Lenovo does not offer all of the products, programs and services described in this document in every country. Contact your Lenovo representative for information on what is available in your region.
The License Agreement screen presents the overall licensing terms for Red Hat Enterprise Linux 7. Accept the license agreement to complete initial configuration and exit Initial Setup.
1. Boot from CD/DVD
If your computer can read the CD-ROM drive but fails to boot from it, you may need to make some CMOS changes. The exact procedure will vary from computer to computer.
To change the CMOS settings, reboot your computer and access the BIOS setup utility. Press the key that your system uses to enter setup (the exact button will vary from device to device). In the BIOS, set the first boot option to be your CD/DVD drive.
The graphical installer will then start after a few seconds. It will present you with a Language Selection screen. Select your desired language and continue. The graphical installer will also perform some initial setup tasks, like registering your system with Red Hat. These are explained in the following articles.
2. Select Language
Red Hat Enterprise Linux (RHEL) is a powerful commercial server operating system for physical, cloud and virtual platforms. It comes with large package repositories to support commercial-grade applications.
At this screen, select the language you want to use for your installation process. Also, set the Date & Time and Keyboard settings. When you click on Install, the installer will prompt you to set the root password. Make sure you choose a strong and secure password that will not be easily guessable.
Once you have completed the installation, you must activate the RHEL repositories by using the command “yum repolist”. It’s a good idea to update your system as soon as possible, as updates can contain bug fixes and security enhancements. This will ensure that you get the best out of your RHEL system.
3. Set Root Password
A root password is an administrative password that gives you complete control of the system. Logging in as the root account allows you to install packages, upgrade RPMs, and perform other tasks that require a high level of access privilege. Logging in as the root account also has complete access to all files on the system, so changes made as root can affect the entire system.
To set the root password, select the option and provide a strong password. Then click Done to continue with the installation process.
4. Create a User
Management of user accounts is an imporant system administration task. Each user is assigned a unique numerical identification number called a UID (User ID) and GID (Group ID). In addition to the UID, each user has an associated login shell and home directory.
The next screen presents a single interface for configuring all settings that the installer program needs to install RHEL. Some of these are optional but the installation process will not work without them.
Set the Date & Time, Language System Support and Keyboard Layout as per your requirement. Then hit the Continue button.
When the graphical installer has finished its work, it presents a screen asking you to accept the license agreement and register your system. Once you’ve done that, the program downloads software packages and installs them on the system using yum.
You can also configure the language, region, date and time, keyboard and other configuration options. This is a good opportunity to check that your hardware is compatible with the software you’re installing.
When the installation is complete, the installer prompts you to reboot the system. The system may take a while to boot, depending on the hardware and amount of memory on your computer. Once it’s finished, you can log on and begin using your new RHEL 7 environment. Be sure to update your system as soon as possible to get the most out of it.
