查看binlog文件的2種方式

1.使用show binlog events

a.獲取binlog文件列表
mysql> show binary logs;
+------------------+-----------+
| Log_name         | File_size |
+------------------+-----------+
| mysql-bin.000005 |      1288 |
| mysql-bin.000006 |       120 |
+------------------+-----------+
mysql>

b.查看當前正在寫入的binlog文件
mysql> show master status\G;
*************************** 1. row ***************************
             File: mysql-bin.000006
         Position: 120


c.查看指定binlog文件的內容語法：
SHOW BINLOG EVENTS [IN 'log_name'] [FROM pos] [LIMIT [offset,] row_count]

1.演示查看一個二進制文件中所有事務
注：binlog文件其實是由一連串的event組成的一個組，即事務組。
mysql> SHOW BINLOG EVENTS IN 'mysql-bin.000005' \G
*************************** 1. row ***************************  一個row表明一個事務組
   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.演示對一個二進制文件的事務作過濾查詢
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)

2.使用mysqlbinlog查看binlog（轉：http://blog.csdn.net/leshami/article/details/41962243）

a、提取指定的binlog日誌  
# 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日誌  
# mysqlbinlog --start-position="120" --stop-position="332" /opt/data/APP01bin.000001  
 
c、提取指定position位置的binlog日誌並輸出到壓縮文件  
# 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日誌導入數據庫  
# mysqlbinlog --start-position="120" --stop-position="332" /opt/data/APP01bin.000001 | mysql -uroot -p  
 
e、提取指定開始時間的binlog並輸出到日誌文件  
# mysqlbinlog --start-datetime="2014-12-15 20:15:23" /opt/data/APP01bin.000002 --result-file=extra02.sql  
 
f、提取指定位置的多個binlog日誌文件  
# mysqlbinlog --start-position="120" --stop-position="332" /opt/data/APP01bin.000001 /opt/data/APP01bin.000002|more  
 
g、提取指定數據庫binlog並轉換字符集到UTF8  
# mysqlbinlog --database=test --set-charset=utf8 /opt/data/APP01bin.000001 /opt/data/APP01bin.000002 >test.sql  
 
h、遠程提取日誌，指定結束時間   
# 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、遠程提取使用row格式的binlog日誌並輸出到本地文件  
# 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
當bin-log的模式設置爲row時（binlog_format=row），查看執行的sql時也稍微麻煩一點，默認解析出來的結果是這樣的

-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 /*!*/;

徹底看不懂，這時須要添加參數（--base64-output=decode-rows -v）對輸出結果解碼。

-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*/;
