MYSQL binlog 日志内容查看

记录mysql数据库真正执行更改的所有操作（DML语句），不包含那些没有修改任何数据的语句，不会记录select和show这样的语句。

二进制日志的作用：

1、 可以完成主从复制的功能

2、 进行恢复操作。

数据可以通过binglog日志,使用mysqlbinlog命令，实现基于时间点和位置的恢复操作。

二进制文件用cat,head,或者tail命令是无法看的，需要通过mysqlbinglog 命令查看二进制日志，把日志转换格式后，输出到自定义的文件。查看binglog日志文件：

mysqlbinlog --no-defaults -v -v --base64-output=decode-rows /mydata/mysql/mysql3307/logs/mysql-binlog.000021 /root/mysqlbinlog21.log

含义：-v代表可以查看到的具体执行信息。--base64-output 把二进制文件转换格式以下是在ROW模式下，记录的记忆行的变更情况，变更前以及变更后的内容。修改记录模式为：

set global binlog_format=statement;set global binlog_format=mixed;set global binlog_format=row;
