在MySQL中执行以下命令：

复制代码 代码如下:

PURGE {MASTER | BINARY} LOGS TO ‘log_name'

PURGE {MASTER | BINARY} LOGS BEFORE ‘date'

PURGE {MASTER|BINARY} LOGS BEFORE DATE_SUB(NOW(),INTERVAL 7 DAY);

例如：

复制代码 代码如下:

mysql>PURGE MASTER LOGS TO ‘mysql-bin.010′;

mysql>PURGE MASTER LOGS BEFORE ‘2008-06-22 13:00:00′;

mysql>PURGE MASTER LOGS BEFORE DATE_SUB( NOW( ), INTERVAL 7 DAY);
