  • 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 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)
    mysql>

    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
