This tool allows you to manage any ARK: Survival Evolved linux server without having to remember long commands.
It provides a lot of features, to get the full list check the Commands section on the bottom of this page.

Pre-requisites

To install ARK Server Tools you must have already installed SteamCMD following this guide:

https://developer.valvesoftware.com/wiki/SteamCMD#Linux

We assume you have created the steam user to store steamcmd and your ARK server.

Requirements

To allow your ARK server to communicate with the outside you have to open some ports in your firewall:

iptables -I INPUT -p udp --dport 27016 -j ACCEPT
iptables -I INPUT -p tcp --dport 27016 -j ACCEPT
iptables -I INPUT -p udp --dport 7778 -j ACCEPT
iptables -I INPUT -p tcp --dport 7778 -j ACCEPT
iptables -I INPUT -p tcp --dport 32330 -j ACCEPT

NB: Change the ports according to the ones set in your arkmanager.cfg file.

Install ARK Server Tools

To install ARK Server Tools run this command:

curl -sL http://git.io/vtf5N | sudo bash -s steam

NB: You may want to change the bash -s parameter to fit your steam user if different from steam.

This will copy the arkmanager script and its daemon to the proper directories and will create an empty log directory in /var/log for ARK Server Tools.

Configuration

Stored in /etc/arkmanager/arkmanager.cfg you can find the variables needed to start the server, like the port numbers, the system environment variables and so on.

Also, in this file, you can specify any parameter you want to add to the startup command of ARK server.
These parameters must be prefixed by the ark_ string, some example could be:

ark_SessionName="My ARK server"
ark_MaxPlayers=50
ark_ServerPVE=False
ark_DifficultyOffset=1

Your session name may not contain special characters (eg. !![EU]!! Aw&some ARK) as it could break the startup command.
In this case you may want to comment out the ark_SessionName variable and define it inside your GameUserSettings.ini file instead.

You can override or add variables for a specific system user creating a file called .arkmanager.cfg in the home directory of the system user.

Install ARK Server

To install ARK Server just run this command as normal user:

arkmanager install
