2장. Installing Capsule Server


Before you install Capsule Server, you must ensure that your environment meets the requirements for installation. For more information, see Preparing your Environment for Installation.

2.1. Registering to Satellite Server

Use this procedure to register the base operating system on which you want to install Capsule Server to Satellite Server.

Red Hat subscription manifest prerequisites

  • On Satellite Server, a manifest must be installed and it must contain the appropriate repositories for the organization you want Capsule to belong to.
  • The manifest must contain repositories for the base operating system on which you want to install Capsule, as well as any clients that you want to connect to Capsule.
  • The repositories must be synchronized.

For more information on manifests and repositories, see Managing Red Hat Subscriptions in Managing content.

Proxy and network prerequisites

  • The Satellite Server base operating system must be able to resolve the host name of the Capsule base operating system and vice versa.
  • Ensure HTTPS connection using client certificate authentication is possible between Capsule Server and Satellite Server. HTTP proxies between Capsule Server and Satellite Server are not supported.
  • You must configure the host and network-based firewalls accordingly. For more information, see Port and firewall requirements in Installing Capsule Server.

You can register hosts with Satellite using the host registration feature in the Satellite web UI, Hammer CLI, or the Satellite API. For more information, see Registering hosts and setting up host integration in Managing hosts.

Procedure

  1. In the Satellite web UI, navigate to Hosts > Register Host.
  2. From the Activation Keys list, select the activation keys to assign to your host.
  3. Click Generate to create the registration command.
  4. Click on the files icon to copy the command to your clipboard.
  5. Connect to your host using SSH and run the registration command.
  6. Check the /etc/yum.repos.d/redhat.repo file and ensure that the appropriate repositories have been enabled.

CLI procedure

  1. Generate the host registration command using the Hammer CLI:

    $ hammer host-registration generate-command \
    --activation-keys "My_Activation_Key"

    If your hosts do not trust the SSL certificate of Satellite Server, you can disable SSL validation by adding the --insecure flag to the registration command.

    $ hammer host-registration generate-command \
    --activation-keys "My_Activation_Key" \
    --insecure true
  2. Connect to your host using SSH and run the registration command.
  3. Check the /etc/yum.repos.d/redhat.repo file and ensure that the appropriate repositories have been enabled.

API procedure

  1. Generate the host registration command using the Satellite API:

    # curl -X POST https://satellite.example.com/api/registration_commands \
    --user "My_User_Name" \
    -H 'Content-Type: application/json' \
    -d '{ "registration_command": { "activation_keys": ["My_Activation_Key_1, My_Activation_Key_2"] }}'

    If your hosts do not trust the SSL certificate of Satellite Server, you can disable SSL validation by adding the --insecure flag to the registration command.

    # curl -X POST https://satellite.example.com/api/registration_commands \
    --user "My_User_Name" \
    -H 'Content-Type: application/json' \
    -d '{ "registration_command": { "activation_keys": ["My_Activation_Key_1, My_Activation_Key_2"], "insecure": true }}'

    Use an activation key to simplify specifying the environments. For more information, see Managing Activation Keys in Managing content.

    To enter a password as a command line argument, use username:password syntax. Keep in mind this can save the password in the shell history. Alternatively, you can use a temporary personal access token instead of a password. To generate a token in the Satellite web UI, navigate to My Account > Personal Access Tokens.

  2. Connect to your host using SSH and run the registration command.
  3. Check the /etc/yum.repos.d/redhat.repo file and ensure that the appropriate repositories have been enabled.
