On this screen, you can choose between locally available installation media, such as a DVD or an ISO file, or a network location. Auto-detected installation media If you started the installation using the full installation DVD or USB drive, the installation program will detect it and display basic information under this option. Click the Verify button to ensure that the media is suitable for installation. This option will appear if the installation program detected a partitioned hard drive with mountable file systems.

For NFS installation it is not necessary to mount the iso image. It is sufficient to make the iso image itself available via NFS. You can do this by moving the iso image or images to the NFS exported directory:. Since rpc. Replace file-systems with additional file systems to be exported. This option is often used to test an exported file system before adding it permanently to the list of file systems to be exported.

Unexports all shared directories. To re-enable NFS sharing, use exportfs -r. Verbose operation, where the file systems being exported or unexported are displayed in greater detail when the exportfs command is executed. If no options are passed to the exportfs command, it displays a list of currently exported file systems. For more information about the exportfs command, see man exportfs. Using exportfs with NFSv4.

This was not the case in previous versions. NFS requires rpcbind , which dynamically assigns ports for RPC services and can cause issues for configuring firewall rules.

Commonly, NFS fails to start if you specify a port number that is already in use. To allow NFSv4. This process is not needed for NFSv4. Discovering NFS exports. On any server that supports NFSv3, use the showmount command:.

On any server that supports NFSv4, mount the root directory and look around. If you apply a security policy to the system, it is installed using restrictions and recommendations defined in the profile that you selected. The openscap-scanner package is added to your package selection, providing a preinstalled tool for compliance and vulnerability scanning.

After the installation finishes, the system is automatically scanned to verify compliance. Profile changes that you must apply before installation appear in the bottom pane.

The default profiles do not require changes before installation. However, loading a custom profile can require pre-installation tasks. Click Change content to use a custom profile. A separate window opens allowing you to enter a URL for valid security content. A network connection must be active before you can load a custom profile.

The installation program detects the content type automatically. This section contains information about configuring your installation source and software selection settings, and activating a repository.

Complete the steps in this procedure to configure an installation source from either auto-detected installation media, Red Hat CDN, or the network. When the Installation Summary window first opens, the installation program attempts to configure an installation source based on the type of media that was used to boot the system. From the Installation Summary window, click Installation Source. The Installation Source window opens. Review the Additional repositories section and note that the AppStream checkbox is selected by default.

Optional: Select the On the network option to download and install packages from a network location instead of local media. Type the server address without the protocol into the address field. This field accepts options listed in the nfs 5 man page. When selecting an NFS installation source, you must specify the address with a colon : character separating the host name from the path. For example:. The following steps are optional and are only required if you use a proxy for network access.

All environments and additional software packages are available for selection when you finish configuring the sources. To activate or deactivate a repository, click the check box in the Enabled column for each entry in the list. You can name and configure your additional repository in the same way as the primary repository on the network.

Use the Software Selection window to select the software packages that you require. The packages are organized by Base Environment and Additional Software. Use a predefined environment and additional software to customize your system. However, in a standard installation, you cannot select individual packages to install. The XML file contains details of the packages installed as part of a base environment. If you are unsure about which packages to install, Red Hat recommends that you select the Minimal Install base environment.

Minimal install installs a basic version of Red Hat Enterprise Linux with only a minimal amount of additional software. After the system finishes installing and you log in for the first time, you can use the YUM package manager to install additional software.

For more information about YUM package manager, see the Configuring basic system settings document. From the Base Environment pane, select a base environment. You can select only one base environment. The Server with GUI base environment is the default base environment and it launches the Initial Setup application after the installation completes and you restart the system. You can install Red Hat Enterprise Linux on a large variety of storage devices.

You can configure basic, locally accessible, storage devices in the Installation Destination window. Basic storage devices directly connected to the local system, such as hard disk drives and solid-state drives, are displayed in the Local Standard Disks section of the window.

These storage devices are available during the installation, but are not immediately accessible after you finish installing and reboot. The storage device selection window lists all storage devices that the installation program can access. Depending on your system and available hardware, some tabs might not be displayed. The devices are grouped under the following tabs:.

Storage devices accessible through more than one path, such as through multiple SCSI controllers or Fiber Channel ports on the same system. The installation program only detects multipath storage devices with serial numbers that are 16 or 32 characters long.

Select the check box to enable the device that you require during the installation process. Later in the installation process you can choose to install Red Hat Enterprise Linux on any of the selected devices, and you can choose to mount any of the other selected devices as part of the installed system automatically. Any storage devices that you do not select are hidden from the installation program entirely. To chain load the boot loader from a different boot loader, select all the devices present.

You cannot change the name of the iSCSI initiator after you attempt discovery for the first time. To change the iSCSI initiator name, you must restart the installation. Complete the following steps to discover and start an iSCSI session. A valid IQN entry contains the following information:. A colon followed by a string that uniquely identifies this particular iSCSI initiator within your domain or subdomain.

For example, :diskarrays-sn-a A complete IQN is as follows: iqn. The installation program prepopulates the iSCSI Initiator Name field with a name in this format to help you with the structure. For more information about IQNs, see 3. The following options are available:. The installation program attempts to discover an iSCSI target based on the information provided. Select the check boxes for the node that you want to use for installation. The Node login authentication type menu contains the same options as the Discovery Authentication Type menu.

However, if you need credentials for discovery authentication, use the same credentials to log in to a discovered node. Complete the following steps to configure DASD storage devices. You can enter FCP devices either in the graphical installation, or as a unique parameter entry in the parameter or CMS configuration file.

The values that you enter must be unique to each site that you configure. The newly-added devices are displayed in the System z Devices tab of the Installation Destination window. Enter the sector size that you require and click Start Reconfiguration. Click Done to return to the Installation Destination window. Additionally, if the device meets the requirements for booting, you can set the device as a boot device. You can use manual partitioning to configure your disk partitions and mount points and define the file system that Red Hat Enterprise Linux is installed on.

Before installation, you should consider whether you want to use partitioned or unpartitioned disk devices. You can also create additional partitions and volumes as you require.

To prevent data loss it is recommended that you back up your data before proceeding. If you are upgrading or creating a dual-boot system, you should back up any data you want to keep on your storage devices.

If you selected to encrypt the storage, a dialog box for entering a disk encryption passphrase opens. Type in the LUKS passphrase:. Enter the passphrase in the two text fields. To switch keyboard layout, use the keyboard icon. In the dialog box for entering the passphrase, you cannot change the keyboard layout. Select the English keyboard layout to enter the passphrase in the installation program.

Detected mount points are listed in the left-hand pane. The mount points are organized by detected operating system installations.

As a result, some file systems may be displayed multiple times if a partition is shared among several installations. Select the mount points in the left pane; the options that can be customized are displayed in the right pane. If your system contains existing file systems, ensure that enough space is available for the installation. To remove any partitions, select them in the list and click the - button.

The dialog has a check box that you can use to remove all other partitions used by the system to which the deleted partition belongs. If there are no existing partitions and you want to create the recommended set of partitions as a starting point, select your preferred partitioning scheme from the left pane default for Red Hat Enterprise Linux is LVM and click the Click here to create them automatically link.

These are the recommended file systems for a typical installation, but you can add additional file systems and mount points. Continue with adding mount points , configuring the individual mount points , and configuring the underlying partitions or volumes. Complete the following steps to add multiple mount point file systems.

Enter the size of the file system in to the Desired Capacity field; for example, 2GiB. If you do not specify a value in the Desired Capacity field, or if you specify a size bigger than available space, then all remaining free space is used. This procedure describes how to set the partitioning scheme for each mount point that was created manually.

In the lower left-hand side of the Manual Partitioning window, click the storage device selected link to open the Selected Disks dialog and review disk information. Click the Rescan button circular arrow button to refresh all local disks and partitions; this is only required after performing advanced partition configuration outside the installation program.

Clicking the Rescan Disks button resets all configuration changes made in the installation program. You can customize a partition or volume if you want to set specific settings. In some situations, such as when these directories are placed on an iSCSI drive or an FCoE location, the system is unable to boot, or hangs with a Device is busy error when powering off or rebooting.

RAID is available only if two or more disks are selected for partitioning. Select the appropriate file system type for this partition or volume from the File system drop-down menu. Type a name in the Name field. Note that standard partitions are named automatically when they are created and you cannot edit the names of standard partitions. Click Update Settings to apply your changes and if required, select another partition to customize.

Changes are not applied until you click Begin Installation from the Installation Summary window. Click Done when you have created and customized all file systems and mount points. If you choose to encrypt a file system, you are prompted to create a passphrase.

A Summary of Changes dialog box opens, displaying a summary of all storage actions for the installation program. RAID devices are constructed from multiple storage devices that are arranged to provide increased performance and, in some configurations, greater fault tolerance. A RAID device is created in one step and disks are added or removed as necessary.

You can configure one RAID partition for each physical disk in your system, so the number of disks available to the installation program determines the levels of RAID device available. For example, if your system has two hard drives, you cannot create a RAID 10 device, as it requires a minimum of three separate disks.

You do not have to configure software RAID manually. A message is displayed at the bottom of the window if the specified RAID level requires more disks. Partitions on physical storage are represented as physical volumes that you can group together into volume groups. You can divide each volume group into multiple logical volumes, each of which is analogous to a standard disk partition.

Therefore, LVM logical volumes function as partitions that can span multiple physical disks. During text-mode installation, LVM configuration is not available. You can run vgcreate and lvm commands in this shell. The Volume Group drop-down menu is displayed with the newly-created volume group name.

The size is always set to the default value of 4 MiB. Follow the steps in this procedure to configure a newly-created LVM logical volume. Click Modify to configure the newly-created volume group. The Configure Volume Group dialog box opens. From the Size policy drop-down menu, select the size policy for the volume group. You must configure a root password to finish the installation process and to log in to the administrator also known as superuser or root account that is used for system administration tasks.

These tasks include installing and updating software packages and changing system-wide configuration such as network and firewall settings, storage options, and adding or modifying users, groups and file permissions.

Use one or both of the following ways to gain root privileges to the installed system:. The root account has complete control over the system. If unauthorized personnel gain access to the account, they can access or delete users' personal files. Type your password in the Root Password field. The requirements and recommendations for creating a strong root password are:. Click Done to confirm your root password and return to the Installation Summary window.

If you proceeded with a weak password, you must click Done twice. It is recommended that you create a user account to finish the installation. If you do not create a user account, you must log in to the system as root directly, which is not recommended.

Type the username in to the User name field, for example: jsmith. The User name is used to log in from a command line; if you install a graphical environment, then your graphical login manager uses the Full name. Select the Make this user administrator check box if the user requires administrative rights the installation program adds the user to the wheel group. An administrator user can use the sudo command to perform tasks that are only available to root using the user password, instead of the root password.

This may be more convenient, but it can also cause a security risk. Select the Require a password to use this account check box. If you give administrator privileges to a user, verify that the account is password protected. Never give a user administrator privileges without assigning a password to the account. This procedure describes how to edit the default settings for the user account in the Advanced User Configuration dialog box.

In the User and Groups IDs section you can:. The default value is GIDs are reserved by the system so they can not be assigned to a user group. Specify additional groups as a comma-separated list in the Group Membership field.

Groups that do not already exist are created; you can specify custom GIDs for additional groups in parentheses. This section describes how to complete the following post-installation tasks:.

Depending on your requirements, there are several methods to register your system. Most of these methods are completed as part of post-installation tasks. This section contains information about how to complete initial setup on a Red Hat Enterprise Linux 8 system. The information displayed in the Initial Setup window might vary depending on what was configured during installation. At a minimum, the Licensing and Subscription Manager options are displayed.

From the Initial Setup window, select Licensing Information. Review the license agreement and select the I accept the license agreement checkbox. You must accept the license agreement.

Exiting Initial Setup without completing this step causes a system restart. When the restart process is complete, you are prompted to accept the license agreement again. Click Done to apply the settings and return to the Initial Setup window.

If you did not configure network settings, you cannot register your system immediately. In this case, click Finish Configuration. Red Hat Enterprise Linux 8 starts and you can login, activate access to the network, and register your system. See Subscription manager post installation for more information. If you configured network settings, as described in Network hostname , you can register your system immediately, as shown in the following steps:.

From the Initial Setup window, select Subscription Manager. This section contains information about how to register your Red Hat Enterprise Linux 8 subscription using the command line. When auto-attaching a system, the subscription service checks if the system is physical or virtual, as well as how many sockets are on the system.

A physical system usually consumes two entitlements, a virtual system usually consumes one. One entitlement is consumed per two sockets on a system. When the system is successfully registered, an output similar to the following is displayed:. Available roles depend on the subscriptions that have been purchased by the organization and the architecture of the Red Hat Enterprise Linux 8 system.

Attach the system to an entitlement that matches the host system architecture:. When a subscription is successfully attached, an output similar to the following is displayed:. An alternative method for registering your Red Hat Enterprise Linux 8 system is by logging in to the system as a root user and using the Subscription Manager graphical user interface.

This section contains information about how to register your Red Hat Enterprise Linux 8 system using the Subscription Manager User Interface to receive updates and access package repositories.

Enter your administrator password in the Authentication Required dialog box. The Register button in the Subscriptions window changes to Unregister and installed products display a green X. You can troubleshoot an unsuccessful registration from a terminal window using the subscription-manager status command.

Registration Assistant is designed to help you choose the most suitable registration option for your Red Hat Enterprise Linux environment. You can use System Purpose to record the intended use of a Red Hat Enterprise Linux 8 system, and ensure that the entitlement server auto-attaches the most appropriate subscription to your system. If System Purpose was not configured during the installation process, you can use the syspurpose command-line tool after installation to set the required attributes.

If your system is registered but has subscriptions that do not satisfy the required purpose, you can run the subscription-manager remove --all command to remove attached subscriptions. You can then use the syspurpose command-line tool to set the required purpose attributes, and run subscription-manager attach --auto to entitle the system with the updated attributes. Complete the steps in this procedure to configure System Purpose after installation using the syspurpose command-line tool.

The selected values are used by the entitlement server to attach the most suitable subscription to your system. From a terminal window, run the following command to set the intended role of the system:. Run the following command to show the current system purpose properties:. Optional: Run the following command to access the syspurpose man page:. Complete the following security-related steps immediately after you install Red Hat Enterprise Linux.

Even though the firewall service, firewalld , is automatically enabled with the installation of Red Hat Enterprise Linux, there are scenarios where it might be explicitly disabled, for example in a Kickstart configuration. In that scenario, it is recommended that you re-enable the firewall. To start firewalld , run the following commands as root:. To enhance security, disable services that you do not need.

For example, if your system has no printers installed, disable the cups service using the following command:. Using this deployment method, you can apply specific rules that cannot be applied later using remediation scripts, for example, a rule for password strength and partitioning.

Therefore, do not select Server with GUI when installing systems compliant with one of the following profiles:. Packages xorg-xserver-Xorg , xorg-xserver-common , xorg-xserver-utils , and xorg-xserver-Xwayland are part of the Server with GUI package set, but the policy requires their removal. The nfs-utils package is part of the Server with GUI package set, but the policy requires its removal.

BZ Use this procedure to deploy a RHEL system that is aligned with a specific baseline. For additional details, see Profiles not compatible with a GUI server. The graphical installation program automatically creates a corresponding Kickstart file after a successful installation. To check the current status of the system after installation is complete, reboot the system and start a new scan:. Use this procedure to deploy RHEL systems that are aligned with a specific baseline.

Update the partitioning scheme to fit your configuration requirements.
