Unten finden Sie zwei Beispiele für verschiedene Init-Systeme unter Linux. Passen Sie ggf. die Einstellungen für ihr System an.

Beispielskript für Upstart

theme	Emacs
language	bash

$ nano /etc/init/mmsd.conf
$ service mmsd start

PIDFILE="/var/run/mmsd.pid"


exec start-stop-daemon --start --make-pidfile --pidfile $PIDFILE --chdir $APPPATH --exec $NODEBIN $NODEAPP

end script

Beispielscript für SystemD (hier: CentOS 7):

Erstellen einer Servicedatei für die Applikation in /etc/systemd/system/mms.service
Pfade sowie Benutzer und Gruppen anpassen

Codeblock

language	bash
title	/etc/systemd/system/mms.service

[Service]
ExecStart=/path/to/nodejs/binary /path/to/mongo_management_studio/server.js
Restart=always
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=litixsoft-mms
User=[username that runs the service]
Group=[group the user is in]
WorkingDirectory=/path/to/mongo_management_studio/

[Install]
WantedBy=multi-user.target

3. Einrichten des Dienstes über "systemctl enable mms", Starten durch "systemctl start mms", Status überprüfen über "systemctl status mms", Stoppen über "systemctl stop mms".
