方法一、利用最近的全量备份+增量binlog备份，恢复到误操作之前的状态，但是随着数据量的增大，binlog的增多，恢复起来很费时。
方法二、如果binlog的格式为row，那么就可以将binlog解析出来生成反向的原始SQL

以下是利用方法二写的一个python脚本binlog_rollback.py，可利用此脚本生成反向的原始SQL。

说明：

0、前提是binlog的格式为row
1、要恢复的表操作前后表结构没有发生变更，否则脚本无法解析
2、只生成DML(insert/update/delete)的rollback语句
3、最终生成的SQL是逆序的，所以最新的DML会生成在输入文件的最前面，并且带上了时间戳和偏移点，方便查找目标
4、需要提供一个连接MySQL的只读用户，主要是为了获取表结构
5、如果binlog过大，建议带上时间范围，也可以指定只恢复某个库的SQL
6、SQL生成后，请务必在测试环境上测试恢复后再应用到线上

python2安装MySQLdb

pip install  MySQL-python

#注意一定要在环境有安装mysql-devel不然pip安装mysql-python的时候会报错

#linux上面安装

yum install mysql-devel

python3安装MySQLdb(python3是pymysql)

#下载地址

pip3 install PyMySQL

执行安装

下面是使用python2的脚步语法

2. 演示

#首先创建一个只读账号

root:test> grant select on *.* to 'query'@'127.0.0.1' identified by '123456';

Query OK, 0 rows affected, 1 warning (0.01 sec)

#测试表结构如下

root:test> CREATE TABLE `table1` (

    ->   `id` int(11) NOT NULL AUTO_INCREMENT,

    ->   `c1` int(11) DEFAULT NULL,

    ->   `c2` varchar(20) DEFAULT NULL,

    ->   `c3` int(11) DEFAULT NULL,

    ->   PRIMARY KEY (`id`)

    -> );

Query OK, 0 rows affected (0.09 sec)

#插入三条数据

root:test> insert into table1(c1,c2,c3) values (1,'a',1),(2,'b',2),(3,'c',3);

Query OK, 3 rows affected (0.01 sec)

Records: 3  Duplicates: 0  Warnings: 0

root:test> select * from table1;

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

3.利用脚本生成sql

[root@diandi ~]# python binlog_rollback.py -f /log/mysql/bin/mysql-bin.000002  -o rollback.sql -u query -p 123456 --start-datetime='2016-10-28 00:00:00' -d test

正在获取参数.....

正在解析binlog.....

正在初始化列名.....

正在开始拼凑sql.....

done!

4.查看反向sql

[root@diandi ~]# cat rollback.sql

## at 155848

##161028 17:07:10 server id 22100  end_log_pos 155898 CRC32 0x5000bca7  Delete_rows: table id 351 flags: STMT_END_F

INSERT INTO `test`.`table1`

SET

  id=1

  ,c1=1

  ,c2='a'

  ,c3=1;

## at 155560

##161028 17:04:56 server id 22100  end_log_pos 155626 CRC32 0x11d91e2d  Update_rows: table id 351 flags: STMT_END_F

UPDATE `test`.`table1`

SET

  id=3

  ,c1=3

  ,c2='c'

  ,c3=3

WHERE

  id=3

  AND c1=3

  AND c2='c'

  AND c3=10;

## at 155258

##161028 16:59:31 server id 22100  end_log_pos 155338 CRC32 0x3978c1c1  Write_rows: table id 351 flags: STMT_END_F

DELETE FROM `test`.`table1`

WHERE

  id=3

  AND c1=3

  AND c2='c'

  AND c3=3;

DELETE FROM `test`.`table1`

WHERE

  id=2

  AND c1=2

  AND c2='b'

  AND c3=2;

DELETE FROM `test`.`table1`

WHERE

  id=1

  AND c1=1

  AND c2='a'

  AND c3=1;

5.执行回滚

#直接source整个文件，table1将恢复到原来的空表状态（实际情况，在测试环境上按需索取，然后再恢复线上）

root:test> source /root/rollback.sql

Query OK, 1 row affected (0.01 sec)

Query OK, 1 row affected (0.01 sec)

Rows matched: 1  Changed: 1  Warnings: 0

Query OK, 1 row affected (0.01 sec)

Query OK, 1 row affected (0.01 sec)

Query OK, 1 row affected (0.01 sec)

root:test> select * from table1;

Empty set (0.00 sec)

6.具体的参数使用方法
