1、首先我們安裝binlog2sql：
yum -y install epel-release
yum -y install git python-pip
shell> git clonehttps://github.com/danfengcao/binlog2sql.git && cd binlog2sql
shell> pip install -r requirements.txt
--default-timeout=1000
原有數據
mysql> select * from f;
+-----+-----+---------------------+
| uid | did |updateTime |
+-----+-----+---------------------+
| 1 | 18 | 2016-12-06 12:28:18 |
| 2 | 19 | 2016-12-06 12:55:56 |
| 3 | 20 | 2016-12-07 14:00:58 |
| 4 | 21 | 2016-12-07 14:01:00 |
+-----+-----+---------------------+
誤操作mysql> delete from f;
Query OK, 4 rows affected (0.00 sec)
f表被清空
mysql> select * from f;
Empty set(0.00 sec)
2、回滾步驟：
登錄mysql，查看目前的binlog文件
mysql> show master logs;
+------------------+-----------+
| Log_name |File_size |
+------------------+-----------+
| mysql-bin.000001 | 12262268 |
| mysql-bin.000002 | 132776 |
最新的binlog文件是mysql-bin.000002，我們再定位誤操作SQL的binlog位置
$ pythonbinlog2sql/binlog2sql.py -h127.0.0.1 -P3306 -uadmin -p'admin' -dtest -t f--start-file='mysql-bin.000002'
輸出：
DELETE FROM `test`.`f` WHERE `did`=18 AND`updateTime`='2016-12-06 12:28:18' AND `uid`=1 LIMIT 1; #start 4 end 314
DELETE FROM `test`.`f` WHERE `did`=19 AND`updateTime`='2016-12-06 12:55:56' AND `uid`=2 LIMIT 1; #start 4 end 314
DELETE FROM `test`.`f` WHERE `did`=20 AND`updateTime`='2016-12-07 14:00:58' AND `uid`=3 LIMIT 1; #start 4 end 314
DELETE FROM`test`.`f` WHERE `did`=21 AND `updateTime`='2016-12-07 14:01:00' AND `uid`=4LIMIT 1; #start 4 end 314
3、生成回滾sql，並檢查回滾sql是否正確
$ pythonbinlog2sql/binlog2sql.py -h127.0.0.1 -P3306 -uadmin -p'admin' -dtest -t f--start-file='mysql-bin.000002' --start-pos=4 --end-pos=314 -B
輸出：
INSERT INTO `test`.`f`(`did`, `updateTime`,`uid`) VALUES (21, '2016-12-07 14:01:00', 4); #start 4 end 314
INSERT INTO `test`.`f`(`did`, `updateTime`,`uid`) VALUES (20, '2016-12-07 14:00:58', 3); #start 4 end 314
INSERT INTO`test`.`f`(`did`, `updateTime`, `uid`) VALUES (19, '2016-12-06 12:55:56', 2);#start 4 end 314
4、確認回滾sql正確，執行回滾語句。登錄mysql，數據回滾成功。
pythonbinlog2sql/binlog2sql.py -h127.0.0.1 -P3306 -uadmin -p'admin' -dtest -t f--start-file='mysql-bin.000002' --start-pos=4 --end-pos=314 -B | mysql-h127.0.0.1 -P3306 -uadmin -p'admin'
mysql> select * from f;
+-----+-----+---------------------+
| uid | did |updateTime |
+-----+-----+---------------------+
| 1 | 18 | 2016-12-06 12:28:18 |
| 2 | 19 | 2016-12-06 12:55:56 |
| 3 | 20 | 2016-12-07 14:00:58 |
| 4 | 21 | 2016-12-07 14:01:00 |
5、至此，回滾成功！
