=== Mono No More ===
EcoServer is compiled natively for Linux but requires some packages.
Prior to version 9.0 of Eco, it was required that you run with a very old build (no later than 5.14) of the Mono development libraries, and use Mono to run the server. This is no longer the case.
 
=== .NET Core Libraries ===
To install the required packages for Linux, use:<syntaxhighlight lang="bash">
Eco is now built with and is run leveraging [https://docs.microsoft.com/en-us/dotnet/core .NET Core], and runs as a native binary on Linux. You will have to [https://docs.microsoft.com/en-us/dotnet/core/install/linux install the .NET Core 3.1 libraries], repositories for which Microsoft makes available for several Linux distributions. Follow the directions on Microsoft's site for instructions for installing the libraries.
./install.sh

On an Asus router you can find these settings under Wan -> Virtual Server / Port Forwarding. ( I censored my own setup to keep my server secure but this should give some idea). First of all you need to set a name (Service name). The next item is the port range, on my router I would write 3000:3001 to give it the right range. Next item is the local IP - this should be your server IP. Leave the local port blank.

To safely shut down the Eco server, send SIGINT or press Control+C with the <tt>EcoServer</tt> process interactively to initiate a safe shutdown.
You can choose to create the service either system-wide OR as a user based service. The latter you CAN do without root but if you can't sudo/be root to use the loginctl command it won't stay around when you're logged out, and won't start on boot.
 
If you've visited this before, note the example service files have been changed to actually cleanly shutdown the Eco server!  The prior version of both examples in this Wiki would NOT correctly stop the server.
 
For system-wide setup you can do the following -- using your favorite editor (vi, nano etc.) edit /etc/systemd/system/EcoServer.service or /usr/lib/systemd/system/EcoServer.service (which depends on your platform, generally though /usr/lib/systemd is for installed packages, not local modifications) and paste the following making sure to update User, Group, WorkingDirectory, and ExecStart.
 
WorkingDirectory is going to be the root of your ECO server.  If you'd normally start on the command line from /games/Eco then WorkingDirectory should be /games/Eco

You can also deploy using a systemd user service which means you won't need root to start/stop/restart. You'll have to remove the User and Group lines from the unit, and if you want it to start on boot you'll need to enable that for the user.

Revision as of 17:24, 5 May 2022

Important Foreword

First, a disclaimer: Strange Loop Games does provide a Linux server build, but they do not offer official support for it at this time. It is provided as a convenience, not a product.

If you run into trouble or have a question, you can make inquiries in the #server-help channel in the Eco Discord server, but keep in mind the information above.

Prerequisites

EcoServer is compiled natively for Linux but requires some packages.

To install the required packages for Linux, use:

./install.sh

This will install the following packages:

Eco Dedicated Server files

There are two primary options for acquisition of the Eco dedicated server: getting it directly from Strange Loop Games, or through Valve Software's Steam platform.

Steam Command-Line Client

Getting SteamCMD

The ECO Dedicated Server is made available through Valve Software's Steam distribution system, and Valve provides a command-line tool called SteamCMD to facilitate command-line installation of products in various environments, including Linux. Follow the directions on the foregoing link to get the SteamCMD program installed and configured on your system. You will not need SteamCMD if you are acquiring the Eco Dedicated Server directly from Strange Loop Games.

Installing Eco with SteamCMD

Presuming for the same of simplicity that you wish to install the Eco Dedicated Server into an Eco subdirectory of your home directory, a script such as the following will install and subsequently update the software for you:

#!/bin/bash
steamcmd +force_install_dir ~/Eco +login anonymous +app_update 739590 -beta default validate +quit

SLG Direct Download

An archive of the current release of the Eco Dedicated Server as of this writing (Beta 9.4.1) can be found here. The following series of commands will download the archive, and set the Eco Dedicated Server up in an Eco subdirectory of your home directory, and save a copy of the install archive into a dist subdirectory of your home directory:

mkdir -p ~/Eco
cd ~/Eco
wget https://play.eco/s3/release/EcoServerLinux_v0.9.4.1-beta.zip
unzip EcoServerLinux_v0.9.4.1-beta.zip
mkdir -p ~/dist
mv EcoServerLinux_v0.9.4.1-beta.zip ~/dist/

Setting up the network

Setting up firewalld on your server

firewall-cmd --zone=public --add-port=3000/tcp --permanent
firewall-cmd --zone=public --add-port=3000/udp --permanent
firewall-cmd --zone=public --add-port=3001/tcp --permanent

systemctl restart firewalld

Forwarding your router ports

To give other people access to your server you need to tell your router how to handle incoming request from certain ports that come from an external computer.

On an Asus router you can find these settings under Wan -> Virtual Server / Port Forwarding. ( I censored my own setup to keep my server secure but this should give some idea). First of all you need to set a name (Service name). The next item is the port range, on my router I would write 3000:3001 to give it the right range. Next item is the local IP - this should be your server IP. Leave the local port blank.

Starting the Server

Because the Eco Dedicated Server is now a native Linux binary, starting it could not be easier. Again, presuming it is installed in an Eco subdirectory of your home:

cd ~/Eco
./EcoServer

Systemd service script

You can choose to create the service either system-wide OR as a user based service. The latter you CAN do without root but if you can't sudo/be root to use the loginctl command it won't stay around when you're logged out, and won't start on boot.

If you've visited this before, note the example service files have been changed to actually cleanly shutdown the Eco server! The prior version of both examples in this Wiki would NOT correctly stop the server.

For system-wide setup you can do the following -- using your favorite editor (vi, nano etc.) edit /etc/systemd/system/EcoServer.service or /usr/lib/systemd/system/EcoServer.service (which depends on your platform, generally though /usr/lib/systemd is for installed packages, not local modifications) and paste the following making sure to update User, Group, WorkingDirectory, and ExecStart.

WorkingDirectory is going to be the root of your ECO server. If you'd normally start on the command line from /games/Eco then WorkingDirectory should be /games/Eco

[Unit]
Description=Eco Server
# The below may or may not work correctly depending on platform, it's important that systemd is asked to start this after networking is online at the very least.
After=syslog.target network.target nss-lookup.target network-online.target

[Service]
Type=simple
Restart=on-failure
RestartSec=5
StartLimitInterval=60s
StartLimitBurst=3
User=ecoserver
Group=ecoserver
Environment="DOTNET_BUNDLE_EXTRACT_BASE_DIR=%h/.net"
WorkingDirectory=/home/ecoserver/Eco_server
# change to where your steamcmd exists if you want to automatically update on each restart.
#ExecStartPre=/home/ark/server/steamcmd +login anonymous +force_install_dir /home/ecoserver/Eco_server/ +app_update 739590 +quit
# ExecStart MUST be a full path!  IE starting with /
ExecStart=/home/ecoserver/Eco_server/EcoServer
ExecStop=kill -TERM $MAINPID
[Install]
WantedBy=multi-user.target

Then update the systemd service by running the following:

sudo systemctl daemon-reload

Enable the Systemd service:

sudo systemctl enable EcoServer

You can then optionally start, stop and check the status of the server with the following commands respectively:

sudo systemctl start EcoServer
sudo systemctl stop EcoServer
sudo systemctl status EcoServer

You can also deploy using a systemd user service which means you won't need root to start/stop/restart. You'll have to remove the User and Group lines from the unit, and if you want it to start on boot you'll need to enable that for the user.

As root or a user with sudo access (this step is critical when setting up the service as a user service if you do not want systemd to shut the server down every time you logout!!):

sudo loginctl enable-linger ecoserv

User based service unit example:

[Unit]
Description=Eco Server
# The below may or may not work correctly depending on platform, it's important that systemd is asked to start this after networking is online at the very least.
After=syslog.target network.target nss-lookup.target network-online.target

[Service]
Type=simple
Restart=on-failure
RestartSec=5
StartLimitInterval=60s
StartLimitBurst=3
Environment="DOTNET_BUNDLE_EXTRACT_BASE_DIR=%h/.net"
WorkingDirectory=%h/Eco_server
# change to where your steamcmd exists if you want to automatically update on each restart.
#ExecStartPre=/home/ark/server/steamcmd +login anonymous +force_install_dir %h/Eco_server/ +app_update 739590 +quit
# ExecStart MUST be a full path!  IE starting with /
ExecStart=%h/Eco_server/EcoServer
ExecStop=kill -TERM $MAINPID
[Install]
WantedBy=default.target

As the ecoserv user (or whatever user you choose) create the directory for the unit file(s) if it doesn't exist, and place the above unit file within that directory:

# creates the whole path if it doesn't exist
mkdir -p ~/.config/systemd/user/
# edit the file here ... ~/.config/systemd/user/EcoServer.service ... or whatever you name it, just as long as it ends in .service
systemctl --user daemon-reload
systemctl --user enable EcoServer
systemctl --user start EcoServer

Notice the --user flag to systemctl AND not using sudo. In a user service you can not set the User and Group, and the WantedBy target must be default.target so we remove/change those in the service file. As a user service you can also use %h instead of /home/ecoserv (or whatever) to reference the user home directory, systemd will expand that for us.

Debian/Ubuntu Version

[Unit]
Description=Westwoods Eco
Wants=network-online.target
After=syslog.target network.target nss-lookup.target network-online.target

[Service]
Restart=on-failure
RestartSec=5
StartLimitInterval=60s

ExecStop=kill -TERM $MAINPID
[Install]
WantedBy=multi-user.target


Stopping the Server

To safely shut down the Eco server, send SIGTERM (saves world), SIGINT (immediate stop! does not save the world!) or press Ctrl+C with the EcoServer process interactively to initiate a safe shutdown.

Please not that this procedure doesn't work with Eco versions prior to 9.0.0-beta.

Docker

There is a Docker version of the server as well. You can pull the latest stable version using:

docker pull strangeloopgames/eco-game-server:latest

You can also find additional builds here:

https://hub.docker.com/r/strangeloopgames/eco-game-server

You will need to make sure that the Docker container is exposing the ports and map them to ports on the host that are open in the hosts firewall and router.

Troubleshooting

Missing GDI library

You may sometimes get a crash on an attempted initial startup with an error resembling the following:

Failed to load server, Exception was Exception: DllNotFoundException Message:Unable to load shared library 'libgdiplus' or one of its dependencies.

The solution to this error state is to simply install the missing library. On a Debian-derived host this can be done with:

sudo apt install libgdiplus

Connecting remotely

You may find that your server does not show up in a list for people outside of your local network, even if you have set "PublicServer": true and have opened the appropriate ports in your router (and firewall if enabled on your linux machine).

If this happens, try clicking on the "+" symbol in the "Your Worlds" area, then adding in the external IP and port you used (probably 3000). Unfortunately, https://www.yougetsignal.com/tools/open-ports/ does _not_ accurately reflect one's ability to connect to the server.
