Chapter 3. Installing Satellite Server

When you install Satellite Server from a connected network, you can obtain packages and receive updates directly from the Red Hat Content Delivery Network.

Note

You cannot register Satellite Server to itself.

Use the following procedures to install Satellite Server, perform the initial configuration, and import subscription manifests. For more information on subscription manifests, see Managing Red Hat Subscriptions in Managing content.

Note that the Satellite installation script is based on Puppet, which means that if you run the installation script more than once, it might overwrite any manual configuration changes. ⁠ To avoid this and determine which future changes apply, use the --noop argument when you run the installation script. This argument ensures that no actual changes are made. Potential changes are written to /var/log/foreman-installer/satellite.log.

Files are always backed up and so you can revert any unwanted changes. For example, in the foreman-installer logs, you can see an entry similar to the following about Filebucket: 

/Stage[main]/Dhcp/File[/etc/dhcp/dhcpd.conf]: Filebucketed /etc/dhcp/dhcpd.conf to puppet with sum 622d9820b8e764ab124367c68f5fa3a1

You can restore the previous file as follows: 

# puppet filebucket -l \
restore /etc/dhcp/dhcpd.conf 622d9820b8e764ab124367c68f5fa3a1

Host namePortProtocol

subscription.rhsm.redhat.com

443

HTTPS

cdn.redhat.com

443

HTTPS

cert.console.redhat.com (if using Red Hat Insights)

443

HTTPS

api.access.redhat.com (if using Red Hat Insights)

443

HTTPS

cert-api.access.redhat.com (if using Red Hat Insights)

443

HTTPS

console.redhat.com (if using Red Hat Insights)

443

HTTPS

connect.cloud.redhat.com (if using Red Hat Insights)

443

HTTPS

Satellite Server uses SSL to communicate with the Red Hat CDN securely. An SSL interception proxy interferes with this communication. These hosts must be allowlisted on your HTTP proxy.

For a list of IP addresses used by the Red Hat CDN (cdn.redhat.com), see the Knowledgebase article Public CIDR Lists for Red Hat on the Red Hat Customer Portal.

To configure the Subscription Manager with the HTTP proxy, follow the procedure below.

Procedure

  1. On Satellite Server, complete the following details in the /etc/rhsm/rhsm.conf file: 

    # an http proxy server to use (enter server FQDN)
proxy_hostname = myproxy.example.com

# port for http proxy server
proxy_port = 8080

# user name for authenticating to an http proxy, if needed
proxy_user =

# password for basic http proxy auth, if needed
proxy_password =

3.4. Optional: Using fapolicyd on Satellite Server
Copiar o link

By enabling fapolicyd on your Satellite Server, you can provide an additional layer of security by monitoring and controlling access to files and directories. The fapolicyd daemon uses the RPM database as a repository of trusted binaries and scripts.

You can turn on or off the fapolicyd on your Satellite Server or Capsule Server at any point.

3.4.1. Installing fapolicyd on Satellite Server
Copiar o link

You can install fapolicyd along with Satellite Server or can be installed on an existing Satellite Server. If you are installing fapolicyd along with the new Satellite Server, the installation process will detect the fapolicyd in your Red Hat Enterprise Linux host and deploy the Satellite Server rules automatically.

Prerequisites

  • Ensure your host has access to the BaseOS repositories of Red Hat Enterprise Linux.

Procedure

  1. For a new installation, install fapolicyd: 

    # dnf install fapolicyd
    Copy to Clipboard Toggle word wrap

  2. For an existing installation, install fapolicyd using satellite-maintain packages install: 

    # satellite-maintain packages install fapolicyd
    Copy to Clipboard Toggle word wrap

  3. Start the fapolicyd service: 

    # systemctl enable --now fapolicyd
    Copy to Clipboard Toggle word wrap

Verification

  • Verify that the fapolicyd service is running correctly: 

    # systemctl status fapolicyd
    Copy to Clipboard Toggle word wrap

New Satellite Server or Capsule Server installations

In case of new Satellite Server or Capsule Server installation, follow the standard installation procedures after installing and enabling fapolicyd on your Red Hat Enterprise Linux host.

3.6. Configuring Satellite Server
Copiar o link

Install Satellite Server using the satellite-installer installation script.

This method is performed by running the installation script with one or more command options. The command options override the corresponding default initial configuration options and are recorded in the Satellite answer file. You can run the script as often as needed to configure any necessary options.

3.6.1. Configuring Satellite installation
Copiar o link

This initial configuration procedure creates an organization, location, user name, and password. After the initial configuration, you can create additional organizations and locations if required. The initial configuration also installs PostgreSQL databases on the same server.

The installation process can take tens of minutes to complete. If you are connecting remotely to the system, use a utility such as tmux that allows suspending and reattaching a communication session so that you can check the installation progress in case you become disconnected from the remote system. If you lose connection to the shell where the installation command is running, see the log at /var/log/foreman-installer/satellite.log to determine if the process completed successfully.

Considerations

  • Use the satellite-installer --scenario satellite --help command to display the most commonly used options and any default values.
  • Use the satellite-installer --scenario satellite --full-help command to display advanced options.
  • Specify a meaningful value for the option: --foreman-initial-organization. This can be your company name. An internal label that matches the value is also created and cannot be changed afterwards. If you do not specify a value, an organization called Default Organization with the label Default_Organization is created. You can rename the organization name but not the label.
  • By default, all configuration files configured by the installer are managed. When satellite-installer runs, it overwrites any manual changes to the managed files with the intended values. This means that running the installer on a broken system should restore it to working order, regardless of changes made. For more information on how to apply custom configuration on other services, see Applying Custom Configuration to Satellite.

Procedure

  1. Enter the following command with any additional options that you want to use: 

    # satellite-installer --scenario satellite \
--foreman-initial-organization "My_Organization" \
--foreman-initial-location "My_Location" \
--foreman-initial-admin-username admin_user_name \
--foreman-initial-admin-password admin_password
    Copy to Clipboard Toggle word wrap

    The script displays its progress and writes logs to /var/log/foreman-installer/satellite.log.

3.7. Importing a Red Hat subscription manifest into Satellite Server

  1. In the Satellite web UI, ensure the context is set to the organization you want to use.
  2. In the Satellite web UI, navigate to Content > Subscriptions and click Manage Manifest.
  3. In the Manage Manifest window, click Choose File.
  4. Navigate to the location that contains the Red Hat subscription manifest file, then click Open.

CLI procedure

  1. Copy the Red Hat subscription manifest file from your local machine to Satellite Server: 

    $ scp ~/manifest_file.zip root@satellite.example.com:~/.
    Copy to Clipboard Toggle word wrap

  2. Log in to Satellite Server as the root user and import the Red Hat subscription manifest file: 

    # hammer subscription upload \
--file ~/manifest_file.zip \
--organization "My_Organization"
    Copy to Clipboard Toggle word wrap

You can now enable repositories and import Red Hat content. For more information, see Importing Content in Managing content.
