安装iozone on CentOS 7 x64

iozone是一个非常专业的文件系统性能测试开源软件，用法和介绍可以参考如下：

http://www.iozone.org/

http://www.iozone.org/docs/IOzone_msword_98.pdf

使用源码安装，步骤如下：

下载最新的稳定版源码：

http://www.iozone.org/src/current/

wget http://www.iozone.org/src/current/iozone-3-434.src.rpm
rpm -ivh iozone-3-434.src.rpm 
cd ~/rpmbuild/SOURCES
[root@digoal SOURCES]# ll

     --------------------------------------

     fileop [-f X ]|[-l # -u #] [-s Y] [-e] [-b] [-w] [-d <dir>] [-t] [-v] [-h]

     -f #      Force factor. X^3 files will be created and removed.
     -l #      Lower limit on the value of the Force factor.
     -u #      Upper limit on the value of the Force factor.
     -s #      Optional. Sets filesize for the create/write. May use suffix 'K' or 'M'.
     -e        Excel importable format.
     -b        Output best case results.
     -i #      Increment force factor by this increment.
     -w        Output worst case results.
     -d <dir>  Specify starting directory.
     -U <dir>  Mount point to remount between tests.
     -t        Verbose output option.
     -v        Version information.
     -h        Help text.

     The structure of the file tree is:
     X number of Level 1 directories, with X number of
     level 2 directories, with X number of files in each
     of the level 2 directories.

     Example:  fileop 2

             dir_1                        dir_2
            /     \                      /     \ 
      sdir_1       sdir_2          sdir_1       sdir_2
      /     \     /     \          /     \      /     \ 
   file_1 file_2 file_1 file_2   file_1 file_2 file_1 file_2

   Each file will be created, and then Y bytes is written to the file.
