Generally, it is not recommended to manually delete MySQL binary log files.mysql-bin.000001As well as other corresponding binary log files. Since the binary log is a binary file used by the MySQL database to record all modification operations, manually deleting these files could lead to the following consequences:
Log backup: If you need to perform data recovery on MySQL, you may need to use these binary log files; however, if the log files have been deleted, data recovery will be impossible.
Master-Slave Replication: If your MySQL instance is configured with "master-slave replication" – meaning that operations performed on the master database are synchronized to the slave database – manually deleting certain binary log files may prevent the slave database from "catching up" with the operation records on the master database.
Database performance: Binary logging is crucial; MySQL requires binary logging to be enabled whenever it performs modification operations. Therefore, insufficient binary logging files can consume more memory and disk I/O, adversely affecting database performance.
If it is indeed necessary to delete these files, you should use backup or other appropriate measures to ensure the integrity of the MySQL data. Additionally, when deleting binary log files, it is generally recommended to use MySQL's built-in tools. PURGE BINARY LOGS Use a command to clear the binary log instead of deleting the file directly.
