Install Minecraft server on ARM architecture using Oracle Cloud Infrastructure.

The server will be installed as a container using the Docker client and will retain the server's data in the directory '/etc/mc-server/minecraft-data', by default. To evert data loss when the server encounters applicative issues or data corruption, the 'mc-backup' script will run on a daily basis, using a CRON job backing up the server's data to the directory '/tmp/minecraft-backup' and will keep snapshots of data older less than 10 days.

Server Usage

Server maintainance

To restart the mc-server, run the following command:

sudo docker restart mc-server

For viewing server logs:

sudo docker logs mc-server

To delete the mc-server Docker container:

sudo docker rm -f mc-server

Server Backup/Restore

Backup MC-Server:

mc-backup

Restore server backup:

mc-restore

After a successful restore it might take a few minutes to start the server up and we should see the following at the end of the startup process:

sudo docker logs -f mc-server

[01:11:25] [Worker-Main-2/INFO]: Preparing spawn area: 96%
[01:11:25] [Worker-Main-1/INFO]: Preparing spawn area: 97%
[01:11:26] [Worker-Main-1/INFO]: Preparing spawn area: 98%
[01:11:26] [Worker-Main-2/INFO]: Preparing spawn area: 98%
[01:11:27] [Server thread/INFO]: Time elapsed: 101506 ms
[01:11:27] [Server thread/INFO]: Done (164.863s)! For help, type "help"

The retore command will take the latest MC-Server snapshot and restore it to the Minecraft /etc/mc-server/minecraft-data data directory. The restoration process will stop the Docker container, delete the current data residing in /etc/mc-server/minecraft-data, and restore the latest snapshot located under the /home/$USER/minecraft-backup directory.

In case the restore process does not work as expected, consider performing a manual restore process.

Server Configuration

OCI VM Configuration

TODO

Machine access

When creating a VM in OCI, we will have an option to generate a SSH keypair and using the private key for authentication.

To access the machine, SSH to the VM using the key for authentication:

ssh -i ~/.ssh/mc.key user@123.123.123.123

Installation

To install mc-server, first clone this repo:

git clone https://github.com/davidpinhas/mc-server.git
cd mc-server

Than, run the installation script to start the MC-Server with specific memory size allocated to the service:

sudo bash mc-init.sh $NUMBER

For example, we can pass '20' to allocate 20GB of memory for the service:

sudo bash mc-init.sh 20

In case a digit wasn't passed during the script startup, the MC-Server Docker container will start with the default value of 4GB memory limit.

Post Installation

After successfully running the script, in order to modify the mc-server configuration file, run:

sudo vim /etc/mc-server/minecraft-data/server.properties
