#[脚本自动化安装](https://www.cnblogs.com/kcxg/p/10929968.html)
chmod +x auto_install_mysql.sh
./auto_install_mysql.sh
1. 解压备份
unzip gunzip alldb-20190524-010001.sql.gz
2.sql文件还原
/usr/local/mysql/bin/mysql -uusername -pPASSWORD -f < alldb-20190524-010001.sql (-f 参数表示在导出过程中忽略出现的SQL错误)
3.1 mysqlbinlog
1). binlog拷贝到恢复机上
2). 使用mysqlbinlog 生成sql脚本
mysqlbinlog --database=[db_name] --start-datetime=‘2019-05-23 18:19:12‘ --stop-datetime=‘2019-05-25 21:53:56‘ > 1.sql
3).binlog生成的sql脚本导入
mysql -uuser -ppassword < 1.sql
4).验证数据正确性
3.1 binlog2sql(https://www.cnblogs.com/kcxg/p/10644231.html))
#根据备份文件名称确定开始还原时间以及binlog文件,解析得到sql语句。
python binlog2sql/binlog2sql.py -h127.0.0.1 -P3306 -uadmin -p‘admin‘ -dtest -ttbl --start-file=‘mysql-bin.000052‘ --start-datetime=‘2019-05-27 12:34:00‘
1.登录mysql,查看目前的binlog文件
mysql> show master status;
+------------------+-----------+
| Log_name | File_size |
+------------------+-----------+
| mysql-bin.000051 | 967 |
| mysql-bin.000052 | 965 |
+------------------+-----------+
2.最新的binlog文件是mysql-bin.000052,我们再定位误操作SQL的binlog位置。误操作人只能知道大致的误操作时间,我们根据大致时间过滤数据。
shell> python binlog2sql/binlog2sql.py -h127.0.0.1 -P3306 -uadmin -p‘admin‘ -dtest -ttbl --start-file=‘mysql-bin.000052‘ --start-datetime=‘2016-12-13 20:25:00‘ --stop-datetime=‘2016-12-13 20:30:00‘
输出:
INSERT INTO `test`.`tbl`(`addtime`, `id`, `name`) VALUES (‘2016-12-13 20:26:00‘, 4, ‘小李‘); #start 317 end 487 time 2016-12-13 20:26:26
UPDATE `test`.`tbl` SET `addtime`=‘2016-12-12 00:00:00‘, `id`=4, `name`=‘小李‘ WHERE `addtime`=‘2016-12-13 20:26:00‘ AND `id`=4 AND `name`=‘小李‘ LIMIT 1; #start 514 end 701 time 2016-12-13 20:27:07
DELETE FROM `test`.`tbl` WHERE `addtime`=‘2016-12-10 00:04:33‘ AND `id`=1 AND `name`=‘小赵‘ LIMIT 1; #start 728 end 938 time 2016-12-13 20:28:05
DELETE FROM `test`.`tbl` WHERE `addtime`=‘2016-12-10 00:04:48‘ AND `id`=2 AND `name`=‘小钱‘ LIMIT 1; #start 728 end 938 time 2016-12-13 20:28:05
DELETE FROM `test`.`tbl` WHERE `addtime`=‘2016-12-13 20:25:00‘ AND `id`=3 AND `name`=‘小孙‘ LIMIT 1; #start 728 end 938 time 2016-12-13 20:28:05
DELETE FROM `test`.`tbl` WHERE `addtime`=‘2016-12-12 00:00:00‘ AND `id`=4 AND `name`=‘小李‘ LIMIT 1; #start 728 end 938 time 2016-12-13 20:28:05
3.我们得到了误操作sql的准确位置在728-938之间,再根据位置进一步过滤,使用flashback模式生成回滚sql,检查回滚sql是否正确(注:真实环境下,此步经常会进一步筛选出需要的sql。结合grep、编辑器等)
shell> python binlog2sql/binlog2sql.py -h127.0.0.1 -P3306 -uadmin -p‘admin‘ -dtest -ttbl --start-file=‘mysql-bin.000052‘ --start-position=3346 --stop-position=3556 -B > rollback.sql | cat
输出:
INSERT INTO `test`.`tbl`(`addtime`, `id`, `name`) VALUES (‘2016-12-12 00:00:00‘, 4, ‘小李‘); #start 728 end 938 time 2016-12-13 20:28:05
INSERT INTO `test`.`tbl`(`addtime`, `id`, `name`) VALUES (‘2016-12-13 20:25:00‘, 3, ‘小孙‘); #start 728 end 938 time 2016-12-13 20:28:05
INSERT INTO `test`.`tbl`(`addtime`, `id`, `name`) VALUES (‘2016-12-10 00:04:48‘, 2, ‘小钱‘); #start 728 end 938 time 2016-12-13 20:28:05
INSERT INTO `test`.`tbl`(`addtime`, `id`, `name`) VALUES (‘2016-12-10 00:04:33‘, 1, ‘小赵‘); #start 728 end 938 time 2016-12-13 20:28:05
4.确认回滚sql正确,执行回滚语句。登录mysql确认,数据回滚成功。
shell> mysql -h127.0.0.1 -P3306 -uadmin -p‘admin‘ < rollback.sql
mysql> select * from tbl;
+----+--------+---------------------+
| id | name | addtime |
+----+--------+---------------------+
| 1 | 小赵 | 2016-12-10 00:04:33 |
| 2 | 小钱 | 2016-12-10 00:04:48 |
| 3 | 小孙 | 2016-12-13 20:25:00 |
| 4 | 小李 | 2016-12-12 00:00:00 |
+----+--------+---------------------+
