Linux下如何安装虚拟机软件VirtualBox

VirtualBox号称是最强的免费虚拟机软件，它不仅具有丰富的特色，而且性能也很优异。它简单易用，可虚拟的系统包括Windows、[Mac OS X]、Linux、OpenBSD、Solaris、IBM OS2甚至Android等操作系统。

1. 切换ROOT用户

su -## 或者 ##sudo -i

2. 安装Fedora或者RHEL仓库索引文件

cd /etc/yum.repos.d/## Fedora 26/25/24/23/22/21/20/19/18/17/16 userswget http://download.virtualbox.org/virtualbox/rpm/fedora/virtualbox.repo## CentOS 7.4/6.9 跟 Red Hat (RHEL) 7.4/6.9 userswget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo

3. 更新包，更新内核

## Fedora 26/25/24/23/22 ##dnf update## Fedora 21/20/19/18/17/16 跟 CentOS/RHEL 7/6/5 ##yum update

4. 检查内核是否成功更新

rpm -qa kernel |sort -V |tail -n 1uname -r

5. 重启并选择更新后的内核版本

reboot

6. 安装依赖包

## CentOS 7 跟 RHEL 7 ##rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm## CentOS 6 跟 RHEL 6 ##rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm## CentOS 5 跟 RHEL 5 ##rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-5.noarch.rpm## Fedora 26/25/24/23/22 ##dnf install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms## Fedora 21/20/19/18/17/16 and CentOS/RHEL 7/6/5 ##yum install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms## PAE kernel users install #### Fedora 24/23/22 ##dnf install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-PAE-devel dkms## Fedora 21/20/19/18/17/16 and CentOS/RHEL 7/6/5 ##yum install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-PAE-devel dkms

7. 安装VirtualBox版本，最新 Version 5.1 (当前 5.1.28)

## Fedora 26/25/24/23/22 ##dnf install VirtualBox-5.1## Fedora 21/20/19/18/17/16/15/14 and CentOS/RHEL 7/6/5 ##yum install VirtualBox-5.1

8. 重新编译内核模块

## Fedora 26/25/24/23/22/21/20/19 and CentOS/RHEL 7 ##/usr/lib/virtualbox/vboxdrv.sh setup## Fedora 18/17/16 and CentOS/RHEL 6/5 ##/etc/init.d/vboxdrv setup## 或者 ##service vboxdrv setup

9. 添加用户到VirtualBox用户组

usermod -a -G vboxusers 用户名

启动VirtualBox

VirtualBox

10. 故障排除

如果有KERN_DIR参数有问题或你的内核目录没有自动检测到，请手动设置KERN_DIR环境变量，使用以下方法：

## 当前运行的内核是 Fedora ##KERN_DIR=/usr/src/kernels/`uname -r`## 当前运行的内核是 CentOS 跟 Red Hat (RHEL) ##KERN_DIR=/usr/src/kernels/`uname -r`-`uname -m`## 例如 Fedora ##KERN_DIR=/usr/src/kernels/2.6.33.5-124.fc13.i686## 例如 CentOS 跟 Red Hat (RHEL) ##KERN_DIR=/usr/src/kernels/2.6.18-194.11.1.el5-x86_64## 导出变量 KERN_DIR ##export KERN_DIR
