= SysVinit-Skripte für Linux =

== Anweisungen ==

Getestet auf Debian 5. Ändert die Benutzer-ID auf den Benutzer „opensim“. Unterstützt: start, stop, restart, status.

Zum Implementieren: Tippe: `cat > /etc/init.d/opensim` Füge das Skript von dieser Seite ein Drücke: `CTRL+D` Tippe: `chmod +x /etc/init.d/opensim` Das Skript sollte nun auf dem Server vorhanden und ausführbar sein.

Ändere den Header im Skript, um ihn an deinen Installationsordner und Benutzer anzupassen.

== Aktualisiertes Skript ==

Im Gegensatz zu Tedds Originalskript unten verlässt sich dieses Skript auf die eigene PID-Funktion von OpenSimulator, daher musst du die PIDFile-Einträge im Abschnitt [Startup] von OpenSim.ini/Robust.ini auskommentieren und auf `/tmp/OpenSim.exe.pid` und `/tmp/Robust.exe.pid` setzen, je nach Bedarf.

Dies ermöglicht es uns, das Skript zu vereinfachen und eine bessere Fehlerberichterstattung zu erhalten. Ein sauberes Herunterfahren von OpenSimulator wurde ebenfalls implementiert.

Die Verzögerung zwischen dem Versuch, OpenSimulator sauber herunterzufahren und einem erzwungenen Herunterfahren wurde auf 20 Sekunden verdoppelt. In einigen Fällen könnte dies jedoch immer noch nicht ausreichen. In Zukunft wäre es besser, den Status abzufragen.

Dieses Skript wird unter https://github.com/justincc/opensimulator-tools/blob/master/infrastructure/control/init.d/src/opensim gepflegt. Pull Requests sind willkommen!

'''Anmerkungen'''
* Sollte auf CentOS 7.x, CentOS 8.x, RHEL 7.x, RHEL 8.x funktionieren. Möglicherweise funktioniert es auch auf anderen Redhat-basierten Distributionen.
* Die Option "--server" legt die Standard-Garbage-Collection in Mono fest, was möglicherweise für den Produktionseinsatz etwas schneller ist. Die Verwendung von "--desktop" sollte ebenfalls funktionieren und stellt das Garbage-Collection-System so ein, dass das Heap-Wachstum so weit wie möglich vermieden wird, was jedoch die Garbage-Collection geringfügig verlangsamt.
* Es gibt ein Standard-Timeout von maximal 60 Sekunden für das Herunterfahren. Passe dies bei Bedarf an, falls dies auf deinem Server nicht ausreicht.
* In diesem Beispiel wird kein Screen verwendet, daher ist die OpenSim-Konsole nicht direkt verfügbar.

'''Setup'''
* Erstelle einen Benutzer „opensim“ (achte darauf, die Shell auf /sbin/nologin zu setzen).
* Installiere OpenSim in /opt/opensim.
* Speichere die obige Datei als /etc/systemd/system/opensim.service.

'''Verwendung'''
* systemctl enable opensim
* systemctl disable opensim
* systemctl status opensim
* systemctl start opensim
* systemctl stop opensim
* systemctl restart opensim
* journalctl -u opensim
