mysql查看binlog⽂件语法_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下载app
| 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
rows in set (0.00 sec)

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_ 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
-bash-4.1$ /opt/mysql/bin/mysqlbinlog    /opt/mysql/var/mysql-bin.000004|more

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。
