Troubleshooting MySQL Unexpectedly Crashes in XAMPP: A Step-by-Step Solution

MySQL crashing unexpectedly can be a frustrating issue for developers and users working with XAMPP. However, there is a solution that involves careful manipulation of the MySQL folders and files. Follow these steps to resolve the problem and ensure a stable MySQL environment in your XAMPP installation.

Step 1: Locate XAMPP Installation Directory

Navigate to the root directory where XAMPP is installed, typically found in the C drive or the designated installation drive.

Step 2: Access MySQL Folder

Inside the XAMPP folder, locate the "mysql" folder. This directory contains essential files and folders related to the MySQL database.

Step 3: Create a Backup of the Data Folder

Within the "mysql" folder, identify two key folders: "backup" and "data." Make a duplicate of the "data" folder and name it "data_old." This step ensures you have a backup in case anything goes wrong during the troubleshooting process.

Step 4: Clean Up the Original Data Folder

Navigate to the original "data" folder. Here, selectively delete specific folders and files to resolve potential issues causing MySQL crashes:

Delete the "mysql" folder.
Delete the "performance_schema" folder.
Delete the "phpmyadmin" folder.
Delete the "test" folder.
Delete all other files except the "ibdata1" file.

Ensure you retain the "ibdata1" file and do not delete it. This file is crucial for MySQL functionality.

Step 5: Restore from Backup

Move to the "backup" folder and copy all contents, excluding the "ibdata1" file. Paste these files into the cleaned "data" folder.

Step 6: Start XAMPP

Launch XAMPP and initiate the MySQL service. With the provided solution, MySQL should no longer crash unexpectedly, and your development environment should be stable.
