Flush MySQL log-bin data and disable binary log files

If your disk is starting to run out of space due to an excess of mysql-bin.XXXXXXXX files here's what to do to fix that.

vi /etc/my.cnf

under 'log-bin=mysql-bin' (the destination could be different in your my.cnf) put:

expire_logs_days = 10

Change 10 to whatever you're comfortable with.

or you can simply disable the binary log files by uncommenting the line:

# log-bin=mysql-bin

You'll also want to remove all the excessive binary log files like so:

mysql -u root -p -e "PURGE BINARY LOGS BEFORE '2012-02-15 09:00:00';"


In case you can't shutdown mysqld do the following:

pidof mysqld
