Centos7安装安装增强功能包VBoxLinuxAdditions和共享本机文件夹

因为只安装了命令行，没有使用图形界面，安装增强包出错，提示：centos未能加载虚拟光盘 C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions\VBoxGuestAdditions.iso

安装wget后，从 http://download.virtualbox.org/virtualbox/6.0.10/ 下载VBoxGuestAdditions_6.0.10.iso

#wget http://download.virtualbox.org/virtualbox/6.0.10/VBoxGuestAdditions_6.0.10.iso

然后挂载虚拟光驱：

#mkdir /media/cdrom

#mount VBoxGuestAdditions_6.0.10.iso / media/cdrom

#cd /media/cdrom

安装epel源，否则bzip2无法安装，步骤如下：

#yum -y install epel-release

#yum install perl dkms bzip2

准备工作做完了，准备安装增强包：

[root@localhost cdrom]# ./VBoxLinuxAdditions.run

到virtualbox设置下共享，发现共享已经OK。
