MySQL wurde unerwartet beendet

[MFeldhoff]

Guten Morgen,
und schon wieder... Seitdem ich auf Windows 11 upgedated habe, zum 3.x in einem Monat das Problem, dass ich die DB über XAMPP nicht öffnen kann. Es sind aber leider nicht immer dieselben Fehlermeldungen.

Heute wurde mir im log folgendes angezeigt:

Ich werde gleich noch den Text im Shell hinterher schieben:

Hi,

Versuche mal bitte deine mysql Datenbank zu reparieren.
Dazu öffne bitte eine XAMPP Shell und führe folgendes Command aus:

Code: Select all

mysqld --console --skip-grant-tables --skip-external-locking

Lasse die Shell offen und öffne bitte eine zweite XAMPP Shell und führe dort folgendes Command aus:

Code: Select all

mysqlcheck -r --databases mysql --use-frm

Anschließend kannst du beide Shell Fenster schließen und versuchen die Datenbank auf normalem Wege zu starten

Hat funktioniert. DANKE! Was für eine Erleichterung.
