Redis oder MongoDB?

FrankM last edited by FrankM

Ich hatte mich bei meiner damaligen Installation für Redis entschieden, diese DB hält die Daten im Speicher vor. Sollte das mal in Zukunft ein Problem werden, wenn ich mal 100000 User habe , dann bräuchte man evt. mal ein Tool um die Redis Datenbank in eine MongoDB zu migrieren.

Hier ist so ein Tool https://github.com/BenLubar/nodebb-postgres-converter

Heute mal wieder benutzt, um bei meinem Bruder auf der Kiste nach dem Rechten zu schauen. Absolut genial. Sollte man evt. nicht zu "geheime" Sachen drüber schicken (meine die Leitung), aber für ein wenig Service ist das Tool wirklich super zu gebrauchen.

Nachdem ich den ROCKPro64 jetzt auf den Mainline umgestellt habe, lief meine Testinstallation von Grav nicht mehr.

Bei Serverumzug daran denken, das das Passwort der Redis Datenbank in der Konfig /etc/redis/redis.conf und in der NodeBB Konfig /home/user_nodebb/nodebb/config.json zu ändern ist.
