Tip: Purging Binary Logs in MySQL

Stay out of trouble regarding reaching maximum disk space by purging old logs in MySQL when they are no longer needed.


All data modifications of MySQL are updated onto logs in binary format. At times, if maintenance, such as backup, is not in place, and the data storage reaches the maximum of the disk space, you could run into trouble. MySQL may not be accessible for read/write operations, other applications cannot perform any operations, etc. You need to be the administrator to perform this:

PURGE BINARY LOGS BEFORE '2017-11-24 00:00:01';

This ensure that the binary logs are purged and the space is made available for other applications to use.
