Question

Start service on boot under CentOS, how?

Asked by: dcrudo

Dear Experts,

I'm not very familiar with linux...but I try to get around a little bit :)

I need to load automatically a driver before anoter driver is loaded, how can I do it?

The driver is mISDN and I need to load it with:

/etc/init.d/misdn-init start

and I need to load it before 'asterisk' is loaded.

for your info, asterisk is configured as follow with chkconfig:

[root@localhost ~]# chkconfig --list asterisk
asterisk        0:off   1:off   2:on    3:on    4:on    5:on    6:off

what is the next step?

Thx a lot!

Dave.

in the rc.d scripts, where does asterisk start at?  It should be a s#_asterisk or something like that, the driver should have an s# before the one for asterisk.  I believe you have an rc file for each run level.

Hello,

I have S40_asterisk in directories:

rc2.d
rc3.d
rc4.d
rc5.d

In the directory /etc/ there are some files called
rc
rc.local
rc.sysinit

but no one of them has anything related to the launch of asterisk... do I have to just add an additional script in directories rc*.d ?

if yes... why are the same files in 4 different directories?

Thank you!

there are several different runlevels in linux  , for example rc5.d = run level 5, rc3.d = run level 3
run level 5 is graphical boot, run level 3 is text only, run level 6 is reboot, etc...

you can check which run level you are in by looking at your /etc/inittab file
id:5:initdefault

now your chkconfig shows asterisk running on run levels 2,3,4,5  this corresponds to the S40_asterisk in rc2.d - rc5.d
if you did a chkconfig --level 35 asterisk off, it would remove the S40_asterisk link in rc3.d and rc5.d
i'm guessing that misdn may have registered itself in chkconfig so you can do a chkconfig --list to see all of your services
if you don't see it, simply link your script to any file in the run level you want which has a file name < S40_asterisk
for example
S39_misdn would run before S40
