I'm using a Raspberry Pi 2 Model B running the latest Raspbian Stretch Lite 2018-11-13.

I built a program that communicates with a LoRa chip (SX1276) using SPI, gets some data from a temperature sensor and prints the temperature on the screen.

My program consists of only one executable (apart from wiringpi library).

I was searching for a tutorial to make my program a *.deb package. Using this tutorial I managed to build a lora.deb package.

When I installed my lora.deb package sudo dpkg -i lora.deb the executable just deployed in a directory.

How can I make that package automatically run the executable and also run it every time the system boots?

    Check out systemd service files. If your deb package contains a service file, and you add a postinstall script to your package, you can bring up a service after install automatically and on boot. – datUser Jan 12 at 20:48

    See here here for guides to writing systemd unit files, which will be used by systemd (which handles startup) to start your service. – novice Jan 13 at 1:00

change '/usr/bin/something' to '/directory/path/to/deployed/executable' below:

$ cat /etc/systemd/system/something.service

[Unit]
Description = Something Service
After = network.target

[Service]
ExecStart = /usr/bin/something

[Install]
WantedBy = multi-user.target

$ systemctl daemon-reload
$ systemctl enable something
$ systemctl start something
  • Thank you very much! Reading through all those sites and tutorials I came up to the solution for the whole method. First of all I need to add a myapp.service into my *.deb package, then I'll have to write a postinst script that will copy the myapp.service into the proper path and enable the service. I'm not quite sure if instead of a copy you just have to add the myapp.service into the *.deb package with the proper path. – MrBit Jan 13 at 12:39
  • This is nice but it answers the question only partially. Where does this .service file go in the .deb file? How is the service activated by the .deb? – Jerther Mar 11 at 16:11
