今天晚上接到现场电话，说mysql数据库中异常丢失数据，我登陆系统使用mysqlbinlog进行分析日志

[mysql@ezgclient mysqldata]$ mysqlbinlog mysqlbin.000149>/tmp/11_25.txt
ERROR: Error in Log_event::read_log_event(): 'Found invalid event in binary log', data_len: 58, event_type: 19

发现这个错误，第一反应是我使用的mysqlbinlog的版本不正确

[mysql@ezgclient mysqldata]$ whereis  mysqlbinlog
mysqlbinlog: /usr/bin/mysqlbinlog
[mysql@ezgclient mysqldata]$ /usr/bin/mysqlbinlog -V
/usr/bin/mysqlbinlog Ver 3.2 for redhat-linux-gnu at x86_64
[mysql@ezgclient mysqldata]$ /opt/mysql/product/5.1/bin/mysqlbinlog -V
/opt/mysql/product/5.1/bin/mysqlbinlog Ver 3.3 for unknown-linux-gnu at x86_64

通过查询果然发现在默认情况下调用的是系统默认安装的mysql中的mysqlbinlog，因为这个mysqlbinlog的版本和当前的bin_log的版本不能对应起来，所以不能处理，使用对应的mysqlbinlog工作正常

[mysql@ezgclient mysqllog]$ /opt/mysql/product/5.1/bin/mysqlbinlog mysqlbin.000150>/tmp/11_25.txt
[mysql@ezgclient mysqllog]$ more /tmp/11_25.txt
