安装过程：
下载mysqlsla的压缩包：
下载地址在：http://hackmysql.com/mysqlsla
下载之后放置在服务器上：
解压
命令如下：
tar -xzvf mysqlsla-2.03.tar.gz
然后：
cp mysqlsla-2.03/bin/mysqlsla /usr/local/bin
【如果提示“Can’t locate DBI.pm”；执行yum install perl-DBI perl-DBD-MySQL -y 】
然后就可以使用了，
语法如下：
mysqlsla -lt slow slow.log > result.txt
中间出现错误，大致是：Can't locate Time/HiRes.pm
解决方法：
yum -y install perl-Time-HiRes
