start
stop
The command can be called by hand to start or stop a specific service. In order to start a service automatically
during system boot, a link to the script has to be created in the
/etc/rc.d
directory. See chapter
[
I
for the link creation procedure.
For your demo application, create a new script at
/etc/init.d/myapp
on the target system:
root@vincell:~# nano /etc/init.d/myapp
Change the contents of this file as follows:
#!/bin/sh
### BEGIN INIT INFO
# Provides:
myapp
# Required-Start:
$all <what ever my be needed>
# Required-Stop:
# Default-Start:

# Default-Stop:

# Short-Description: Start myapp at boot time
# Description:
### END INIT INFO

export DISPLAY=:0
case "$1" in

# We don't want this script to block the rest of the boot process
