Some Useful PalWorld Scripts

Pal World Scripts (Linux & Bash)

Remember to replace the folder directory, <AdminPassword>, <RCONPort> to your own.

Also, you need to use crontab to schedule the following scripts if necessary.

Supervisor

I'm using supervisor to restart the service, the example config is as:

[program:pal]
command="/home/steam/.local/share/Steam/steamapps/common/PalServer/Pal/Binaries/Linux/PalServer-Linux-Test" Pal -useperfthreads -NoAsyncLoadingThread -UseMultithreadForDS
numprocs=1
process_name=pal-%(process_num)d
directory=/home/steam/.local/share/Steam/steamapps/common/PalServer
user=steam
environment=HOME="/home/steam",USER="steam"
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/pal.out
stderr_logfile=/var/log/supervisor/pal.err

Backup

#!/bin/sh
DDATE=`date "+%F-%T"`
mkdir $DDATE
cp -r /home/steam/steamapps/common/PalServer/Pal/Saved/SaveGames $DDATE/

Restart

Need to:

  • Download Releases from ARRCON
  • Have your AdminPassword ready.
  • Enable RCON in Server Settings doc
#!/bin/sh

RCON_PORT=<RCONPort>
ADMIN_PASSWORD=<AdminPassword>

echo 'broadcast Auto_Reboot_Initialized' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
echo 'save' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
echo "shutdown 300 Server_is_going_to_reboot_in_5_minutes" | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 120
echo 'broadcast Server_is_going_to_reboot_in_3_minutes' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 60
echo 'broadcast Server_is_going_to_reboot_in_2_minutes' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 60
echo 'broadcast Server_is_going_to_reboot_in_60_seconds' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 50
echo 'broadcast Server_is_going_to_reboot_in_10_seconds' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 5
echo 'broadcast Server_is_going_to_reboot_in_5_seconds' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 1
echo 'broadcast Server_is_going_to_reboot_in_4_seconds' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 1
echo 'broadcast Server_is_going_to_reboot_in_3_seconds' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 1
echo 'broadcast Server_is_going_to_reboot_in_2_seconds' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 1
echo 'broadcast Server_is_going_to_reboot_in_1_second' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD

Check Memory

Need to install bc by apt install bc.

#!/bin/bash

RCON_PORT=<RCONPort>
ADMIN_PASSWORD=<AdminPassword>
THRESHOLD=80

MEMORY_USAGE=$(free | grep Mem | awk '{print $3/$2 * 100.0}')

if (( $(echo "$MEMORY_USAGE > $THRESHOLD" | bc -l) )); then
    echo "Memory usage is above $THRESHOLD%. Running clean command."
    echo "broadcast Memory_Is_Above_$THRESHOLD%" | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
    echo "save" | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
    echo "shutdown 60 Reboot_In_60_Seconds" | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
    cd ~/backups ; ./backup.sh
else
    echo "Memory usage is below $THRESHOLD%. No action required."
fi

Known Bug:

  1. Exiting the guild will cause all players who was not logged-in at the moment to corrupt their save files! (Joining another guild will exit the old one as well.) Next time they log in they'll stuck at the loading spinning black screen. You can either clean the save files of those who got corrupted or restore a backup. Now fixable by https://gist.github.com/Bluefissure/f277a3409cdaf09cddbad5983fd01f68

Yes, for the very first time executing, you need to chmod PalServer-Linux-Test in the user you're going to execute the command.
,,,

Thanks, this was issue seems like will see if it works on next restart, as well there was write access issues with how logfiles were being written in supervisor so ended up changing it to just logfile=logs/supervisord.log as it was throwing errors similar to https://stackoverflow.com/questions/35273197/unable-to-start-service-with-nohup-due-to-info-spawnerr-unknown-error-making-d

Edit: Nevermind error I was seeing, exit code 127 is just another version of command not found.

I ended up using linuxGSM and a combo of these scripts, and that is working very nicely.

https://linuxgsm.com/servers/pwserver/

I followed that, and in the home folder of /home/pwserver I put a few of my custom scripts, based on these.
and assigned crontab to them as well, in linuxgsm they mention whats recommended, and when your in user pwserver just type crontab -e to add more commands.

I added restart every 6 hours and a save command every 15 minutes (since we had some issues with roll backs before moving to linuxgsm)

restart script,

#!/bin/sh

RCON_PORT=<RCON Port>
ADMIN_PASSWORD=<admin password>

echo 'broadcast Scheduled_Server_Restart' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 1
echo 'broadcast Server_is_going_to_reboot_in_5_minutes' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 120
echo 'broadcast Server_is_going_to_reboot_in_3_minutes' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 60
echo 'broadcast Server_is_going_to_reboot_in_2_minutes' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 60
echo 'save' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
echo 'broadcast Server_is_going_to_reboot_in_60_seconds' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 50
echo 'broadcast Server_is_going_to_reboot_in_10_seconds' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 5
echo 'broadcast Server_is_going_to_reboot_in_5_seconds' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 1
echo 'broadcast Server_is_going_to_reboot_in_4_seconds' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 1
echo 'broadcast Server_is_going_to_reboot_in_3_seconds' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 1
echo 'broadcast Server_is_going_to_reboot_in_2_seconds' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
sleep 1
echo 'broadcast Server_is_going_to_reboot_in_1_second' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD
./pwserver stop
sleep 25
./backup.sh
./pwserver start

Backup Script

!/bin/bash

dt=`date +"%d-%m-%Y %T"`

cd ~

rclone copy --update --verbose --transfers 20 --retries 5 --stats 1s "/home/pwserver/serverfiles/Pal/Saved/SaveGames/" "BACKUP/current" --backup-dir="BACKUP/archive/$dt"

cd ~

Save script

#!/bin/sh

RCON_PORT=<rcon port>
ADMIN_PASSWORD=<admin password>

echo 'save' | ./ARRCON -P $RCON_PORT -p $ADMIN_PASSWORD

RCON is just the ARRCON executable in my case sitting in /home/pwserver

my crontab -e looks like

*/5 * * * * /home/pwserver/pwserver monitor > /dev/null 2>&1
*/30 * * * * /home/pwserver/pwserver update > /dev/null 2>&1
0 0 * * 0 /home/pwserver/pwserver update-lgsm > /dev/null 2>&1
*/15 * * * * /home/pwserver/save.sh > /dev/null 2>&1
0 */6 * * * /home/pwserver/restart.sh > /dev/null 2>&1

monitor is responsible for checking if server is running and restarting it if nessicary, update checks for steam updates and will stop and update server if its avaliable, I just wanted regular restarts that are graceful since linuxgsm wasn't offering that.

Ok I figured out how to make your systemd file work. with that said, I am trying to figure out how to make it also run STEAMCMD's app update prior to the server application running, any insight on this?

I'm trying to read through documentation to figure this out.

Hey @DrasticalFire, here is my systemd service file. I adapted it from a Satisfactory tutorial and it has been working perfectly since day 2 after release.

Server update? I just run systemctl restart palworld and steamcmd downloads the update and it fires back up. Power goes out? Server starts when the machine starts (assuming you do systemctl enable).

Do note that this is setup to kill the server if it hits 16GB used.

Greetings, here is my systemd file, I notice our install directories are different, would i adopt yours without the "+force_install_dir" argument? I would have to set my RAM limt to about 10-12Gigs.

[program:pal]
command="/home/steam/Steam/steamapps/common/PalServer/Pal/Binaries/Linux/PalServer-Linux-Test" Pal -useperfthreads -NoAsyncLoadingThread -UseMultithreadForDS

user=steam
environment=HOME="/home/steam",USER="steam"
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/pal.out
stderr_logfile=/var/log/supervisor/pal.err


My updated systemd should be? How would I add the arguments "-useperfthreads -NoAsyncLoadingThread -UseMultithreadForDS"

You may not need force_install_dir, I'm not 100% sure. If yours doesn't work, you may have to add it in with your directory path or relocate your files to the same file structure I have.

And if you want to use the arguments, you just add them after the PalServer.sh in ExecStart. I found that the args lowered my server's FPS, but you will want to experiment yourself.

@travisrroy I think I broke something, I changed the file, now systemctl says no changes and removed my config. server is no longer up, I'll probably revert.... I'm really trying to wrap my head around this, I learned a bit about crontab and got that working and modified a few things to my liking, but this systemd stuff may be beyond me today. I just setup a on premise fusionPBX server at home and spent all day getting incoming and outgoing calls working so maybe I'm just burnt out.

Sometimes, if restart the service via a cronjob, the server will run, but the RCON process will not come up...
