1.使用show binlog events
a.获取binlog文件列表
mysql> show binary logs;
+------------------+-----------+
| Log_name | File_size |
+------------------+-----------+
| mysql-bin.000005 | 1288 |
| mysql-bin.000006 | 120 |
+------------------+-----------+
mysql>
b.查看当前正在写入的binlog文件
mysql> show master statusG;
*************************** 1. row ***************************
File: mysql-bin.000006
Position: 120
c.查看指定binlog文件的内容语法：
SHOW BINLOG EVENTS [IN 'log_name'] [FROM pos] [LIMIT [offset,] row_count]
1.演示查看一个二进制文件中全部事务
注：binlog文件实际上是由一连串的event组成的一个组，即事务组。
mysql> SHOW BINLOG EVENTS IN 'mysql-bin.000005' G
*************************** 1. row *************************** 一个row代表一个事务组
Log_name: mysql-bin.000005
Pos: 4
Event_type: Format_desc
Server_id: 1
End_log_pos: 120
Info: Server ver: 5.6.29-log, Binlog ver: 4
*************************** 2. row ***************************
Log_name: mysql-bin.000005
Pos: 120
Event_type: Query
Server_id: 1
End_log_pos: 194
Info: BEGIN
2.演示对一个二进制文件的事务做过滤查询
mysql> SHOW BINLOG EVENTS IN 'mysql-bin.000005' FROM 194 LIMIT 2 G;
*************************** 1. row ***************************
Log_name: mysql-bin.000005
Pos: 194
Event_type: Query
Server_id: 1
End_log_pos: 319
Info: use `tpcc`; UPDATE warehouse SET w_ytd = w_ytd + 3232 WHERE w_id = 1
*************************** 2. row ***************************
Log_name: mysql-bin.000005
Pos: 319
Event_type: Query
Server_id: 1
End_log_pos: 458
Info: use `tpcc`; UPDATE district SET d_ytd = d_ytd + 3232 WHERE d_w_id = 1 AND d_id = 3
2 rows in set (0.00 sec)

2.使用mysqlbinlog查看binlog（转：http://blog.csdn.net/leshami/article/details/41962243）
a、提取指定的binlog日志 # mysqlbinlog /opt/data/APP01bin.000001 # mysqlbinlog /opt/data/APP01bin.000001|grep insert /*!40019 SET @@session.max_insert_delayed_threads=0*/; insert into tb values(2,'jack') b、提取指定position位置的binlog日志 # mysqlbinlog --start-position="120" --stop-position="332" /opt/data/APP01bin.000001 c、提取指定position位置的binlog日志并输出到压缩文件 # mysqlbinlog --start-position="120" --stop-position="332" /opt/data/APP01bin.000001 |gzip >extra_01.sql.gz d、提取指定position位置的binlog日志导入数据库 # mysqlbinlog --start-position="120" --stop-position="332" /opt/data/APP01bin.000001 | mysql -uroot -p e、提取指定开始时间的binlog并输出到日志文件 # mysqlbinlog --start-datetime="2014-12-15 20:15:23" /opt/data/APP01bin.000002 --result-file=extra02.sql f、提取指定位置的多个binlog日志文件 # mysqlbinlog --start-position="120" --stop-position="332" /opt/data/APP01bin.000001 /opt/data/APP01bin.000002|more g、提取指定数据库binlog并转换字符集到UTF8 # mysqlbinlog --database=test --set-charset=utf8 /opt/data/APP01bin.000001 /opt/data/APP01bin.000002 >test.sql h、远程提取日志，指定结束时间 # mysqlbinlog -urobin -p -h192.168.1.116 -P3306 --stop-datetime="2014-12-15 20:30:23" --read-from-remote-server mysql-bin.000033 |more i、远程提取使用row格式的binlog日志并输出到本地文件 # mysqlbinlog -urobin -p -P3606 -h192.168.1.177 --read-from-remote-server -vv inst3606bin.000005 >row.sql
3.mysqlbinlog 查看row模式的binlog
当bin-log的模式设置为row时（binlog_format=row），查看执行的sql时也稍微麻烦一点，默认解析出来的结果是这样的 -bash-4.1$ /opt/mysql/bin/mysqlbinlog /opt/mysql/var/mysql-bin.000004|more /*!50530 SET @@SESSION.PSEUDO_SLAVE_MODE=1*/; /*!40019 SET @@session.max_insert_delayed_threads=0*/; /*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/; DELIMITER /*!*/; # at 4 #160614 23:18:20 server id 1 end_log_pos 120 CRC32 0xbb07feb7 Start: binlog v 4, server v 5.6.14-log created 160614 23:18:20 at startup # Warning: this binlog is either in use or was not closed properly. ROLLBACK/*!*/; BINLOG ' PCBgVw8BAAAAdAAAAHgAAAABAAQANS42LjE0LWxvZwAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAA8IGBXEzgNAAgAEgAEBAQEEgAAXAAEGggAAAAICAgCAAAACgoKGRkAAbf+ B7s= '/*!*/;
完全看不懂，这时需要添加参数（--base64-output=decode-rows -v）对输出结果解码。
-bash-4.1$ /opt/mysql/bin/mysqlbinlog --base64-output=decode-rows -v /opt/mysql/var/mysql-bin.000004|more /*!50530 SET @@SESSION.PSEUDO_SLAVE_MODE=1*/; /*!40019 SET @@session.max_insert_delayed_threads=0*/; /*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/; DELIMITER /*!*/; # at 4 #160614 23:18:20 server id 1 end_log_pos 120 CRC32 0xbb07feb7 Start: binlog v 4, server v 5.6.14-log created 160614 23:18:20 at startup # Warning: this binlog is either in use or was not closed properly.
