What Is the “MySQL Shutdown Unexpectedly” Error? Possible Causes

When trying to start the MySQL server through the XAMPP web server control panel, some users have received the error message "Error: MySQL shutdown unexpectedly." The problem may emerge after users reinstall XAMPP on their machine in some situations.

This occurs when MySQL files are corrupted or damaged, in which case you must use the backup folder in the MySQL directory. We will walk you through the process of resolving this error message in this article, so you won't have to worry about anything.

Some possible causes for this error include:

Another program is using the MySQL port: If another program is already using the port that MySQL is configured to use, you will see this error. To fix this, you'll need to change the MySQL port to something else.
The MySQL configuration is corrupt: This can happen if the MySQL configuration file (my.cnf) is corrupt or has been modified incorrectly. If this is the case, you'll need to restore the file from a backup or reset it to the default values.
The MySQL service is not running: In some cases, the MySQL service may not be running at all. This can be due to a number of reasons, but most often it's because of a problem with the MySQL service account or permissions.

Fortunately, there are a few things you can do to try and fix this problem. First, try restarting the MySQL service. If that doesn't work, then you can try changing the MySQL configuration to use a different port. Finally, if all else fails, you can uninstall and then reinstall MySQL.

Let's go through each of these steps in more detail.

How to Fix “Error: MySQL Shutdown Unexpectedly”

Here are a few things you can do to try and fix the "MySQL shutdown unexpectedly" error:

Method 1. Run XAMPP As Administrator

If you are using XAMPP to run MySQL, you will need to run it as an administrator before you can start the MySQL service. To do this, find the XAMPP Control Panel shortcut on your desktop and right-click on it. Then, select "Run as Administrator" from the menu.

Method 2. Restore Your MySQL Backup Folder

If you have a backup of your MySQL folder, you can restore it to fix the "MySQL shutdown unexpectedly" error. By doing so, you will replace the damaged or corrupt files with backups.

To restore your MySQL backup folder, follow these steps:

Close the XAMPP web server completely. Navigate to the location where XAMPP is installed after you've closed the web server. XAMPP is located by default at "C:\xampp."
Open the “mysql” folder. Locate the “data” folder and rename it to “data_old” to store the old files in a safe way. This step is crucial to make sure you have a backup.
After that, right-click anywhere in the directory and select New > Folder from the context menu to create a new folder. Give the newly created folder the name “data”.
After you've created the new data folder, open the “backup” folder. Copy the backup folder's contents and paste them into the newly created “data” folder.
Now that you've completed all of this, run XAMPP as an administrator. Try running the MySQL server once the XAMPP Control Panel is open to see whether the problem persists.

Method 3. Repair the MySQL Database With Shell Commands

If you can't start MySQL, you can try repairing it using shell commands.

To begin, go to the XAMPP Control Panel. By clicking the Shell button in the XAMPP Control Panel, you can launch a shell.
To start MySQL, open a shell and type the following command: mysqld --console --skip-grant-tables --skip-external-locking
After that, use the Control Panel to open another shell window. To repair the database, copy and paste the following command into the new shell window: mysqlcheck -r --databases mysql --use-frm
Stop MySQL from the first shell window, and then close both shell windows after that's done. After that, restart MySQL to see if the problem is still present.

Method 4. Stop the MySQL Service

If all else fails, you can try stopping the MySQL service and manually starting your MySQL service from the XAMPP Control Panel. To do this, follow these steps:

On your keyboard, press the Windows + R keys. This will launch the Run application.
Without the quotation marks, type "services.msc" and hit the Enter key on your keyboard. The Services application will be launched as a result of this.
Scroll down until you see the MySQL service in the alphabetical list. Right-click on it, and then choose Stop from the context menu.
Wait for the service to come to a halt. After that, see if the problem persists by manually starting the MySQL server from the XAMPP Control Panel.

Method 5. Change Your Client and Server Ports

If you are still having problems, you can try changing the default MySQL ports. To do this, you'll need to edit the configuration file for MySQL.

To begin, open Windows Explorer and go to the installation location for xampp.
Navigate to mysql > bin within the xampp folder.
Open the my.ini file with the Notepad application. To do so, right-click the file and select Open with > Notepad from the context menu.
After you've opened the my.ini file, modify the client and server ports as indicated in the image below:
Save the file and restart XAMPP after that. Finally, start the MySQL server to verify if the problem persists.

By following these steps, you should be able to fix the "MySQL shutdown unexpectedly" error. If you are still having trouble or have any questions, please feel free to leave a message below!

The "MySQL shutdown unexpectedly" error is most often caused by a conflict with another program or a problem with the MySQL configuration.
