1 检查系统内核版本
[root@centos ~]# uname -a
Linux centos 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:35 EDT 2010 i686 i686 i386 GNU/Linux
2 安装软件环境
yum install gcc
yum install kernel-devel
yum install kernel-headers
注：这步执行后的版kernel-devel和kernel-headers 的版本为
======================================================================================================
Package Arch Version Repository Size
======================================================================================================
Installing:
kernel-devel x86_64 2.6.18-308.16.1.el5 updates 5.7 M
Transaction Summary
======================================================================================================
Install 1 Package(s)
Upgrade 0 Package(s)
3 升级系统内核
注：如果不升级内核的话，那么”kernel-devel和kernel-headers”与kenerl内核的版本不一致在第一步uname -a我们看到内核版本为2.6.18-194.el5
[root@centos ~]# yum install kernel

升级完了内核，现在在来看下内核的版本变更过来了没有
[root@centos ~]# uname -a
Linux centos 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:14 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
还是没有变过来，这里要注意了。升级内核后一定要重启
4 安装软件包
[root@centos ~]# rpm -ivh dkms-2.2.0.3-1.noarch.rpm
Preparing... ########################################### [100%]
1:dkms ########################################### [100%]
[root@centos ~]# rpm -ivh VirtualBox-4.1-4.1.10_76795_rhel5-1.x86_64.rpm
warning: VirtualBox-4.1-4.1.10_76795_rhel5-1.x86_64.rpm: Header V4 DSA signature: NOKEY, key ID 98ab5139
Preparing... ########################################### [100%]
1:VirtualBox-4.1 ########################################### [100%]
注：先要安装dkms在装virtualbox，要不然会报错，会说你缺少依赖包
5 启动virtualbox
[root@centos ~]# /etc/init.d/vboxdrv setup
Stopping VirtualBox kernel modules [确定]
Uninstalling old VirtualBox DKMS kernel modules [确定]
Trying to register the VirtualBox kernel modules using DKMSError! echo
Your kernel headers for kernel 2.6.18-194.el5 cannot be found at
/lib/modules/2.6.18-194.el5/build or /lib/modules/2.6.18-194.el5/source.
[失败]
(Failed, trying without DKMS)
Recompiling VirtualBox kernel modules [失败]
失败了，为么呢？就是内核的原因，都说要重启了，看下grub配置文件
[root@centos ~]# vim /boot/grub/grub.conf
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/sdb6
# initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
initrd /initrd-2.6.18-308.16.1.el5.img
这呢，虽然没重启但是也排在了首位，那么重启下看看
[root@centos ~]# reboot
[root@centos ~]# uname -a
Linux centos 2.6.18-308.16.1.el5 #1 SMP Tue Oct 2 22:01:43 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux
[root@centos ~]# /etc/init.d/vboxdrv setup

看，VirtualBox 起来了
到此，virtualbox安装结束。啥？不知道咋用？问谷老师去。^_^
