进入 源文件夹下载适用于CentOS/RHEL引导源
# cd /etc/yum.repos.d/
# wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo
安装EPEL ，EPEL是yum的一个软件源,里面包含了许多基本源里没有的软件，因为是centos7所以选择第一句
CentOS/RHEL 7, 64 Bit (x86_64):
# rpm -Uvh http://epel.mirror.net.in/epel/7/x86_64/e/epel-release-7-9.noarch.rpmCentOS/RHEL 6, 64 Bit (x86_64):
# rpm -Uvh http://epel.mirror.net.in/epel/6/x86_64/epel-release-6-8.noarch.rpm
安装VirtualBox5.1相关依赖包
# yum install gcc make patch dkms qt libgomp
# yum install kernel-headers kernel-devel fontforge binutils glibc-headers glibc-devel
特别注意VirtualBox安装需要有准确对应得liunx内核版本，否则出差
yum install VirtualBox-5.1
安装后测执行 VirtualBox 命令，提示报错
VirtualBox
WARNING: The vboxdrv kernel module is not loaded. Either there is no module
available for the current kernel (3.10.0-514.6.1.el7.x86_64) or it failed to
load. Please recompile the kernel module and install it by
sudo /sbin/vboxconfig
You will not be able to start VMs until this problem is fixed.

vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
This system is not currently set up to build kernel modules (system extensions).
Running the following commands should set the system up correctly:
yum install kernel-devel-3.10.0-514.6.1.el7.x86_64
(The last command may fail if your system is not fully updated.)
yum install kernel-devel
vboxdrv.sh: failed: Look at /var/log/vbox-install.log to find out what went wrong.
This system is not currently set up to build kernel modules (system extensions).
Running the following commands should set the system up correctly:
yum install kernel-devel-3.10.0-514.6.1.el7.x86_64
(The last command may fail if your system is not fully updated.)
yum install kernel-devel
There were problems setting up VirtualBox. To re-start the set-up process, run
/sbin/vboxconfig
as root.
提示内核版本不对于，按提示执行
yum install kernel-devel-3.10.0-514.6.1.el7.x86_64
yum install kernel-devel
安装所需内核版本，重装内核可用下面语句
service vboxdrv setup
后后测执行 VirtualBox 命令，出现允许正常标准
