When MySQL shuts down unexpectedly, it could be due to various reasons such as incorrect configuration, memory allocation issues, or system errors. Here are a few troubleshooting steps you can try:
1. Check the MySQL error logs:
- The error logs can provide helpful information about the cause of the unexpected shutdown. Look for any error messages or warnings.
2. Verify system resources:
- Check if your system has sufficient memory and disk space. Inadequate resources can lead to unexpected shutdowns.
3. Restart the MySQL service:
- Sometimes, a simple restart of the MySQL service can resolve the issue. Use the appropriate command to restart the service based on your operating system.
4. Test the database integrity:
- Run a database consistency check to ensure the database is in a healthy state. In MySQL, you can use the `mysqlcheck` command.
5. Review configuration settings:
- Verify the MySQL configuration parameters and ensure they are correctly set up. Pay attention to options like `innodb_buffer_pool_size`, `max_connections`, etc.
6. Investigate other system logs:
- Check the system logs for any related errors or warnings, as MySQL shutdowns could be influenced by other components or dependencies.
If the issue persists, you may need to provide more specific details or seek assistance from the MySQL community or support team.

(1) Go to https://github.com/sentgine/PyAutomateHub/blob/main/fix_mysql_error.py.
(2) Download the "fix_mysql_error.py" file.
(3) Run it in the terminal by typing "python fix_mysql_error.py."
This will resolve the issue for you, eliminating the need for manual
intervention from now on.
Note: Ensure that you check the code starting at line 76 to confirm
whether the directory matches your XAMPP folder installation. Look for
the following lines of code below and make changes if necessary. In my case,
my XAMPP installation is located at "C:\xampp."
# Specify the old and new paths
original_folder_path = r'C:\xampp\mysql\data'
new_folder_path = r'C:\xampp\mysql\data_old'
new_subfolder_path = r'C:\xampp\mysql\data'
backup_folder_path = r'C:\xampp\mysql\backup'
ibdata_file_path = r'C:\xampp\mysql\data_old\ibdata1'

So, before deleting files, first try to do what the error message in XAMPP
message panel recommend you to do, using the MySQL backup folder which is
included with XAMPP. So do the next:
Rename the folder mysql/data to mysql/data_old (you can use any name)
Create a new folder mysql/data
Copy the content that resides in mysql/backup to the new mysql/data folder
Copy all your database folders that are in mysql/data_old to mysql/data
(skipping the mysql, performance_schema, and phpmyadmin folders from data_old)
Finally copy the ibdata1 file from mysql/data_old and replace it inside
mysql/data folder
Start MySQL from XAMPP control panel
And, voilà. No databases lost, no ports changed, no run as administrator,
no force recovery, no kill mysqld process, no restoring from previous versions,
no more errors.

Rename folder mysql/data to mysql/data_old
Make a copy of mysql/backup folder and name it as mysql/data
Copy all your database folders from mysql/data_old into mysql/data (except mysql, performance_schema, and phpmyadmin folders)
Copy mysql/data_old/ibdata1 file into mysql/data folder
Start MySQL from XAMPP control panel

1_ Rename the folder mysql/data to mysql/data_old (you can use any name)
2_ Create a new folder mysql/data
3_ Copy the content that resides in mysql/backup to the new mysql/data folder
4_ Copy all your database folders that are in mysql/data_old to mysql/data (skipping the mysql, performance_schema, and phpmyadmin folders from data_old)
5_ Finally copy the ibdata1 file from mysql/data_old and replace it inside mysql/data folder
=> Start MySQL from XAMPP control panel
*************************DONT DELETE ibdata1 FILE*************************
xxxxxxxxxx
exit Xampp server
go to your C:\xampp\mysql\data directory
delete the ibdata1 file
restart xampp server
I also had to delete ib_logfile0 and ib_logfile1 to get it to work

Instead, first try using the MySQL backup folder which is included with XAMPP. So do the next:
1.Rename the folder mysql/data to mysql/data_old (you can use any name)
2.Create a new folder mysql/data
3.Copy the content that resides in mysql/backup to the new mysql/data folder
4.Copy all your database folders that are in mysql/data_old to mysql/data (skipping the mysql, performance_schema, and phpmyadmin folders from data_old)
5.Finally copy the ibdata1 file from mysql/data_old and replace it inside mysql/data folder
6.Start MySQL from XAMPP control panel
And, voilà!

IMPORTANT: do NOT delete ibdata1 file. You could destroy all your databases.
Instead, first try using the MySQL backup folder which is included with XAMPP.
So do next steps:
Rename folder mysql/data to mysql/data_old
Make a copy of mysql/backup folder and name it as mysql/data
Copy all your database folders from mysql/data_old into mysql/data

Copy mysql/data_old/ibdata1 file into mysql/data folder
Start MySQL from XAMPP control panel

Steps to fix this problem –
1. Stop the XAMPP server, MySQL and Apache
2. Create a backup of the “/xampp/mysql/data” folder using a compression software
3. Rename the “/xampp/mysql/data” folder to “/xampp/mysql/data-old”
4. Create a new folder and name it “/xampp/mysql/data”
5. Copy all folders from the “/xampp/mysql/backup” and paste it to
the “/xampp/mysql/data” folder, which you have just created
6. Copy all the databases from the “/xampp/mysql/data-old” folder
and paste it to the “/xampp/mysql/data” folder
7. Finally copy the “ibdata1” and all of the log files including
“ib_logfile0, ib_logfile1 ” from “/xampp/mysql/data-old”
and paste it to the “/xampp/mysql/data” folder
8. Start MySQL from the XAMPP control panel
9. Go to phpMyAdmin to check if all the databases are available and running properly
