my2sql 安装使用

官方github

https://github.com/liuhr/my2sql

1、安装

本想用源码安装，但一直报错，后来直接下载的二进制文件

wget https://raw.githubusercontent.com/liuhr/my2sql/master/releases/centOS_release_7.x/my2sql
chmod +x my2sql 


./my2sql

2、使用

语法和 binlog2sql 类似，不过有一些binlog2sql上的bug，在这个软件中没有。

比如timestamp(3)问题：

分析在线binlog，正向解析SQL

./my2sql -user root -password c123456 -host 127.0.0.1 -port 3357 -mode repl -work-type 2sql -start-file mysql-bin.000038 -start-datetime "2020-07-16 10:20:00" -output-dir ./tmpdir

分析在线binlog，生成回滚SQL

./my2sql -user root -password c123456 -host 127.0.0.1 -port 3357 -mode repl -work-type rollback -start-file mysql-bin.000038 -start-datetime "2020-07-16 10:20:00" -output-dir ./tmpdir

正向解析的SQL

root@ip-172-31-30-45:~/czg/tmpdir# cat forward.38.sql 
UPDATE `ceshi`.`t1` SET `sj`='2022-01-17 10:18:18.188' WHERE (`c1`='a' AND `c2`='b' AND `sj`='2022-01-17 09:41:22.451');
#解析的逆向SQL
root@ip-172-31-30-45:~/czg/tmpdir# cat rollback.38.sql 
UPDATE `ceshi`.`t1` SET `sj`='2022-01-17 09:41:22.451' WHERE (`c1`='a' AND `c2`='b' AND `sj`='2022-01-17 10:18:18.188');

分析已经离线binlog，生成回滚SQL

./my2sql -user root -password c123456 -host 127.0.0.1 -port 3357 -mode file -work-type 2sql -local-binlog-file /usr/local/mysql57/data/mysql-bin.000038 -start-file /usr/local/mysql57/data/mysql-bin.000038  -start-datetime "2020-07-16 10:20:00" -output-dir ./tmpdir
