1> MySQL的binlog 日志对于生产环境非常有用，任何时间对数据库的修改都会记录在binglog中；当数据发生增删改，创建数据库对象都会记录到binlog中，数据库的复制也是基于binlog进行同步数据；和SQL SERVER 数据库开启完整模式的原理一样，每一次的数据的变动都会记录在案；（对数据库的select,show这些操作不会记录在binlog）下面介绍mysqlbinlog工具查看二进制日志内容；示例 1> 产生新的binlog日志 flush logs 1> 测试数据 create table test1 （id int）; insert into test1 values (1); insert into test1 values (2); insert into test1 values (3); delete from test1 where id=2; 2> 最新的binlog mysqlbinlog.000012 [root@localhost][(none)]> show binlog events in 'mysqlbinlog.000012';
