Red Hat Enterprise Linux (RHEL) is a Linux Operating System developed by Red Hat. RHEL is generally aimed at the commercial market. Red Hat Enterprise Linux is available for multiple platforms including x86, x86_64, PowerPC, IBM pSeries and IBM System z (Mainframe).

The following Red Hat Installation guide can be used for installing a Red Hat 7.7 GUI with Server configuration with a custom disk and Static IP addressing scheme.

To register and download your evaluation copy of Red Hat Enterprise Linux, simply follow this Link : https://www.redhat.com/wapps/sso/login.html

If you wish to try RHEL 7.7, you can download an evaluation copy giving you a full 30 day free trial (including updates).

Installing RHEL 7.x Server

STEP 1 : To start your installation of RHEL 7.7, highlight the “Install Red Hat Enterprise Linux 7.7” option and press enter. Your installation will now start.

STEP 2 : Select Installation Language

At this screen you will need to choose the language that you would like to use during your installation. In this example, “English”, “English (United States)” has been selected. Once you have made your selection, click on continue in the lower right hand corner of the screen.

STEP 3 : Installation Summary

At this screen various configuration options are available. Any option that is highlighted must be addressed before you can continue with your installation. It is from this screen that you can configure your Localization settings, Security Policy, Software and System settings.

STEP 4 : Date and Time

From this screen you need to choose your geographic location from either the map or from the pull down menu. In this example “Europe” and “Istanbul” have been selected. You can adjust the time and date by clicking on the relevant arrows in the lower left and lower right hand corners of the screen. You may also configure your system to use “NTP” for time synchronisation by clicking on the small gear icon in the upper right corner. (see step below)

STEP 5 : Installation Destination

Once you have selected the option “Automatically Configure Partitioning”, click on the “Done” button in the upper left hand corner of the screen.

STEP 6 : Software Selection

At this screen you can choose which “Base Environment” is to be used for your installation. Several server configurations are available. You should choose the option that best matches your requirements. In this example,

“Server with GUI” has been selected. Any additional “Add-Ons” that are available may be selected from the right hand options panel. In this example, no “Add-Ons” have been selected. Click “Done” to continue with your installation.

STEP 7 : Configure Network and Hostname

At this screen you can enter the “hostname to be used for your server and click on “Configure” to manually configure your network interface(s). To update the screen with the newly entered hostname, click on the “Apply” button. If you do not wish to assign a static IP address to your system and you wish to use “DHCP” for the automatic allocation of an IP address, then you can click on the “OFF/ON” box in the upper right hand corner of the screen.

In this example, we are going to assign a Static IP address. Generally all servers normally require a static IP address. This is an address that is assigned specifically to your server and will not change after a restart/reboot of your system.

Host name in this box enter a unique name to identify your system on your network. In this example, I have entered “rhel07”. Click “Apply” to update.

Click “Configure” to start configuring your network settings.

Next, you should see a “Pop-Up” menu where we are going to add our IP address, Netmask, Gateway and DNS server information. In the following example I will be using the following Network

STEP 8 : Begin Installation

Eğer tüm kurulum hazırlıkları tamamlandıysa Begin Installation seçeneği ile kurulum başlatılır.

STEP 9 : User Account Configuration

The next section of this installation involves defining the root password and creating a new user. Click on each of the highlighted options in turn to enter the requested information. Whilst you are entering the requested details, the installation will continue in the background.

You must specify a root password to be used for the administration of your system. Note, if you supply a weak password, you will be asked to press “Done” twice to confirm you have chosen a weak password! The strength of your password is also indicated.

From this screen you must define the name of a user. In this example I have also chosen the user to be an “Administrator”. Again, if you supply a weak password, you will be asked to confirm this. Once you have supplied the relevant credentials, simply click “Done” to continue with the installation. It is strongly recommended that you use the “default” option of “Require a password to use this account“.

STEP 10 : Installation Continue

At this point your settings will now be displayed and installation will continue.

STEP 11 : RHEL 7 Install Successfully

Red Hat Enterprise Linux has now been successfully installed. Your system needs to be re-booted before you can use it. Click on “Reboot” to finalise your installation. Remember to remove any media from your drives.

STEP 12 : Accepting the License

You must accept the license terms to continue with the installation.

You will need to accept the license terms by checking the “I accept the license agreement” box. Click “Done” to continue now.

The “Finish Configuration” option must be selected to complete RHEL 7 installation.

STEP 13 : Kdump

“Kdump” is a mechanism that will allow in the event of a system crash information to be collected for determining the cause of the crash. In this example, I have chosen to “Disable” kdump.

To disable “kdump”, un-check the “Enable Kdump” option. Now click “Done” to continue with your installation.

STEP 14 : Subscription Management

From this screen, you can register your system with Red Hat. You will not receive any updates without registration. I chose to register later in this setup. Now click “Finish” to continue and restart.

STEP 15 : RHEL 7 Login Screen

If everything was completed successfully, you will see a login screen similar to the one below. Click the name of the user you created earlier and enter the password details.

hope your desktop screen has arrived. Because the installation stages have been successfully completed. Your Red Hat operating system was installed with GUI support. Bon Appetit 🙂
