数据恢复案例：
1、模拟数据环境
mysql> select * from t1;
+------+-------+
| id | name |
+------+-------+
| 1 | tom |
| 2 | scott |
| 3 | jerry |
| 4 | rose |
| 5 | john |
+------+-------+
5 rows in set (0.00 sec)
删除数据：
mysql> delete from t1;
Query OK, 5 rows affected (0.02 sec)
mysql> commit;
Query OK, 0 rows affected (0.00 sec)
mysql> select * from t1;
Empty set (0.00 sec)
利用日志恢复，将日志生成文本文件进行分析：
[root@mysrv mysql]# mysqlbinlog mysql-bin.000014 >/home/mysql/log14.txt
[root@mysrv mysql]# cat log14.txt

利用二进制日志恢复：
[root@mysrv mysql]# mysqlbinlog mysql-bin.000014 --stop-pos=597 |mysql -u root -p
Enter password:
---在delete操作前停止日志的应用
