How to install Red Hat 9 step by step

Red Hat En­ter­prise Linux 9 can be installed in just a few simple steps. Once the system re­quire­ments are met, you can configure the necessary settings using the con­ve­nient in­stal­la­tion summary.

The new RHEL

Red Hat En­ter­prise Linux (or RHEL for short) has been regarded as one of the best Linux dis­tri­b­u­tions for companies since its initial release in 2002. Over time, the pro­pri­etary platform has become the market leader in this segment. In addition to security, stability and flex­i­bil­i­ty, RHEL is par­tic­u­lar­ly im­pres­sive due to its com­pat­i­bil­i­ty with numerous software packages.

RHEL 9 debuted on May 17, 2022, and will be fully supported through 2027. This version in­cor­po­rates OpenSSL 3, boasts enhanced loading speeds, includes Wireguard VPN, and by default, enables Link Time Op­ti­miza­tion (LTO) in userspace. The version was created on CentOS Stream for the first time. Other new features include automated updates for Container and rollbacks, improved security features such as Integrity Mea­sure­ment Ar­chi­tec­ture (IMA) and new options for analyzing your own data streams and workloads.

In the following sections, we will explain step by step how to install RHEL 9 and which re­quire­ments must be met.

What are the re­quire­ments for in­stalling RHEL 9?

To install Red Hat En­ter­prise Linux 9, you’ll need a minimum of one CPU with a speed of 1 gigahertz. However, it is rec­om­mend­ed to use two CPUs. Your system should have at least 2 gigabytes of RAM, and you should allocate a minimum of 20 gigabytes of hard drive space. The simplest in­stal­la­tion method is via a USB stick with at least 11 gigabytes of capacity, though other storage media are also possible.

Start by down­load­ing the RHEL 9 ISO file from the official Red Hat website and save it to a USB drive. Al­ter­na­tive­ly, you can mount the ISO to a virtual drive. After this, you can proceed with the RHEL 9 in­stal­la­tion.

How to install Red Hat En­ter­prise Linux 9

1. Attach the in­stal­la­tion media you created or mount the down­loaded ISO file, then restart the machine where you want to install Red Hat En­ter­prise Linux 9.

2. In the starting in­stal­la­tion dialog, select the Install Red Hat En­ter­prise Linux 9.x option and confirm with [Enter].

3. The dis­tri­b­u­tion menu will now appear and you will be asked to select the language for the in­stal­la­tion. Click on the desired option and then Continue.

6. Under System you will find the item In­stal­la­tion Target. Here you configure the par­ti­tions and specify where the system should be stored. Al­ter­na­tive­ly, you can let the Red Hat Install Manager do the par­ti­tion­ing au­to­mat­i­cal­ly. Confirm your selection again with Done.
