Добрый день.
Есть компьютер, задача которого выполнять только некую программу на java.
Для запуска написал простой скрипт:
root@BGGate:~# cat /etc/init.d/bggate
#! /bin/sh
### BEGIN INIT INFO
# Provides: bggate
# Required-Start: sshd
# Required-Stop:
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
### END INIT INFO
echo `date`: 0:$0 1:$1 2:$2 3:$3 4:$4 RL:`runlevel` >> /root/runlog
case "$1" in
start)
sudo -H -u root nohup /opt/jdk/bin/java -jar /opt/bggate/BGGate.jar 1>/root/log 2>&1 &
;;
stop)
pkill java
;;
status)
ps -f -C java
;;
restart)
$0 stop
$0 start
;;
*)
echo "Usage: /etc/init.d/bggate {start|stop|status|restart}"
exit 1
;;
esac
exit 0
Сделал, как и положено, update-rc.d bggate defaults.
Но скрипт запускается дважды (вывод из скрипта
echo `date`: 0:$0 1:$1 2:$2 3:$3 4:$4 RL:`runlevel` >> /root/runlog
):
root@BGGate:~# cat /root/runlog
Mon Sep 26 17:19:38 MSK 2016: 0:/etc/rc6.d/K20bggate 1:stop 2: 3: 4: RL:2 6
Mon Sep 26 17:20:14 MSK 2016: 0:/etc/rc2.d/S20bggate 1:start 2: 3: 4: RL:N 2
Mon Sep 26 17:22:15 MSK 2016: 0:/etc/rc2.d/S20bggate 1:start 2: 3: 4: RL:N 2
Просто спустя две минуты скрипт запускается еще раз.
Немного о системе:

Подскажите, пожалуйста, куда покопать, что еще указать?
