DiskSim的安装过程（二）

上一篇文章http://http://blog.youkuaiyun.com/stormragewang/article/details/33727127 中由于我使用的CentOS位64位版本，在安装完DiskSim后在运行验证程序时出错，由于昨天给老师出去跑腿去了，耽误了一天，今天来记录下我在新系统下安装DiskSim的过程。

我使用的是VrtualBox 搭建的CentOS的虚拟机，具体的安装过程可以参考网上的相关文章

• http://http://blog.youkuaiyun.com/kobe_lzq/article/details/7894718 这篇文章讲解了如何安装CentOS
  
• http://http://blog.sina.com.cn/s/blog_77b9e7010101hmsx.html 这篇文章讲解了如何在虚拟机和主机间共享文件夹

需要注意的是

• VirtualBox的默认虚拟机的配置信息（主要是虚拟硬盘文件等）默认的是安装在C盘的，这样不是很合理，我么最好在安装虚拟机前就在 “管理 -》 全局设定” 中修改一下。

• 在通过  “设备 -》 安装增强功能”   安装完共享文件夹的扩展功能后，我添加共享文件夹的命令如下

[WangZhi@Panda-CentOS ~]$ cd /mnt/
[WangZhi@Panda-CentOS mnt]$ ls
[WangZhi@Panda-CentOS mnt]$ su
Password: 
[root@Panda-CentOS mnt]# mkdir DiskSim
[root@Panda-CentOS mnt]# ls
DiskSim
[root@Panda-CentOS mnt]# mount -t vboxsf DiskSim-Win DiskSim/
[root@Panda-CentOS mnt]# ls
DiskSim
[root@Panda-CentOS mnt]# cd DiskSim/
[root@Panda-CentOS DiskSim]# LS
bash: LS: command not found
[root@Panda-CentOS DiskSim]# ls

[root@Panda-CentOS DiskSim]# 

我的共享文件夹设置如下：

现在就是执行DiskSim的安装了

[WangZhi@Panda-CentOS ~]$ cp -rf /mnt/DiskSim Desktop
[WangZhi@Panda-CentOS ~]$ cd Desktop/DiskSim/
[WangZhi@Panda-CentOS DiskSim]$ ls

编译过程中会出现一些警告信息，可以忽略不管，运行runvalid来验证下

[WangZhi@Panda-CentOS src]$ cd ..
