Boot Script

jhayes · 07-14-2003, 05:17 PM

hello i have a script i want to start when the server boots. i put the script on the /etc/rc.d/rc.local is this the right place? for some reason it doesn't run the script at boot.

any ideas,

i am running linux red hat 8.0

thanks,

jh

That is usually the file to place them in but I believe it depends on what runlevel you startup in, as Redhat changes these around, could be in /etc/rc.d/init.d or so forth. I no longer use Redhat, but sometimes they will have a link to each runlevel in /etc/ named like rc.0 or rc.3 and so forth. If you boot into runlevel 3, place the script where the link /etc/rc.3 is linked to.

/etc/rc.d/rc.local is a good place. But if it's a script, it may be better to put it to /etc/rc.d/init.d/ and symplnk it to the right runlevel (for example /etc/init.d/rc3.d/S50yourservice). 'rc3.d' means it's runlevel 3 (console, multiuser, with network), 'S50' means to start the service (S), numbers are priorities.

...and if you're still wondering why it didn't work while you had in incorporated in rc.local, debugging shouldn't be hard if you make it a separate script and do "sh -x <script> (args) 2>&1|tee /tmp/script.log", then read /tmp/script.log if it did fly by to fast.
Else post the script(+log).

sorry kind of a newbie,
i have the script called startup.sh , how would i add this to the /etc/initd/rc3.d/ ?

thanks

/etc/rc.d/init.d/ directory, simply copy your script inside. Then you need to create a symplnik from this file (copied). The symplink should be placed in the right directory /etc/rc?.d/

okay i copied the script to the folder /etc/rc.d/init.d,

how do i create the symplnik though? once created do i put it in /etc/rc3.d?

thanks, and sorry for the questions.

Just:

ln -s /etc/rc.d/init.d/startup.sh /etc/rc.d/rc3.d/S50startup

COOL I'LL GIVE THIS A TRY AND LET YOU GUYS KNOW HOW IT WORKS.

jhayes · 07-15-2003, 10:43 AM

no luck, it didn't start. i had to run the script manually. is there a was to test it, without having to reboot? does anyone know how i can troubleshoot this?

thanks,

You know, it was my mistake. The rigth path is:

ln -s /etc/rc.d/init.d/startup.sh /etc/rc3.d/S50startup

jhayes · 07-15-2003, 12:08 PM

somehow it got created in the /etc/rc3.d/ directory. because i have it in both the /etc/rc.d/rc3.d and in /etc/rc3.d. and i did a diff on both and there is no differences.

any ideas,

thanks

Yes, it was created in both folders because the /etc/rcX.d are symbolic links to the real ones /etc/rc.d/rcX.d

It's weird that the script doesn't execute when booting in text mode (level 3).

If you go to /etc/rc.d/init.d and you try to execute the script like:

./startup.sh

Does it executes normally??
