Starting venv on reboot
February 13, 2024, 14:45
I am using my raspberry to run a discord bot and usually i ssh into it and run
source file/bin/activate
python file/main.py
i tried adding those commands to crontab hoping it'd work but it does not
@reboot source file/bin/activate &
@reboot python file/main.py
i am fairly new to this and i just followed youtube so far to set stuff up. anyone know how to get my main.py file running on reboot?
Did you sudo crontab -e editing the crontab?
yup
Then you run as root
Don't use sudo
this still opens a venv but it will not open it in the same terminal as the one you log into with ssh
oh nvm just read it properly
try changing what you add to
@reboot source file/bin/activate && python file/main.py
I don't think that will work, as crontab doesn't have any environment variables.
My solution is to create a bash script.
oh. would you be able to run this bash script in crontab then?
And bash can't use relative paths, you need to be in the correct directory or use absolute paths
Yes
go ahead with creating a bash script then
This article describe the situation https://ersanpreet.wordpress.com/2019/09/08/executing-python-script-via-crontab/
im trying out your method of creating a bash file with source and the python command in it
but that causes python errors for some reason
AYYYYYY WE GOT IT
apparently it couldnt read upto the cogs folder for some reason
went only until home/winikolo/
bruh even with that fixed nothing is happening when i run the bash off crontab wtf, but manually running it works?
Cd into your bot’s directory
Then, run python after cd into your main.py
Or simply specify the absolute path to all your files
Or learn how to use docker instead. It gives you a variety of different options such as autostart a container on startup and so on
+ docker is a great hard skill for your it future 😛
I fixed the python errors by absolute path, yes, but what i want is for the bash script that runs the virtual env + main.py file to start on reboot, manually when i run it as in './start_script.sh' it works but when using cron tab to run it on reboot, it doesnt work
Idk if theres a way to see what the errors crontab sees but idk tbh
Just make it via docker container
Sure ill see, thank you
