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);
