Hallo zusammen,
ich habe gerade ein kleines Problem. Ich habe unseren MinecraftServer im Autostart von unserem VServer.
Der Autostart und das Script funktionieren auch wunderbar. Hier das Script für den Autostart und die Steuerung.

exit 0Jetzt haben wir aufgrund unserer Modvielfall das Problem das der Server gerne mal crasht, was jetzt nicht so dramatisch ist wenn ich zuhause bin, weil kann ich ja neustarten. Das Problem ist wenn ich nicht zuhause bin ist der Server offline. Also habe ich ein 2. Script, welches sich aber nur mit dem Nutzerselber ausführen lässt (Im Moment).
Bash
#!/bin/sh
while true
do
java -Xmx6144M -Xms6144M -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalPacing -XX:ParallelGCThreads=2 -XX:PermSize=256M -jar FTBServer-1.6.4-965.jar -nogui
echo "If you want to completely stop the server process now, press Ctrl+C before
the time is up!"
echo "Rebooting in:"
for i in 5 4 3 2 1
do
echo "$i..."
sleep 1
done
echo "Rebooting now!"
doneDie Startdatei öffnet das Script, das Problem: Wenn ich den Server über den ersten Code nun stoppen will startet der den Server auch neu, was ein bisschen ungünstig ist falls ich den Server mal wirklich stoppen will. Und Killen will ich den Prozess nicht einfach, weil das nicht alle User können.
Ich versuche gerade die beiden Scripts zu einem zu machen, gelingt mit auch soweit das ich den Server mit der "Neustart-Funktion" starten kann. Aber beim Stoppen will ich den ja nicht neustarten.
Ich bin gerade etwas damit überfordert das erste Script so umzubauen das der Server auch wirklich gestoppt wird.
Habt ihr eine Idee wie ich das bewerkstelligen kann.
Danke und Gruß ASJoker.
