BINLOG就是一个记录SQL语句的过程，和普通的LOG一样。不过只是她是二进制存储，普通的是十进制存储罢了。
1、配置文件里要写的东西：
[mysqld]
log-bin=mysql-bin(名字可以改成自己的，如果不改名字的话，默认是以主机名字命名)
重新启动MSYQL服务。
二进制文件里面的东西显示的就是执行所有语句的详细记录，当然一些语句不被记录在内，要了解详细的，见手册页。
2、查看自己的BINLOG的名字是什么。
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、我做了几次操作后，她就记录了下来。
又一次 show binlog events 的结果。
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 工具来显示记录的二进制结果，然后导入到文本文件，为了以后的恢复。
详细过程如下：
D:LAMPMYSQL5data>mysqlbinlog --start-position=4 --stop-position=106 yueliangd
ao_binglog.000001 > c:\test1.txt
test1.txt的文件内容：
/*!40019 SET @@session.max_insert_delayed_threads=0*/;
/*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/;
DELIMITER /*!*/;

ROLLBACK/*!*/;
DELIMITER ;
# End of log file
ROLLBACK /* added by mysqlbinlog */;
/*!50003 SET COMPLETION_TYPE=@OLD_COMPLETION_TYPE*/;
第二行的记录：
D:LAMPMYSQL5data>mysqlbinlog --start-position=106 --stop-position=134 yuelian
gdao_binglog.000001 > c:\test1.txt
test1.txt内容如下：
/*!40019 SET @@session.max_insert_delayed_threads=0*/;
/*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/;
DELIMITER /*!*/;

DELIMITER ;
# End of log file
ROLLBACK /* added by mysqlbinlog */;
/*!50003 SET COMPLETION_TYPE=@OLD_COMPLETION_TYPE*/;
第三行记录：
D:LAMPMYSQL5data>mysqlbinlog --start-position=134 --stop-position=254 yuelian
gdao_binglog.000001 > c:\test1.txt
内容：
/*!40019 SET @@session.max_insert_delayed_threads=0*/;

# End of log file
ROLLBACK /* added by mysqlbinlog */;
/*!50003 SET COMPLETION_TYPE=@OLD_COMPLETION_TYPE*/;
/*!40019 SET @@session.max_insert_delayed_threads=0*/;
第四行的记录：
D:LAMPMYSQL5data>mysqlbinlog --start-position=254 --stop-position=330 yuelian
gdao_binglog.000001 > c:\test1.txt
/*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/;

DELIMITER ;
# End of log file
ROLLBACK /* added by mysqlbinlog */;
/*!50003 SET COMPLETION_TYPE=@OLD_COMPLETION_TYPE*/;
5、查看这些东西是为了恢复数据，而不是为了好玩。所以我们最中还是为了要导入结果到MYSQL中。
D:LAMPMYSQL5data>mysqlbinlog --start-position=134 --stop-position=330 yuelian
gdao_binglog.000001 | mysql -uroot -p
或者
D:LAMPMYSQL5data>mysqlbinlog --start-position=134 --stop-position=330 yuelian
gdao_binglog.000001 >test1.txt
进入MYSQL导入
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、查看数据：
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)
将一个mysqlbinlog文件导为sql文件
cd cd /usr/local/mysql
./mysqlbinlog /usr/local/mysql/data/mysql-bin.000001 > /opt/001.sql
./mysqlbinlog /usr/local/mysql/data/mysql-bin.000001 > /opt/001.sql
将mysql-bin.000001日志文件导成001.sql
可以在mysqlbinlog语句中通过--start-date和--stop-date选项指定DATETIME格式的起止时间
./mysqlbinlog --stop-date="2009-04-10 17:41:28" /usr/local/mysql/data/mysql-bin.000002 > /opt/004.sql
将mysql-bin.000002文件中截止到2009-04-10 17:41:28的日志导成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
----如果有多个binlog文件，中间用空格隔开，打上完全路径
./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
将mysql-bin.000002日志文件中从2009-04-10 17:30:05到2008-04-10 17:41:28截止的sql语句导入到mysql中
