Preparation

Install unzip and tmux.

Warning

Since screen is now deprecated, we recommend using tmux.

sudo apt update
sudo apt install unzip tmux

Next, open port 19132 for the server to use. To reduce lag, use UDP.

sudo ufw allow 19132/udp
sudo ufw reload

Create a server management user.

Since you’ll be switching users frequently, a short username is easier. This time, I chose “mc”.

sudo adduser mc

Switch the user to mc and create the server directory.

su - mc
mkdir bedrock

Download

https://www.minecraft.net/en-us/download/server/bedrock

Download the server from the official website.
Check the boxes for “Ubuntu (Linux)” and “I agree to the Minecraft End User License Agreement and Privacy Policy” then click “Download.”

Information

By changing the version part of the download link”https://www.minecraft.net/bedrockdedicatedserver/bin-linux/bedrock-server-1.21.114.1.zip“, you can also download older server versions.

List of past versions → Bedrock Dedicated Server – Minecraft Wiki

Once the download is complete, move the file to the directory you created earlier. If you downloaded it on another PC, transfer the file using a USB drive or SSH.

Specify the directory and then unzip.

cd bedrock
unzip bedrock-server-x.xx.xxx.x.zip -d ./server

Confirm the operation

After unzipping the files, run ./bedrock_server within the directory.

When joining a server,
go to “Play” → “Servers” → “Add Server” → enter the IP address or domain name of your server in “Server Address”.

Warning

To stop the server, enter “stop” to shut it down.

Server Management Script

Closing the terminal where the server is running will also stop the server, so we’ll use tmux to run it in the background.
However, entering commands to manage the server manually is quite annoying.
Therefore, I referenced the script from the following site. It’s a script that manages starting, stopping, and backing up the site’s server all at once. Honestly, this site is easier to understand than mine.

esac

The usage is the same as the site I referenced.

When executing the script, specify start, stop, s_backup, f_backup, or status as arguments.

systemd

Configure settings for auto start. Enable management via the systemctl command. This configuration also references the site mentioned earlier.

exit
sudo nano sudo vi /etc/systemd/system/bedrock_server.service

Switch to the sudo user, then create the file.

[Unit]
Description=Minecraft Bedrock Server
After=network.target local-fs.target

[Service]
Type=forking
User=mⅽ
ExecStart=/home/mc/bedrock/server/script.sh start
ExecStop=/home/mc/bedrock/server/script.sh stop

[Install]
WantedBy=multi-user.target

Auto Start & Management

After creating the systemd file, register the service.

sudo systemctl enable bedrock_server.service

Next, we’ll set up cron to automatically run start → stop → full backup.
Before that, we’ll configure the system so that regular users (mc) can manage the server. Giving full permissions is risky, so we’ll restrict access to only the necessary commands.

sudo visudo

# Add the following
mc ALL=NOPASSWD: /bin/systemctl start bedrock_server, /bin/systemctl stop bedrock_server, /bin/systemctl restart bedrock_server

Switch to the mc and edit the cron file.

crontab -e

#　Add the following

#　Server shutdown at 2:00 AM daily
0 2 * * * sudo systemctl stop bedrock_servern
#　Full backup at 2:10 AM daily
10 2 * * * /home/mc/bedrock/server/script.sh f_backup
# Server start at 3:00 AM daily
0 3 * * * sudo systemctl start bedrock_server
