* 解析出标准SQL
```bash
python binlog2sql.py --host='127.0.0.1' -P3306 -uadmin -p'admin' --stBinFile='mysql-bin.000002'
python binlog2sql.py --host='127.0.0.1' -P3306 -uadmin -p'admin' --start-file='mysql-bin.000002'
```
* 解析出回滚SQL
```bash
python binlog2sql.py --flashback --host='127.0.0.1' -P3306 -uadmin -p'admin' --stBinFile='mysql-bin.000002' --stBinStPos=1240 --enBinFile='mysql-bin.000004' --enBinEnPos=9620
python binlog2sql.py --flashback --host='127.0.0.1' -P3306 -uadmin -p'admin' --start-file='mysql-bin.000002' --start-pos=1240 --end-file='mysql-bin.000004' --end-pos=9620
```
* 主从切换后数据不一致的修复
```bash
1. 取出老master额外的事务；
python binlog2sql.py --popPk --host='10.1.1.1' -P3306 -uadmin -p'admin' --stBinFile='mysql-bin.000002' --stBinStPos=1240 > oldMaster.sql
python binlog2sql.py --popPk --host='10.1.1.1' -P3306 -uadmin -p'admin' --start-file='mysql-bin.000002' --start-pos=1240 > oldMaster.sql
2. 回滚老master额外的事务；
python binlog2sql.py --flashback --host='10.1.1.1' -P3306 -uadmin -p'admin' --stBinFile='mysql-bin.000002' --stBinStPos=1240 | mysql -h10.1.1.1 -P3306 -uadmin -p'admin'
python binlog2sql.py --flashback --host='10.1.1.1' -P3306 -uadmin -p'admin' --start-file='mysql-bin.000002' --start-pos=1240 | mysql -h10.1.1.1 -P3306 -uadmin -p'admin'
3. 在新master重新执行事务；
mysql -h10.1.1.2 -P3306 -uadmin -p'admin' < oldMaster.sql
```
