一、基于binlog位置点的恢复
为了演示，刷新一个新的binlog文件，让它单独记录delete删除语句:
MySQL [zhangyou]> flush logs
Query OK, 0 rows affected (0.09 sec)
MySQL [zhangyou]> show master status\G
*************************** 1. row ***************************
File: mysql-bin.000009
Position: 120
Binlog_Do_DB:
Binlog_Ignore_DB:
Executed_Gtid_Set:
1 row in set (0.00 sec)
MySQL [zhangyou]> select * from dede_scores;
+----+--------+------+----------+-----------+

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

12 rows in set (0.00 sec)到此处基于binlog位置点的恢复成功
