MySQL startet auf einmal nicht

[Earth]

Hallo, ich lerne gerade frisch PHP, MySQL und MariaDB (ohne sonstige Programmierkenntnisse) und habe mich eben hier registriert, weil ich seit neuestem das MySQL-Modul nicht öffnen kann.

Hier die Fehlermeldungen, was muss ich tun?

Deine mysql Datenbank muss repariert werden

Dazu öffne bitte nochmal eine neue XAMPP Shell und führe folgendes Command aus:

Code: Select all

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

Lasse dieses Shellfenster bitte offen und öffne eine zweite Shell, in welcher du folgendes Command absetzt:

Code: Select all

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

Nun kannst du beide Shell Fenster wieder schließen und versuchen MariaDB normal über das control Panel zu starten
