Red Hat has finally released its most awaited OS RHEL 9 on 22th may 2019. RHEL 9 is based on fedora 28 distribution and UNIX operating system kernel version 4.18. One of the necessary key options in RHEL eight is that it’s introduced “Application Streams” that permits developers tools, frameworks and languages to be updated frequently while not impacting the core resources of base OS. In different words, application streams can help to segregate the users area packages from OS Kernel area.

Apart from this, there are several new options that are noticed in RHEL 9 like:

  • XFS File system supports copy-on-write of file extents
  • Introduction of Stratis filesystem, Buildah, Podman, and Skopeo
  • Yum utility is based on DNF
  • Chrony replace NTP.

  • OpenSSL 1.1.1 & TLS 1.3 support
  • PHP 7.2
  • iptables replaced by nftables

Minimum System Requirements for RHEL 9:

  • 4 GB RAM
  • 20 GB unallocated disk space

Note: RHEL 8 supports the following architectures:

  • AMD or Intel x86 64-bit

Red Hat Enterprise Linux (RHEL) 8 Installation Steps with Screenshots

Step:1) Download Red Hat Enterprise Linux (RHEL) 9.0 ISO file

Download RHEL 9 iso file from its official website(Red hat),

I am assuming you have the active subscription on redhat if not then register yourself for evaluation and then download ISO file

Step:2) Create Installation bootable media (USB or DVD)

Once you have downloaded RHEL 8.0 ISO file, make it bootable by burning it either into a USB drive or DVD. Reboot the target system where you want to install RHEL 8 and then go to its bios settings and set the boot medium as USB or DVD,

Step:3) Choose “Install Red Hat Enterprise Linux 8.0” option

When the system boots up with installation media (USB or DVD), we will get the following screen, choose “Install Red Hat Enterprise Linux 8.0” and hit enter button,

To define the installation disk and partition scheme for RHEL 8.0, click on “Installation Destination” option,

Click on Done

As we can see I have around 60 GB free disk space on sda drive, I will be creating following customize lvm based partitions on this disk,

  • /boot        =  2GB  (xfs file system)
  • /                =  20 GB (xfs file system)
  • /var          =  10 GB (xfs file system)
  • /home      =  15 GB (xfs file system)
  • /tmp         =  5 GB (xfs file system)
  • Swap         = 2 GB (xfs file system)

Note: If you don’t want to create manual partitions then select “Automatic” option from Storage Configuration Tab

Let’s create our first partition as /boot of size 2 GB, Select LVM(Logical Volume Management) as mount point partitioning scheme and then click on + “plus” symbol, 

Click on “Add mount point

To create next partition as / of size 20 GB, click on + symbol  and specify the details as shown below,

Now onward all partitions will be part of Volume Group “VolGrp

Similarly we create next three partitions /home, /var and /tmp of size 15GB, 10 GB and 5 GB respectively

/home partition:

/var partition:

/tmp partition:

Now finally we create last partition as swap of size of 2 GB, 

Click on “Add mount point”

Once you are done with partition creations, click on Done on Next screen button, example is shown below

In the next window, choose “Accept Changes

Step:6) Select Software Packages and Choose Security Policy and System purpose

After accepting the changes in above step, we will be redirected to installation summary window.

By default, installer will select “Server with GUI” as software packages and if you want to change it then click on “Software Selection” option and choose your preferred “Basic Environment Section

Click on Done
