Question 1

Why does MySQL keep shutting down unexpectedly in XAMPP?

Accepted Answer

This usually happens due to port conflicts, corrupted database files, missing permissions, or interference from other software like antivirus programs. The error message and MySQL logs typically provide helpful clues to diagnose the issue.

Question 2

Can changing the MySQL port really fix the issue?

Accepted Answer

Yes, changing the default port (3306) can resolve the problem if another application is using it. Update the port in the my.ini file to an unused one, like 3307, then restart MySQL to see if the issue is resolved.

Question 3

What files should I delete if I suspect MySQL corruption?

Accepted Answer

If you suspect corruption, you can safely delete the ib_logfile0 and ib_logfile1 files in the xampp/mysql/data directory. These log files will be automatically recreated when MySQL starts. Be sure to back up your data folder before making any changes.

Question 4

How do I check if an antivirus is blocking MySQL?

Accepted Answer

Temporarily disable your antivirus software and try starting MySQL. If it starts without errors, it’s likely your antivirus was interfering. Add the XAMPP and MySQL folders to your antivirus exceptions list to prevent future issues.

Question 5

Will I lose my databases if I reinstall MySQL?

Accepted Answer

No, you won’t lose them if you back them up properly. Before reinstalling, copy your databases from xampp/mysql/data (excluding system files). After reinstalling MySQL, you can move your backed-up databases back to the new data folder.
