Purge Master Logs in MySQL

If the files '/var/log/mysql/server.bin.xxx' are large, you can manage them:

log into mysql as root. this is not the systems' root user, this is a different root user that is local to mysql.

# mysql -u root -p

mysql> purge master logs before 'xxxx-mm-dd 00:00:00';

To get today's date: `date +"%Y%m%d %H:%M:%S"`
