== Verify your hard disk space ==

== MYSQL binlogs location ==

== Purge unnecessary binlogs ==

1. Access mysql database
mysql -u user –ppassword
e.g. mysql -u tbdb –ptbdbpw

2. Execute the Purge command:
Examples:
To erase all binlogs before a specific binlog file:
PURGE BINARY LOGS TO 'mysql-bin.010';
To erase all binlogs before a specific Date/Time:
PURGE BINARY LOGS BEFORE '2015-04-02 22:46:26';

== Expire binary log files automatically ==
You can also set the expire_logs_days system variable to expire binary log files automatically after a given number of days.
Simply add this to /etc/my.cnf
[mysqld]
expire-logs-days=60
Note: a 60 days rotation log is enabled by default in more recent TB products.

Restart mysql

Then mysqld will delete them for you automatically
