Icinga2 incl. Icingaweb2 und Icinga Director Klonen

Nachfolgender Befehl stoppt den Icinga-Dienst/Daemon:

 # systemctl stop icinga2.service

Anschließend sollen nachfolgende Verzeichisse mit nachfolgenden Befehlen geleert werden:

 # rm /var/lib/icinga2/* -f
 # rm /var/lib/icinga2/api/zones/* -rf
 # rm /var/lib/icinga2/api/repository/* -f
 # rm /var/lib/icinga2/api/packages/* -rf
 # rm /var/lib/icinga2/api/log/* -f
 # rm /var/lib/icinga2/repository/* -f
 # rm /var/lib/icinga2/ca/* -f

und

# rm /var/cache/icinga2/* -f

und entfernen die bereits erzeugten Zertifikate:

# rm /etc/icinga2/pki/* -f

Mit nachfolgenden Befehl kann die bisher durchgeführte Konfiguration gesichert werden:

# tar czfv icinga2-config-backup.tar.gz /etc/icinga2 -C /root
...
