MySQL (MAriaDB) will not start

Postby MrDog » 02. December 2020 22:44

An intermittent problem with no obvious cause - when it happens I have to re-install XAMPP and then install a database backup!

Control panel shows:
8:34:47 [mysql] Attempting to start MySQL app...
8:34:47 [mysql] Status change detected: running
8:34:49 [mysql] Status change detected: stopped
8:34:49 [mysql] Error: MySQL shutdown unexpectedly.
8:34:49 [mysql] This may be due to a blocked port, missing dependencies,
8:34:49 [mysql] improper privileges, a crash, or a shutdown by another method.
8:34:49 [mysql] Press the Logs button to view error logs and check
8:34:49 [mysql] the Windows Event Viewer for more clues
8:34:49 [mysql] If you need more help, copy and post this
8:34:49 [mysql] entire log window on the forums

The Mysql log shows:

And Windows Event viewer has various entries:

The final one is:

Aborting

And before that :

Failed to initialize multi master structures

and before that

Slave I/O: Fatal error: Invalid (empty) username when attempting to connect to the master server. Connection attempt terminated. Internal MariaDB error code: 1593

I am not running a master/slave setup as far as I know so makes no sense....
