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?

Upon completion of this Learning Path, you will be able to:

  • 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 will need the following:

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.

?
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.
