清理bin-log日志（mysql-bin日志清理）

清理bin-log日志（mysql-bin日志清理），主从复制中的机器不要使用此方法。

1.查看档案

mysql> show binary logs;

+----------------+-----------+

| Log_name | File_size |

+----------------+-----------+

| ablelee.000001 | 150462942 |

| ablelee.000002 | 125 |

| ablelee.000003 | 106 |

+----------------+-----------+

2.删除bin-log(删除ablelee.000003之前的而没有包含ablelee.000003)

mysql> purge binary logs to 'ablelee.000003';

Query OK, 0 rows affected (0.16 sec)

3. 查询结果(现在只有一条记录了.)

mysql> show binlog events\G

*************************** 1. row ***************************

Log_name: ablelee.000003

Event_type: Format_desc

Server_id: 1

End_log_pos: 106

(ablelee.000001和ablelee.000002已被删除)

mysql> show binary logs;

+----------------+-----------+

| Log_name | File_size |

+----------------+-----------+

| ablelee.000003 | 106 |

+----------------+-----------+

1 row in set (0.00 sec)
