安装Red Hat Enterprise Linux 8教学环境时，学员们都需要将这个环境安装到虚拟机中，以便在自己的笔记本电脑上练习使用。一般推荐使用VMware Workstation来托管整个教学环境。
准备：
1）移动硬盘
2）16G以上的USB盘
3）RHEL8教学环境软件
第1步：校验教学环境软件是否完整
# yum install -y http://mirror.centos.org/centos/8/BaseOS/x86_64/os/Packages/python3-pyyaml-3.12-12.el8.i686.rpm
# ./rht-usb-8.x-7.r2019052915git14db55b verify RHCIfoundation-RHEL80-7.r2019052915-ILT-7-en_US.icmf
Verifying manifest file RHCIfoundation-RHEL80-7.r2019052915-ILT-7-en_US.icmf

第2步：格式化USB盘
# lsblk
# umount /dev/sdc1
# cd /mnt/hd/rhel8
# ./rht-usb-8.x-7.r2019052915git14db55b usbmkpart /dev/sdc gpt
INFO Configuration file: /root/.icrm/config.yml
INFO Partitioning USB Device: /dev/sdc
Confirm gpt partitioning /dev/sdc (y/N) y
Wipe existing partitioning of /dev/sdc (y/N) y
INFO /dev/sdc: zap partitions OK
INFO /dev/sdc: wipe partitions OK
INFO /dev/sdc: partitioning OK
INFO /dev/sdc3: apparent RHTINST partition
INFO Now run usbformat of /dev/sdc3
INFO Appear to have properly partitioned USB device.
查看一下，发现上述命令将我这个64G的USB盘分成3个区，如下：
sdc 8:32 1 60G 0 disk
├─sdc1 8:33 1 1M 0 part
├─sdc2 8:34 1 200M 0 part
└─sdc3 8:35 1 59.8G 0 part 将第3个分区格式化。
# ./rht-usb-8.x-7.r2019052915git14db55b usbformat /dev/sdc3
INFO Configuration file: /root/.icrm/config.yml
INFO Formatting USB Partition: /dev/sdc3

INFO /dev/sdc3: format OK
INFO Appear to have properly formatted USB device.
第3步：将Foundation虚拟机拷贝到USB盘上
# ./rht-usb-8.x-7.r2019052915git14db55b usbadd RHCIfoundation-RHEL80-7.r2019052915-ILT-7-en_US.icmf
