1 檢查系統內核版本
[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 安裝軟件環境
yum install gcc
yum install kernel-devel
yum install kernel-headers
注：這步執行後的版kernel-devel和kernel-headers 的版本爲
======================================================================================================

======================================================================================================
Installing:
kernel-devel x86_64 2.6.18-308.16.1.el5 updates 5.7 M

======================================================================================================
Install 1 Package(s)

3 升級系統內核
注：如果不升級內核的話，那麼”kernel-devel和kernel-headers”與kenerl內核的版本不一致在第一步uname -a我們看到內核版本爲2.6.18-194.el5
[root@centos ~]# yum install kernel

升級完了內核，現在在來看下內核的版本變更過來了沒有
[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
還是沒有變過來，這裏要注意了。升級內核後一定要重啓
4 安裝軟件包
[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：先要安裝dkms在裝virtualbox，要不然會報錯，會說你缺少依賴包
5 啓動virtualbox
[root@centos ~]# /etc/init.d/vboxdrv setup
Stopping VirtualBox kernel modules [確定]
Uninstalling old VirtualBox DKMS kernel modules [確定]
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.
[失敗]
(Failed, trying without DKMS)
Recompiling VirtualBox kernel modules [失敗]
失敗了，爲麼呢？就是內核的原因，都說要重啓了，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
這呢，雖然沒重啓但是也排在了首位，那麼重啓下看看
[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 起來了
到此，virtualbox安裝結束。啥？不知道咋用？問谷老師去。^_^
