MySQL error log - please help

[ALS57]

MySQL has shut down unexpectedly so I cant get back into my localhost website using XAMPP
Can you please get me back into MySQL or suggest a way of recovering my database?
Many thanks
Al

Re: XAMMP Control Panel Error when trying start MySql servic
Postby dibyajena » 01. May 2020 18:08

Open shell from from control panel and start mysql with this command:

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

Open another shell from control panel and repair database with this command:

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

Stop mysql, close shells and restart mysql normally.
