做了多年oracle dba，對oralce的閃回是一往情深.如今搞起了mysql,找了個不錯的閃回工具，分享給大家吧。
1.下載
https://github.com/danfengcao/binlog2sql
Search: python-pip
pip 是一個Python包管理工具，主要是用於安裝 PyPI 上的軟件包。
2. 安裝
# yum install python-setuptools -y # rpm -ivh python-pip-7.1.0-1.el6.noarch.rpm --rpmfind.net 下載上傳安裝 # pip install PyMySQL # pip install -r requirments.txt # pwd /usr/local/binlog2sql-master/binlog2sql-master # less README.md --這個必須要看個十遍，八遍的才行
3. 測試用例
(root@localhost) [kk]> create database roidba; Query OK, 1 row affected (0.00 sec) (root@localhost) [kk]> use roidba Database changed (root@localhost) [roidba]> create table roidba ( id int,name varchar(10)); Query OK, 0 rows affected (0.15 sec) (root@localhost) [roidba]> insert into roidba values(1,'mysql'); Query OK, 1 row affected (0.00 sec) (root@localhost) [roidba]> insert into roidba values(2,'oracle'); Query OK, 1 row affected (0.00 sec) (root@localhost) [roidba]> insert into roidba values(3,'mariadb'); Query OK, 1 row affected (0.00 sec) (root@localhost) [roidba]> delete from roidba; Query OK, 3 rows affected (0.01 sec) (root@localhost) [roidba]> select * from roidba; Empty set (0.00 sec)
4. 創建閃回用戶
(root@localhost) [roidba]> GRANT SELECT,REPLICATION SLAVE,REPLICATION CLIENT ON *.* TO flashback@'%' identified by 'flashback'; Query OK, 0 rows affected (0.04 sec) (root@localhost) [roidba]> flush privileges; Query OK, 0 rows affected (0.05 sec)
5. 閃回的要求
1)知道大概的時間點2017-01-12 18:00 ~ 2017-01-12 18:00 2)知道binlog信息 (root@localhost) [roidba]> show binary logs; +------------------+----------------+ | Log_name | File_size | +------------------+----------------+ | mysql-bin.000001 |3828 | | mysql-bin.000002 | 238 | | mysql-bin.000003 |1231 | +------------------+---------------+
6. 解析
--binlog中解析的sql [root@mysql-121 binlog2sql-master]# python binlog2sql/binlog2sql.py -h192.168.80.132 -P3306 -uflashback -pflashback -droidba -troidba --start-file='mysql-bin.000003' --start-datetime='2017-01-12 18:00:00' --stop-datetime='2017-01-12 18:30:00' INSERT INTO `roidba`.`roidba`(`id`, `name`) VALUES (1, 'mysql'); #start 239 end 413 time 2017-01-12 18:10:54 INSERT INTO `roidba`.`roidba`(`id`, `name`) VALUES (2, 'oracle'); #start 492 end 667 time 2017-01-12 18:11:00 INSERT INTO `roidba`.`roidba`(`id`, `name`) VALUES (3, 'mariadb'); #start 746 end 922 time 2017-01-12 18:11:08 DELETE FROM `roidba`.`roidba` WHERE `id`=1 AND `name`='mysql' LIMIT 1; #start 1001 end 1200 time 2017-01-12 18:11:14 DELETE FROM `roidba`.`roidba` WHERE `id`=2 AND `name`='oracle' LIMIT 1; #start 1001 end 1200 time 2017-01-12 18:11:14 DELETE FROM `roidba`.`roidba` WHERE `id`=3 AND `name`='mariadb' LIMIT 1; #start 1001 end 1200 time 2017-01-12 18:11:14 USE roidba; GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'flashback'@'%' IDENTIFIED BY PASSWORD '*6DE874C277DDA35061BD526FB38B6A3C8B3A9254'; USE roidba; flush privileges;
7. 閃回
--閃回sql # python binlog2sql/binlog2sql.py -h192.168.80.132 -P3306 -uflashback -p'flashback' -droidba -troidba --start-file='mysql-bin.000003' --start-position=1001 --stop-position=1200 -B > rollback.sql [root@mysql-121 binlog2sql-master]# less rollback.sql INSERT INTO `roidba`.`roidba`(`id`, `name`) VALUES (3, 'mariadb'); #start 1001 end 1200 time 2017-01-12 18:11:14 INSERT INTO `roidba`.`roidba`(`id`, `name`) VALUES (2, 'oracle'); #start 1001 end 1200 time 2017-01-12 18:11:14 INSERT INTO `roidba`.`roidba`(`id`, `name`) VALUES (1, 'mysql'); #start 1001 end 1200 time 2017-01-12 18:11:14 --開始回滾 [root@mysql-121 binlog2sql-master]# mysql -ubackup -pbackup -h192.168.80.132 <./rollback.sql --具有插入權限纔可以
8.驗證
自己多測試，多動手，看別人做很簡單，其實真的自己上手就不一定了，少說多做，少扯淡。
