[gelöst] Backitup Problem mit Influxdb 1.x

[Thomas Braun]

@darkblu

sudo systemctl disable influxdb.service

nimmt influxdb dann auf dem RPi5 aus dem 'Autostart' raus. Muss ja nicht permanent mitlaufen.

[Marc Berg]

@darkblu sagte in Backitup Problem mit Influxdb 1.x:

muss ich dann noch auf dem Raspi 4 in der influxdb.conf die IP .40:8086 eintragen

Nein. Nur die :8088, wie in der Doku angegeben.

[darkblu]

da bin ich wieder.
Auf dem ioBroker Raspi 5 habe ich nun auch Influxdb installiert, funktioniert leider immer noch nicht.

Wenn ich laut Doku und euch bei dem entfernten Server (IP.39)

bind-address = "<InfluxDB-IP>:8088"

eingebe, (egal ob :8088, oder 0.0.0.0:8088 oder mit IP davor)
bekomme ich direkt diese Fehlermeldung im Log:

Error: connect ECONNREFUSED 192.168.178.39:8086

das hat ja jetzt auch erstmal nix mit Backitup zu tun, das kommt direkt nach Umstellung von 8086 zu 8088.

Falls noch jemand eine Idee hat...

[simatec]

@darkblu Wenn die InfluxDB von einem entfernten Server gesichert werden soll, müssen in der influxdb.conf auf dem entfernten Server die Remote-Rechte für den RPC-Dienst angepasst werden.

bind-address = "0.0.0.0:8088"

Nach dem Änderungen in der Konfiguration muss der InfluxDB-Dienst neugestartet werden.

[darkblu]

@simatec , das habe ich gemacht,
nach dem reboot des entfernten Servers bekomme ich direkt den Fehler vom Influx Adapter auf dem ioBroker Raspi.
Siehe mein Post über deinem.

Kann ich auf dem entfernten Server einfach nochmal Influx installieren ohne das die bestehende Datenbank verloren geht ?
Vielleicht ist da ja etwas „schief“ und würde dann repariert.

Es ist absolut nicht mehr nachvollziehbar, was du wie geändert hast und wie der Stand jetzt ist. Bitte die influxdb.conf auf dem RPi4 zeigen, sowie die Einstellungen des InfluxDB Adapters.

Wo hast du

sudo systemctl disable influxdb.service

ausgeführt?

[darkblu]

@marc-berg , erst mal Danke, dass du dir das angucken willst.

Hier die influxdb.conf vom Raspi 4 (dem entfernten System):

hier die Einstellungen der Influxdb auf dem ioBroker Raspi (5):

sudo systemctl disable influxdb.service

habe ich auf dem ioBroker Raspi 5 ausgeführt.

natürlich steht jetzt in der influxdb.conf:

bind-address = ":8086"

weil, wenn ich dort ":8088" eintrage, bekomme ich auf dem ioBroker Raspi 5 von dem Influxdb Adapter sofort diesen Fehler:

Error: connect ECONNREFUSED 192.168.178.39:8086

Vielleicht noch wichtig zu wissen, auf dem Raspi 4 ist auch noch ioBroker drauf, der mittels

systemctl mask iobroker.service

aus dem Autostart genommen wurde.

Wahrscheinlich ist es am besten, wenn ich am WE die SSD vom Raspi 4 platt mache und RaspiOS, Influx und Grafana noch mal ganz neu installiere.

Oder Du korrigiert einfach die Fehler:

bind-address = ":8086"

Das ist falsch! Hier muss die 8088 rein. Hatte ich oben geschrieben. Wenn dann noch Fehler kommen, ist noch was anderes faul.

EDIT: das muss natürlich ganz oben rein, hier:

# Bind address to use for the RPC service for backup and restore.
bind-address = ":8088"

Und die Zeile unten mit # auskommentieren.

[Marc Berg]

@darkblu

Noch zur Erklärung, diese Stelle hier ist da, um das Backup/Restore via Port 8088 von einem entfernten System zu aktivieren:

# Bind address to use for the RPC service for backup and restore.
bind-address = ":8088"

Diese folgende Stelle ist für die "normale" Kommunikation, also auch von InfluxDB Adapter über Port 8086. Das kann alles auskommentiert bleiben, dann greifen die Standard-Einstellungen, die so okay sind.

[http]

  # Determines  whether HTTP endpoint is enabled.
  # enabled = true

  # The bind address used by the HTTP service.
  # bind-address = ":8086"

[darkblu]

@marc-berg , leider nur Teilerfolg.

Ein Backup mit dem Backitup Adapter bringt immer noch diesen Fehler:

influxDB: Error: Command failed: influxd backup -portable -database iobroker-db -host 192.168.178.39:8086 "/opt/iobroker/backups/influxDB_2024_11_05-15_58_05_backupiobroker"
2024/11/05 15:58:05 Invalid metadata blob, ensure the metadata service is running (default port 8088)
backup: invalid metadata received

Dafür ist das hier jetzt weg:

Error: connect ECONNREFUSED 192.168.178.39:8086

Das sind die Einstellungen in Backitup unter Influxdb:

@darkblu sagte in Backitup Problem mit Influxdb 1.x:

Command failed: influxd backup -portable -database iobroker-db -host 192.168.178.39:8086

Für das Backup muss es Port 8088 sein. Ändere das in der Backitup Config.
