小狐狸事務所: 樹莓派學習筆記 : 編譯 MQTT 套件 mosquitto 原始碼問題

今天繼續讀朱克剛寫的 "AIOT與OpenCV實戰應用：Python、樹莓派、物聯網與機器視覺" 的 MQTT 部分, 書中使用的是 mosquitto 套件, 可用 pip 安裝或從 GitHub 下載原始碼自行編譯, 作者建議自行編譯, 因為可以開啟 websockets 功能以便透過網頁介面進行 MQTT 操作.

我照作者建議下載原始碼自行編譯, 但編譯過程發生錯誤, 試圖爬文解決未果, 暫且將過程記錄如下, 等待找到解決方案再來重新編譯, mosquitto 套件原始碼下載網址如下 :

# https://github.com/eclipse/mosquitto

開啟樹莓派的 Chromium 瀏覽器連線上面的 GitHub 網址下載原始碼 zip 壓縮檔 :

下載的壓縮檔 mosquitto-master.zip 預設放在使用者目錄下的 Downloads 資料夾下面, 可使用 unzip 程式解壓縮, 它會建立 mosquitto-master 子目錄來存放這些原始碼 :

pi@raspberrypi:~ $ cd Downloads

pi@raspberrypi:~/Downloads $ unzip mosquitto-master.zip

pi@raspberrypi:~/Downloads $ cd mosquitto-master

1. 編輯 config.mk 檔開啟 websockets 功能 :

用 nano 編輯 config.mk 檔, 將其中的 WITH_WEBSOCKETS 從原先的 no 改成 yes :

pi@raspberrypi:~/Downloads/mosquitto-master $ nano config.mk

這就是自行編譯的好處 : 能在編譯前進行細部功能設定.

2. 更新套件清單 :

此步驟是必要的, 否則後續下載安裝五套件時可能會因為找不到套件而安裝失敗 :

sudo apt-get update

pi@raspberrypi:~/Downloads/mosquitto-master $ sudo apt-get update

下載:1 http://archive.raspberrypi.org/debian stretch InRelease [25.3 kB]

下載:2 http://archive.raspberrypi.org/debian stretch/main armhf Packages [192 kB]

下載:3 http://raspbian.raspberrypi.org/raspbian stretch InRelease [15.0 kB]

下載:4 http://raspbian.raspberrypi.org/raspbian stretch/main armhf Packages [11.7 MB]

下載:5 http://archive.raspberrypi.org/debian stretch/ui armhf Packages [44.6 kB]

下載:6 http://raspbian.raspberrypi.org/raspbian stretch/non-free armhf Packages [98.9 kB]

取得 12.0 MB 用了 20min 48s (9,640 B/s)

3. 安裝五套件 :

此五套件是支援 MQTT 協定的函式庫 :

sudo apt-get install libc-ares-dev libwebsockets-dev libssl-dev xsltproc docbook-xsl

pi@raspberrypi:~/Downloads/mosquitto-master $ sudo apt-get install libc-ares-dev libwebsockets-dev libssl-dev xsltproc docbook-xsl

正在讀取套件清單... 完成

正在重建相依關係

正在讀取狀態資料... 完成

下列的額外套件將被安裝：

docbook-xml libev-dev libev4 libssl-doc libssl1.1 libuv1-dev libwebsockets8

sgml-data

建議套件：

docbook docbook-dsssl docbook-defguide dbtoepub docbook-xsl-doc-html

| docbook-xsl-doc-pdf | docbook-xsl-doc-text | docbook-xsl-doc

docbook-xsl-saxon fop libsaxon-java libxalan2-java libxslthl-java xalan

perlsgml w3-recs opensp libxml2-utils

下列【新】套件將會被安裝：

docbook-xml docbook-xsl libc-ares-dev libev-dev libev4 libssl-dev libssl-doc

libuv1-dev libwebsockets-dev libwebsockets8 sgml-data xsltproc

下列套件將會被升級：

libssl1.1

升級 1 個，新安裝 12 個，移除 0 個，有 335 個未被升級。

需要下載 4,105 kB/6,264 kB 的套件檔。

此操作完成之後，會多佔用 30.5 MB 的磁碟空間。

編譯中出現 "Incompatible database configuration" 與 "fatal error: cjson/cJSON.h: 沒有此一檔案或目錄" 等錯誤訊息, 有空再查原因.

如果 make -j4 編譯沒有錯誤, 後續還有兩個安裝指令 :

$ sudo make install (安裝)

$ sudo ldconfig

5. 建立 mosquitto 目錄 :

$ sudo mkdir /var/lib/mosquitto

6. 編輯 mosquitto 設定檔 :

$ sudo nano /etc/mosquitto/mosquitto.conf

輸入如下內容 :

port 1883

listener 9001

protocol websockets

pid_file /var/run/mosquitto.pid

persistence true

persistence_location /var/lib/mosquitto/

7. 建立執行 mosquitto 的帳號 :

一直按 Enter 即可, 密碼可任填 :

$ sudo adduser --shell /usr/sbin/nologin --no-create-home mosquitto

8. 編輯服務檔 :

$ sudo nano /etc/systemd/system/mosquitto.service

輸入內容如下 :

[Unit]

Description=Mosquitto MQTT Broker Deamon

ConditionPathExists=/etc/mosquitto/mosquitto.conf

After=network.target

[Service]

Type=forking

RemainAfterExit=no

StartLimitInterval=0

ExecStart=/bin/sh/ -c "/usr/local/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf -d"

ExecReload=/bin/kill -HUB $MAINPID
