Vagrant使用VirtualBox实现虚拟化。
一、搭建编译环境
安装VirtualBox，需要安装内核编译环境，并且需要安装dkms，请执行以下命令
sudo yum update
sudo yum install -y epel-release
sudo yum install -y wget
sudo yum install -y kernel kernel-headers kernel-devel
sudo yum install -y dkms
二、安装Virtualbox
# The VirtualBox provider is compatible with VirtualBox versions 4.0.x, 4.1.x, 4.2.x, 4.3.x, 5.0.x, 5.1.x, and 5.2.x.
cd /etc/yum.repos.d
wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo
yum install -y VirtualBox-5.0.x86_64
如需更改Virtualbox 虚拟机的存储目录，请执行
mkdir /home/VirtualBox_VMs
VBoxManage setproperty machinefolder /home/VirtualBox_VMs
三、安装Vagrant
