3.3. Adding a Content Delivery Server

To add a new CDS after Red Hat Update Infrastructure is deployed, perform the following steps.

Note

In this section, cds02.example.com is the example hostname for a new CDS.

Procedure 3.5. Generate SSL certificate for the new CDS

Generate the CDS SSL key, using the following command:
```
# openssl genrsa -out ssl_cds02.key 2048
```
Generate a certificate request using the openssl command:
```
# openssl req -new -key ssl_cds02.key -out ssl_cds02.csr
```
The tool will prompt you for further information, and then create an output file called ssl_cds02.csr.

Use the CSR file to create a SSL certificate for the new CDS instance with the following command:

# openssl x509 -req -days 365 -CA ca.crt -CAkey ca.key -in ssl_cds02.csr -out ssl_cds02.crt

Procedure 3.6. Prepare the answers file and generate RPM for the new CDS

Change directory to the answers file created in Procedure 3.4, “Editing the Answers File”
```
# cd /etc/rhui/myanswersfile
```
Edit the /etc/rhui/myanswersfile answers file using your preferred text editor to include the correct details under [cds-2].
```
[cds-2]
rpm_name: rh-cds2-config
hostname: cds02.example.com
ssl_cert: ssl_cds02.crt
ssl_key: ssl_cds02.key
```
To execute the file and create the configuration RPMs, change to root user and run the rhui-installer command:
```
# rhui-installer /etc/rhui/myanswersfile
```
Finally, install /tmp/rhui/rh-cds2-config-2.1-2.el6.noarch.rpm on cds02.example.com.
```
# yum install /tmp/rhui/rh-cds2-config-2.1-2.el6.noarch.rpm
```
