Answers for "cause mysql shutdown unexpectedly"

error: mysql shutdown unexpectedly.

Stop there! Please do not delete anything!

Some of the answers in Stackoverflow or in other platform could leave completely unusable your database!, 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:

Step 1. Rename the folder c:xamppmysqldata to c:xamppmysqldata_old (you can use any name).

Step 2. Create a new folder c:xamppmysql/data.

Step 3. Copy the content that resides in mysqlbackup to the new mysqldata folder.

Step 4. Copy all your database folders that are in mysqldata_old to mysqldata (skipping the mysql, performance_schema, and phpmyadmin folders from data_old).

Step 5. Finally copy the ibdata1 file from mysqldata_old and replace it inside mysqldata folder.

Step 6. Start MySQL from XAMPP control panel.

And, Its DONE . 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.
