Oracle Free Tier

Walkthrough for using Oracle Free Tier hosting.

Create and configure your cloud machine

Access the Oracle website. Click on View accounts, then click on Sign up for free Cloud Tier.

Click on Start for free, fill out the form, and create your account. Sign in with your Oracle account. If your account is under validation, wait a few minutes before proceeding with the steps. Click on Set up a network with a wizard. Select Create VCN with internet Connectivity, and click on Start VCN Wizard.

Fill in VCN name and disable the option Use DNS hostname in this VCN, click on Next, and wait.

Click on VCN name to create rules. Select Public-Subnet-network, and then click on Default Security List for network.

Click on Add Ingress Rules, and create the following rules for:

• Protocol TCP

  • Port range: 80, 443, and 7777

  • Select Stateless option

• Protocol UDP

  • Port range: 80, 443, and 7777

  • Select Stateless option

Go to Homepage and click on Create a VM Instance. Fill out Computer instance name, and click on Edit in the Image and shape group.

Click on Change image, select Canonical Ubuntu, OS Version 18.04, and click on Select Image.

In the Network group, check if the network is the one created in the previous steps.

In Add SSH Keys, click on Save Private Key. Save this in a safe place; it will be necessary to access your machine.

In Boot Volume, you can specify HD Size, or you can use your 100 GB in one machine. Click on Create and wait. Go back to Home, click on Dashboard > Compute > Instance, select your instance, and copy IP Address.

Access your machine

Open the PowerShell editor and type the following command:

ssh -i [ssh_key_place] ubuntu@[machine_ip]

Example:

ssh -i c:\users\user\desktop\ssh-key-2021-09-15.key ubuntu@0.0.0.0

If you get an error while trying to connect to your cloud machine, you can fix it by right-clicking on ssh-key, select properties > security > advanced > remove inheritance, and delete all other users, keeping only your Windows user.

After you connect, run the following commands to add firewall rules into Ubuntu:

sudo apt install firewalld
sudo firewall-cmd --zone=public --add-port=7777/tcp --permanent
sudo firewall-cmd --zone=public --add-port=7777/udp --permanent
sudo firewall-cmd --reload

Download FileZilla, and follow the steps below to connect to your cloud machine using your ssh-key:

Create Build

In Unity, access File > Build Settings > Select Linux > Mark Server Build. Wait for the build to finish, and then upload your files with FileZilla.

This tutorial uses a server folder, but this is optional.

Use the following commands:

ssh -i c:\users\user\desktop\ssh-key-2021-09-15.key ubuntu@0.0.0.0
cd server
chmod +x ./[your_project_name].x86_64
./[your_project_name].x86_64

Your server should now be running!
