Valheim beta is regularly updated, this goes for both server and client. The client is usually updated automatically via Steeam, however the dedicated server is not. When the versions mismatch, ie: the server is behind; clients can no longer connect to the server.
Updating the server to the latest beta is easy, yet manual. I've written a few scripts to take care of this process. It could be improved in many ways, but it works so why bother.
Note: This procedure requires steamcmd
1) Create a start-script for Valheim, mine is called
valheim.sh and is placed with the binary:
#!/bin/sh export templdpath=$LD_LIBRARY_PATH export LD_LIBRARY_PATH=./linux64:$LD_LIBRARY_PATH export SteamAppID=892970 echo "Starting server PRESS CTRL-C to exit" ./valheim_server.x86_64 -name "valheim" -port 12345 -nographics -batchmode -world "worldname>" -password "password" -public 1 export LD_LIBRARY_PATH=$templdpath
2) Start a screen named
valheim by running
screen -S valheim
valheim.sh to start the dedicated server and detach from the screen
4) Create a new script called
valheim_nightly_update.sh with the following content:
#!/bin/bash VALSCREEN=valheim echo "Sending Control+C to $VALSCREEN" screen -S $VALSCREEN -X stuff $'�03' echo "Sleeping 10 seconds, let Valheim server shut down..." sleep 10 echo "Sleep done" echo "Running update check and install..." /bin/bash /home/aners/valheim/InstallUpdate.sh echo "Update check and install complete, sleeping 5 seconds" sleep 5 echo "Starting Valheim-server" screen -S valheim -X stuff 'sh /home/aners/valheim/valheim.sh'`echo -ne '�15'`
5) Create a crontab for the script with a runtime of your chosing
Mine looks like this:
# m h dom mon dow command 0 5 * * * /bin/bash /home/aners/valheim_nightly_update.sh
Every morning, my Valheim server is stopped, updated and restarted.
