当mysqlbinlog版本与mysql不一致时可能导致出哪些问题_MySQL

Jun 01, 2016 pm 12:59 PM

首先要确定当前版本是不是mysqlbinlog版本,当不是mysqlbinlog版本时可能会导致出哪些问题,下面通过模拟场景的方法给大家做介绍,希望对大家有所帮助。

看当前mysqlbinlog版本的方法:

mysqlbinlog --version
    mysqlbinlog Ver 3.3 for Linux at x86_64
Copy after login

场景1:mysql服务器为mysql 5.6,要求mysqlbinlog版本为3.4及以上,否则mysqlbinlog解析时会直接报错,之前已经碰到过很多次,但是没有记录具体的报错信息,貌似和position位置不存在的报错信息差不多,后来改用mysqlbinlog 3.4版本以后方可解析;

场景2:今天帮客户做一个db恢复,备份文件是全库备份,恢复却只能恢复某个db到一个特定的时间点。方法如下:mysql加上-o database_name参数执行全备份的sql文件,然后用mysqlbinlog的-d database_name参数解析指定库的binlog文件,期间使用到了mysqlbinlog,mysql server是5.6,mysqlbinlog版本是3.3,结果mysqlbinlog解析并没有报错,执行报错,查看解析出来的binlog有很多乱码,起初以为是字符集的问题,但查了半天也没发现问题。后来才尝试用3.4版本的mysqlbinlog解决了这个问题,类似的乱码如下图

总结:当mysql服务器版本是5.6时,一定切记要使用版本>=3.4的mysqlbinlog

希望以上内容对大家有所帮助。
