SSH disconnects. With the server running, you’ll update the server-side local firewall, start the Minecraft Java Edition client, and connect to the server to validate the deployment.

### Frequently asked questions

**Which OCI shape and image should I choose for the server?**

Create an Arm-based Ampere A1 instance with Oracle Linux 9.

**Which Java package should I install on the Arm instance?**

For Minecraft 26 or earlier, install Java 25 OpenJDK for aarch64. Use: `sudo dnf install java-25-openjdk.aarch64 -y`.

**How do I keep the Minecraft server running after I close my SSH session?**

Use `tmux` to create a persistent terminal session and start the server inside that session. You can disconnect and later reattach to the `tmux` session without stopping the server.

**Which port do I need to open on the VM, and how?**

Open TCP port `25565` in the Linux firewall. Run: `sudo firewall-cmd --permanent --add-port=25565/tcp` and `sudo firewall-cmd --reload`.

**I opened the VM firewall but the client still can't connect. What should I check?**

Verify the OCI network policy for the instance allows inbound TCP traffic on port `25565` to the VM. Update the OCI security settings if needed, then try connecting again.
