startup scripts

mas123 · 03-09-2009, 01:03 PM

Hello,
I want to run an executable c file on start up. Im using ubuntu. I read few how to on this topic, but things are not working so far. These are the steps i followed:
1. create myscript.sh in etc\init.d

myscript.sh
#run c file
./start

2. give the file permissions:
chmod +x myscript.sh
3. create a symbolic link in rc3.d:
sudo ln -s /etc/init.d/myscript.sh /etc/rc3.d/S500myscript.sh
sudo ln -s /etc/init.d/myscript.sh /etc/rc3.d/K001myscript.sh

Currently I am in runlevel 2, I switch to runlevel 3 by the following comman:
sudo init 3
I expect my c code to run..but this is not the case
I also tried this command:
sudo update-rc.d myscript.sh defaults

but no luck...any idea what i am missing?

Thank you inadvance,
MAS

#run c file

try to give the whole path to start or first cd to the directory which contains start

what about manually start your c file
#/etc/init.d/myscript.sh start, is this successfully start your c file? if yes check below mention things

did u check whether the startup script added on runlevel 3
#chkconfig --list | grep myscript.sh
or
#cd /etc/rc3.d, and check whether the script is exist or not

Try adding an echo command to your start.sh. That should tell you for a fact whether/not your start.sh is being invoked or not.

If not - you probably aren't supplying the path right!

initially, i had start in the etc\init.d folder
i cd to the directory which contains start:
cd /home/MAS/Desktop

I also included echo commands but things arent working yet

maually starting myscript.sh works

I cd to /etc/rc3.d and the soft link is there named S99MAS

I have a similar problem - I want to automatically start and stop Apache HTTP Server on Linpus.
I've added a script to /etc/init.d.
I've run chkconfig to add the service.
I've checked that the script exists in /etc/rc5.d (I'm assuming this is the relevant run level - executing runlevel just gives me "unknown" for some reason..?)
I can start and stop the service using:
service apache start
service apache stop

But when I reboot, the script doesn't run. Where do I go from here?
Thanks,
Bernie
