The RHEL8 teaching environment is installed on the virtual machine on VMware Workstation

When installing the Red Hat Enterprise Linux 8 teaching environment, students need to install the environment into a virtual machine to practice on their own laptops. VMware Workstation is generally recommended to host the entire teaching environment.

Prepare:

1) Mobile hard disk

2) USB disk above 16G

3) RHEL8 teaching environment software

Step 1: Verify that the teaching environment software is complete

# 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

Step 2: Format the USB stick
 

# lsblk

# umount /dev/sdc1

# cd /mnt/hd/rhel8

# ./rht-usb-8.x-7.r2019052915git14db55b usbmkpart /dev/sdc gpt

Step 5: Make the USB stick bootable

*   This operation will manipulate the MBR of the mounted USB device.   *
   *   If something misleads the tool, IT COULD RENDER YOUR SYSTEM         *
   *   UNBOOTABLE. YOU HAVE BEEN WARNED!   

It is said that it may cause the system to fail to start, what should I do?

This step requires two commands parted and syslinux-extlinux on the system. I don't have syslinux-extlinux on my CentOS 7, so I'll install it.

# yum -y install syslinux-extlinux

Run the command to set the USB as a bootable disk.

# ./rht-usb-8.x-7.r2019052915git14db55b usbmkboot


INFO     Configuration file: /root/.icrm/config.yml

WARNING - You get to keep all the pieces if system becomes unbootable
WARNING - We really mean it - do not cry to us if your system is destroyed

INFO     Using sgdisk to tag bootable /dev/sdc3
INFO     /dev/sdc3: sgdisk set of Legacy BIOS bootable flag OK
INFO     Appear to have successfully made USB bootable.

It just writes a file to /tmp, how could it break my OS? But this is Red Hat's warning, to continue, or to give up? Finally, I pressed y anyway!

everything is normal! ! !

/dev/sdc2 is formatted as vfat and written to /boot/EFI?

Step 6: Copy the course content to a USB stick

or use that

rht-usb-xxx usbadd RHCI*.icmf //Add foundation virtual machine

rht-usb-xxx usbadd RH124*.icmf //Add course RH124

rht-usb-xxx usbadd RH134*.icmf //Add course RH134

rht-usb-xxx usbadd RH294*.icmf //Add course RH294

The above steps will take a long time.

Step 7: Install to a Virtual Machine with the Foundation ISO

There is a difficulty in this step: RHEL 8 / CentOS 8 cannot recognize the hard disk . I also saw that many friends on the Internet corrected by modifying the configuration file of the virtual machine, but I cannot see that option on my virtual machine. And it's actually not that complicated. After the creation is complete, do not start, delete the original hard disk, and recreate a SATA hard disk . VMware Workstation recommends using SCSI hard drives. The configuration is as follows:

Processors: 2 (Virtualization: Check Intel VT-x or AMD-V)

Memory: 8G

Hard disk: 150G (SATA)

USB: Support 3.0 (to mount my USB or mobile hard disk)

CD-ROM: Use the ISO file rhci-foundation-8.0-7.r2019052915gitc76cfec.iso

After the installation interface appears, enter: f0 rh124

Step 8: Add Courses

After the installation is successful, start, and then add the course:

sudo rht-usb courseusb rh134

sudo rht-usb courseusb rh294
