Deploying a Minecraft server in Yandex Cloud

Using the tutorial, you will deploy a Minecraft (Java Edition) server of the current version in Yandex Cloud on a virtual machine running Ubuntu 22.04.

To deploy a Minecraft server of the current version in Yandex Cloud:

1. Prepare your cloud.
2. Create a security group.
3. Create a VM for the Minecraft server.
4. Install the required utilities.
5. Download and run the Minecraft server.
6. Test the solution.

If you no longer need the resources you created, delete them.

Prepare your cloudPrepare your cloud

Sign up for Yandex Cloud and create a billing account:

1. Go to the management console and log in to Yandex Cloud or create an account if you do not have one yet.
2. On the Yandex Cloud Billing page, make sure you have a billing account linked and it has the ACTIVE or TRIAL_ACTIVE status. If you do not have a billing account, create one.

If you have an active billing account, you can go to the cloud page to create or select a folder for your infrastructure to operate in.

Required paid resourcesRequired paid resources

The infrastructure support cost includes:

• Fee for continuously running VMs (see Yandex Compute Cloud pricing).
• Fee for using public IP addresses and outgoing traffic (see Yandex Virtual Private Cloud pricing).

Create a security groupCreate a security group

Create a security group with a rule allowing traffic to port 25565. This port is set by default in the server configuration file.

Create a VM for the Minecraft serverCreate a VM for the Minecraft server

1. Create an SSH key pair:

   ssh-keygen -t ed25519
   

   We recommend leaving the key file name unchanged.

2. Create a VM with a public IP address:

   Management console

   1. In the management console, select the folder to create your VM in.

   2. In the list of services, select Compute Cloud.

   3. In the left-hand panel, select Virtual machines.

   4. Click Create virtual machine.

   5. Under Boot disk image, select the Ubuntu 22.04 LTS image.

   6. Under Location, select an availability zone to place your VM in.

   7. Under Disks and file storages, configure the boot disk:

      • Type: HDD
      • Size: 18 GB

   8. Under Computing resources, navigate to the Custom tab and specify the Minecraft server recommended parameters:

      • Platform: Intel Ice Lake
      • vCPU: 2
      • Guaranteed vCPU performance: 100%
      • RAM: 2 GB

   9. Under Network settings:

      • In the Subnet field, specify the ID of a subnet in the new VM’s availability zone. Alternatively, you can select a cloud network from the list.

        • Each network must have at least one subnet. If there is no subnet, create one by selecting Create subnet.

        • If you do not have a network, click Create network to create one:

          • In the window that opens, specify the network name and select the folder to host the network.
          • (Optional) Select the Create subnets option to automatically create subnets in all availability zones.
          • Click Create network.

      • In the Public IP field, select Auto to assign the VM a random external IP address from the Yandex Cloud pool or select a static address from the list if you reserved one in advance.

      • In the Security groups field, select the minecraft-sg security group you created earlier.

   10. Under Access, specify the information required to access the VM:

       • In the Login field, enter the username of the user to be created on the VM, e.g., ubuntu.

         Alert

         Do not use root or other usernames reserved by the operating system. To perform operations requiring superuser permissions, use the sudo command.

       • In the SSH key field, paste the contents of the public key file.

         You need to create a key pair for the SSH connection yourself. To learn how, see Connecting to a VM via SSH.

   11. Under General information, specify the VM name: minecraft-server.

   12. Click Create VM.

   Recommended virtual machine configuration:

   Configuration	Number of players	vCPU	RAM	Disk size
   Minimum	1-4	2	1GB	minimum 150MB HDD
   Recommended	5-10	2	2GB	minimum 200MB HDD
   Ideal	10+	4	4GB	minimum 200MB SSD

   Warning

   Note that this configuration table reflects the default settings defined in server.properties. The bigger the world grows, the higher the requirements, especially for RAM. The larger the rendered areas of the game world, villages, and other dynamic objects, the higher the virtual server requirements.

Install the required utilitiesInstall the required utilities

1. Use SSH to connect to the created VM.

2. Install the necessary Java packages from the repository and the screen utility to run the terminal session in background mode:

   sudo add-apt-repository -y ppa:openjdk-r/ppa && sudo apt update -y && sudo apt install -y openjdk-17-jre-headless screen
   

Download and run the Minecraft serverDownload and run the Minecraft server

1. Create a separate directory and navigate to it:

   mkdir minecraft-server && cd minecraft-server
   

2. Follow the link and copy the URL to download the distribution of the current server version.

3. Download the distribution to the current directory using wget:

   wget -O minecraft_server_1.20.4.jar https://piston-data.mojang.com/v1/objects/8dd1a28015f51b1803213892b50b7b4fc76e594d/server.jar
   

4. Create the eula.txt file to automatically accept the terms of the EULA:

   cat << EOF > eula.txt
   eula=true
   EOF
   

5. Run the background screen session:

   screen
   

6. In the background session, run the server:

   java -Xms1024M -Xmx1024M -jar minecraft_server_1.20.4.jar nogui
   

   Wait for the game world to be successfully completed.

   [09:18:58] [Worker-Main-2/INFO]: Preparing spawn area: 81%
   [09:18:59] [Worker-Main-2/INFO]: Preparing spawn area: 82%
   [09:19:00] [Worker-Main-2/INFO]: Preparing spawn area: 83%
   ...

   [09:19:09] [Server thread/INFO]: Done (92.666s)! For help, type "help"
   

7. (Optional) You can leave the screen session running in the background using the control + a + d hotkeys and return to the main terminal of the virtual machine.

   To return to the background session with the server running, if there is only one such background session, run the following command:

   screen -r
   

   If there are multiple background sessions, get a list of them by running the following command:

   screen -list
   

   Result:

   There is a screen on:
      24257.pts-0.mcft-test	(02/28/2024 09:17:15 AM)	(Detached)
   1 Socket in /run/screen/S-username.
   

   Then enter the session using its ID from the list:

   screen -r 24257
   

8. After running the server, new directories and the necessary files for server operation and configuration will be created in the directory, including the logs:

       4096 Mar 16 09:50 .
       4096 Mar 16 09:52 ..
          2 Mar 16 09:16 banned-ips.json

Test the solutionTest the solution

1. Add the server to the list of servers in the Minecraft client. Give the server a name of your choice. In the Server address field, specify the public IP address assigned to our virtual machine when it was created.

   

2. In the list of servers, select the server you added and click Connect.

   

How to delete the resources you createdHow to delete the resources you created

To stop paying for the resources you created:
