本实验模拟把生产库当做测试库，对某张表做了大量DML操作，然后进行闪回的过程。
脚本文件：mysqlbinlog_flashback
此脚本为阿里DBA在mysqlbinlog基础上进行改进来的，网上可以下载到。
一、DML操作
模拟生产库的错误DML操作
mysql> show tables; +----------------+ | Tables_in_test | +----------------+ | kk | | t1 | | t2 | | t3 | | t4 | | t5 | | t6 | | t7 | | t8 | +----------------+ 9 rows in set (0.00 sec) mysql> select * from t8; +------+------+ | id | name | +------+------+ | 1 | jack | | 2 | jack | | 3 | jack | | 4 | jack | +------+------+ 4 rows in set (0.00 sec) mysql> insert into t8 values(5,'steven'); Query OK, 1 row affected (0.04 sec) mysql> insert into t8 values(6,'steven'); Query OK, 1 row affected (0.04 sec) mysql> insert into t8 values(7,'steven'); Query OK, 1 row affected (0.04 sec) mysql> insert into t8 values(8,'steven'); Query OK, 1 row affected (0.03 sec) mysql> update t8 set name='devid' where name='steven'; Query OK, 4 rows affected (0.33 sec) Rows matched: 4 Changed: 4 Warnings: 0 mysql> delete from t8 where name='jack'; Query OK, 4 rows affected (0.04 sec)
对生产库t8做了大量的DML之后，发现操作错误
二、查看binlog events
查看当前binlog和pos
mysql> show master status; +------------------+----------+--------------+------------------+-------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set | +------------------+----------+--------------+------------------+-------------------+ | mysql-bin.000005 | 2195 | | | | +------------------+----------+--------------+------------------+-------------------+ 1 row in set (0.00 sec)
查看binlog events
mysql> show binlog events in 'mysql-bin.000005'; +------------------+------+----------------+-----------+-------------+--------------------------------------------------+ | Log_name | Pos | Event_type | Server_id | End_log_pos | Info | +------------------+------+----------------+-----------+-------------+--------------------------------------------------+ | mysql-bin.000005 | 4 | Format_desc | 330631 | 123 | Server ver: 5.7.23-log, Binlog ver: 4 | | mysql-bin.000005 | 123 | Previous_gtids | 330631 | 154 | | | mysql-bin.000005 | 154 | Anonymous_Gtid | 330631 | 219 | SET @@SESSION.GTID_NEXT= 'ANONYMOUS' | | mysql-bin.000005 | 219 | Query | 330631 | 291 | BEGIN | | mysql-bin.000005 | 291 | Rows_query | 330631 | 348 | # insert into t8 values(5,'steven') | | mysql-bin.000005 | 348 | Table_map | 330631 | 396 | table_id: 116 (test.t8) | | mysql-bin.000005 | 396 | Write_rows | 330631 | 443 | table_id: 116 flags: STMT_END_F | | mysql-bin.000005 | 443 | Xid | 330631 | 474 | COMMIT /* xid=29 */ | | mysql-bin.000005 | 474 | Anonymous_Gtid | 330631 | 539 | SET @@SESSION.GTID_NEXT= 'ANONYMOUS' | | mysql-bin.000005 | 539 | Query | 330631 | 611 | BEGIN | | mysql-bin.000005 | 611 | Rows_query | 330631 | 668 | # insert into t8 values(6,'steven') | | mysql-bin.000005 | 668 | Table_map | 330631 | 716 | table_id: 116 (test.t8) | | mysql-bin.000005 | 716 | Write_rows | 330631 | 763 | table_id: 116 flags: STMT_END_F | | mysql-bin.000005 | 763 | Xid | 330631 | 794 | COMMIT /* xid=30 */ | | mysql-bin.000005 | 794 | Anonymous_Gtid | 330631 | 859 | SET @@SESSION.GTID_NEXT= 'ANONYMOUS' | | mysql-bin.000005 | 859 | Query | 330631 | 931 | BEGIN | | mysql-bin.000005 | 931 | Rows_query | 330631 | 988 | # insert into t8 values(7,'steven') | | mysql-bin.000005 | 988 | Table_map | 330631 | 1036 | table_id: 116 (test.t8) | | mysql-bin.000005 | 1036 | Write_rows | 330631 | 1083 | table_id: 116 flags: STMT_END_F | | mysql-bin.000005 | 1083 | Xid | 330631 | 1114 | COMMIT /* xid=31 */ | | mysql-bin.000005 | 1114 | Anonymous_Gtid | 330631 | 1179 | SET @@SESSION.GTID_NEXT= 'ANONYMOUS' | | mysql-bin.000005 | 1179 | Query | 330631 | 1251 | BEGIN | | mysql-bin.000005 | 1251 | Rows_query | 330631 | 1308 | # insert into t8 values(8,'steven') | | mysql-bin.000005 | 1308 | Table_map | 330631 | 1356 | table_id: 116 (test.t8) | | mysql-bin.000005 | 1356 | Write_rows | 330631 | 1403 | table_id: 116 flags: STMT_END_F | | mysql-bin.000005 | 1403 | Xid | 330631 | 1434 | COMMIT /* xid=32 */ | | mysql-bin.000005 | 1434 | Anonymous_Gtid | 330631 | 1499 | SET @@SESSION.GTID_NEXT= 'ANONYMOUS' | | mysql-bin.000005 | 1499 | Query | 330631 | 1571 | BEGIN | | mysql-bin.000005 | 1571 | Rows_query | 330631 | 1641 | # update t8 set name='devid' where name='steven' | | mysql-bin.000005 | 1641 | Table_map | 330631 | 1689 | table_id: 116 (test.t8) | | mysql-bin.000005 | 1689 | Update_rows | 330631 | 1817 | table_id: 116 flags: STMT_END_F | | mysql-bin.000005 | 1817 | Xid | 330631 | 1848 | COMMIT /* xid=33 */ | | mysql-bin.000005 | 1848 | Anonymous_Gtid | 330631 | 1913 | SET @@SESSION.GTID_NEXT= 'ANONYMOUS' | | mysql-bin.000005 | 1913 | Query | 330631 | 1985 | BEGIN | | mysql-bin.000005 | 1985 | Rows_query | 330631 | 2041 | # delete from t8 where name='jack' | | mysql-bin.000005 | 2041 | Table_map | 330631 | 2089 | table_id: 116 (test.t8) | | mysql-bin.000005 | 2089 | Delete_rows | 330631 | 2164 | table_id: 116 flags: STMT_END_F | | mysql-bin.000005 | 2164 | Xid | 330631 | 2195 | COMMIT /* xid=34 */ | +------------------+------+----------------+-----------+-------------+--------------------------------------------------+
可以看到，所做的操作为291-2195之间的SQL，binlog文件为mysql-bin.000005
三、查看并反向解析binlog

四、数据恢复
将反向解析出来的binlog添加到文本文件
mysqlbinlog_flashback --no-defaults --base64-output=decode-rows -B -v -v --start-position=291 --stop-position=2195 mysql-bin.000005 > flash_back_t8.sql
修改flash_back_t8.sql，将最后的ROLLBACK改为COMMIT。
五、恢复数据
mysql -uroot -p test < flash_back_t8.sql
