Managing Disk Space by Handling Binlog and Temporary Files in MySQL

Information

To manage binlog files and prevent disk space issues, follow these steps:

1. Verify Recent Backups: Ensure you have recent backups of your database before making any changes.
2. Check Automatic Purging: Run the following command to check if automatic purging is enabled:

   SHOW VARIABLES LIKE 'expire_logs_days';

   If the value is 0, automatic purging is disabled.
3. Enable Automatic Purging: Add the following to your MySQL configuration file to enable automatic purging: 

   [mysqld]
   expire_logs_days = 7  # Adjust this value based on your needs

4. Apply the Setting Immediately: Execute the following command to apply the setting without restarting MySQL: 

   SET GLOBAL expire_logs_days = 7;

5. Manually Purge Old Binlog Files: If necessary, manually purge old binlog files using one of the following commands: 

   -- Remove logs older than 7 days
   PURGE BINARY LOGS BEFORE DATE_SUB(NOW(), INTERVAL 7 DAY);
   -- Or remove specific files (adjust filename as needed)
   PURGE BINARY LOGS TO 'binlog.000154';

Important: Before purging binlog files, ensure you have a recent backup, verify you're not using replication, and confirm you don't need point-in-time recovery for the period covered by these logs.

To remove unnecessary temporary files like keyword1_data.sql, verify that your system is functioning correctly and then delete the file to reclaim disk space.
