直接从官网下载软件包，照着github上给的方法，虽然可以安装成功，但是执行如下命了报错，由于此工具源代码是是别人所写，目前暂时没找到是代码的哪个地方导致的语法错误。有知道的网友朋友可以友情提醒下，谢谢。

[root@git-server binlog2sql]# python binlog2sql.py -h227.0.0.1 -P3306 -uadmin -p'admin'  -dzixun3 -tzx_scores --start-file='MySQL-bin.000006' -B  |awk -F '[;]' '{print $1 ";"}'|grep 'INSERT'
  File "binlog2sql.py", line 73
    with temp_open(tmp_file, "w") as f_tmp, self.connection as cursor:
                                          ^
SyntaxError: invalid syntax
[root@git-server binlog2sql]# pwd
/root/binlog2sql
[root@git-server binlog2sql]#

于是采用去年在https://github.com上下载的binlog2sql代码包，安装正常，而且也没有报错。

于是才有下面的测试：
查看当前的记录到日志的binlog文件

MySQL [zixun3]> show master status\G
*************************** 1. row ***************************
             File: mysql-bin.000005
         Position: 686
     Binlog_Do_DB: 
 Binlog_Ignore_DB: 
Executed_Gtid_Set: 
1 row in set (0.00 sec)

为了方便测试，刷新binlog，生成新的binlog日志文件来记录mysql的操作的sql

MySQL [zixun3]> flush logs;
Query OK, 0 rows affected (0.07 sec)

MySQL [zixun3]> show master status\G
*************************** 1. row ***************************
             File: mysql-bin.000006

python binlog2sql.py -h227.0.0.1 -P3306 -uadmin -p'admin'  -dzixun3 -tzx_scores --start-file='mysql-bin.000006'  -B|more

IT 1; #start 4 end 328 time 2018-05-23 14:55:23

-B参数使用是生成回滚的语句

binlog内容格式简单说明如下：

基于位置点的恢复：

BEGIN 和COMMIT之间的才是需要回滚的sql语句。回滚的位置点是：194---328

BEGIN
/*!*/;

直接登陆MySQL执行上面的回滚sql语句就可以了
MySQL [zixun3]> delete from zx_scores;
Query OK, 12 rows affected (0.00 sec)
MySQL [zixun3]> select * from zx_scores;
Empty set (0.00 sec)

此sql格式还不能直接用来恢复到数据库中，需要简单的处理下：

[root@git-server binlog2sql]# python binlog2sql.py -h227.0.0.1 -P3306 -uadmin -p'admin'  -dzixun3 -tzx_scores --start-file='mysql-bin.000006'  --start-position=760 --stop-position=1083  -B|awk -F '[;]' '{print $1 ";"}'
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('大将', 29000, 15, 1, 12);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('上将', 24000, 12, 1, 11);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('中将', 19000, 11, 1, 10);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('少将', 14000, 10, 1, 9);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('上校', 9000, 9, 1, 8);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('中校', 6000, 8, 1, 7);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('少校', 5000, 7, 1, 6);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('上尉', 4000, 6, 1, 5);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('中尉', 3000, 5, 1, 4);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('少尉', 2000, 4, 1, 3);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('班长', 1000, 3, 1, 2);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('列兵', 0, 2, 1, 1);

基于时间点的恢复介绍：

按照时间点提取sql日志说明：误删除sql语句delete from zx_scores;的binlog日志的生成时间点到下一次DML操作 delete from zx_vote ;记录到binlog日志的时间点。这个时间段的时间点才可以找到需要恢复的sql语句

[root@git-server binlog2sql]# python binlog2sql.py -h227.0.0.1 -P3306 -uadmin -p'admin'  -dzixun3 -tzx_scores --start-file='mysql-bin.000006' --start-datetime='2018-05-23 15:35:59' --stop-datetime='2018-05-23 16:09:59'  -B|awk -F '[;]' '{print $1 ";"}'
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('大将', 29000, 15, 1, 12);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('上将', 24000, 12, 1, 11);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('中将', 19000, 11, 1, 10);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('少将', 14000, 10, 1, 9);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('上校', 9000, 9, 1, 8);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('中校', 6000, 8, 1, 7);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('少校', 5000, 7, 1, 6);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('上尉', 4000, 6, 1, 5);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('中尉', 3000, 5, 1, 4);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('少尉', 2000, 4, 1, 3);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('班长', 1000, 3, 1, 2);
INSERT INTO `zixun3`.`zx_scores`(`titles`, `integral`, `id`, `isdefault`, `icon`) VALUES ('列兵', 0, 2, 1, 1);

直接在mysql中恢复就可以了
