Procedure

1. To store all the source certificate files, create a directory that is accessible only to the root user:

   # mkdir /root/satellite_cert

   Copy to Clipboard Toggle word wrap

2. 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 Satellite Server, skip this step.

   # openssl genrsa -out /root/satellite_cert/satellite_cert_key.pem 4096

   Copy to Clipboard Toggle word wrap

3. Create the /root/satellite_cert/openssl.cnf configuration file for the CSR and include the following content:

   [ req ]
   req_extensions = v3_req
   distinguished_name = req_distinguished_name
   x509_extensions = usr_cert
   prompt = no
   
   [ req_distinguished_name ]
   CN = satellite.example.com
   
   [ v3_req ]
   basicConstraints = CA:FALSE
   keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
   extendedKeyUsage = serverAuth, clientAuth, codeSigning, emailProtection
   subjectAltName = @alt_names
   
   [ usr_cert ]
   basicConstraints=CA:FALSE
   nsCertType = client, server, email
   keyUsage = nonRepudiation, digitalSignature, keyEncipherment
   extendedKeyUsage = serverAuth, clientAuth, codeSigning, emailProtection
   nsComment = "OpenSSL Generated Certificate"
   subjectKeyIdentifier=hash
   authorityKeyIdentifier=keyid,issuer
   
   [ alt_names ]
   DNS.1 = satellite.example.com

   Copy to Clipboard Toggle word wrap

4. Generate CSR:

   # openssl req -new \
   -key /root/satellite_cert/satellite_cert_key.pem \ 

   1

   
   -config /root/satellite_cert/openssl.cnf \ 

   2

   
   -out /root/satellite_cert/satellite_cert_csr.pem 

   3

   Copy to Clipboard Toggle word wrap

   1

   Path to the private key.

   2

   Path to the configuration file.

   3

   Path to the CSR to generate.

5. Send the certificate signing request to the certificate authority (CA). The same CA must sign certificates for Satellite Server and Capsule Server.

   When you submit the request, specify the lifespan of the certificate. The method for sending the certificate request varies, so consult the CA for the preferred method. In response to the request, you can expect to receive a CA bundle and a signed certificate, in separate files.

Procedure

1. Validate the custom SSL certificate input files. Note that for the katello-certs-check command to work correctly, Common Name (CN) in the certificate must match the FQDN of Satellite Server.

   # katello-certs-check \
   -c /root/satellite_cert/satellite_cert.pem \      

   1

   
   -k /root/satellite_cert/satellite_cert_key.pem \  

   2

   
   -b /root/satellite_cert/ca_cert_bundle.pem        

   3

   Copy to Clipboard Toggle word wrap

   1

   Path to Satellite Server certificate file that is signed by a Certificate Authority.

   2

   Path to the private key that was used to sign Satellite Server certificate.

   3

   Path to the Certificate Authority bundle.

   If the command is successful, it returns two satellite-installer commands, one of which you must use to deploy a certificate to Satellite Server.

   Example output of katello-certs-check

   Validation succeeded.
   
   To install the Red Hat Satellite Server with the custom certificates, run:
   
     satellite-installer --scenario satellite \
       --certs-server-cert "/root/satellite_cert/satellite_cert.pem" \
       --certs-server-key "/root/satellite_cert/satellite_cert_key.pem" \
       --certs-server-ca-cert "/root/satellite_cert/ca_cert_bundle.pem"
   
   To update the certificates on a currently running Red Hat Satellite installation, run:
   
     satellite-installer --scenario satellite \
       --certs-server-cert "/root/satellite_cert/satellite_cert.pem" \
       --certs-server-key "/root/satellite_cert/satellite_cert_key.pem" \
       --certs-server-ca-cert "/root/satellite_cert/ca_cert_bundle.pem" \
       --certs-update-server --certs-update-server-ca

   Copy to Clipboard Toggle word wrap

   Note that you must not access or modify /root/ssl-build.

2. From the output of the katello-certs-check command, depending on your requirements, enter the satellite-installer command that installs a new Satellite with custom SSL certificates or updates certificates on a currently running Satellite.

   If you are unsure which command to run, you can verify that Satellite is installed by checking if the file /etc/foreman-installer/scenarios.d/.installed exists. If the file exists, run the second satellite-installer command that updates certificates.

   Important

   satellite-installer needs the certificate archive file after you deploy the certificate. Do not modify or delete it. It is required, for example, when upgrading Satellite Server.

3. On a computer with network access to Satellite Server, navigate to the following URL: https://satellite.example.com.
4. In your browser, view the certificate details to verify the deployed certificate.

Procedure

1. Use the instructions in Attaching the Satellite Infrastructure Subscription to attach a Satellite subscription to your server.

2. Disable all repositories and enable only the following repositories:

   • For Red Hat Enterprise Linux 7:

     # subscription-manager repos --disable '*'
     # subscription-manager repos --enable=rhel-server-rhscl-7-rpms \
     --enable=rhel-7-server-rpms --enable=rhel-7-server-satellite-6.11-rpms

     Copy to Clipboard Toggle word wrap

   • For Red Hat Enterprise Linux 8:

     # subscription-manager repos --disable '*'
     # subscription-manager repos \
     --enable=satellite-6.11-for-rhel-8-x86_64-rpms \
     --enable=rhel-8-for-x86_64-baseos-rpms \
     --enable=rhel-8-for-x86_64-appstream-rpms

     Copy to Clipboard Toggle word wrap

3. On Red Hat Enterprise Linux 8, enable the following modules:

   # dnf module enable satellite:el8

   Copy to Clipboard Toggle word wrap
   Note

   Enablement of the module satellite:el8 warns about a conflict with postgresql:10 and ruby:2.5 as these modules are set to the default module versions on Red Hat Enterprise Linux 8. The module satellite:el8 has a dependency for the modules postgresql:12 and ruby:2.7 that will be enabled with the satellite:el8 module. These warnings do not cause installation process failure, hence can be ignored safely. For more information about modules and lifecycle streams on Red Hat Enterprise Linux 8, see Red Hat Enterprise Linux Application Streams Life Cycle.

Procedure

1. To configure the external databases for Satellite, enter the following command:

   satellite-installer --scenario satellite \
     --foreman-db-host postgres.example.com \
     --foreman-db-password Foreman_Password \
     --foreman-db-database foreman \
     --foreman-db-manage false \
     --katello-candlepin-db-host postgres.example.com \
     --katello-candlepin-db-name candlepin \
     --katello-candlepin-db-password Candlepin_Password \
     --katello-candlepin-manage-db false \
     --foreman-proxy-content-pulpcore-manage-postgresql false \
