CentOS6.3安装VBoxAdditions

CentOS6.3是安装在VirtualBox虚拟机上，安装好以后最好再将VBoxAdditions增强功能装上，主要目的是能够在虚拟机和宿主机之间能够共享文件。

1. 更新内核。CentOS 6.3对应的kernel默认为2.6.32-279.el6.i686：

# uname -r
2.6.32-279.el6.i686
安装增强功能需要kernel-devel包，必须保证kernel-devel和kernel版本的一致。查看软件源中kernel-devel的版本：
]# yum info kernel-develLoaded plugins: fastestmirror, refresh-packagekit, securityLoading mirror speeds from cached hostfile * base: mirrors.163.com * extras: mirrors.163.com * updates: mirrors.163.comAvailable PackagesName        : kernel-develArch        : i686Version     : 2.6.32Release     : 279.19.1.el6Size        : 7.6 MRepo        : updatesSummary     : Development package for building kernel modules to match the            : kernelURL         : http://www.kernel.org/License     : GPLv2Description : This package provides kernel headers and makefiles sufficient to            : build modules against the kernel package.
当前的kernel-devel版本是2.6.32-279.19.1.e16。因此，必须升级kernel：
# yum update kernel
升级完后必须重启系统，新的kernel才能被使用。
 
2. 安装kernel-devel和gcc。
# yum install kernel-devel gcc gcc-c++
 
3. 安装增强功能。进入增强功能光盘根目录，执行Linux下的安装命令：
# ./VBoxLinuxAdditions.run Verifying archive integrity...
