MySQL startet nicht

Postby MarkKnochen » 19. February 2019 09:34


ich versuche ein XAMPP mit PHP 7.3.1 zu starten, der Apache läuft, aber die MySQL Datenbank startet nicht:

von der Konsole über versuche ich es gerade mit

sudo /Applications/XAMPP/xamppfiles/sbin/mysqld

u.a. mit diesen Fehlern.

InnoDB: 3) If the file system or the disk is broken, and you cannot remove
InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf
InnoDB: and force InnoDB to continue crash recovery here.

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see

We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

Server version: 10.1.37-MariaDB
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 153427 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
