Fix MySQL Won’t Start After Binlog Deletion

If MySQL cannot start after deleting binlog, it may be due to the necessary binlog files being deleted. Here is a solution:

1. Recover deleted binlog files: Attempt to retrieve or restore the deleted binlog files from a backup. If unable to recover, consider regenerating these binlog files.
2. Specify a new binlog file name: If the deleted binlog file cannot be recovered, you can specify a new binlog file name in the my.cnf configuration file and then restart the MySQL service.
3. Disable the binlog feature: If it is impossible to retrieve or regenerate the binlog files, you can consider disabling the binlog feature in the my.cnf configuration file, and then restart the MySQL service.
4. Rebuild the binlog file: If you cannot recover or regenerate the binlog file, you can consider deleting all data files, and reinitializing the MySQL instance, then start recording the binlog again.

Please make sure to back up the database before performing the above operation, and carefully consider the risk of potential data loss. If you are unsure how to proceed, we recommend seeking help from a professional database administrator or technical support.
