一、為什麼要自架MQTT Sever

如果家裡、公司或學校要使用物聯網開發專案，或者控制家裡的物聯網設備，透過免費的MQTT SEVER，那應該....

就是單純做玩具而已，所以會建議安裝再一些微型的裝置上，例如樹梅派或小型主機，可以用無頭模式的，如果家裡有一台一直開機的伺服器，1883 port沒被占用的話，拿就拿來用吧

有關MQTT SEVER的教學....我自己有安裝使用，但是教學沒有比這一篇大大的好，我就直接摘錄連結了

Source

• mosquitto-2.0.7.tar.gz (319kB) (GPG signature)

• Git source code repository (github.com)

Older downloads are available at https://mosquitto.org/files/

Binary Installation

The binary packages listed below are supported by the Mosquitto project. In many cases Mosquitto is also available directly from official Linux/BSD distributions.

Windows

• mosquitto-2.0.7-install-windows-x64.exe (64-bit build, Windows Vista and up, built with Visual Studio Community 2019)

• mosquitto-2.0.7-install-windows-x32.exe (32-bit build, Windows Vista and up, built with Visual Studio Community 2019)

Older installers can be found at https://mosquitto.org/files/binary/.

See also README-windows.md after installing.

Mac

Mosquitto can be installed from the homebrew project. See brew.sh and then use brew install mosquitto

Linux distributions with snap support

• snap install mosquitto

Debian

• Mosquitto is now in Debian proper. There will be a short delay between a new release and it appearing in Debian as part of the normal Debian procedures.

• There are also Debian repositories provided by the mosquitto project, as described at https://mosquitto.org/2013/01/mosquitto-debian-repository

Raspberry Pi

Mosquitto is available through the main repository.

There are also Debian repositories provided by the mosquitto project, as described at https://mosquitto.org/2013/01/mosquitto-debian-repository/

Ubuntu

Mosquitto is available in the Ubuntu repositories so you can install as with any other package. If you are on an earlier version of Ubuntu or want a more recent version of mosquitto, add the mosquitto-dev PPA to your repositories list - see the link for details. mosquitto can then be installed from your package manager.

• sudo apt-add-repository ppa:mosquitto-dev/mosquitto-ppa

• sudo apt-get update

• 安裝完成後，到C:\Program Files\mosquitto

• 開啟readme.txt就會有以下說明

• 連線到 http://slproweb.com/products/Win32OpenSSL.html

• 下載對應的 Win64 OpenSSL 1.1.0* Light 檔案(我是64位元)，下載於C:\Program Files\mosquitto，並執行(確認資料夾裡有沒有)

  • • libssl-1_1.dll, libcrypto-1_1.dll or libssl-1_1-x64.dll, libcrypto-1_1-x64.dll

• 主要是要把mosquitto當成一個Service

安裝Win64 OpenSSL 1.1.0* Light

libmosquitto on Windows is currently compiled without thread support, so

neither of mosquitto_loop_start() nor "mosquitto_pub -l" are available.

A better solution that the old pthreads-win32 is being looked into, so support

will return in the future. If you need thread support, the code still supports

it just fine. Support has been dropped to simplify installation.

Dependencies

------------

* OpenSSL

    Link: http://slproweb.com/products/Win32OpenSSL.html

    Install "Win32 OpenSSL 1.1.0* Light" or "Win64 OpenSSL 1.1.0* Light"

    Required DLLs: libssl-1_1.dll, libcrypto-1_1.dll or libssl-1_1-x64.dll, libcrypto-1_1-x64.dll

Please ensure that the required DLLs are on the system path, or are in the same directory as

the mosquitto executable - usually C:\Program Files (x86)\mosquitto or C:\Program Files\mosquitto.

Windows Service

---------------

If you wish, mosquitto can be installed as a Windows service so you can

start/stop it from the control panel as well as running it as a normal

executable.

When running as a service, the configuration file used is mosquitto.conf in the

directory that you installed to.

If you want to install/uninstall mosquitto as a Windows service run from the

command line as follows:

C:\Program Files\mosquitto\mosquitto install

C:\Program Files\mosquitto\mosquitto uninstall

Logging

-------

If you use `log_dest file ...` in your configuration, the log file will be

created with security permissions for the current user only. If running as a

service, this means the SYSTEM user. You will only be able to view the log file

if you add permissions for yourself or whatever user you wish to view the logs.

以系統管理員身分開啟CMD

開啟防火牆設定，打開port 1883
