I have managed to get this running as a system service. Has been running consistently for over a week and can be seen on twitter @ https://twitter.com/ComputeHole.

what is needed to get this running as a system service on Ubuntu 19.04 (should be the same for any Linux system using systemd

Step 1.)

clone the GitHub repo

git clone https://github.com/BrianMitchL/weatherBot.git

Step 2.)

edit keys.py in your favorite text editor and fill in the required information

Step 3.)

create the following file

sudo nano /etc/systemd/system/weatherBot.service

with the following content


[Unit]
Description=weatherBot

[Service]
Type=simple
WorkingDirectory=/path/to/weatherBot/GitHub/clone
ExecStart=/usr/bin/python3 weatherBot.py weatherBot.conf

[Install]
WantedBy=multi-user.target

Step 4.)
after creating the file above run the following commands

sudo systemctl enable weatherBot.service

Your weatherBot will now run as a systemd service and start @ boot

sudo systemctl start weatherBot.service

Your weatherBot is now running as a systemd service " weatherBot.service"

you can check the status by running

sudo systemctl status weatherBot.service

if changes are made the configuration of weatherBot you will have to reload the service for changes to be noticed

sudo systemctl daemon-reload

Step 5.)

????

Step 6.)

Profit.

I would have created a P/R but I wasn't sure how to go about adding the information correctly.

Also one benefit of this is it doesn't require the installation of any additional software to make use of this great project!!

This is great, thanks! I'll add some docs in the next few days.

might I suggest adding the different way to deploy weatherBot as separate Wiki pages? And then link to them in the README.md so it doesn't overly long?

Good suggestion, thanks! I moved the existing examples over and will work on adapting the systemd example you have above tomorrow.

No problem. Thanks for this project! Also let me know if you need anymore information and I'll do my best to provide it.

I added a systemd page to the wiki based off your example: https://github.com/BrianMitchL/weatherBot/wiki/Deploy---systemd Feel free to open a new issue or comment here if you think anything needs changing!

also from my experience this is true but it also extends to the actual weatherBot configuration files to, i.e. say you change the #hashtag that's tweeted, you'll have to do a daemon-reload or reboot the system

If changes are made to the weatherBot.service file, you will need to reload the service for changes to take effect.

systemd doesn't care about files that are passed read by weatherBot, so restarting weatherBot (stopping and starting the service) would be enough. I haven't tested in a while thought, so I could totally be wrong.
