Hard boot of RedHat linux on x86

davidtcw · 01-11-2006, 10:36 AM

Hi,
I'm a newbie to Linux Redhat.
%uname -a
Linux oracle-test.med-eng.com 2.4.9-e.30smp #1 SMP Fri Nov 28 07:18:53 EST 2003 i686 unknown

The server was hard rebooted, but did not run any of the
startup scripts (bootstrap).
I see the files in /etc/init.d directory, but not sure which ones should be used.

How do I run them?
And how do I get them to run at startup?

Help!!!!

/etc/inittab defines how init scripts are used during the startup process. What makes you think none of the scripts were executed on boot?

Prior to the hard reboot, we had all the Oracle processes running on this box. After startup, none of these processes were running.
I needed to manually restart them. There's 6 init levels.

I'm going to reboot at the end of day today. Can you tell me is this is the correct procedure?

#init 6
#shutdown -r now
#reboot

There is no reason to use all three of those commands. I would ordinarily perform a simple 'shutdown -r now' or reboot (which do the same thing). The shutdown system automatically changes the runlevel for you.

Why the hard reboot (power off, power on) would not have run all 6 init levels? Is there a log file I can check?
Without specifying the command, init 6, I'm a little wary.

By the way, when I do a
# whereis init
init: /usr/src/linux-2.4.9-e.5/init /usr/src/linux-2.4/init /sbin/init /etc/init.d /usr/share/man/man8/init.8.gz

I assume, it's in /sbin/init ? Is that right?
