On an amazon linux instance, I have two scripts called
stop_my_app which start and stop forever (which in turn runs my node.js app). I use these scripts to manually start and stop my node app. So far so good.
My problem: I also want to set it up such that
start_my_app is run whenever the system boots up. I know that I need to add a file inside
init.d and I know how to symlink it to the proper directory within
rc.d, but can't figure out what actually needs to go inside the file that I place in
init.d. I'm thinking it should be just one line, like,
start_my_app, but that hasn't been working for me.
In the file you put in
/etc/init.d/ you have to set it executable with:
chmod +x /etc/init.d/start_my_app
Thanks to @meetamit, if this does not run you have to create a symlink to
ln -s /etc/init.d/start_my_app /etc/rc.d/
Please note that on latest Debian, this will not work as your script have to be LSB compliant (provide, at least, the following actions: start, stop, restart, force-reload, and status): https://wiki.debian.org/LSBInitScripts
As a note, you should put the absolute path of your script instead of a relative one, it may solves unexpected issues:
And don't forget to add on top of that file:
Set a crontab for this
#crontab -e @reboot /home/user/test.sh
after every startup it will run the test script.
