20 Player Highend Free Minecraft Server on Oracle Cloud


Oracle Cloud offers some free resources over the oracle cloud infrastructure. This can be used to create a powerful Free Minecraft server.

By the end of the post, you should be able to create a Minecraft server on the cloud for your kids and teens.

There may be other hostings that may provide free servers but generally, the configuration of those servers are pretty weak. Here we will create a server with the configuration of up to 4 CPU cores and 24 GB of RAM. Isn’t that great from Free from one of the best enterprise cloud providers in the world!

I will try to go as simple as possible so that newbies can also follow and set up a server successfully. If you are new to cloud computing read some articles on cloud computing basics and understand what is saas and paas.

Why should you host on Free Oracle Cloud? 

Oracle has partnered with leading vendors to provide Arm server-side development and provides options to create VM that uses Ampere arm chip. These VMs are better as compared to x86 systems. They provide better performance with workloads like web applications, AI Inferencing and more.

So the free Minecraft server on oracle cloud with Arm based computing will be more powerful compared to a Minecraft server not using Ampere arm chip.

    image 71 Free Minecraft Server 10

    After few minutes you will receive an email from oracle with the login link. [Get started Now with Oracle Cloud]

  12. Check Access Details

    image 72 Free Minecraft Server 11

    The email content will have the access details. click on the button ‘Sign in to Oracle Cloud’

    P.S Sometimes there may be a small delay in receiving this message as it takes some time in doing the provisioning, so just give some time.

  13. Login with SSO

    image 73 Free Minecraft Server 12

    When you click on sign in it will take to SSO page where you can enter the username and password which you set previously.

  14. Create VM (Virtual Machine)

    image 75 Free Minecraft Server 13

    Once you log in successfully you will see this landing page with quick actions. To create a Minecraft server or any server you need an operating system. So the first step after landing at the OCI console is to create an Operating system.

    To do that Click on Create a VM instance.

  15. Create the compute instance configuration

    image 76 Free Minecraft Server 14

    Give a name to you VM instance (e.g Minecraft Server). Note the Edit buttons , We will use this to edit the default configurations in next steps.

  16. Change Image Shape

    image 77 Free Minecraft Server 15

    In the shape dialog, select the ‘Instance type’ of ‘Virtual Machine’ and then select ‘Ampere’ (ARM) under ’Shape series’. Choose the ‘VM.Standard.A1.Flex’ shape and choose the amount of CPU and RAM that you want to allocate to this server. For your “always free” ARM servers, you get up to 4 OCPU and 24 GB of RAM to allocate. This means that you can turn up one virtual machine with 4 OCPU and 24GB of RAM, or 4 servers each with 1 OCPU and 6GB of RAM (or any combination up to the limit). It just depends on what you want to dedicate to each VM! 

  17. Select Ampere image

    image 78 Free Minecraft Server 16

    Select Ampere image and note the OCPU =1 and Memory = 6 by default. We will change that in the next step

  18. Increase CPU and RAM

    image 79 Free Minecraft Server 17

    – Select the ‘Instance type’ of ‘Virtual Machine’ and then
    – Select ‘Ampere’ (ARM) under ’Shape series’.
    – Choose the ‘VM.Standard.A1.Flex’ shape and
    – Choose the amount of CPU and RAM that you want to allocate to this server.

    Click on the down arrow and move the OCPU and RAM Slider to the desired power. Here we are setting to 2 OCPU and 6 GB RAM.

    The Free ARM server provides up to 4 OCPU and 24 GB of RAM. So you can allocate up to 4 Server machines and distribute the 24 GM as you want.
    e.g 4 CPU with 6 GB RAM each OR
    2 servers with 2 CPUs each with 12 GB RAM
    or any combination based on your VM server requirement.

  19. Confirm the changes in VM

    image 80 Free Minecraft Server 18

    After the selection you have made confirm the configuration in VM is of 2 Core OCPU and 6 GB memory.

  20. Configure Networking and Assign Public IP

    image 81 Free Minecraft Server 19

    The next step would be to create a network to which the VM server has to be connected. So choose a virtual cloud network (VCN). Give VCN name and enter subnet name. If there are any default values you can just accept the defaults.

    Finally, make sure you check the radio button Assign a Public IP Address. This is a public IP address and can be accessed from external networks. This will be used for your partner players to connect over the internet.

  21. Create Public Private SSH Key Pair

    image 82 Free Minecraft Server 20

    Save the keys to your local system and store them safely. you will need the private key to connect later.
    Also if you already have a Public-Private key beforehand you can upload the public key using the upload public key files, or paste public keys radio buttons.

  22. Configure Boot Volume

    image 83 Free Minecraft Server 21

    Leave the boot volume as default

  23. The Server provisioning Starts

    image 84 Free Minecraft Server 22

    It takes a few minutes to provision the server configuration .

  24. Confirm a Running server

    image 85 Free Minecraft Server 23

    Once provisioned the icon changes to green and shows running . Note the Public IP and copy it somewhere.

  25. Connect Using SSH to Public IP

    image 87 Free Minecraft Server 24

    Connect via ssh (in Windows 10) to the public IP you just copied from the local system. Select yes for the above message.

    NB: SSH is a secure shell and is used to create secure connections. The commands to connect via ssh may be different for different operating systems (mac, ubuntu, Linux, windows etc).

    This example is done for windows 10.
    And if you face any issue on windows you can also try using Putty. Putty is software to create secure connections. you can download it from here.

  26. If using Putty Convert the key

    image 1 Free Minecraft Server 25

    Note that Putty doesn’t understand the key you downloaded so you need to convert the key.

    You can use PuttyGen to convert the downloaded private key. When you install Putty , PuttyGen also gets installed . Run PuttyGen from the windows start search menu

    Copy the converted key to .ssh folder in windows 10.

  27. keep the private key in .ssh folder

    image 89 Free Minecraft Server 26

    The local windows default path is C:\Users\USER_NAME\.ssh

  28. Open Putty

    image 90 Free Minecraft Server 27

    Now Connect the Public IP with putty. Enter public IP in Hostname as per image. Don’t hit Open yet. Hit Open after loading private key in next step

  29. Connect using Private Key

    image 91 Free Minecraft Server 28

    go to SSH tab > Auth > browse for the local converted private key from .ssh folder ( or any folder you have kept) and hit the Open button

  30. Login as opc

    image 92 Free Minecraft Server 29

    Once you come to command prompt login as :
    enter opc and you would be connected. You can run any Linux command to test.
    $ ls
    $ ls -l

  31. Check for Java

    image 94 Free Minecraft Server 30

    Run the below command at $ prompt

    $ yum list jdk*

    This will list the available packages. Copy the Jdk filename of the latest version.

  32. Install latest JDK

    image 95 Free Minecraft Server 31

    Copy the latest jdk file name from the above step and run the below command. Note the Jdk filename is appended

    sudo yum install jdk-

    confirm with y when asked for installation.

  33. Monitor the installation

    image 96 Free Minecraft Server 32

    You will see a confirmation when jdk is successfully installed.
    Enter $ java –version at the command prompt the confirm

    You will see the version output as

    java version “” 2021-06-29
    Java(TM) SE Runtime Environment (build
    Java HotSpot(TM) 64-Bit Server VM (build, mixed mode)

  34. Install MineCraft Server

    So now we are ready to install the Minecraft server
    Download the latest Minecraft jar file from Minecraft Server Download Page on to the VM server.

    Note that if you click on the link it will get downloaded to your local system which we do not need to do. Just copy the link and use the command in the next step on the server.

  35. Copy the Jar File link

    image 97 Free Minecraft Server 33

    There is a jar file that needs to be downloaded and run on the server.

  36. Run the Download Command (Wget) on cloud

    image 2 Free Minecraft Server 34

    wget https://launcher.mojang.com/v1/objects/0a269b5f2c5b93b1712d0f5dc43b6182b9ab254e/server.jar

    This will download it to the Cloud VM server.
    The next step is to install.

  37. Try Installing

    Run below command
    $ java -Xmx1024M -Xms1024M -jar server.jar nogui

    This is supposed to fail and you may see this and we need to accept the licence agreement.

    [19:35:33] [main/ERROR]: Failed to load properties from file: server.properties
    [19:35:33] [main/WARN]: Failed to load eula.txt
    [19:35:33] [main/INFO]: You need to agree to the EULA in order to run the server. Go to eula.txt for more info.

    EULA – End user license agreement.

  38. Edit eula.txt

    image 98 Free Minecraft Server 35

    Edit eula.txt with Vi editor or nano editor whichever you are comfortable with. You can see the text from the command by typing

    $ cat eula.txt

  39. Set EULA to true

    image 99 Free Minecraft Server 36

    If using nano editor to save exit, type CTRL+C, ‘Y’ to accept changes, and then ENTER
    If using Vi editor do the changes and press SHIFT+wq!

  40. After changes verify the EULA

    image 100 Free Minecraft Server 37

    Confirm EULA.txt is set to true
    using the command
    $ cat eula.txt

  41. Open Firewall and Security List Ports to Allow External Internet Access

    image 101 Free Minecraft Server 38

    Go to subnet in the VM server image

  42. Edit Default Security list

    image 103 Free Minecraft Server 39

    Click on default security list

  43. Enter Ingress Rule for TCP Protocol ( Incoming Traffic)

    image 104 Free Minecraft Server 40

    Enter CIDR for source type
    Source CIDR as
    and Destination PORT as 25565
    25565 is the port where Minecraft server allows incoming connections

  44. Enter Ingress Rule for UDP protocol

    image 105 Free Minecraft Server 41

    Enter another ingress rule for UDP protocol with similar values

  45. Open the ports on VM’s Firewall

    image 106 Free Minecraft Server 42

    Run the below commands

    sudo firewall-cmd –permanent –zone=public –add-port=25565/tcp
    sudo firewall-cmd –permanent –zone=public –add-port=25565/udp
    sudo firewall-cmd –reload

    It should show ‘Success’ and the ports would be opened.

  46. Now Start the Minecraft Server

    image 107 Free Minecraft Server 43

    Use the below command to start the Minecraft server. Note that this command failed earlier as EULA was not accepted.

    $ java -Xmx1024M -Xms1024M -jar server.jar nogui

    In a few minutes, the Minecraft server will be up and running! You can now connect up to your server using the public IP address and start playing on your own server! 

    And in case you need to modify the server configuration for accepting more Load you can always do it by following the Tutorials/Setting up a server – Official Minecraft Wiki (fandom.com)


By following the above steps you can set up a powerful and flexible Free Minecraft Server on Oracle Cloud infrastructure. You can change the server configuration for more load as well.


Is the server Really Free?

Yes, Unless you manually want to increase Compute configuration and agree to payments manually. For Minecraft server this is enough.

Is there any other payment method?

As of now only credit card is the option. You may try a debit card or any virtual gift cards from a bank and see if it works.

Can I install using mobile?

Yes . Just follow the step using a mobile Internet browser.

How to fix com.mojang.authlib.gameprofile Connection error?

If you get error like com.mojang.authlib.gameprofile@6cdbc4f2[id= try resetting the value of online-mode to false. This generally happens if the Minecraft version is modded or not registered. so be careful and understand the consequences.

Once connected to server from command prompt run ls -l (on linux vm)
[opc@minecraft-server-2021 ~]$ ls -l
total 79712
-rw-rw-r–. 1 opc opc 2 Jul 6 06:27 banned-ips.json
-rw-rw-r–. 1 opc opc 2 Jul 6 06:27 banned-players.json
-rw-rw-r–. 1 opc opc 180 Jun 30 06:12 eula.txt
drwxrwxr-x. 2 opc opc 4096 Jul 6 06:27 logs
-rw-rw-r–. 1 opc opc 2 Jul 6 06:27 ops.json
-rw-rw-r–. 1 opc opc 43621201 Jun 8 11:03 server.jar
-rw-rw-r–. 1 opc opc 37962360 Jan 14 16:09 server.jar.1
-rw-rw-r–. 1 opc opc 1038 Jul 6 06:27 server.properties
-rw-rw-r–. 1 opc opc 109 Jul 6 06:28 usercache.json
-rw-rw-r–. 1 opc opc 2 Jun 30 06:29 whitelist.json
drwxrwxr-x. 12 opc opc 4096 Jul 6 06:42 world

then do $cat server.properties
This will show the file contents
[opc@minecraft-server-2021 ~]$ vi server.properties

Here you can edit(use vi or nano editor) the file to set the value of online-mode to false. After changing try connecting again.

Why you are not able to ping the Public IP of Cloud VM?

By default, ping is not allowed on the public IP of VM. You need to enable ICMP in the ingress rule on the cloud subnet to enable pinging the IP. See example

How to keep the Minecraft server Running 24×7?

You can keep the Minecraft server running in background by installing screen
$sudo yum install screen
Once installed create a screen
$ screen minecraftscreen
$java -Xmx1024M -Xms1024M -jar server.jar nogui

To exit the screen, hit CTRL+A and then click on your “d” key afterward.
this will make the server run in the background.
To reattach the screen enter
screen -r

How to add more RAM to the Minecraft server?

Just change the memory parameter while starting.
java -Xmx****M -Xms****M -jar server.jar nogui
e.g java -Xmx2048M -Xms2048M -jar server.jar nogui for 2 GB Ram
