MySQL 5.1.x | InnoDB | Windows
My mysql data directory is starting to fill up with bin logs.
I currently have the following settings configured in my windows mysql server:
[mysqld]
log-bin
server-id=1
binlog-do-db=foodb1
binlog-do-db=foodb2
expire_logs_days=25
I'm planning to change the expire_logs_days setting to expire_logs_days=10
and bounce the mysql service. How soon after making this change can I expect the old bin logs to get clear out.
Is this only done as part of a nightly scheduled task? Or should this be immediate?
Best Answer
It will be handled immediately on mysql startup.
You do not have to wait for a mysql restart.
First, set
expire_logs_days
to be 10 in /etc/my.cnfNext, log in to mysql and run this
Note the query's date and time
Thus, the PURGE BINARY LOGS command will delete all binlogs whose datetime stamp predates
2012-12-11 00:00:00
.Finally, run this command
That's it. No restart needed for installing expire_logs_days.
As for the replication parameters, yes restart is required.
