How to install

From this tutorial a script was created. Same prerequisets are applied:

• Stable internet connection;
• Configurable router that permits you to expose ports;
• Dedicated machine or virtual machine running Ubuntu 20.04 either Desktop or Server(Recommended);

There are two main files:

• install.sh
• uninstall.sh

ATTENTION! Both scripts were designed to run under root or super user via sudo command, mostly because you can see in the tutorial that a lot of commands need privileges to install. Also you can see that the user is valheim(not steam), with home directory /opt/valheim and data folder /var/lib/valheim.

How to install

sudo ./install.sh

This command will use the default configuration and will generate a random password. If you want to configure it, you can run with --help to check available options:

sudo ./install.sh --help

Output:

This is an install bash script for a Valheim Server.

Syntax: ./install.sh [-h|n|p|pb|wn|pw]
options:
-h |--help
  Print help.
-n |--name
  Set the server name - Default: "My Valheim Server"
-p |--port
  Set the server port - Default: 2456
-pb|--public
  Set the server port - Default: 1
-wn|--world-name
  Set the world name - Default: "Dedicated"
-pw|--password
  Set the password - Default: <random_16> NOTE: this will pe printed and saved in a file.

Sample:

sudo ./install.sh -n 'Test Server' -p 2459 -pb 0 -wn 'TestWorld' -pw 'TestPassword098'

NOTE! I'd recommend not adding the password, because the generated one is secure enough. It is actually recommended actually to change the password once in a while on the /opt/valheim/start_valheim_server.sh script.

How to uninstall

Just run the script:

sudo ./unistall.sh

Output:

[INFO] - Checking if there is a service.
[INFO] - Found service! Attempting to remove it before uninstall...
Removed /etc/systemd/system/multi-user.target.wants/valheim-server.service.
userdel: valheim mail spool (/var/mail/valheim) not found
[SUCC] - Finished uninstalling!

THE END
