For more information, see the documentation that came with your system. Use the arrow keys on your keyboard to select the boot option that you require, and press Enter to select the boot option.
The installation program automatically begins if no action is performed in the boot window within 60 seconds. When installing Red Hat Enterprise Linux on a large number of systems simultaneously, the best approach is to boot from a PXE server and install from a source in a shared network location. To boot the installation process from a network using PXE, you must use a physical network connection, for example, Ethernet.
You cannot boot the installation process with a wireless connection. Depending on your hardware, some network setup and diagnostic information can be displayed before your system connects to a PXE server. When connected, a menu is displayed according to the PXE server configuration. In some instances, boot options are not displayed. If this occurs, press the Enter key on your keyboard or wait until the boot window opens.
The Red Hat Enterprise Linux boot window opens and displays information about a variety of available boot options. When performing a GUI installation using the DVD ISO image file, a race condition in the installer can sometimes prevent the installation from proceeding until you register the system using the Connect to Red Hat feature. In the Create User window, perform the following, and then click Done. Remove any installation media if it is not ejected automatically upon reboot.
If your system was installed on a workstation with the X Window System, applications to configure your system are launched. These applications guide you through initial configuration and you can set your system time and date, register your system with Red Hat, and more. If the X Window System is not installed, a login: prompt is displayed.
The content can be consumed directly, such as using a system registered to Red Hat Subscription Management. The CDN is protected by x. When a system is registered to Red Hat Subscription Management, the attached subscriptions govern which subset of the CDN the system can access. In the Connect to Red Hat window, perform the following steps:. Select the Authentication method, and provide the details based on the method you select.
You can enter more than one activation key, separated by a comma, as long as the activation keys are registered to your subscription. With System Purpose you can 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.
The Connect to Red Hat Insights check box is enabled by default. Clear the check box if you do not want to connect to Red Hat Insights. Red Hat Insights is a Software-as-a-Service SaaS offering that provides continuous, in-depth analysis of registered Red Hat-based systems to proactively identify threats to security, performance and stability across physical, virtual and cloud environments, and container deployments.
Optionally, expand Options , and select the network communication type. To change the Custom base URL after registration, you must unregister, provide the new details, and then re-register. Click Register. When the system is successfully registered and subscriptions are attached, the Connect to Red Hat window displays the attached subscription details. Depending on the amount of subscriptions, the registration and attachment process might take up to a minute to complete.
A Registered message is displayed under Connect to Red Hat. In the Root Password window, type the password that you want to set for the root account, and then click Done. A root password is required to finish the installation process and to log in to the system administrator user account. For more details about the requirements and recommendations for creating a password, see Configuring a root password.
Select the Make this user administrator and the Require a password to use this account check boxes. The installation program adds the user to the wheel group, and creates a password protected user account with default settings. It is recommended to create a password protected administrative user account.
For more information about editing the default settings for a user account, see Creating a user account. The installation source repository used after system registration is dependent on how the system was booted. You can only verify your registration from the CDN if you have not clicked the Begin Installation button from the Installation Summary window. Once the Begin Installation button is clicked, you cannot return to the Installation Summary window to verify your registration.
When unregistering, the installation program switches to the first available repository, in the following order:. The Connect to Red Hat window opens and displays a registration summary:. After unregistering, it is possible to register your system again. Click Connect to Red Hat. The previously entered details are populated. Edit the original details, or update the fields based on the account, purpose, and connection. Click Register to complete.
When installing Red Hat Enterprise Linux, you can customize location, software, and system settings and parameters, using the Installation Summary window. The Installation Summary window contains the following categories:. Requires attention before installation. The installation program is configuring a category and you must wait for it to finish before accessing the window.
A warning message is displayed at the bottom of the Installation Summary window and the Begin Installation button is disabled until you configure all of the required categories. There may be some variance between the online help and the content that is published on the Customer Portal.
For the latest updates, see the installation content on the Customer Portal. The installation program uses the language that you selected during installation. Alternatively, type your preferred language into the Search field. A language is pre-selected by default. If network access is configured, that is, if you booted from a network server instead of local media, the pre-selected language is determined by the automatic location detection feature of the GeoIP module.
If you used the inst. If you are installing a pre-release version of Red Hat Enterprise Linux, a warning message is displayed about the pre-release status of the installation media. This section contains information about configuring your keyboard, language support, and time and date settings. If you use a layout that cannot accept Latin characters, such as Russian , add the English United States layout and configure a keyboard combination to switch between the two layouts. If you select a layout that does not have Latin characters, you might be unable to enter a valid root password and user credentials later in the installation process.
This might prevent you from completing the installation. To change any of the settings, complete the following steps, otherwise proceed to Configuring software settings. To configure key combinations for switching, select one or more key combinations and click OK to confirm your selection. When you select a layout, click the Keyboard button to open a new dialog box that displays a visual representation of the selected layout. Red Hat can not add cities or regions to this database.
You can find more information at the IANA official website. From the Region drop-down menu, select a region. Select Etc as your region to configure a time zone relative to Greenwich Mean Time GMT without setting your location to a specific region. Enabling the Network Time switch keeps your system time correct as long as the system can access the internet. By default, one NTP pool is configured; you can add a new option, or disable or remove the default options by clicking the gear wheel button next to the Network Time switch.
Click Done to apply the changes and return to Graphical installations. If you disable network time synchronization, the controls at the bottom of the window become active, allowing you to set the time and date manually. Use the Installation Destination window to configure the storage options, for example, the disks that you want to use as the installation target for your Red Hat Enterprise Linux installation. You must select at least one disk. Back up your data if you plan to use a disk that already contains data.
For example, if you want to shrink an existing Microsoft Windows partition and install Red Hat Enterprise Linux as a second system, or if you are upgrading a previous release of Red Hat Enterprise Linux. Manipulating partitions always carries a risk. For example, if the process is interrupted or fails for any reason data on the disk can be lost.
The Installation Summary window is open. From the Installation Summary window, click Installation Destination. The Installation Destination window opens. From the Local Standard Disks section, select the storage device that you require; a white check mark indicates your selection. Disks without a white check mark are not used during the installation process; they are ignored if you choose automatic partitioning, and they are not available in manual partitioning.
Any storage devices connected after the installation program has started are not detected. If you use a removable drive to install Red Hat Enterprise Linux, your system is unusable if you remove the device. Optional: Click the Refresh link in the lower right-hand side of the window if you want to configure additional local storage devices to connect new hard drives.
The Rescan Disks dialog box opens. All storage changes that you make during the installation are lost when you click Rescan Disks. The Storage Device Selection window opens and lists all storage devices that the installation program has access to.
Optional: Under Storage Configuration , select the Automatic radio button. Automatic partitioning is the recommended method of partitioning your storage. You can also configure custom partitioning, for more details see Configuring manual partitioning. Encrypting your hard drive is recommended.
Click Done. The Disk Encryption Passphrase dialog box opens. Click Save Passphrase to complete disk encryption. If you lose the LUKS passphrase, any encrypted partitions and their data is completely inaccessible. There is no way to recover a lost passphrase. However, if you perform a Kickstart installation, you can save encryption passphrases and create backup encryption passphrases during the installation.
Optional: Click the Full disk summary and bootloader link in the lower left-hand side of the window to select which storage device contains the boot loader. For more information, see Boot loader installation. In most cases it is sufficient to leave the boot loader in the default location. Some configurations, for example, systems that require chain loading from another boot loader require the boot drive to be specified manually.
If you selected automatic partitioning and I would like to make additional space available , or if there is not enough free space on your selected hard drives to install Red Hat Enterprise Linux, the Reclaim Disk Space dialog box opens when you click Done , and lists all configured disk devices and all partitions on those devices.
The dialog box displays information about how much space the system needs for a minimal installation and how much space you have reclaimed. If you delete a partition, all data on that partition is lost. If you want to preserve your data, use the Shrink option, not the Delete option. To reclaim space, select a disk or partition, and click either the Delete button to delete that partition, or all partitions on a selected disk, or click Shrink to use free space on a partition while preserving the existing data.
Alternatively, you can click Delete all , this deletes all existing partitions on all disks and makes this space available to Red Hat Enterprise Linux. Existing data on all disks is lost. No disk changes are made until you click Begin Installation on the Installation Summary window. The Reclaim Space dialog only marks partitions for resizing or deletion; no action is performed.
For bit IBM Z, the zipl boot loader is used. The boot loader is the first program that runs when the system starts and is responsible for loading and transferring control to an operating system. GRUB2 can boot any compatible operating system including Microsoft Windows and can also use chain loading to transfer control to other boot loaders for unsupported operating systems. Installing GRUB2 may overwrite your existing boot loader.
If an operating system is already installed, the Red Hat Enterprise Linux installation program attempts to automatically detect and configure the boot loader to start the other operating system. If the boot loader is not detected, you can manually configure any additional operating systems after you finish the installation.
If you are installing a Red Hat Enterprise Linux system with more than one disk, you might want to manually specify the disk where you want to install the boot loader. From the Installation Destination window, click the Full disk summary and bootloader link. The Selected Disks dialog box opens. The boot loader is installed on the device of your choice, or on a UEFI system; the EFI system partition is created on the target device during guided partitioning.
If you choose not to install a boot loader, you cannot boot the system directly and you must use another boot method, such as a standalone commercial boot loader application. Use this option only if you have another way to boot your system. If you use automatic partitioning, the installation program creates the partition. Kdump is a kernel crash-dumping mechanism. In the event of a system crash, Kdump captures the contents of the system memory at the moment of failure.
This captured memory can be analyzed to find the cause of the crash. This reserved memory is not accessible to the main kernel. Select either the Automatic or Manual memory reservation setting. The amount of memory that you reserve is determined by your system architecture AMD64 and Intel 64 have different requirements than IBM Power as well as the total amount of system memory. In most cases, automatic reservation is satisfactory.
Use the Network and Host name window to configure network interfaces. Options that you select here are available both during the installation for tasks such as downloading packages from a remote location, and on the installed system. Follow the steps in this procedure to configure your network and host name. From the list in the left-hand pane, select an interface. The details are displayed in the right-hand pane.
The installation program automatically detects locally accessible interfaces, and you cannot add or remove them manually. Type a host name for your system in the Host Name field. This procedure describes how to add a virtual network interface. Select the interface type and click Add.
An editing interface dialog box opens, allowing you to edit any available settings for your chosen interface type. For more information see Editing network interface. If you need to change the settings of a virtual interface, select the interface and click Configure. This section contains information about the most important settings for a typical wired connection used during installation. Configuration of other types of networks is broadly similar, although the specific configuration parameters might be different.
On bit IBM Z, you cannot add a new connection as the network subchannels need to be grouped and set online beforehand, and this is currently done only in the booting phase. To configure a network connection manually, select the interface from the Network and Host name window and click Configure. The options present depend on the connection type - the available options are slightly different depending on whether the connection type is a physical interface wired or wireless network interface controller or a virtual interface Bond, Bridge, Team, or Vlan that was previously configured in Adding a virtual interface.
The following sections contain information about the three most common and useful options in the editing dialog:. Follow the steps in this procedure to enable or disable an interface connection. Select the Connect automatically with priority check box to enable connection by default. Keep the default priority setting at 0. By default, both IPv4 and IPv6 are set to automatic configuration depending on current network settings. This means that addresses such as the local IP address, DNS address, and other settings are detected automatically when the interface connects to a network.
In many cases, this is sufficient, but you can also provide static configuration in the IPv4 Settings and IPv6 Settings tabs. Complete the following steps to configure IPv4 or IPv6 settings:. To set static network configuration, navigate to one of the IPv Settings tabs and from the Method drop-down menu, select a method other than Automatic , for example, Manual. The Addresses pane is enabled. Select the Require IPv X addressing for this connection to complete check box. If this option remains disabled for both IPv4 and IPv6, the interface is able to connect if configuration succeeds on either IP protocol.
Select the Use this connection only for resources on its network check box to prevent the connection from becoming the default route. This option can be selected even if you did not configure any static routes. This route is used only to access certain resources, such as intranet pages that require a local or VPN connection. Another default route is used for publicly available resources. Unlike the additional routes configured, this setting is transferred to the installed system.
This option is useful only when you configure more than one interface. You 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. To record the intended purpose of your system, you can configure the following components of System Purpose. The selected values are used by the entitlement server upon registration to attach the most suitable subscription for your system.
Service Level Agreement. Optional: Click Activation Key. Select the Set System Purpose check box. System Purpose enables the entitlement server to determine and automatically attach the most appropriate subscription to satisfy the intended use of Red Hat Enterprise Linux 8 system. Optional: Expand Options. Click Register to register the system. Click Done to return to the Installation Summary window. This section contains information about applying Red Hat Enterprise Linux 8 security policy during installation and how to configure it for use on your system before the first boot.
The packages are available in the AppStream repository. However, by default, the installation and post-installation process does not enforce any policies and therefore does not involve any checks unless specifically configured.
Applying a security policy is not a mandatory feature of the installation program. 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 and scap-security-guide packages are added to your package selection, providing a preinstalled tool for compliance and vulnerability scanning.
There might be conflicting package selections, as well as separate partitions defined. Only after all the requirements are met, you can start the installation. By default, the installer uses the content of the scap-security-guide package bundled in the installation image.
Profile changes that you must apply before installation appear in the bottom pane. 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:.
