Palworld Server Management

The scripts in this repository will help you mitigate the memory leaking problem of Palworld on Linux server and do auto backup for you.

Encapsulate the Server into a Service

Modify the parameters inside palw.service to your own and put it under /etc/systemd/system/. Then run the following commands

sudo systemctl daemon-reload
sudo systemctl enable palw.service

After that the Palworld server will auto-start after system starts. We can control the server with the following commands

sudo systemctl start palw.service 		      	# start server
sudo systemctl stop palw.service				# stop server
sudo systemctl restart palw.service				# restart server	
sudo systemctl status palw.service				# check log and status

Mitigate Memory Leaking Problem

Modify the Service

Set the following entries under [Service] in the service file (it's already modified in repo):

RuntimeMaxSec=24h
MemoryMax=14G
Restart=always

Note that you may change the values according to your own configuration.

Create a Swap Area

We can create a swap area using the following commands.

sudo fallocate -l 16G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
echo "/swapfile none swap sw 0 0" | sudo tee -a /etc/fstab

You can change the size and name of the swap file according to your own favor.

After executing the above commands, use the following command to view the newly created swap partition.

swapon --show

Auto Backup

backup.sh will automatically backup server saving file.

Change the values inside backup.sh to your own, and edit crontab for steam user by running

crontab -e

Then add the following job

# m h  dom mon dow   command
0 */2 * * * /home/steam/scripts/backup.sh

Also, you can add the following entry in the service file to auto backup when server stops.

ExecStopPost=/home/steam/scripts/backup.sh -cold

-cold adds an extra postfix to the backup file name to indicate that the backup is triggered by server stop.
