# binary logging is required for replication
# log-bin=mysql-bin
# binary logging format - mixed recommended

# vim /etc/my.cnf  //修改expire_logs_days,x是自动删除的天数，一般将x设置为短点，如10
expire_logs_days = x  //二进制日志自动删除的天数。默认值为0,表示“没有自动删除”

> show binary logs;
> show variables like '%log%';
> set global expire_logs_days = 10;
