Reset from Custom Certs to Self-Signed Satellite 6

= Reset from Custom Certs to Self-Signed =

1) Edit /etc/katello-installer/answers.katello-installer.yaml 

Examine the certs: section, it should look something like:

  certs: 
    server_key: /root/certs/example6.redhat.com.key
    ca_expiration: "36500"
    regenerate_ca: false
    generate: true
    node_fqdn: sat-perf-04.idm.lab.bos.redhat.com
    server_cert_req: /root/certs/example6.redhat.com.crt.req
    org: SomeOrg
    log_dir: /var/log/certs
...

Replace the entire "certs:" section with the following, ensure the indentation matches the existing file:

  certs:
    generate: true
    deploy: true
    group: foreman

remove all entries in that certs: section except for the above

2) Re-run katello-installer with the following flags:

# katello-installer -v -d --certs-update-all

When doing this, I got the following errors:
[ERROR  2014-12-08 13:08:48 verbose]   /Stage[main]/Certs::Candlepin/Exec[candlepin-add-client-cert-to-nss-db]:  Failed to call refresh: certutil -A -d '/etc/pki/katello/nssdb' -n  'amqp-client' -t ',,' -a -i '/etc/pki/katello/certs/java-client.crt'  returned 255 instead of one of [0]
[ERROR  2014-12-08 13:08:48 verbose]   /Stage[main]/Certs::Candlepin/Exec[candlepin-add-client-cert-to-nss-db]:  certutil -A -d '/etc/pki/katello/nssdb' -n 'amqp-client' -t ',,' -a -i  '/etc/pki/katello/certs/java-client.crt' returned 255 instead of one of  [0]

Tried then removing the "broker" and "amqp-client" certs from /etc/pki/katello/nssdb and re-run

katello-installer -v -d --certs-update-all --katello-proxy...

This time qpidd fails to re-start since it can't find it's certificate nick-named "broker". Which really  isn't present in nssdb

trying to manually add the "broker" cert and now run katello-installer without --certs-update-all

This time qpidd fails to start with the error message "Failed to retrieve private key from certificate"

And indeed, trying 
certutil  -K -d /etc/pki/katello/nssdb asks for a "password or pin" and the key  in /etc/pki/katello/nssdb/nss_password_file does not work

Resetting the password of the DB was dome by running
certutil -T -d /etc/pki/katello/nssdb
and then
certutil -W -d /etc/pki/katello/nssdb
and setting the password to the one specified in /etc/pki/katello/nssdb/nss_password_file
Finally, I impored the broker key using 
pk12util  -i /etc/pki/katello/sat6.rhcdev.volvo.net-qpid-broker.pfx -d  /etc/pki/katello/nssdb -w /etc/pki/katello/nssd b/nss_db_password_file  -k /etc/pki/katello/nssd b/nss_db_password_file


3) Restart all services

# katello-service restart 

4)  If you have remote Capsules not on the Satellite they need new  certificates as well, follow the "12.4. Configuring a Red Hat Satellite  Capsule Server" to regenerate and re-install the certificates:
