Startup location

Chi Yi Lee — Tue, 08 Jun 2004 01:42:17 GMT

Hi
I made a script and planning to launch it when the system boot. Do I put the script in /sbin/init.d?
Do I need to edit somewhere?

thanks

Hello,

In /sbin/init.d you just place the startup or shutdown script , but you must tell the system how and when to use it .

You will tell the system to start the script in a certain execution level . This is defined in the /sbin/rcX.d . X means the execution level in which the script will be executed

In this directories you will create a file for the startup , SXXX..... , and a file for the shutdown KXX.... XXX means the order in which the scripts will be executed inside the execution level.

There are a lot of examples in this directories

XXX means the orede

hi,

Adding a program to start automatically at run time requires that the program be put in /sbin/init.d directory.
the execution scripts contains four major parts which are passed as command line arguments to these scripts.

start_msg displayed on the console when starting
stop_msg displayed on the console when stopping
start command to start the program
stop command to stop the program

and these are put in the configuration for each respective script at /etc/rc.config.d directory

next you need to decide at which run level you are going to start the script, say you are planning to start the script at run level 2. a link file has to be placed in /sbin/rc2.d directory.

ln -s /sbin/init.d/script /sbin/rc2.d/S900script

with best wishes
Naveej

Thanks Javier

One more Q.
It seems like in /sbin/rcX.d are bunch of links. Is that mean that I don't have to put my script in /sbin/init.d?

No... /sbin/init.d should contain the script, /sbin/rc#.d should contain symbolic links to that script.

Hi,

You must put your script in /sbin/init.d and create the link to /sbin/rcX.d directory.

Script has to be kept in /sbin/init.d directory whereas files under /sbin/rc?.d are links to the script in /sbin/init.d.

hi,

this is an example for what we do typically for Oracle Database startup:

Relevant Files:
===============
a. /sbin/init.d/oracle
contains the main script for doing db startup and shutdown owned by root

b. /etc/rc.config.d/oracle
this file enables/disables automatic startup and shutdown of the databases owned by root

c. /sbin/rc1.d/K100oracle ->/sbin/init.d/oracle
this link tells the system when to execute the Oracle script with the 'stop' command in single user mode during system shutdown

d. /sbin/rc2.d/S990oracle ->/sbin/init.d/oracle
this link tells the system when to execute the Oracle script with the 'start' command in multi-user mode during system startup

Steps:
======
1. Create an executable script /sbin/init.d/oracle for the startup and shutdown of Oracle

Your script should attempt to start the database with the following command:
su - -c <$ORACLE_HOME>/bin/dbstart

Your script should attempt to shut the database with the following command:
su - -c <$ORACLE_HOME>/bin/dbshut

Make sure that the script is owned and executable only by the super user.

2. Create the file /etc/rc.config.d/oracle
This file should contain:
ORACLE_START=1
export ORACLE_START

3. Edit /etc/oratab
ORACLE_SID:ORACLE_HOME:Y|N

where Y or N indicates whether you want the dbstart and dbshut scripts to be run

4. Make /sbin/rc1.d/K100oracle a symbolic link to /sbin/init.d/oracle

5. Make /sbin/rc2.d/S990oracle a symbolic link to /sbin/init.d/oracle

hope this helps!
