Ubuntu Server 22.04 LTSにOctoPrintを導入-傾奇小屋

010_Ubuntu Server 22.04 LTSにOctoPrintを導入

概要

Ubuntu Server 22.04 LTSでOctoPrintを使うのが目的です。
OctoPrintにカメラ機能を連携させるため、MJPG-Streamerも動作させます。
デフォルトだと、OctoPrintは5000/tcp、MJPG-Streamerは8080/tcpで動きますが、ユーザビリティ向上のためにhaproxyをリバースプロキシ用途で使い、OctoPrintは「 http://IPアドレス」、MJPG-Streamerは「 http://IPアドレス/webcam 」でもアクセス出来るようにします。

前提

以下構成を前提にしています。
ハードウェアやソフトウェアのバージョンが異なると手順が異なる可能性があります。

Raspberry Pi 4 Model Bのメモリ8GBモデル
Raspberry Pi HQ Camera
Raspberry Pi HQ Camera用6 mm 広角レンズ
Ubuntu 22.04 LTS
OctoPrint 1.8.1
haproxy 2.4.14-1
mjpg-streamer v1.0.0

環境構築

Raspberry Pi HQ Cameraの認識

vcgencmd get_cameraの結果が、supported=1 detected=1になればカメラは正常に認識しています。それ以外はカメラが正常に認識していない状態です。

HQ Cameraの場合は、デフォルト状態ではカメラが認識しません。

username@ubuntu:~$ vcgencmd get_camera
supported=0 detected=0

HQ Cameraが認識するように設定を変更します。

username@ubuntu:~$ sudo vi /boot/firmware/config.txt

[all]セクションの設定を変更と追記。

[all]セクションにあるcamera_auto_detectの設定を無効にし、カメラの自動認識機能をオフにする。
～～～
camera_auto_detect=1
↓
camera_auto_detect=0
～～～

[all]セクションの末尾に以下を追記して、HQ Cameraが認識するように設定。
～～～
# Raspberry Pi HQ Camera
start_x=1
gpu_mem=256
～～～

カメラが認識している事を確認します。
supportedとdetectedがどちらも1になっていれば、正常に認識しています。

username@ubuntu:~$ vcgencmd get_camera
supported=1 detected=1

mjpg-streamerの導入

mjpg-streamerの導入に必要になるcmakeとlibjpeg9-dev、gcc、g++をインストールします。

username@ubuntu:~$ sudo apt-get install cmake libjpeg9-dev gcc g++

Ubuntuのインストール時に作成した一般ユーザのhomeディレクトリにインストールします。

username@ubuntu:~$ cd ~
username@ubuntu:~$ git clone https://github.com/jacksonliam/mjpg-streamer.git

Example #1:
 To open an UVC webcam "/dev/video1" and stream it via HTTP:
  ./mjpg_streamer -i "input_uvc.so -d /dev/video1" -o "output_http.so"
-----------------------------------------------------------------------
Example #2:
 To open an UVC webcam and stream via HTTP port 8090:

OctoPrintの導入

OctoPrintをインストールします。
OctoPrint 1.8.0以降はPython2では動作しないため、Python3が必要です。
一般ユーザのhomeディレクトリにインストールする場合の手順です。

username@ubuntu:~$ python3 --version
Python 3.10.4
username@ubuntu:~$ sudo apt install python3-pip python3-dev python3-venv libyaml-dev build-essential
username@ubuntu:~$ mkdir OctoPrint && cd OctoPrint

(venv) username@ubuntu:~/OctoPrint$ pip install octoprint

USB接続された3Dプリンターにフルアクセスするため、dialoutグループとttyグループに所属している必要があります。
Ubuntu Server 22.04 LTSの場合、デフォルトでdialoutグループには所属していたのでttyグループにのみ追加します。

(venv) username@ubuntu:~/OctoPrint$ sudo cat /etc/group|egrep "dialout|tty"
tty:x:5:
dialout:x:20:username
(venv) username@ubuntu:~/OctoPrint$ sudo usermod -a -G tty username
(venv) username@ubuntu:~/OctoPrint$ sudo cat /etc/group|egrep "dialout|tty"
tty:x:5:username
dialout:x:20:username

OctoPrintの手動起動をします。
systemdサービス化する前のテスト実行です。

haproxyの導入

haproxyをインストールします。

username@ubuntu:~$ sudo apt install haproxy

/etc/haproxy/haproxy.cfgの末尾に設定を追加。

username@ubuntu:~$ sudo vi /etc/haproxy/haproxy.cfg

globalセクション、defaultsセクションは変更せず、frontend public以降を追記しています。

手動で起動する事を確認する。
自動起動はインストールしたら最初から有効だったので、手動でhaproxyが起動するかを確認します。
もし、自動起動が有効でなかったらsudo systemctl enable haproxyで設定します。
