How to Fix MySQL Shutdown Unexpectedly in XAMPP Without Losing Your Data

• Tutorials

If you’ve encountered the dreaded “MySQL shutdown unexpectedly” error in XAMPP, don’t panic. This error can be alarming, especially if you’re in the middle of a project, but there’s a safe way to resolve it without risking your databases. Before trying any drastic measures like deleting files or changing port settings, follow these steps to restore MySQL safely.

Step-by-Step Guide:

Step 1: Rename the data Folder

• Navigate to your XAMPP installation directory, typically C:\xampp\mysql.
• Rename the data folder to data_old. You can choose any name, but keeping it simple is best for easy identification later.

Step 2: Create a New data Folder

• Inside the same mysql directory, create a new folder and name it data.

Step 3: Copy Backup Files to the New data Folder

• Go to the mysql\backup folder.
• Copy all the contents of this backup folder and paste them into the new data folder you just created.

Step 4: Restore Your Databases

• Now, go to the data_old folder (the one you renamed in Step 1).
• Copy all your database folders from data_old to the new data folder.
  • Important: Do not copy the mysql, performance_schema, and phpmyadmin folders from data_old.

Step 5: Replace the ibdata1 File

• Still in the data_old folder, find the ibdata1 file.
• Copy this file and replace the existing ibdata1 file in the new data folder.

Step 6: Start MySQL

• Open the XAMPP Control Panel and click the Start button next to MySQL.
• If everything was done correctly, MySQL should start without any issues.

Conclusion

And there you have it! No databases were lost, no port changes were needed, no running as administrator, no forced recovery, and no more errors. This method keeps your data intact and gets your MySQL server up and running again with minimal hassle.
