mysqlbinlog 数据恢复
mysqlbinlog 支持三种模式：
row level
缺点：
row level模式下，所有的执行的语句当记录到日志中的时候，都将以每行记录的修改来记录，这样可能会产生大量的日志内容，比如有这样一条update语句：update product set user = ‘b’ id = ‘1’，执行之后，日志中记录的不是这条update语句所对应额事件(MySQL以事件的形式来记录bin-log日志)，而是这条语句所更新的每一条记录的变化情况，这样就记录成很多条记录被更新的很多个事件。自然，bin-log日志的量就会很大。尤其是当执行alter table之类的语句的时候，产生的日志量是惊人的。因为MySQL对于alter table之类的表结构变更语句的处理方式是整个表的每一条记录都需要变动，实际上就是重建了整个表。那么该表的每一条记录都会被记录到日志中。
优点：
row level模式下，bin-log中可以不记录执行的sql语句的上下文相关的信息，仅仅只需要记录那一条记录被修改了，修改成什么样了。所以row level的日志内容会非常清楚的记录下每一行数据修改的细节。且不会出现某些特定情况下的存储过程，或function，以及 trigger的调用和触发无法被正确复制的问题。
Statement Level
缺点
由于他是记录的执行语句，所以，为了让这些语句在slave端也能正确执行，那么他还必须记录每条语句在执行的时候的一些相关信息，也就是上下文信息，以保证所有语句在slave端杯执行的时候能够得到和在master端执行时候相同的结果。另外就是，由于MySQL现在发展比较快，很多的新功能不断 的加入，使MySQL得复制遇到了不小的挑战，自然复制的时候涉及到越复杂的内容，bug也就越容易出现。在statement level下，目前已经发现的就有不少情况会造成MySQL的复制出现问题，主要是修改数据的时候使用了某些特定的函数或者功能的时候会出现，比如：sleep()函数在有些版本中就不能 真确复制，在存储过程中使用了last_insert_id()函数，可能会使slave和master上得到不一致的id等等。由于row level是基于每一行来记录的变化，所以不会出现类似的问题。
优点
statement level下的优点首先就是解决了row level下的缺点，不需要记录每一行数据的变化，减少bin-log日志量，节约IO，提高性能。因为他只需要记录在Master上所执行的语句的细节，以及执行语句时候的上下文的信息。
Mixed
说明
Mixed模式，可以理解为是前两种模式的结合。
Mixed模式下，MySQL会根据执行的每一条具体的sql语句来区分对待记录的日志形式，也就是在Statement和Row之间选择一种。
新版本中的Statment level还是和以前一样，仅仅记录执行的语句。而新版本的MySQL中队row level模式也被做了优化，并不是所有的修改都会以row level来记录，像遇到表结构变更的时候就会以statement模式来记录，如果sql语句确实就是update或者delete等修改数据的语句，那么还是会记录所有行 的变更。
上述配置可以在/etc/my.cnf 下面进行配置,如下：
log-bin=mysql-bin #binlog_format=”STATEMENT” #binlog_format=”ROW” binlog_format=”MIXED
也可以动态修改
mysql> SET SESSION binlog_format = ‘STATEMENT’; mysql> SET SESSION binlog_format = ‘ROW’; mysql> SET SESSION binlog_format = ‘MIXED’; mysql> SET GLOBAL binlog_format = ‘STATEMENT’; mysql> SET GLOBAL binlog_format = ‘ROW’; mysql> SET GLOBAL binlog_format = ‘MIXED’;
配置完成后可使用如下语句查看状态
show variables like ‘%binlog_format%‘;
基于mysqlbinlog 语句（statement）的恢复
确定需要恢复数据的时间和位置
mysqlbinlog mysql-bin.000002 |more
找出需要恢复的时间和位置
使用mysqlbinlog 已确定的时间恢复出语句文件
可能有多个 mysql-bin.00000x 文件 第一个文件需要确定开始时间，最后一个文件需要确定结束时间。
mysqlbinlog --start-date="2016-06-06 12:30:00" --stop-date="2016-06-06 18:00:00" mysql-bin.000002 >rollbak0606_01.sql、
--start-positon="50" //指定从50位置开始
--stop-postion="100"//指定到100位置结束
处理语句文件并恢复
mysqlbinlog中包含了所有库和表的sql语句。如需要区分库可进行过滤：
grep "insert into xxx" rollbak0606_01.sql >>rollbak0606_del.sql
导入处理后的文件
mysql -uroot -p‘xxxx‘ --default-character-set=utf8 < rollbak0606_del.sql
或者
source ‘filePath‘
基于mysqlbinlog 行（row）的恢复
确定恢复数据的时间和位置
和基于语句的方式不同。基于行的binlog 使用mysqlbinlog 查看的时候存在乱码问题无法清晰的确定时间。如下图：
因此要使用
mysqlbinlog --base64-output=decode-rows -v --start-date=‘2016-06-06 14:00:00‘ --stop-date=‘2016-06-06 14:20:00‘ /opt/mysql/log/mysql-bin.000001 >/opt/mysql_bak/mysqlbinlog_0606.sql
--base64-output=decode-rows 基于行的binlog
-v 用于重构基于行的sql
B. 恢复
mysqlbinlog --start-date="2016-06-06 16:30:00" --stop-date="2016-06-06 17:00:00" --start-positon="50" --stop-postion="100" mysql_bin.000001 |mysql -uroot -p123456
--start-positon="50" //指定从50位置开始
--stop-postion="100"//指定到100位置结束
C. 也可以转换为基于语句的复制
这里需要一个perl 脚本。感谢提供脚本的大神。

# 通过mysqlbinlog -v 解析binlog生成可读的sql文件
# 提取需要处理的有效sql

# 注意:
# 表结构与现在的表结构必须相同[谨记]
# 由于row模式是幂等的，并且恢复是一次性，所以只提取sql，不提取BEGIN/COMMIT

INSERT INTO cqdata.cq_herodata SET `id`=23, `serverId`=1, `userId`=2, `tempId`=2, `starArr`=‘way‘, `gemArr`=‘wa‘, `wingArr`=‘way‘, `equipData`=‘way‘, `sex`=2, `combat`=4327896, `recordTime`=‘2016-06-06 15:37:03‘; INSERT INTO cqdata.cq_herodata SET `id`=22, `serverId`=1, `userId`=2, `tempId`=2, `starArr`=‘way‘, `gemArr`=‘wa‘, `wingArr`=‘way‘, `equipData`=‘way‘, `sex`=2, `combat`=4327896, `recordTime`=‘2016-06-06 15:37:03‘; INSERT INTO cqdata.cq_herodata SET `id`=21, `serverId`=1, `userId`=2, `tempId`=2, `starArr`=‘way‘, `gemArr`=‘wa‘, `wingArr`=‘way‘, `equipData`=‘way‘, `sex`=2, `combat`=4327896, `recordTime`=‘2016-06-06 15:37:02‘; INSERT INTO cqdata.cq_herodata SET `id`=20, `serverId`=1, `userId`=2, `tempId`=2, `starArr`=‘way‘, `gemArr`=‘wa‘, `wingArr`=‘way‘, `equipData`=‘way‘, `sex`=2, `combat`=4327896, `recordTime`=‘2016-06-06 15:37:02‘; INSERT INTO cqdata.cq_herodata SET `id`=19, `serverId`=1, `userId`=2, `tempId`=2, `starArr`=‘way‘, `gemArr`=‘wa‘, `wingArr`=‘way‘, `equipData`=‘way‘, `sex`=2, `combat`=4327896, `recordTime`=‘2016-06-06 15:37:01‘; INSERT INTO cqdata.cq_herodata SET `id`=18, `serverId`=1, `userId`=2, `tempId`=2, `starArr`=‘way‘, `gemArr`=‘wa‘, `wingArr`=‘way‘, `equipData`=‘way‘, `sex`=2, `combat`=4327896, `recordTime`=‘2016-06-06 15:37:01‘; INSERT INTO cqdata.cq_herodata SET `id`=17, `serverId`=1, `userId`=2, `tempId`=2, `starArr`=‘way‘, `gemArr`=‘wa‘, `wingArr`=‘way‘, `equipData`=‘way‘, `sex`=2, `combat`=4327896, `recordTime`=‘2016-06-06 15:37:00‘; INSERT INTO cqdata.cq_herodata SET `id`=16, `serverId`=1, `userId`=2, `tempId`=2, `starArr`=‘way‘, `gemArr`=‘wa‘, `wingArr`=‘way‘, `equipData`=‘way‘, `sex`=2, `combat`=4327896, `recordTime`=‘2016-06-06 15:37:00‘; DELETE FROM cqdata.cq_herodata WHERE `id`=23 AND `serverId`=1 AND `userId`=2 AND `tempId`=2 AND `starArr`=‘way‘ AND `gemArr`=‘wa‘ AND `wingArr`=‘way‘ AND `equipData`=‘way‘ AND `sex`=2 AND `combat`=4327896 AND `recordTime`=‘2016-06-06 15:37:03‘; DELETE FROM cqdata.cq_herodata WHERE `id`=22 AND `serverId`=1 AND `userId`=2 AND `tempId`=2 AND `starArr`=‘way‘ AND `gemArr`=‘wa‘ AND `wingArr`=‘way‘ AND `equipData`=‘way‘ AND `sex`=2 AND `combat`=4327896 AND `recordTime`=‘2016-06-06 15:37:03‘; DELETE FROM cqdata.cq_herodata WHERE `id`=21 AND `serverId`=1 AND `userId`=2 AND `tempId`=2 AND `starArr`=‘way‘ AND `gemArr`=‘wa‘ AND `wingArr`=‘way‘ AND `equipData`=‘way‘ AND `sex`=2 AND `combat`=4327896 AND `recordTime`=‘2016-06-06 15:37:02‘;
`insert into XXX` 实际上为删除了该条记录。`delete from XXX ` 实际为插入了这条语句。对文件按照库名表名进行处理。导入mysql即可按照要求恢复数据。
