Installation d'Octoprint sur Orange PI PC Plus
Installation de l'Orange PI
Creation d'une carte SD
Télécharger la distribution linux armbian ubuntu server : [1]
décompresser l'archive,le fichier image doit être flasher sur une carte micro-sd de 8Go.
Plusieurs solution existe pour créer des sd à partir d'un fichier image. Sous Windows 10 on peut utiliser Etcher : [2]
Pour la documentation de création de carte micro-SD onpeut se reporter à la documentation armbian :[3]
Installation du système
Insérer la carte micro-sd dans l'Orange PI ATTENTION il est impératif que la carte Orange PI est accès à internet pour l'installation. Sinon l'orange PI rame et met des plombes à démarrer. La seule solution est de brancher un cable RJ45 sur l'Orange PI (est ilutile de préciser quele cable RJ45 doit lui même être relier à un routeur Internet ?). Ilest en théorie possible d'installer l'OrangePi àpartir de la console en utilisant une sonde de debug, manifestement le comportement n'est pas stable.
Démarrer l'Orange PI,le premier démarrage est relativement long (s'inquiéter apres 5 mn)
Déterminer l'adresse IP de l'Orange PI
Pour cela on utilise un scanner IP
AngryIP scanner par example
ou nmap sous linux
Connexion en ssh à l'orange PI
ssh root@<adresse de l'orange> par example ssh root@192.168.1.126 le mot de passe par defaut est 1234.
à la première connexion,l'orange demande un nouveau mot de passe root et la creation d'un utilisateur standard dans notre cas le mot de passe root à été changé en "freehumans" nous créons également l'utilisateur pi (mot de passe "raspberry") comme compte utilisateur
[lenovo.ADB-6b89cf] ? ssh root@192.168.1.126
root@192.168.1.126's password:
X11 forwarding request failed on channel 0
You are required to change your password immediately (root enforced)

Démarrage automatique d'octoprint
On recopie les fichiers de demarrage dans les repertoires /etc/init.d et /etc/default
pi@orangepipcplus:~/OctoPrint$ sudo cp ~/OctoPrint/scripts/octoprint.init /etc/init.d/octoprint pi@orangepipcplus:~/OctoPrint$ sudo cp ~/OctoPrint/scripts/octoprint.default /etc/default/octoprint
On marque les fichiers comme executable
pi@orangepipcplus:~/OctoPrint$ sudo chmod +x /etc/init.d/octoprint pi@orangepipcplus:~/OctoPrint$ sudo chmod +x /etc/default/octoprint
On demande au système de demarrer octoprint au démarrage
pi@orangepipcplus:~/OctoPrint$ sudo update-rc.d octoprint defaults
Création des droits pour redémarrer le système à partir d'octoprint
on cree le fichier octoprint-shutdown dans /etc/sudoers.d/ pour y mettre la commande "pi ALL=NOPASSWD: /sbin/shutdown"
pi@orangepipcplus:~/OctoPrint$ sudo nano /etc/sudoers.d/octoprint-shutdown
le contenu du fichier est le suivant
