Since you shutdown the system, all running processes will be turned off.

Kind regards

Hello,

Normally your system should take care of that. You can have a look in the /etc/rc.d/rc0.d folder to check when (in what order) your services are shutting down. The higher the number, the later the service will stop. This is done so that dependent services get stopped before the service they depend on.

Kind regards,

Eric

Thnks for the reply. I can check it by
# vi /etc/rc.d/rc0.d

what you say If I a script may work

Code:

vi /root/auto_shutdown_script



#!/bin/bash



/etc/init.d/squid stop > /dev/null 2> /dev/null



if [ $? -eq 0 ]

then

shutdown -h now > /dev/null 2> /dev/null

fi







Step..2



crontab -e



* 19 * * * sh /root/auto_shutdown_script > /dev/null

While you shutting your system, All services running on the server will going to shutdown.

Just shutdown the system and forget everything.

EricTRA as you mentioned in your post You can have a look in the /etc/rc.d/rc0.d folder to check when (in what order) your services are shutting down. How can I check it ?
kindly just explain it
thanks

Hello,

Just do:

Code:

ls /etc/rc.d/rc0.d

You'll get a list of links to scripts in init.d beginning with either K (Kill) or S (Start). The initial letter is followed by a number which indicates the sequence in which the scripts will start. If beginning with K then the stop command will be passed to the script in init.d to which the link references. If beginning with an S then the start command will be passed.

Code:

K01dnsmasq -> ../init.d/dnsmasq

K01smartd -> ../init.d/smartd

K02avahi-daemon -> ../init.d/avahi-daemon

K02avahi-dnsconfd -> ../init.d/avahi-dnsconfd

K02NetworkManager -> ../init.d/NetworkManager

K02oddjobd -> ../init.d/oddjobd

K03yum-updatesd -> ../init.d/yum-updatesd

S00killall -> ../init.d/killall

S01halt -> ../init.d/halt

Above is a list of some of the links in a CentOS server. You'll see that dnsmasq and smartd get stopped (Kill) before avahi-daemon and so on. The scripts starting with S are there to kill remaining processes, remove lock files and some other actions before the system is halted. You can check the contents of either of the init.d script to see what they do exactly.

At this link you can find some more basic information about runlevels and init scripts.

Kind regards,

Eric
