LINUX – Create debian sysvinit startup script

Copy below content to a new file under /etc/init.d/_YOUR_SERVICE_NAME_

#!/bin/sh
### BEGIN INIT INFO
# Provides: <_YOUR_SERVICE_NAME_>
# Required-Start: $local_fs $network $named $time $syslog
# Required-Stop: $local_fs $network $named $time $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Description: <DESCRIPTION>
### END INIT INFO
SCRIPT=<COMMAND>
RUNAS=<USERNAME>
NAME=<_YOUR_SERVICE_NAME_>
PIDFILE=/var/run/$NAME.pid
LOGFILE=/var/log/$NAME.log
start() {
if [ -f $PIDFILE ] && kill -0 $(cat $PIDFILE); then
echo 'Service already running' >&2
return 1
fi
echo 'Starting service…' >&2
local CMD="$SCRIPT &> \"$LOGFILE\" & echo \$!"
su -c "$CMD" $RUNAS > "$PIDFILE"
echo 'Service started' >&2
}
stop() {
if [ ! -f "$PIDFILE" ] || ! kill -0 $(cat "$PIDFILE"); then
echo 'Service not running' >&2
return 1
fi
echo 'Stopping service…' >&2
kill -15 $(cat "$PIDFILE") && rm -f "$PIDFILE"
echo 'Service stopped' >&2
}
uninstall() {
echo -n "Are you really sure you want to uninstall this service? That cannot be undone. [yes|No] "
local SURE
read SURE
if [ "$SURE" = "yes" ]; then
stop
rm -f "$PIDFILE"
echo "Notice: log file was not removed: '$LOGFILE'" >&2
update-rc.d -f <NAME> remove
rm -fv "$0"
fi
}
status() {
printf "%-50s" "Checking $NAME..."
if [ -f $PIDFILE ]; then
PID=$(cat $PIDFILE)
if [ -z "$(ps axf | grep ${PID} | grep -v grep)" ]; then
printf "%s\n" "The process appears to be dead but pidfile still exists"
else
echo "Running, the PID is $PID"
fi
else
printf "%s\n" "Service not running"
fi
}
case "$1" in
start)
start
;;
stop)
stop
;;
status)
status
;;
uninstall)
uninstall
;;
restart)
stop
start
;;
*)
echo "Usage: $0 {start|stop|status|restart|uninstall}"
esac

then change those lines:

# Provides: <_YOUR_SERVICE_NAME_>
# Description: <DESCRIPTION>
SCRIPT=<COMMAND>
RUNAS=<USERNAME>
NAME=<_YOUR_SERVICE_NAME_>

to match your service

Next make the file executable:

chown +x /etc/init.d/_YOUR_SERVICE_NAME_

Install the service:

update-rc.d _YOUR_SERVICE_NAME_ defaults
