Recover MySQL Data When Service Won’t Start

If MySQL is unable to start, but the data files still exist, you can try the following methods to recover the data:

1. Check the error log: Start by examining the MySQL error log file, typically located in MySQL’s data directory, to see if there are any specific error messages.
2. Check the MySQL configuration file to make sure that the configuration options are set correctly, especially the path to the data directory.
3. Manually start MySQL: Try manually starting the MySQL service using command line tools or system service management tools (such as systemctl) to see if there are any error messages during the startup process.
4. Repair data files: If MySQL fails to start because of data file corruption, you can try using tools provided by MySQL such as mysqlcheck to repair the data files.
5. Backup and restore: If the above methods do not solve the problem, you can try using MySQL backup and restore tools such as mysqldump or physical backup files to restore data.

Finally, if you are unable to solve the problem, we recommend reaching out to MySQL official support or a professional data recovery service provider for assistance.
