MySQL查看binlog格式_查看binlog文件的2种方式

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 status\G;

*************************** 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 /*!*/;

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
