这是一篇15年的文章，现在不知还有参考价值没？

我的CentOS是用VirtualBox做的虚拟机，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。

更新内核。

CentOS 6.2对应的kernel默认为2.6.32-220.el6：

# uname -r2.6.32-220.el6.x86_64

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 * epel: mirrors.ustc.edu.cn * rpmforge: mirror.oscc.org.myAvailable PackagesName        : kernel-develArch        : x86_64Version     : 2.6.32 Release     : 279.5.2.el6Size        : 7.6 MRepo        : updatesSummary     : Development package for building kernel modules to match the            : kernelURL         :      : GPLv2Description : This package provides kernel headers and makefiles sufficient to            : build modules against the kernel package.

当前的kernel-devel版本是2.6.32-279.5.2.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。

安装kernel-devel和gcc。

# yum install kernel-devel gcc gcc-c++

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...

安装VBoxLinuxAdditions可能会报错：

$ ./VBoxLinuxAdditions.run  ... ...Building the main Guest Additions module                   [FAILED](Look at /var/log/vboxadd-install.log to find out what went wrong)... ...  $ cat /var/log/vboxadd-install.log /tmp/vbox.0/Makefile.include.header:97: \*\*\* Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make again.  Stop. Creating user for the Guest Additions. Creating udev rule for the Guest Additions kernel module.

可能是内核目录和内核版本不一致造成的：

$ ls /usr/src/kernels/2.6.32-358.6.2.el6.x86_64$ uname -r 2.6.32-358.el6.x86_64

建立一个链接指向内核目录应该就可以解决问题：

$ ls -l /usr/src/kernels/total 4drwxr-xr-x. 22 root root 4096 May 24 17:39 2.6.32-358.6.2.el6.x86_64lrwxrwxrwx.  1 root root   42 May 24 17:38 2.6.32-358.el6.x86_64 -> /usr/src/kernels/2.6.32-358.6.2.el6.x86_64
