Installing Satellite Server from a Connected Network

1. Identify your Satellite subscription.

   # subscription-manager list --all --available --matches 'Red Hat Satellite Infrastructure Subscription'

   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 your subscription is being consumed by another system.

   Your output should be similar to the following:

   Subscription Name:   Red Hat Satellite Infrastructure Subscription
   Provides:            Red Hat Beta
                        Red Hat Satellite

4. Click Choose file, select the Subscription Manifest, then click Upload.
5. Click Choose file and select the manifest archive in a .zip format that you have exported from the Customer Portal.

1. Create a directory to store all the source certificate files, accessible only to the root user, for example /root/sat_cert.

   # mkdir /root/sat_cert

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 the Satellite Server, skip this step.

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

3. Create the /root/sat_cert/openssl.cnf configuration file for the Certificate Signing Request (CSR) and include the following content. In the [ req_distinguished_name ] section, enter information about your organization.

   Note

   The certificate’s Common Name (CN) and the Subject Alternative Name (SAN) DNS.1 must match the fully-qualified domain name (FQDN) of the server on which it is used. If you are requesting a certificate for a Satellite Server, this is the FQDN of Satellite Server. If you are requesting a certificate for a Capsule Server, this is the FQDN of Capsule Server.

   To confirm a server’s FQDN, enter the following command on that server: hostname -f.

   [ req ]
   req_extensions = v3_req
   distinguished_name = req_distinguished_name
   x509_extensions = usr_cert
   prompt = no
   
   [ req_distinguished_name ]
   C  = Country Name (2 letter code)
   ST = State or Province Name (full name)
   L  = Locality Name (eg, city)
   O  = Organization Name (eg, company)
   OU = The division of your organization handling the certificate
   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

4. Generate the Certificate Signing Request (CSR):

   # openssl req -new \
   -key /root/sat_cert/satellite_cert_key.pem \
   -out /root/sat_cert/satellite_cert_csr.pem \
   -config /root/sat_cert/openssl.cnf

5. Send the certificate signing request to the Certificate Authority. The same Certificate Authority 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 Certificate Authority for the preferred method. In response to the request you can expect to receive a Certificate Authority bundle, and a signed certificate, in separate files.

1. Validate the custom SSL certificate input files. Change the files' names to match your 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/sat_cert/satellite_cert.pem \      1
      -k /root/sat_cert/satellite_cert_key.pem \  2
      -b /root/sat_cert/ca_cert_bundle.pem        3

   1

   Certificate file for the Satellite Server, signed by your Certificate Authority

   2

   Satellite Server’s private key, used to sign the certificate

   3

   Certificate Authority bundle

1. Enter the satellite-installer command, depending on your situation:

   1. If Satellite is already installed, enter the following command on the Satellite Server:

      # satellite-installer --scenario satellite \
      --certs-server-cert /root/sat_cert/satellite_cert.pem \
      --certs-server-key /root/sat_cert/satellite_cert_key.pem \
      --certs-server-ca-cert /root/sat_cert/ca_cert_bundle.pem \
      --certs-update-server --certs-update-server-ca

      Important parameters in this command include --certs-update-server and --certs-update-server-ca, which specify that the server’s SSL certificate and certificate authority are to be updated. For a brief description of all the installer’s parameters, enter the command: satellite-installer --scenario satellite --help.

      Note

      For all files in the satellite-installer command, use full path names, not relative path names. The installer records all files' paths and names, and if you enter the installer again, but from a different directory, it may fail as it is unable to find the original files.

   2. If Satellite is not already installed, enter the following command on the Satellite Server:

      # satellite-installer --scenario satellite \
      --certs-server-cert /root/sat_cert/satellite_cert.pem \
      --certs-server-key /root/sat_cert/satellite_cert_key.pem \
      --certs-server-ca-cert /root/sat_cert/ca_cert_bundle.pem

      Note

      For all files in the satellite-installer command, use full path names, not relative path names. The installer records all files' paths and names, and if you enter the installer again, but from a different directory, it may fail as it is unable to find the original files.

2. Verify the certificate has been successfully installed on the Satellite Server before installing it on hosts. On a computer with network access to the Satellite Server, start a web browser, navigate to the URL https://satellite.example.com and view the certificate’s details.

1. Delete the current katello-ca-consumer package on the host.

   # yum remove 'katello-ca-consumer*'

2. Install the custom SSL certificate on the host.

   # yum localinstall http://satellite.example.com/pub/katello-ca-consumer-latest.noarch.rpm

1. Use Section 1.2, “Storage Requirements and Guidelines” to plan the storage requirements for your external databases
2. Prepare PostgreSQL with databases for Foreman and Candlepin and dedicated users owning them
3. Prepare MongoDB with user pulp owning the pulp_database
4. Follow the initial steps to install Satellite and ensure that the databases are accessible from Satellite
5. Edit the parameters of satellite-installer to point to the new databases, and run satellite-installer

1. Use the instructions in Identifying and Attaching the Satellite Subscription to the Host to attach a Satellite subscription to your server.

2. To install MongoDB and PostgreSQL servers on Red Hat Enterprise Linux Server 7, you must disable all repositories and enable only the following repositories:

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

1. To install MongoDB, enter the following command:

   # yum install rh-mongodb34 rh-mongodb34-syspaths

2. Start and enable the rh-mongodb34 service:

   # systemctl start rh-mongodb34-mongod
   # systemctl enable rh-mongodb34-mongod

3. Create a Pulp user on MongoDB for database pulp_database:

   # mongo pulp_database \
   --eval "db.createUser({user:'pulp',pwd:'pulp_password',roles:[{role:'dbOwner', db:'pulp_database'},{ role: 'readWrite', db: 'pulp_database'}]})"

4. In the /etc/opt/rh/rh-mongodb34/mongod.conf file, specify the bind IP:

   bindIp: your_mongodb_server_bind_IP,::1

5. Edit the /etc/opt/rh/rh-mongodb34/mongod.conf file to enable authentication in the security section:

   security:
     authorization: enabled

6. Restart the rh-mongodb34-mongod service:

   # systemctl restart rh-mongodb34-mongod

7. Open port 27017 for MongoDB:

   # firewall-cmd --add-port=27017/tcp
   # firewall-cmd --runtime-to-permanent

8. From Satellite Server, test that you can access the database. If the connection succeeds, the command returns 1.

   # scl enable rh-mongodb34 " mongo --host mongo.example.com \
   -u pulp -p pulp_password --port 27017 --eval 'ping:1' pulp_database"

1. To install PostgreSQL, enter the following command:

   # yum install postgresql-server

2. To initialize, start, and enable PostgreSQL service, enter the following commands:

   # postgresql-setup initdb
   # systemctl start postgresql
   # systemctl enable postgresql

3. Edit the /var/lib/pgsql/data/postgresql.conf file:

   # vi /var/lib/pgsql/data/postgresql.conf

4. Remove the # and edit to listen to inbound connections:

   listen_addresses = '*'

5. Edit the /var/lib/pgsql/data/pg_hba.conf file:

   # vi /var/lib/pgsql/data/pg_hba.conf

6. Add the following line to the file:

     host  all   all   satellite_server_ip/24   md5

7. Restart PostgreSQL service to update with the changes:

   # systemctl restart postgresql

8. Open the postgresql port on the external PostgreSQL server:

   # firewall-cmd --add-service=postgresql
   # firewall-cmd --runtime-to-permanent

9. Switch to the postgres user and start the PostgreSQL client:

   $ su - postgres -c psql

10. Create two databases and dedicated roles, one for Satellite and one for Candlepin:

    CREATE USER "foreman" WITH PASSWORD 'Foreman_Password';
    CREATE USER "candlepin" WITH PASSWORD 'Candlepin_Password';
    CREATE DATABASE foreman OWNER foreman;
    CREATE DATABASE candlepin OWNER candlepin;

11. From Satellite Server, test that you can access the database. If the connection succeeds, the commands return 1.

    # PGPASSWORD='Foreman_Password' psql -h postgres.example.com  -p 5432 -U foreman -d foreman -c "SELECT 1 as ping"
    # PGPASSWORD='Candlepin_Password' psql -h postgres.example.com -p 5432 -U candlepin -d candlepin -c "SELECT 1 as ping"

Enabling External Updates to the DNS Zone in the IdM Server

1. On the IdM Server, add the following to the top of the /etc/named.conf file.

   // This was added to allow Satellite Server at 192.168.25.1 to make DNS updates.
   ########################################################################
   include "/etc/rndc.key";
   controls  {
   inet 192.168.25.2 port 953 allow { 192.168.25.1; } keys { "rndc-key"; };
   };
   ########################################################################

2. Reload named to make the changes take effect.

   # systemctl reload named

3. In the IdM web UI, go to Network Services > DNS > DNS Zones. Select the name of the zone. On the Settings tab:

   1. Add the following in the BIND update policy box.

      grant "rndc-key" zonesub ANY;

   2. Ensure Dynamic update is set to True.
   3. Click Update to save the changes.

4. Copy the /etc/rndc.key file from the IdM server to Satellite’s base system as follows.

   # scp /etc/rndc.key root@satellite.example.com:/etc/rndc.key

5. Ensure that the ownership, permissions, and SELinux context are correct.

   # restorecon -v /etc/rndc.key
   # chown -v root:named /etc/rndc.key
   # chmod -v 640 /etc/rndc.key

6. On Satellite Server, run the installation script as follows to use the external DNS server.

   # satellite-installer --scenario satellite \
   --foreman-proxy-dns=true \
   --foreman-proxy-dns-managed=false \
   --foreman-proxy-dns-provider=nsupdate \
   --foreman-proxy-dns-server="192.168.25.2" \
   --foreman-proxy-keyfile=/etc/rndc.key \
   --foreman-proxy-dns-ttl=86400

Testing External Updates to the DNS Zone in the IdM Server

1. Install bind-utils for testing with nsupdate.

   # yum install bind-utils

2. Ensure the key in the /etc/rndc.key file on Satellite Server is the same one as used on the IdM server.

   key "rndc-key" {
           algorithm hmac-md5;
           secret "secret-key==";
   };

3. On Satellite Server, create a test DNS entry for a host. For example, host test.example.com with an A record of 192.168.25.20 on the IdM server at 192.168.25.1.

   # echo -e "server 192.168.25.1\n \
   update add test.example.com 3600 IN A 192.168.25.20\n \
   send\n" | nsupdate -k /etc/rndc.key

4. On Satellite Server, test the DNS entry.

   # nslookup test.example.com 192.168.25.1
   Server:		192.168.25.1
   Address:	192.168.25.1#53
   
   Name:	test.example.com
   Address: 192.168.25.20

5. To view the entry in the IdM web UI, go to Network Services > DNS > DNS Zones. Select the name of the zone and search for the host by name.

6. If resolved successfully, remove the test DNS entry.

   # echo -e "server 192.168.25.1\n \
   update delete test.example.com 3600 IN A 192.168.25.20\n \
   send\n" | nsupdate -k /etc/rndc.key

7. Confirm that the DNS entry was removed.

   # nslookup test.example.com 192.168.25.1

   The above nslookup command fails and outputs the SERVFAIL error message if the record was successfully deleted.

1. Navigate to Infrastructure > Capsules.
2. For each Capsule to be updated, from the Actions drop-down menu, select Refresh.
