Mysqlbinlog 數據恢復
mysqlbinlog 支持三種模式：
row level
缺點：
row level模式下，所有的執行的語句當記錄到日誌中的時候，都將以每行記錄的修改來記錄，這樣可能會產生大量的日誌內容，比如有這樣一條update語句：update product set user = ‘b’ id = ‘1’，執行之後，日誌中記錄的不是這條update語句所對應額事件(MySQL以事件的形式來記錄bin-log日誌)，而是這條語句所更新的每一條記錄的變化情況，這樣就記錄成很多條記錄被更新的很多個事件。自然，bin-log日誌的量就會很大。尤其是當執行alter table之類的語句的時候，產生的日誌量是驚人的。因爲MySQL對於alter table之類的表結構變更語句的處理方式是整個表的每一條記錄都需要變動，實際上就是重建了整個表。那麼該表的每一條記錄都會被記錄到日誌中。
優點：
row level模式下，bin-log中可以不記錄執行的sql語句的上下文相關的信息，僅僅只需要記錄那一條記錄被修改了，修改成什麼樣了。所以row level的日誌內容會非常清楚的記錄下每一行數據修改的細節。且不會出現某些特定情況下的存儲過程，或function，以及 trigger的調用和觸發無法被正確複製的問題。
Statement Level
缺點
由於他是記錄的執行語句，所以，爲了讓這些語句在slave端也能正確執行，那麼他還必須記錄每條語句在執行的時候的一些相關信息，也就是上下文信息，以保證所有語句在slave端杯執行的時候能夠得到和在master端執行時候相同的結果。另外就是，由於MySQL現在發展比較快，很多的新功能不斷 的加入，使MySQL得複製遇到了不小的挑戰，自然複製的時候涉及到越複雜的內容，bug也就越容易出現。在statement level下，目前已經發現的就有不少情況會造成MySQL的複製出現問題，主要是修改數據的時候使用了某些特定的函數或者功能的時候會出現，比如：sleep()函數在有些版本中就不能 真確複製，在存儲過程中使用了last_insert_id()函數，可能會使slave和master上得到不一致的id等等。由於row level是基於每一行來記錄的變化，所以不會出現類似的問題。
優點
statement level下的優點首先就是解決了row level下的缺點，不需要記錄每一行數據的變化，減少bin-log日誌量，節約IO，提高性能。因爲他只需要記錄在Master上所執行的語句的細節，以及執行語句時候的上下文的信息。
Mixed
說明
Mixed模式，可以理解爲是前兩種模式的結合。
Mixed模式下，MySQL會根據執行的每一條具體的sql語句來區分對待記錄的日誌形式，也就是在Statement和Row之間選擇一種。
新版本中的Statment level還是和以前一樣，僅僅記錄執行的語句。而新版本的MySQL中隊row level模式也被做了優化，並不是所有的修改都會以row level來記錄，像遇到表結構變更的時候就會以statement模式來記錄，如果sql語句確實就是update或者delete等修改數據的語句，那麼還是會記錄所有行 的變更。
上述配置可以在/etc/my.cnf 下面進行配置,如下：
log-bin=mysql-bin #binlog_format=”STATEMENT” #binlog_format=”ROW” binlog_format=”MIXED
也可以動態修改
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’;
配置完成後可使用如下語句查看狀態
show variables like '%binlog_format%';
基於mysqlbinlog 語句（statement）的恢復
確定需要恢復數據的時間和位置
![wKioL1dVP2OTPLbiAABirCGXPRc654.png-wh_50]( "QQ截圖20160606171115.png")
mysqlbinlog mysql-bin.000002 |more
找出需要恢復的時間和位置
使用mysqlbinlog 已確定的時間恢復出語句文件
可能有多個 mysql-bin.00000x 文件 第一個文件需要確定開始時間，最後一個文件需要確定結束時間。
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" //指定從50位置開始
--stop-postion="100"//指定到100位置結束
處理語句文件並恢復
mysqlbinlog中包含了所有庫和表的sql語句。如需要區分庫可進行過濾：
grep "insert into xxx" rollbak0606_01.sql >>rollbak0606_del.sql
導入處理後的文件
mysql -uroot -p'xxxx' --default-character-set=utf8 < rollbak0606_del.sql
或者
source 'filePath'
基於mysqlbinlog 行（row）的恢復
確定恢復數據的時間和位置
和基於語句的方式不同。基於行的binlog 使用mysqlbinlog 查看的時候存在亂碼問題無法清晰的確定時間。如下圖：
![wKioL1dVR6mxFWp3AAB-AyWwJKw126.png-wh_50]( "4647.png")
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 基於行的binlog
-v 用於重構基於行的sql
B. 恢復
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" //指定從50位置開始
--stop-postion="100"//指定到100位置結束
C. 也可以轉換爲基於語句的複製
