This section provides a brief overview of the steps for installing Red Hat Enterprise Linux. Detailed instructions can be found in the Red Hat Enterprise Linux Installation Guide.
There are a few key steps to remember during the installation process:
-
You will need to select an Installation destination, which is the disk or partition(s) where the software will be installed. The disk or partition(s) you select will be overwritten. Make sure you understand your selection before starting the installation to avoid accidental data loss.
-
You should configure networking under Network and host name before starting the installation. You will need access to the Internet to complete registration and download additional software. The network can be configured after the system is installed. However, the steps are more straightforward during installation.
-
Select Server with a GUI under Software Selection so the system will boot into the full graphical environment after installation. By default, Red Hat Enterprise Linux Server will not install a graphical desktop.
-
Create your primary user account during installation: After the installation begins, you will be instructed to set a password for the root account and be given the opportunity to create a regular user account. You should create a user before the installation process completes. The regular user will be your primary login for development. The root account should only be used for system administration tasks. If you don’t create a user before the installation completes, you will need to reboot and then log in as root to create user accounts.
-
Start the system from the bootable disk and select Install Red Hat Enterprise Linux.
-
Select your preferred language and keyboard layout to use during installation.
-
Under Localization review the settings and make any necessary changes for date and time, language, and keyboard layout. Note: The Done button to return to the Installation summary screen is located in the upper left corner of the screen.
-
Perform the follow steps to make your software selection:
-
Click Software selection.
-
On the next screen, under Software selection, in the Base environment list on the left, select Server with GUI.
-
In the list Add-ons for selected environment on the right, select Development tools.
-
Click the Done button. Note: After returning to the Installation summary screen it will take several seconds to validate your choices.
-
-
Click Installation destination to specify which disk or partition(s) to install the software on. Note: It is important that you understand the choices that you are making in this section to avoid accidental data loss. It is strongly recommended that you read the Installation Destination section of the the Red Hat Enterprise Linux Installation Guide. The installation destination should be at least 16 GB or larger to accommodate the OS, graphical desktop, and development tools.
-
Click Network & host name to configure the network. If the system has more than one network adapter, select it from the list on the left. Then click the On/Off button on the right to enable the network adapter. Click Configure to review and/or change the default settings for the network adapter. Optionally, set a Host name for the system. Before leaving this screen, make sure there is at least one network adapter enabled with the switch in the On position. A network connection will be required to register the system and download system updates.
-
Click KDump to disable KDump and free up memory. Click the box next to Enable kdump so that it is no longer checked. Then click Done.
-
Click the Begin installation button when you are ready to start the actual installation.
-
On the next screen, while the installation is running, click User creation to create the user ID you will use to log in for normal work.

Select your preferred language.
In this step, you will download and install the latest updates for your system from Red Hat. In the process, you will verify that your system has a current Red Hat subscription and is able to receive updates.
First, start a Terminal window from the Application menu. Then, after using su to change to the root user ID, use subscription-manager to verify that you have access to Red Hat software repositories.
$ su -
# subscription-manager repos --list-enabledIf you don’t see any enabled repositories, your system might not be registered with Red Hat or might not have a valid subscription. See Troubleshooting and FAQ for more information.
Now download and install any available updates by running yum update. If updates are available, yum will list them and ask if it is OK to proceed.
# yum update
In this step you will configure your system to obtain software from the Optional RPMs and RHSCL software repositories. The Optional RPMs repository includes a number of development packages. The RHSCL repository includes the both the RHSCL software collections as well as DTS (the Red Hat Developer Toolset).
# subscription-manager repos --enable rhel-server-rhscl-7-rpms
# subscription-manager repos --enable rhel-7-server-optional-rpmsFirst select a development technology, then set up your development environment and create a simple "Hello, World" application.
[FIXME - Where do the tabs come from?]
-
My system is unable to download updates from Red Hat.
Your system must be registered with Red Hat using
subscription-manager register. You need to have a current Red Hat subscription. -
The RHSCL repository is not available or is not found on my system.
The name of the repository depends on whether you have a server, workstation, or desktop version of Red Hat Enterprise Linux installed.
Some Red Hat Enterprise Linux subscriptions do not include access to RHSCL. For developers, Red Hat Enterprise Linux Developer Suite includes both RHSCL and DTS.
