故障案例：mysql5.6下，mysqlbinlog版本不对可能导致的问题_MySQL
查看当前mysqlbinlog版本的方法：mysqlbinlog --version
mysqlbinlog Ver 3.3 for Linux at x86_64
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
