- Emergency handling of insufficient disk space causing MySQL crash
- The solution to the crash caused by insufficient MySQL disk space is: 1. Confirm the problem: Check the error information in the system log; 2. Make room: delete unnecessary files (operate with caution, backup first), clean the MySQL log (clear ib_logfile or slow_query.log after backup, or use mysqlbinlog to clean the binary log and set the log rotation policy); 3. Expand the disk space: Contact the server provider or administrator. Preventive measures include regularly monitoring disk space, setting up alarm mechanisms, rational database design, regular cleaning of useless data, optimizing database performance, and formulating complete backup and recovery strategies to avoid data loss.
