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。 查看此工具的参数说明介绍请参考: https://github.com/danfengcao/binlog2sql 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;
