4.2 Uyuni Setup #
Warning: Third Party Software
Uyuni is an extension of SUSE Linux Enterprise Server and compatible with the software shipped with SUSE Linux Enterprise Server.
Uyuni is a complex system, and therefore installing third party is not allowed. Installing monitoring software provided by a third party vendor is allowed only if you do not exchange basic libraries such as SSL, cryptographic software, and similar tools. In case of emergency, SUSE reserves the right to ask to remove any third party software (and associated configuration changes) and then to reproduce the problem on a clean system.
This section will guide you through Uyuni setup procedures.
Procedure: Uyuni Setup #
Login to the Uyuni server desktop and perform one of the following actions to begin setup:
Select › › › .
Open a terminal as root and type
yast2 susemanager_setupto begin setup.
From the introduction screen select › . Then click to continue.
Enter the email address that should receive status notifications about Uyuni. The number of emails sent from Uyuni can be extensive, therefore notifications via email may be disabled from the Web UI after setup. Then click to continue.
Enter your certificate information and a password. The password should be stored in a secure location.
Important: Certificate Password
Without this password it will not be possible to set up a Uyuni Proxy Server.
Click to continue.
From the › screen, enter a database user and password. This password should be stored in a secure location. Then click to continue.
Enter your SUSE Customer Center
Organization Credentials. Open https://scc.suse.com/login to register or access to your organization credentials.
Note:
If you are using SUSE Enterprise products, Uyuni requires that you connect to SUSE Customer Center for software, updates and patches. You will not be able to synchronize or provide Enterprise channels to your clients without this information.
However if you would like to work with open source software channels and repositories then click the button to continue. You can setup your SUSE Customer Center credentials or configure inter-server sync at a later time.
Click to continue.
Click to run setup when prompted.
Once setup has completed, click to continue. You will see the address of the Uyuni Web UI.
Click to complete Uyuni setup.
In the next section you will create the administrator’s account and synchronize with SUSE Customer Center.
4.2.1 Creating the Main Administration Account #
This section will walk you through creating your organizations main administration account for Uyuni.
Warning: Admin and User Accounts
The main administration account is the highest authority account within Uyuni and therefore account access information should be stored in a secure location.
For security it is recommended that the main administrator creates low level admin accounts designated for administration of organizations and individual groups.
Procedure: Setup the Main Administration Account #
In the browser, enter the address provided after completing setup and open the Uyuni Web UI.
Add your organization name to the › field.
Add your username and password to the › and › fields.
Fill in the Account Information fields including an email for system notifications.
Select to finish creating your administration account.
You should now be presented with the Uyuni Front Page. In the next section you will prepare the server for connecting the first client.
4.2.2 Syncing 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 may receive updates, and 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.
Procedure: Synchronizing with SUSE Customer Center #
From the Uyuni Web UI start page select › .
From the › › page select the 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: ???TITLE???
Since Your SUSE Linux Enterprise client is based on
x86_64architecture scroll down the page and select the check box for this channel now.Add channels to Uyuni 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.
Start product synchronization by clicking the button.
After adding the channel Uyuni will schedule the channel to be copied.
This can take a long time as Uyuni will copy channel software sources from the SUSE repositories located at SUSE Customer Center to local /var/spacewalk/ directory of your server.
Tip: PostgreSQL and Transparant Huge Pages
In some environments, Transparent Huge Pages provided by the kernel may slow down PostgreSQL workloads significantly.
To disable Transparant Huge Pages set the transparent_hugepage kernel parameter to never.
This has to be changed in /etc/default/grub and added to the line GRUB_CMDLINE_LINUX_DEFAULT, for example:
GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/sda1 splash=silent quiet showopts elevator=noop transparent_hugepage=never"
To write the new configuration run grub2-mkconfig -o /boot/grub2/grub.cfg.
To update the grub2 during boot run grub2-install /dev/sda.
Monitor channel synchronization process in real-time by viewing channel log files located in the directory /var/log/rhn/reposync:
tailf /var/log/rhn/reposync/<CHANNEL_NAME>.log
After the channel sync process has completed proceed to: Chapter 5, Registering Clients
