Mosquitto from Source

Proven on:

12 (bookworm)

The required tools:

• apt install git build-essential autoconf cmake

Get the source:

• git clone https://github.com/eclipse/mosquitto.git

The prerequisites:

• apt install libc-ares-dev libwebsockets-dev libssl-dev xsltproc docbook-xsl libsystemd-dev libwrap0-dev openssl
• # cJSON
  • git clone https://github.com/DaveGamble/cJSON
  • cd cJSON
  • mkdir build
  • cd build
  • cmake ..
  • make
  • sudo make install
  • cd ../..
• # uthash / utlist
  • git clone https://github.com/troydhanson/uthash
  • cp uthash/src/* mosquitto/include
• # For testing
  • apt install python3-psutil
  • git clone https://gitlab.com/cunity/cunit.git
  • cd cunit
  • mkdir local-build
  • cd local-build
  • cmake ..
  • cmake --build .
  • sudo make install
  • cd ../..

Build it:

• cd mosquitto
• make

Test it:

• make test

or

• make check

Note: There are a fairly large number of tests that bring this to a grinding halt unless you comment them out. MUCH more research is needed...

24/1474 tests fail...

18 of those make the test procedure halt...

Install it:

• adduser mosquitto

• sudo make install

• cp /etc/mosquitto/mosquitto.conf.example /etc/mosquitto/mosquitto.conf

Enable it as a systemd service:

• sudo cp service/systemd/mosquitto.service.simple /etc/systemd/system/mosquitto.service

• sudo vi /etc/systemd/system/mosquitto.service

Fix the location in line 8.

The install step on Debian puts the executable in /usr/local/sbin not /usr/sbin

• sudo systemctl daemon-reload

• sudo systemctl restart mosquitto.service

To be done:

Configure it:

Default configuration works just fine like a default install from the repos...

Use it:

This is a very deep rabbit hole.
