利用binlog2sql闪回丢失数据

    today,i'll using the open source tool named "binlog2sql" which is release by danfengchao to do some flashback test.

    here's the github address:https://github.com/danfengcao/binlog2sql

    according to the readme.md doc,using "git" command to download it at the beginning:

 ns-notepc399+jujun@ns-notepc399 MINGW64 /d/vagrant
 $ git clone https://github.com/danfengcao/binlog2sql.git && cd binlog2sql
 Cloning into 'binlog2sql'...

 Resolving deltas: % (/), done.
 ns-notepc399+jujun@ns-notepc399 MINGW64 /d/vagrant/binlog2sql (master)

    secondly,"pip" command need to be installed,which can be downloaded on the official

website:https://pypi.org/project/pip/

    the latest version is 10.0.1 now,i choose the tar package to download.

    then,use the "pip" command to install necessary python package below:

  the binlog2sql tool has been installed,let's begin the test now:

 

 (root@localhost mysql3306.sock)[zlm]::>create table flash_test(
     -> id int unsigned not null auto_increment,
     -> code bigint unsigned not null default '',
     -> primary key(id)
     -> ) engine=innodb charset utf8mb4;
 Query OK,  rows affected (0.02 sec)

 (root@localhost mysql3306.sock)[zlm]::>delimiter $$
 (root@localhost mysql3306.sock)[zlm]::>create procedure pro_insert (count int)
     -> begin
     -> declare i int unsigned default ;
     -> start transaction;
     -> while i < count do
     -> insert into flash_test(code) values(i);
     -> set i=i+;
     -> end while;
     -> commit;
     -> end;
     -> $$
 Query OK,  rows affected (0.00 sec)

 (root@localhost mysql3306.sock)[zlm]::>delimiter ;
 (root@localhost mysql3306.sock)[zlm]::>call pro_insert();
 Query OK,  rows affected (0.33 sec)

 (root@localhost mysql3306.sock)[zlm]::>select count(*) from flash_test;
 +----------+
 | count(*) |
 +----------+
 |     |
 +----------+
  row in set (0.01 sec)

 (root@localhost mysql3306.sock)[zlm]::>select * from flash_test limit ;
 +----+------+
 | id | code |
 +----+------+

 |   |     |
 |   |     |
 +----+------+
  rows in set (0.00 sec)

 (root@localhost mysql3306.sock)[zlm]::>

  then,pretend to delete all the records in the table "flash_table" by accidentally:

 

 (root@localhost mysql3306.sock)[zlm]::>show binary logs;
 +------------------+-----------+
 | Log_name         | File_size |
 +------------------+-----------+
 | mysql-bin. |        |
 | mysql-bin. |        |
 | mysql-bin. |    |
 +------------------+-----------+
  rows in set (0.00 sec)

 (root@localhost mysql3306.sock)[zlm]::>flush logs;
 Query OK,  rows affected (0.02 sec)

 (root@localhost mysql3306.sock)[zlm]::>delete from flash_test;
 Query OK,  rows affected (0.05 sec)

 (root@localhost mysql3306.sock)[zlm]::>select count(*) from flash_test;
 +----------+
 | count(*) |
 +----------+
 |         |
 +----------+
  row in set (0.00 sec)

 (root@localhost mysql3306.sock)[zlm]::>show binary logs;
 +------------------+-----------+
 | Log_name         | File_size |
 +------------------+-----------+
 | mysql-bin. |        |
 | mysql-bin. |        |
 | mysql-bin. |    |
 | mysql-bin. |     |
 +------------------+-----------+
  rows in set (0.00 sec)

 (root@localhost mysql3306.sock)[zlm]::>

   it's the right time using the binlog2sql to flashback the missing data:

    what's amazing is that there're no delete operation found in the existent binlog files at all,how can that happen?let's use the original tool of MySQL itself's to see the details:

    throught the evidence above,i'm afaid the binlog2sql tool didn't recognize the right path of the binlog files and  cast an exception at all.Am i right?

 

 [root@zlm3 :: ~/binlog2sql/binlog2sql]
 #python binlog2sql.py -h192.168.1. -P3306 -uroot -pPassw0rd -dzlm -tflash_table --start-file='/data/mysql/mysql3306/logs/mysql-bin.000004' --only-dml --sql-type delete --stop-never > flashback3.sql

    unfortunately it still doesn't work,i'm confused and have no idea now,maybe i'll test it again text time.Let's see then.

 

Summury:

• binlog2sql is coded by python,in order to use it you need to install python and relevant packages.
  
• some parameter such as "binlog_format=row","binlog_row_image=full" etc. in MySQL Server should be satisfied with.
  
• some privileges such as "super"/"replication client","replication slave" etc. in MySQL Server should be satisfied with too.
  
• it seems more inconvenient rather than the MyFlash tool does.
