txt脚本的名字要改名为pl
使用方式：
./Mysql_slow_log_parser.pl /data/mysqldata/3306/data/zsd-slow.log
之前zsd-slow.log的内容：
/usr/local/mysql55/bin/mysqld, Version: 5.5.25-log (Source distribution). started with:
Tcp port: 3306 Unix socket: /data/mysqldata/3306/mysql.sock

insert into t1 select * From t1;
之后输出的内容：

这个脚本可以很好的汇总和分析慢查询日志，晚上写个定时的脚本，输出发送邮件给自己，可以很好的查看，Mysql服务器慢查询的问题。
