  • ERROR: Error in Log_event::read_log_event(): 'read error', data_len: 438, event_type: 2

    分析从库1062问题,解析从库binlog日志,报错如下
    [root@xxxdb0402 tmp]# mysqlbinlog mysql-bin.004271 > 4.log
    ERROR: Error in Log_event::read_log_event(): 'read error', data_len: 438, event_type: 2
    [root@xxxdb0402 tmp]# grep  'rding' 4.log > rd4.log
    [root@xxxdb0402 tmp]# ll rd4.log
    -rw-r--r-- 1 root root 0 Sep  3 17:50 rd4.log
    空的,第四个日志没有录入操作


    奇怪报错了,google之,3种方案
    1 写全路径
    [root@xxxdb0402 tmp]# /opt/mysql/product/5.5.25a/bin/mysqlbinlog mysql-bin.004271 > 4.log
    ERROR: Error in Log_event::read_log_event(): 'read error', data_len: 438, event_type: 2
    [root@xxxdb0402 tmp]# whereis  mysqlbinlog
    mysqlbinlog: /usr/bin/mysqlbinlog
    [root@xxxdb0402 tmp]# /usr/bin/mysqlbinlog mysql-bin.004271 > 4.log
    /usr/bin/mysqlbinlog: Character set '#45' is not a compiled character set and is not specified in the '/usr/share/mysql/charsets/Index.xml' file
    ERROR: Error in Log_event::read_log_event(): 'read error', data_len: 438, event_type: 2


    2 加-f强制解析
    [root@xxxdb0402 tmp]# mysqlbinlog -f mysql-bin.004271 > 4.log
    ERROR: Error in Log_event::read_log_event(): 'read error', data_len: 438, event_type: 2


    3 这个copy过来的日志的时候,db正往日志里面写数据呢,从新copy下binlog到/tmp下。
    那就重新copy一次binlog,再解析
    [root@xxxdb0402 tmp]# cp /mysqldata/data/mysql-bin.004271 /tmp/
    cp: overwrite `/tmp/mysql-bin.004271'? y
    [root@xxxdb0402 tmp]# /opt/mysql/product/5.5.25a/bin/mysqlbinlog mysql-bin.004271 > 4.log
    ERROR: Error in Log_event::read_log_event(): 'read error', data_len: 438, event_type: 2

    3种反感都报一样的错误。Mysql版本5.5.25a。linux环境centos6.0


    这个问题如何搞定,比较诡异?
