MySQL Flashback功能测试

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了MySQL Flashback功能测试相关的知识，希望对你有一定的参考价值。
一、出现问题
经常会遇到操作数据库误删除数据的问题，对于Oracle可以使用flashback的功能来进行恢复，但是在mysql就无能为力了,MySQL没有实现这个功能.但是有一些第三方写出了flashback的功能,今天我就测试了一把，以备不时之需！
二、分析问题
通过百度我找到了几个类似的工具，工具的原理是通过分析binlog日志解析出误操作的语句，然后对其反转，如果是delete语句，则反转为insert语句；insert语句反转为delete语句；update语句反向还是转为update语句，也就是update回去。
下面测试的工具为mysqlbinlog,这个版支持MySQL 5.6, 下载路径及原文链接如下：
http://www.cnblogs.com/youge-OneSQL/p/5249736.html
注意事项
1、在指定--start-position时，需要注意包含table_map_event的位置，否则工具无法找到相关表的元数据信息.
2、要开启binlog.
3、 binlog的格式为row.
4、数据库的版本 MySQL 5.6.29 社区版
5、可恢复:insert, update,delete相关的操作．
三、解决问题
1、 首先当然是要下载好工具
2、 查看一下，要操作的表数据。
mysql> use test Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed #共有六条数据 mysql> select * from t; +----+---------+ | id | name | +----+---------+ | 1 | xm | | 2 | xmj | | 3 | xuwu | | 4 | chuzan | | 5 | chuzan2 | | 6 | chuzan3 | +----+---------+ 6 rows in set (0.00 sec) mysql>
3、测试delete后恢复实验过程
#delete t表的数据，模拟误删除 mysql> delete from t; Query OK, 6 rows affected (0.00 sec) #同时有可能其它用户也在insert数据，我们恢复的时候不能破坏，出现故障后的数据。 mysql> insert into t(name) values(‘王五‘); Query OK, 1 row affected (0.00 sec) mysql> insert into t(name) values(‘赵六‘); Query OK, 1 row affected (0.00 sec) mysql> select * from t; +----+--------+ | id | name | +----+--------+ | 7 | 王五 | | 8 | 赵六 | +----+--------+ 2 rows in set (0.00 sec) #发现误操作最好手工flush logs,生成一个新的binlog日志，恢复的时候不至于太大。 mysql> flush logs;
