6. Change PASSWORDS and CHANGE ME AREAS before launching.

  • sudo vi build_dedicated_valheim_server.sh

#There are 4 things you need to change!
#Note: Minimum password length is 5 characters & Password cant be in the server name.

  • userpassword=”user_password” <—password for the new Linux User it creates
  • password=”passw0rd” <—password for the Valheim Server Access
  • displayname=”server display name” <—Public display name for server
  • worldname=”111111111″ <—local inside world name

#Save the file

11. Stop Valheim service.

I love two things in life, games and sports. Although sports were my earliest interest, it was video games that got me completely addicted (in a good way). My first game was Crash Bandicoot (PS1) from the legendary studio Naughty Dog back in 1996. I turned my passion for gaming into a job back in 2019 when I transformed my geek blog (Re-actor) into the gaming website it is today.

  1. Hmm, I’m stuck on step 5. I get this error.

    “chmod: cannot access ‘build_dedicated_valheim_server.sh’: No such file or directory”
    and when I look in that directory, this is all that’s in there…
    “advancemenu.sh CODE_OF_CONDUCT.md LICENSE menu.sh README.md
    “

  2. Not getting any connectivity. This VM also (until v recently) hosted a Minecraft server, so I know it’s connectable and how to set these things up… UFW has been configured and even disabled. The service appears to be running but just getting nothing on the client side at all, no indication that any game server is running.

  5. Hello everyone,
    it all went well so far. But when I try to copy our existing world it says no permission on /home/steam/.config/unity3d/IronGate/Valheim/Worlds as I am not the owner. When I try to log in into Ubuntu with steam and the password I’ve edited in the script file it doesn’t let me log in. I am new to linux, sorry

    • You could make another user and upload it to this users home directory (via sftp or whatever you like)

      Step 1: Upload file.
      Step 2: (As sudo) Move file to /home/steam/.config/unity3d/IronGate/Valheim/Worlds/
      Step 3: (As sudo) Change the ownership of the file to steam:steam with ->
      sudo chown steam:steam filepath

  6. When executing the install script and steamcmd is being run in the process of the script execution I get the following steamcmd error:

    “ERROR! Failed to install app ‘896660’ (Disk write failure)”

    (Yes, there’s more than enough free disk space on / )

    🙁

  7. I think that

    sudo systemctl stop valheim.service

    should read

    sudo systemctl stop valheimserver.service

    Otherwise you get “Failed to stop valheim.service: Unit valheim.service not loaded.”

  10. valheimserver.service: Service has more than one ExecStart= setting, which is only allowed for Type=oneshot services. Refusing.

    • you must use a launch modifier until STEAM and Valheim fix whatever server listing system they have.

      use the following +connect IPADRESSofyourserver:PORT
      You do this by right clicking the Valheim game icon within Steam, select properties and type your server information. close it and launch the game.
