Change the maximum allowed binary log file size in MySQL
By default, the MySQL's maximum binary log file is 1073741824 bytes (1GB).
If you want to change it, edit the MySQL configurations, e.g. /etc/my.cnf
[mysqld] ... ... max_binlog_size 4294967296
Restart MySQL to take effect.
# /sbin/service mysqld restart
Now the new maximum binary log file is set to 4GB.
