Installation Octorint auf Ubuntu 22.04 LTS

Als erstes system Aktualisieren
sudo apt update && sudo apt upgrade
Pyton version überprüfen
python3 -V
Wenn Pyton nicht instaliert ist mit
sudo apt install python3
instalieren.
Folgende Python dependencies werden benötigt

sudo apt install python3-pip
sudo apt install python3-dev
sudo apt install python3-setuptools
sudo apt install python3-venv
sudo apt install git
sudo apt install libyaml-dev
sudo apt install build-essential
Checken ob alles up to date ist pip install pip –upgrade # minu minus upgrade
Ermitteln der IP Adresse: hostname -I

Jetz muss ein neuer User erstellt werden:
Als Beispiel: octo
sudo useradd -m octo
Password (Beispiel)
sudo passwd octo yourpassword
Gruppen zum User Hinzufügen
sudo usermod -a -G tty,dialout octo
User octo anmelden:

su octo
cd ~
cd /home/octo
mkdir OctoPrint && cd OctoPrint

Anlegen des virtual environment:
python3 -m venv venv

Achtung space zwischen den Punkten
. ./venv/bin/activate
pip install –no-cache-dir octoprint #install minu minus

Test der Insallation
su octo
cd ~
cd /home/octo
python3 -m venv venv
. ./venv/bin/activate
~/OctoPrint/venv/bin/octoprint serve
Start OctoPrint user Interface
localhost:5000




Vorbereitung zum Autostart von OctoPrint
Datei erstellen -> octoprint.default

# Configuration for /etc/init.d/octoprint

# The init.d script will only run if this variable non-empty.
OCTOPRINT_USER=octo

# base directory to use
#BASEDIR=/home/octo/.octoprint

# configuration file to use
#CONFIGFILE=/home/octo/.octoprint/config.yaml

# On what port to run daemon, default is 5000
PORT=5000

# Path to the OctoPrint executable, you need to set this to match your installation!
#DAEMON=/home/octo/OctoPrint/venv/bin/octoprint

# What arguments to pass to octoprint, usually no need to touch this
DAEMON_ARGS="--port=$PORT"

# Umask of files octoprint generates, Change this to 000 if running octoprint as its own, separate user
UMASK=022

# Process priority, 0 here will result in a priority 20 process.
# -2 ensures Octoprint has a slight priority over user processes.
NICELEVEL=-2

# Should we run at startup?
START=yes
