Installing a usable private screeps server on Raspberry Pi.

iron

Recently there was a patch that reduced tick degradation in servers without mongodb.

I've ran this for a few solid days on a Raspberry Pi 2 and am getting 1 tick per second, you could possibly get more on a Raspberry Pi 3 but obviously it depends on how intensive the scripts running are, and how many users are going to be on.

Anyway, here's how I set it up for those who want to try:

sudo apt-get update && sudo apt-get upgrade
sudo apt-get install -y npm build-essential tcl git nodejs g++
#if npm -v returns version < 8 do "curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -"
sudo npm i -g npm
sudo nano /etc/dphys-swapfile
# set CONF_SWAPSIZE = 1000, feel free to set it back after npm install screeps
sudo sudo /etc/init.d/dphys-swapfile restart
sudo adduser --disabled-password --gecos "" screeps
sudo su screeps
mkdir ~/screeps-server
cd ~/screeps-server
npm install isolated-vm
npm install screeps
# install any mods, auth, admin-utils, screepsmod-features # manual tick-rate is now part of admin-utils
npx screeps init
npx screeps start
^C # Control + C to quit screeps
exit # this just exits the screeps user
sudo nano /etc/systemd/system/screeps-server.service
# Copy this into the file
    [Unit]
    Description=Screeps Server (world)
    Wants=network-online.target
    After=network-online.target

    [Service]
    Type=simple
    WorkingDirectory=/home/screeps/screeps-server
    ExecStart=/home/screeps/world/node_modules/screeps/bin/screeps.js start
    User=screeps
    Group=screeps

    [Install]
    WantedBy=multi-user.target
sudo systemctl daemon-reload
sudo systemctl start screeps-server

Additional things to do while the screeps server is running:

sudo su screeps
cd ~/screeps-server
npx screeps cli
# wait for cli to load
setTickRate(1000)

Also, delete all the bots unless you need them.

This should give you a server that can handle 2~3 players without becoming incredibly slow.

A few notes:

Use a reasonable power supply, a weak PSU will cause the pi to reset if it gets under load... and possibly corrupt everything in the process.
Remember to back up your world a few times before killing the server and set routine backups.
I haven't tried this with CPU intensive scripts, it may suffer if you have a few users running intense scripts every tick.
