前些天一直在寻找基于linux下的软硬件信息收集工具，虽然使用linux下的一些命令可以收集到所需的信息，但比较繁琐，无意之中发现了Percona Toolkit这个工具，官方地址为http://www.percona.com/software/percona-toolkit/，其实这是一组针对mysql的命令行工具,用来管理 MySQL 和系统任务，源于Aspersa，且看解释Aspersa has become part of Percona Toolkit, and there will be no further development or releases separate from Percona Toolkit. 但用来收集软硬件信息也还是不错的，可以通过官方地址进行下载，另外，相关命令的使用可以参考这里http://aspersa.googlecode.com/svn/html/support.html，

下面在RHEL5.6上面进行测试安装。 安装之前一定要准备这个文件，perl-TermReadKey，这个是不在红帽提供的软件包之中，所以要按照自己的系统类型进行下载（可以通过google搜索）。 另外，我的系统没有安装perl-DBD-MySQL,perl-DBI包，所以这三个要先进行安装，安装完成之后会在/usr/bin产生以pt开头的命令，
