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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | # 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 Publish date: 2019-05-29 15:41:50 type md5sum artifact-name ----------- ------- ----------------------------------------------- content GOODSUM rhel-8.0-x86_64-dvd.iso content GOODSUM foundation-config-8.x-7.r2019052915git14db55b.noarch.rpm content GOODSUM foundation0-config-8.x-7.r2019052915git14db55b.noarch.rpm content GOODSUM redhat-survey-7.x-58.0.noarch.rpm content GOODSUM redhat-training-survey-7-59.4.noarch.rpm content GOODSUM redhat-training-roster-7-59.1.noarch.rpm content GOODSUM rhci-foundation-8.0-7.r2019052915gitc76cfec.iso content GOODSUM rht-usb-8.x-7.r2019052915git14db55b content GOODSUM rht-usb-7.x-6.r2019052915git14db55b content GOODSUM ClassroomSetup-8.x-7.r2019052915git14db55b.txt content GOODSUM ClassroomReset-8.x-7.r2019052915git14db55b.txt content GOODSUM ClassroomTroubleshooting-8.x-7.r2019052915git14db55b.txt content GOODSUM ClassPrep-8.x-7.r2019052915git14db55b.txt ===================================================================== INFO Manifest RHCIfoundation-RHEL80-7.r2019052915-ILT-7-en_US.icmf passed. INFO Verification SUCCEEDED |
第2步：格式化USB盘
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | # 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：
1 2 3 4 | 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。
1 2 3 4 5 6 7 8 9 | # ./rht-usb-8.x-7.r2019052915git14db55b usbformat /dev/sdc3 INFO Configuration file: /root/.icrm/config.yml INFO Formatting USB Partition: /dev/sdc3 Confirm reformatting /dev/sdc3 (y/N) y INFO mkfs.ext4 64-bit support INFO mkfs.ext4 no metadata_csum support 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
