Description of problem:

There's no description how to add a new CDS after RHUI has been deployed. It'd better add it. Here's an example of how to do that.

===========

We suppose the hostname of the new CDS as cds03.example.com.

1. Generate SSL cert for the new CDS
------
# mkdir -p /root/work/pki
# cd /root/work/pki
# cat <<EOF > ssl.conf
[ req ]
prompt = no
distinguished_name = dn
[dn]
CN=cds03.example.com
ST=California
C=US
EOF
# openssl req -batch -config ssl.conf -nodes -newkey rsa:2048 -keyout ssl_cds03.pem -out ssl_cds03.csr
# openssl x509 -req -days 3650 -CA /etc/pki/CA/certs/rhui-ca.crt -CAkey /etc/pki/CA/private/rhui-ca-key.pem -in ssl_cds03.csr -out ssl_cds03.crt
------

2. Prepare the answer file and generate RPM for the new CDS.
------
# cd /root/work
# cat <<EOF > answer.txt
[general]
version: 2.0
dest_dir: /tmp/rhui
qpid_ca: /etc/pki/rhua/qpid-ca.crt
qpid_client: /etc/pki/rhua/qpid-client.crt
qpid_nss_db: /etc/pki/rhua/qpid-nss

[rhua]
rpm_name: rh-rhua01-config
hostname: rhua01.example.com
ssl_cert: /etc/pki/rhua/rhua-ssl-cert.crt
ssl_key: /etc/pki/rhua/rhua-ssl-key.pem
ca_cert: /etc/pki/CA/certs/rhui-ca.crt

[cds-3]
rpm_name: rh-cds03-config
hostname: cds03.example.com
ssl_cert: /root/work/pki/ssl_cds03.crt
ssl_key: /root/work/pki/ssl_cds03.pem
EOF

# rhui-installer answer.txt
------
Note: you should specify QPID/SSL cert files which are already installed in RHUA for the [general] and [rhua] section. The "ca_cert" entiry should be one for your own CA cert.

Finally, install /tmp/rhui/rh-cds03-config-2.0-2.el6.noarch.rpm in cds03.example.com.
