Uyuni Server Setup

This section covers SUSE Manager Server setup, using these procedures:

  • Start SUSE Manager setup with YaST

  • Create the main administration account with the SUSE Manager Web UI

  • Name your base organization and add login credentials

  • Synchronize the SUSE Linux Enterprise product channel from SUSE Customer Center

1. Set up SUSE Manager with YaST

This section will guide you through SUSE Manager setup procedures.

Procedure: SUSE Manager Setup

  1. Log in to the SUSE Manager Server and start YaST.

  2. In YaST, navigate to Network Services  Uyuni Setup to begin the setup.

  3. From the introduction screen select Uyuni Setup  Set up Uyuni from scratch and click Next to continue.

  4. Enter an email address to receive status notifications and click Next to continue. SUSE Manager can sometimes send a large volume of notification emails. You can disable email notifications in the Web UI after setup, if you need to.

  5. Enter your certificate information and a password. Passwords must be at at least seven characters in length, and must not contain spaces, single or double quotation marks (' or "), exclamation marks (!), or dollar signs ($). Always store your passwords in a secure location.

    You must have the certificate password to set up the SUSE Manager Proxy.

  6. Click Next to continue.

  7. From the Uyuni Setup  Database Settings screen, enter a database user and password and click Next to continue. Passwords must be at at least seven characters in length, and must not contain spaces, single or double quotation marks (' or "), exclamation marks (!), or dollar signs ($). Always store your passwords in a secure location.

  8. Click Next to continue.

  9. Click Yes to run setup when prompted.

  10. When setup is complete, click Next to continue. You will see the address of the SUSE Manager Web UI.

  11. Click Finish to complete SUSE Manager setup.

2. Create the Main Administration Account

This section covers how to create your organization’s main administration account for SUSE Manager.

The main administration account has the highest authority within SUSE Manager. Ensure you keep access information for this account secure.

We recommend that you create lower level administration accounts for organizations and groups. Do not share the main administration access details.

Newer browser versions can block web access to the SUSE Manager Server FQDN because of HSTS.

Installing the CA certificate from the pub directory via HTTP and importing it to the browser will allow access to the server.

  1. On the server, go to http://<server>.example.com/pub/RHN-ORG-TRUSTED-SSL-CERT.

  2. Import the certificate file. In the browser settings (for Firefox), open Privacy & Security  Certificates  View Certificates, and import the file.
Procedure: Setting Up the Main Administration Account

  1. In your web browser, enter the address for the SUSE Manager Web UI. This address was provided after you completed setup. For more information, see Set up SUSE Manager with YaST.

  2. Log in to the Web UI, navigate to the Create Organization  Organization Name field, and enter your organization name.

  3. In the Create Organization  Desired Login and Create Organization  Desired Password fields, enter your username and password.

  4. Fill in the Account Information fields including an email for system notifications.

  5. Click Create Organization to finish creating your administration account.

When you have completed the SUSE Manager Web UI setup, you are taken to the Home  Overview page.

3. Optional: Synchronizing Products from SUSE Customer Center

SUSE Customer Center (SCC) maintains a collection of repositories which contain packages, software and updates for all supported enterprise client systems. These repositories are organized into channels each of which provide software specific to a distribution, release, and architecture. After synchronizing with SCC, clients can receive updates, be organized into groups, and assigned to specific product software channels.

This section covers synchronizing with SCC from the Web UI and adding your first client channel.

For Uyuni, synchronizing products from SUSE Customer Center is optional.

Before you can synchronize software repositories with SCC, you will need to enter organization credentials in SUSE Manager. The organization credentials give you access to the SUSE product downloads. You will find your organization credentials in https://scc.suse.com/organizations.

Enter your organization credentials in the SUSE Manager Web UI:

Procedure: Entering Organization Credentials

  1. In the SUSE Manager Web UI, navigate to Main Menu  Admin  Setup Wizard.

  2. In the Setup Wizard page, navigate to the Organization Credentials tab.

  3. Click Add a new credential.

  4. Enter a username and password, and click Save.

A check mark icon is shown when the credentials are confirmed. When you have successfully entered the new credentials, you can synchronize with SUSE Customer Center.

Procedure: Synchronizing with SUSE Customer Center

  1. In the SUSE Manager Web UI, navigate to Admin  Setup Wizard.

  2. From the Setup Wizard page select the SUSE Products tab. Wait a moment for the products list to populate. If you previously registered with SUSE Customer Center a list of products will populate the table. This table lists architecture, channels, and status information. For more information, see Wizard.

  3. If your SUSE Linux Enterprise client is based on x86_64 architecture scroll down the page and select the check box for this channel now.

    • Add channels to SUSE Manager by selecting the check box to the left of each channel. Click the arrow symbol to the left of the description to unfold a product and list available modules.

    • Click Add Products to start product synchronization.

After adding the channel, SUSE Manager will schedule the channel to be synchronized. This can take a long time as SUSE Manager will copy channel software sources from the SUSE repositories located at SUSE Customer Center to local /var/spacewalk/ directory of your server.

In some environments, transparent huge pages provided by the kernel can slow down PostgreSQL workloads significantly.

To disable transparent huge pages, set the transparent_hugepage kernel parameter to never. You will also need to open the /etc/default/grub file and add or edit the line GRUB_CMDLINE_LINUX_DEFAULT. For example:

GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/sda1 splash=silent quiet showopts elevator=none transparent_hugepage=never"

To write the new configuration run grub2-mkconfig -o /boot/grub2/grub.cfg.

Monitor the channel synchronization process in real-time by viewing channel log files located in the directory /var/log/rhn/reposync:

tail -f /var/log/rhn/reposync/<CHANNEL_NAME>.log

When the channel synchronization process is complete, you can continue with client registration. For more instructions, see Client Registration.
