使用 MYSQLBINLOG 來恢復資料
BINLOG就是一個記錄SQL語句的過程，和普通的LOG一樣。不過只是她是二進位制儲存，普通的是十進位制儲存罷了。
1、配置檔案裡要寫的東西：
[mysqld]
log-bin=mysql-bin(名字可以改成自己的，如果不改名字的話，預設是以主機名字命名)
重新啟動MSYQL服務。
二進位制檔案裡面的東西顯示的就是執行所有語句的詳細記錄，當然一些語句不被記錄在內，要了解詳細的，見手冊頁。
2、檢視自己的BINLOG的名字是什麼。
show binlog events;
query result(1 records)
| Log_name | Pos | Event_type | Server_id | End_log_pos | Info |
| yueliangdao_binglog.000001 | 4 | Format_desc | 1 | 106 | Server ver: 5.1.22-rc-community-log, Binlog ver: 4 |
3、我做了幾次操作後，她就記錄了下來。
又一次 show binlog events 的結果。
query result(4 records)
| Log_name | Pos | Event_type | Server_id | End_log_pos | Info |
| yueliangdao_binglog.000001 | 4 | Format_desc | 1 | 106 | Server ver: 5.1.22-rc-community-log, Binlog ver: 4 |
| yueliangdao_binglog.000001 | 106 | Intvar | 1 | 134 | INSERT_ID=1 |
| yueliangdao_binglog.000001 | 134 | Query | 1 | 254 | use `test`; create table a1(id int not null auto_increment primary key, str varchar(1000)) engine=myisam |
| yueliangdao_binglog.000001 | 254 | Query | 1 | 330 | use `test`; insert into a1(str) values ('I love you'),('You love me') |
| yueliangdao_binglog.000001 | 330 | Query | 1 | 485 | use `test`; drop table a1 |
4、用mysqlbinlog 工具來顯示記錄的二進位制結果，然後匯入到文字檔案，為了以後的恢復。
詳細過程如下：
D:\LAMP\MYSQL5\data>mysqlbinlog --start-position=4 --stop-position=106 yueliangd
ao_binglog.000001 > c:\\test1.txt
test1.txt的檔案內容：
/*!40019 SET @@session.max_insert_delayed_threads=0*/;
/*!50003 SET @[email protected]@COMPLETION_TYPE,COMPLETION_TYPE=0*/;
DELIMITER /*!*/;

ROLLBACK/*!*/;
DELIMITER ;
# End of log file
ROLLBACK /* added by mysqlbinlog */;
/*!50003 SET [email protected]_COMPLETION_TYPE*/;
第二行的記錄：
D:\LAMP\MYSQL5\data>mysqlbinlog --start-position=106 --stop-position=134 yuelian
gdao_binglog.000001 > c:\\test1.txt
test1.txt內容如下：

/*!50003 SET @[email protected]@COMPLETION_TYPE,COMPLETION_TYPE=0*/;
DELIMITER /*!*/;

DELIMITER ;
# End of log file
ROLLBACK /* added by mysqlbinlog */;
/*!50003 SET [email protected]_COMPLETION_TYPE*/;
第三行記錄：
D:\LAMP\MYSQL5\data>mysqlbinlog --start-position=134 --stop-position=254 yuelian
gdao_binglog.000001 > c:\\test1.txt
內容：

# End of log file
ROLLBACK /* added by mysqlbinlog */;
/*!50003 SET [email protected]_COMPLETION_TYPE*/;
/*!40019 SET @@session.max_insert_delayed_threads=0*/;
第四行的記錄：
D:\LAMP\MYSQL5\data>mysqlbinlog --start-position=254 --stop-position=330 yuelian
gdao_binglog.000001 > c:\\test1.txt
/*!50003 SET @[email protected]@COMPLETION_TYPE,COMPLETION_TYPE=0*/;

DELIMITER ;
# End of log file
ROLLBACK /* added by mysqlbinlog */;
/*!50003 SET [email protected]_COMPLETION_TYPE*/;
5、檢視這些東西是為了恢復資料，而不是為了好玩。所以我們最中還是為了要匯入結果到MYSQL中。
D:\LAMP\MYSQL5\data>mysqlbinlog --start-position=134 --stop-position=330 yuelian
gdao_binglog.000001 | mysql -uroot -p
或者
D:\LAMP\MYSQL5\data>mysqlbinlog --start-position=134 --stop-position=330 yuelian
gdao_binglog.000001 >test1.txt
進入MYSQL匯入
mysql> source c:\\test1.txt
Query OK, 0 rows affected (0.00 sec)
Query OK, 0 rows affected (0.00 sec)
Database changed
Query OK, 0 rows affected (0.00 sec)
Query OK, 0 rows affected (0.00 sec)
Query OK, 0 rows affected (0.00 sec)
Charset changed
Query OK, 0 rows affected (0.00 sec)
Query OK, 0 rows affected (0.03 sec)
Query OK, 0 rows affected (0.00 sec)
Query OK, 0 rows affected (0.00 sec)
6、檢視資料：
mysql> show tables;
+----------------+
| Tables_in_test |
+----------------+
| a1 |
+----------------+
1 row in set (0.01 sec)
mysql> select * from a1;
+----+-------------+
| id | str |
+----+-------------+
| 1 | I love you |
| 2 | You love me |
+----+-------------+
2 rows in set (0.00 sec)
將一個mysqlbinlog檔案導為sql檔案
cd cd /usr/local/mysql
./mysqlbinlog /usr/local/mysql/data/mysql-bin.000001 > /opt/001.sql
將mysql-bin.000001日誌檔案導成001.sql
可以在mysqlbinlog語句中通過--start-date和--stop-date選項指定DATETIME格式的起止時間
./mysqlbinlog --stop-date="2009-04-10 17:41:28" /usr/local/mysql/data/mysql-bin.000002 > /opt/004.sql
將mysql-bin.000002檔案中截止到2009-04-10 17:41:28的日誌導成004.sql
./mysqlbinlog --start-date="2009-04-10 17:30:05" --stop-date="2009-04-10 17:41:28" /usr/local/mysql/data/mysql-bin.000002 /usr/local/mysql/data/mysql-bin.0000023> /opt/004.sql
----如果有多個binlog檔案，中間用空格隔開，打上完全路徑
./mysqlbinlog --start-date="2009-04-10 17:30:05" --stop-date="2009-04-10 17:41:28" /usr/local/mysql/data/mysql-bin.000002 |mysql -u root -p123456
或者 source /opt/004.sql
將mysql-bin.000002日誌檔案中從2009-04-10 17:30:05到2008-04-10 17:41:28截止的sql語句匯入到mysql中
