Wiederherstellung von einer alten Version auf eine neue Version von Discourse fehlgeschlagen

Unterstützung Installation
1

Ich möchte mein Discourse von einer sehr alten Version auf die neueste Version aktualisieren.

Ein Sicherungspaket der ursprünglichen Discourse-Installation enthält eine Datei namens meta.json:

{"source":"discourse","version":20160405172827}

Beim Wiederherstellen des Backups in der neuesten Discourse-Version trat folgende Fehlermeldung auf:

Kann mir jemand helfen? Danke!

Es gibt hier Experten, die sicher bessere Antworten als ich haben werden, aber trotzdem: Vielleicht kannst du versuchen, eine ältere Version von Discourse zu installieren (die der Version deines Backups entspricht), dann dein Backup wiederherzustellen und anschließend Discourse über die Befehlszeile zu aktualisieren.

Herzlichen Glückwunsch! Sie sind die erste Person, von der ich weiß, dass sie diesen Fehler gemeldet hat. :slight_smile:
Ich habe ihn vor zwei Wochen behoben und dachte mir: „Wow, noch hat niemand das gemeldet, obwohl es schon sehr lange kaputt ist.

4

Nur zur Info: Würde mein Vorschlag in diesem Fall funktionieren?

Solange du eine alte Version findest, bei der die Wiederherstellung noch funktioniert, ja. Aber du müsstest vielleicht auch eine Version von discourse_docker finden, die mit einer alten, nicht mehr unterstützten Version von Discourse kompatibel ist. Das macht die Sache etwas komplizierter. :wink:

Vielen Dank für deine Antwort. Dein Vorschlag hat funktioniert. Ich habe dieses Problem umgangen, aber jetzt habe ich ein anderes Problem.
:joy:

Danke für deine Antwort. Auf dem Bus nach Hause habe ich darüber nachgedacht, wo man solch ein altes Bild finden könnte. :rofl: :rofl: :rofl:

8

Ah, ja, ich glaube, es gab noch einen Fehler. Stelle sicher, dass die dump.sql vor dem Hinzufügen zur tar-Datei gzip-komprimiert ist. Das Backup muss eine dump.sql.gz enthalten.

9

In meinem Fall gibt es eine dump.sql, aber keine dump.sql.gz. Ich versuche es erneut.

10

Nachdem ich dump.sql komprimiert und die Sicherungsdatei erneut hochgeladen habe, ist dieser Fehler aufgetreten. Können Sie mir helfen? :smiley:

https://meta.discourse.org/t/restore-failed-at-validating-metadata/31318/2

Ich dachte, ich könnte mein Problem mit diesem Beitrag lösen, aber ich konnte ihn nicht finden oder er war privat, als ich diese Seite besuchte.

12

Hallo, machst du dir immer noch Sorgen wegen dieses Problems? Ich habe bereits alles in meiner Macht Stehende getan, aber mein Problem lässt sich immer noch nicht lösen. Ich bitte um deine Hilfe :sweat_smile:

13

Hast du dieses Mal versucht, ein anderes Backup wiederherzustellen?

Kannst du außerdem einen Blick in die Datei dump.sql werfen? In den ersten paar Zeilen sollte dort etwas wie -- Dumped by pg_dump version 9.5.12 stehen.

14

Ich habe eine Sicherungsdatei mit der Version 20160405172827 erneut exportiert, sie wie bisher verarbeitet und hochgeladen. Nach dem Import habe ich immer noch dieses Problem: undefined method ’ for nil:NilClass`

Hier ist der Inhalt meiner dump.sql-Datei:

--
-- PostgreSQL database dump
--

-- Dumped from database version 9.4.8
-- Dumped by pg_dump version 9.4.9

SET statement_timeout = 0;
SET lock_timeout = 0;
SET client_encoding = 'UTF8';
SET standard_conforming_strings = on;
SET check_function_bodies = false;
SET client_min_messages = warning;

DROP SCHEMA IF EXISTS restore CASCADE; CREATE SCHEMA restore; SET search_path = restore, public, pg_catalog;

SET default_tablespace = '';

SET default_with_oids = false;

-- PostgreSQL database dump complete
--

Exportiert von PostgreSQL v9.4.8, aber ich verwende jetzt v10.11. Wird das der Punkt sein?

PS: Ich habe versucht, dump.sql manuell mit dem Befehl psql -h 127.0.0.1 -U discourse -d discourse < dump.sql zu importieren. Das funktioniert. Aber meine Discourse-Oberfläche hat sich nicht geändert.

15

Der Datei-Header sieht in Ordnung aus. Ich habe gerade eine Wiederherstellung damit getestet, und sie hat funktioniert.

Vielleicht liegt ein Fehler in der von dir erstellten Datei vor. Im Verzeichnis, in dem sich die dump.sql-Datei und der uploads-Ordner befinden, habe ich die folgenden Befehle ausgeführt, um ein neues Archiv zu erstellen:

gzip dump.sql
tar -czvf discourse-2019-12-13-183529-v20160405172827.tar.gz uploads/ dump.sql.gz
16

Hey, vielen Dank für deine Unterstützung in letzter Zeit. Mit Hilfe eines guten Programmierfreundes habe ich einen Teil des Skripts angepasst und schließlich das Backup wiederhergestellt. Falls du wissen möchtest, was wir gemacht haben, hinterlasse mir gerne eine Nachricht.

Allerdings bin ich auf ein weiteres lästiges Problem gestoßen: Mein ursprüngliches Discourse-System nutzte SSO. Nachdem ich das Backup wiederhergestellt habe, möchte ich meinen Benutzernamen und mein Passwort ändern, um mich beim neuen Discourse anzumelden. Das ist jedoch nicht möglich, da ich nicht als Administrator eingeloggt bin und keine Berechtigungen habe, die Anmeldung zu ändern. Was soll ich tun?

17

Dieser Artikel hat mein Problem endlich gelöst. Jetzt nutze ich Discourse mit Freude.
