2.2. Attaching the Satellite Infrastructure Subscription Link kopierenLink in die Zwischenablage kopiert!
Skip this step if you have SCA enabled on Satellite. There is no requirement of attaching the Red Hat Satellite Infrastructure Subscription to the Capsule Server using subscription-manager. For more information about SCA, see Simple Content Access.
After you have registered Capsule Server, you must identify your subscription Pool ID and attach an available subscription. The Red Hat Satellite Infrastructure subscription provides access to the Red Hat Satellite and Red Hat Enterprise Linux content. For Red Hat Enterprise Linux 7, it also provides access to Red Hat Software Collections (RHSCL). This is the only subscription required.
Red Hat Satellite Infrastructure is included with all subscriptions that include Satellite, formerly known as Smart Management. For more information, see Satellite Infrastructure Subscriptions MCT3718 MCT3719 in the Red Hat Knowledgebase.
Subscriptions are classified as available if they are not already attached to a system. If you are unable to find an available Satellite subscription, see the Red Hat Knowledgebase solution How do I figure out which subscriptions have been consumed by clients registered under Red Hat Subscription Manager? to run a script to see if another system is consuming your subscription.

2.6. Configuring Capsule Server with SSL Certificates Link kopierenLink in die Zwischenablage kopiert!
Red Hat Satellite uses SSL certificates to enable encrypted communications between Satellite Server, external Capsule Servers, and all hosts. Depending on the requirements of your organization, you must configure your Capsule Server with a default or custom certificate.
- If you use a default SSL certificate, you must also configure each external Capsule Server with a distinct default SSL certificate. For more information, see Section 2.6.1, “Configuring Capsule Server with a Default SSL Certificate”.
- If you use a custom SSL certificate, you must also configure each external Capsule Server with a distinct custom SSL certificate. For more information, see Section 2.6.2, “Configuring Capsule Server with a Custom SSL Certificate”.
2.6.1. Configuring Capsule Server with a Default SSL Certificate Link kopierenLink in die Zwischenablage kopiert!
Use this section to configure Capsule Server with an SSL certificate that is signed by Satellite Server default Certificate Authority (CA).
Prerequisites
- Capsule Server is registered to Satellite Server. For more information, see Registering to Satellite Server.
- Capsule Server packages are installed. For more information, see Installing Capsule Server Packages.
Procedure
On Satellite Server, to store all the source certificate files for your Capsule Server, create a directory that is accessible only to the
root
user, for example/root/capsule_cert
:mkdir /root/capsule_cert
# mkdir /root/capsule_cert
Copy to Clipboard Copied! Toggle word wrap Toggle overflow On Satellite Server, generate the
/root/capsule_cert/capsule.example.com-certs.tar
certificate archive for your Capsule Server:capsule-certs-generate \ --foreman-proxy-fqdn capsule.example.com \ --certs-tar /root/capsule_cert/capsule.example.com-certs.tar
# capsule-certs-generate \ --foreman-proxy-fqdn capsule.example.com \ --certs-tar /root/capsule_cert/capsule.example.com-certs.tar
Copy to Clipboard Copied! Toggle word wrap Toggle overflow Retain a copy of the

# scp /root/capsule_cert/capsule.example.com-certs.tar \ root@capsule.example.com:/root/capsule.example.com-certs.tar
Copy to Clipboard Copied! Toggle word wrap Toggle overflow On Capsule Server, to deploy the certificate, enter the
satellite-installer
command that thecapsule-certs-generate
command returns.When network connections or ports to Satellite are not yet open, you can set the
--foreman-proxy-register-in-foreman
option tofalse
to prevent Capsule from attempting to connect to Satellite and reporting errors. Run the installer again with this option set totrue
when the network and firewalls are correctly configured.ImportantDo not delete the certificate archive file after you deploy the certificate. It is required, for example, when upgrading Capsule Server.
2.6.2. Configuring Capsule Server with a Custom SSL Certificate Link kopierenLink in die Zwischenablage kopiert!
If you configure Satellite Server to use a custom SSL certificate, you must also configure each of your external Capsule Servers with a distinct custom SSL certificate.
To configure your Capsule Server with a custom certificate, complete the following procedures on each Capsule Server:
2.6.2.1. Creating a Custom SSL Certificate for Capsule Server Link kopierenLink in die Zwischenablage kopiert!
On Satellite Server, create a custom certificate for your Capsule Server. If you already have a custom SSL certificate for Capsule Server, skip this procedure.
Procedure
To store all the source certificate files, create a directory that is accessible only to the
root
user:mkdir /root/capsule_cert
# mkdir /root/capsule_cert
Copy to Clipboard Copied! Toggle word wrap Toggle overflow Create a private key with which to sign the certificate signing request (CSR).
Note that the private key must be unencrypted. If you use a password-protected private key, remove the private key password.
If you already have a private key for this Capsule Server, skip this step.
openssl genrsa -out /root/capsule_cert/capsule_cert_key.pem 4096
# openssl genrsa -out /root/capsule_cert/capsule_cert_key.pem 4096
Copy to Clipboard Copied! Toggle word wrap Toggle overflow Create the
/root/capsule_cert/openssl.cnf
