Autorun script #21

Closed gavspav closed 9 years ago

gavspav commented 9 years ago

Not an issue with the library but I'm struggling to run my script automatically on boot.

Perhaps it would be useful for people if anyone could help me nail it!

I currently have sudo node /myscript.js & in a script which gets executed via rc.local.

The script won't run - I'm guessing its something to do with permissions.

It also might have something to do with $path being initialized differently when run from rc.local I'd suggest using full path names.

Myself, I'm using this setup:

added to end of /etc/rc.local

start appliance

su -c /home/zefiro/bin/start_screen.sh zefiro

/home/zefiro/bin/start_screen.sh (which is chmod u+x)

!/bin/bash

cd /home/zefiro/prog/wodo-raspi-light screen -AdmS slave -t run screen -S slave -X screen -t edit1 screen -S slave -X screen -t edit2 screen -S slave -p run -X stuff $'sudo node ledstrip.js\n' screen -S slave -p edit1 -X stuff $'nano ledstrip.js \n'

I also set it such that when I log in, I'm directly put into this screen. Much easier for debugging (seing the console output).

You should have a look at pm2, which can do a lot of things (like monitoring your script, restart if it crashes, etc) and can also install the necessary files to run on system startup.
