CentOS 6.5 VirtualBox 安装和常见问题解答

标签：

　　根据公司需求，要安装virtualBox进行服务器的搭建。我这个版本安装选用4.1版本。

为什么呢？我这边的服务器，试过4.2/3、5.0版本，安装成功，以后都是不能正常使用。最后实验4.1版本成功！

1. Change to root User

su -
## OR ##sudo -i

2. Install Fedora or RHEL Repo Files

cd /etc/yum.repos.d/

## CentOS 6.1/6/5.7 and Red Hat (RHEL) 6.1/6/5.7 users

wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo

3. Update latest packages and check your kernel version

Update packages

yum update

Check that that you are running latest installed kernel version
Output of following commands version numbers should match:

rpm -qa kernel |sort |tail -n 1

uname -r

//两个命令下的kernel的版本应该是一致的

Note: If you got kernel update or run older kernel than newest installed then reboot:

reboot

4. Install following dependency packages

CentOS 5 and Red Hat (RHEL) 5 needs EPEL repository, install it with following command:

rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm

yum install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms
 
## PAE kernel users install ##

yum install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-PAE-devel dkms

5. Install VirtualBox Latest Version 4.1 (currently 4.1.8)

yum install VirtualBox-4.1

Note:
This command create automatically vboxusers group and VirtualBox user must be member of that group.
This command also build needed kernel modules.

Rebuild kernel modules with following command:

/etc/init.d/vboxdrv setup
## OR ##
service vboxdrv setup

6. Add VirtualBox User(s) to vboxusers Group

Replace user_name with your own user name or some another real user name.

usermod -a -G vboxusers user_name

7. Start VirtualBox

Use launcher from menu or simply run:

VirtualBox

Troubleshooting

If you have problems with KERN_DIR parameter or your kernel directory is not automatically detected then set KERN_DIR environment variable manually, using following method:

## Current running kernel on Fedora ##

KERN_DIR=/usr/src/kernels/`uname -r`

## Current running kernel on CentOS and Red Hat (RHEL) ##

KERN_DIR=/usr/src/kernels/`uname -r`-`uname -m`

## Fedora example ##

KERN_DIR=/usr/src/kernels/2.6.33.5-124.fc13.i686
 ## CentOS and Red Hat (RHEL) example ##

KERN_DIR=/usr/src/kernels/2.6.18-194.11.1.el5-x86_64
//环境变量的配置要根据实际情况去配置 

## Export KERN_DIR 

##export KERN_DIR

1.安装的时发现没有出现图形化界面，是因为virtualBox默认安装内存大小是512M，而centOS默然要求是528M，所以安装的时候加大内存就可以了。
