Configuring Login

If you selected System with GUI as the OS profile to install and configured root passwords without creating users, then at the initial login as root, you're prompted to create an initial user. Setting up the first user can be completed in two ways:

• Create a regular user account, which is the default user setup screen. Enter the required user information as prompted, then click Next to complete the process.
• Create a domain account. For this option, click Enterprise Login on the default screen. A new window opens that prompts for the domain credentials. Use this option if the environment is configured with Active Directory or Identity Management domains for storing all user information. In this manner, the user can use domain credentials to log in to the system's GNOME desktop.

Registering the System

After you install Oracle Linux on a system, you have the option to register the system with the Unbreakable Linux Network (ULN), if you have an account. Registering enables the system to obtain extra packages, updates, and fixes. To register the system, choose one of the following methods:

• Visit https://linux.oracle.com. To obtain Oracle Linux updates from ULN, you must have an Oracle Linux support subscription.
• Use the uln_register shell command, which opens an interactive process.
• Use the Oracle Linux GNOME desktop menu. From the menu, select Activities and then search for ULN Registration. Click the ULN Registration shortcut icon to start the graphical registration wizard.

For more information about installing packages and managing software on the system, see Oracle Linux: Managing Software on Oracle Linux.

If you have an Oracle Linux Premier Support account, you can opt to use Ksplice, to keep systems secure and highly available by automatically updating them with the latest kernel security errata and other critical updates. For more information, see Oracle Linux: Ksplice User's Guide.

Updating Software Packages

After installation is complete, we recommend updating all software packages to the latest available versions on the Oracle yum servers, or from ULN, because software packages are often updated for errata bug and security fixes, and package updates might already be available for packages that are provided on the installation media. To update all packages, run:

sudo dnf update -y

Next Steps

After a basic Oracle Linux installation, you might want to further configure the system for optimization and customization purposes, such as setting system date and time, scheduling tasks, obtaining updates, and so on. For reference, go to the Oracle Linux tutorial page at https://docs.oracle.com/en/operating-systems/oracle-linux/tutorials.html which lists tutorials for different administrative tasks. Tutorials are available for tasks that you run at the command line or through the Cockpit web console.
