XAMPP MySQL service crash after reboot

Question

I just install a XAMPP 7.3.6-2-VC15 for Win64, and when i install it, it's fine, MySQL start from control panel without error, et all is ok.

After rebooting my PC, Apache is still working, but MySQL refuse to start ! I try to reinstall XAMPP, but it's exactly the same. MySQL Work fine, and stop working after reboot.

Here is THe few log i have...

In the control panel :

09:48:10  [mysql]   Attempting to start MySQL app...
09:48:10  [mysql]   Status change detected: running
09:48:11  [mysql]   Status change detected: stopped

09:48:11  [mysql]   This may be due to a blocked port, missing dependencies,

I try the following :

• Change port for other than 3306 => no success
• Run xamp control panel as admin => no success
• remove temporary table ibdata1 and ibtmp1 => no success

If someone have an idea...

EDIT : I try to install as a windows service via admin panel as administrator. And so, i have some new lines in log. Seems user table is corrupted... how can i repair ?

Answer 1

This one helped for me:

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.
