[Gelöst] Failed to start Grafana instance.

rehmosch

@thomas-braun Tolle Anleitung die ich mal schnell überflogen habe.

Habe ich es so richtig verstanden:

Node 12, npm 6 und nodeJS sauber installieren! Also vorher deinstallieren?!?

which nodejs node npm && nodejs -v && node -v && npm -v && apt policy nodejs
/usr/bin/nodejs
/usr/local/bin/node
/usr/local/bin/npm

Dann werde ich jetzt gleich mal nach dem Abendessen (Rehbraten mit Rahmschwammerl und SemmelKnödel) deine Anleitung abarbeiten. Danke für deine Mühe ;)

Muss ich was noch beachten?

Danke an alle!

Thomas Braun

@rehmosch Ja, den krummen Quark mit nodejs@16 musst du sauber aus dem System kratzen. Das hast du da schon falsch reingeprügelt.

Und dann sauber node12 installieren.

Hallo Thomas, habe ich alles richtig gemacht? Die letzte Zeile finde ich komisch:

Danke und schönen Sonntag

Werde jetzt mal versuchen Grafana zu starten. Soll ich den Thread dann als gelöst markieren?

Thomas Braun

@rehmosch
Ja, jetzt ist es offenbar senkrecht.

Hab mich an diese Anweisung gehalten:
https://rodnic.de/hausautomation/4-iobroker-influxdb-grafana/

Und so deinstalliert:



sudo apt-get remove grafana



sudo apt-get remove --auto-remove grafana

bin langsam echt am verzweifeln ...

Habe irgendwo im Internet gesehen, das falsche Paket-Adressen im Umlauf sind. Suche gerade den Link ...

Danke Thomas

@rehmosch Das sollte passen. In der verlinkten Anleitung steht aber für ein Debian Buster das falsche Repo für influxdb drin. Das zieht die Version für Stretch rein. Das möchte man glaube ich nicht.

rehmosch

@thomas-braun

Also Influxdb deinstallieren und neuinstallieren?!?

Bin ich hier richtig, der Anleitung zu folgen?

Description: add and remove users and groups
 This package includes the 'adduser' and 'deluser' commands for creating
 and removing users.
 .
  - 'adduser' creates new users and groups and adds existing users to
    existing groups;
  - 'deluser' removes users and groups and removes users from a given
    group.
 .
 Adding users with 'adduser' is much easier than adding them manually.
 Adduser will choose appropriate UID and GID values, create a home
 directory, copy skeletal user configuration, and automate setting
 initial values for the user's password, real name and so on.
 .
 Deluser can back up and remove users' home directories
 and mail spool or all the files they own on the system.
 .
 A custom script can be executed after each of the commands.

Muss ich Grafana wieder reinstallieren und zuvor löschen?

Ich weiß gar nicht wie ich dir danken kann ;)

apt policy influxdb

Von der Homepage:

To run InfluxDB on Raspberry Pi, you will need:
a Raspberry Pi 4+ or 400
a 64-bit operating system.

Von influxdb hab ich selber aber keine Ahnung. Offenbar bauen die das aber nur für 64bit-Systeme.

Auf der anderen Seite auf meinem System:

@thomas-braun

hab den Fehler gefunden und hoffe das ich es so stehen lassen kann.

https://community.grafana.com/t/failed-to-start-grafana-instance/51262/7

hey guys thank you.

the problem was an old grafana installation and under /etc/grafana/ a lot of files was NOT deleted like grafana.ini … after deinstallation.

sudo apt-get --purge remove grafana
sudo apt-get remove --auto-remove grafana

so the old ini files was there but not the new .ini after installation.

thank you guys so much

@rehmosch sagte in Failed to start Grafana instance.:

sudo apt-get --purge remove grafana

das ist bekannt,
ohne den purge Befehl, bleibt die Config erhalten, bedeutet auch, man beginnt bei 0, keine Daten, keine Config mehr

rehmosch

@crunchip aber ich musste es von "Hand" mit rm löschen und der purge Befehl brachte mir leider gar nichts ;( Habe es gut ein Dutzend Mal vergeblich versucht. Hätte es besser beschreiben müssen.

Fazit: sudo rm /etc/grafana/grafana.ini ==== war die Lösung!

Für alle anderen die bei diesem Problem aus dem Log-File von Grafana:
failed to parse "/etc/grafana/grafana.ini"

LG
Liebe Grüße & Danke für Eure Hilfe

das lag dann wohl an deiner "vermurksten" installation

Einfach deinstallieren, nur grafana
sudo apt-get remove grafana

Deinstallieren, grafana und seine Abhängigkeiten
sudo apt-get remove --auto-remove grafana

Bereinige auch deine Konfiguration/Daten
sudo apt-get purge grafana

rehmosch

@crunchip jep, wahrscheinlich ;(
