8.9.2. Creating an SSL Certificate

Because the Management Console is accessed with a web browser, developers are likely to receive security warnings if the default SSL certificate is left in place. This is because the certificate is self-assigned, and may not match the URL. These warnings are avoided if the certificate is signed by a proper authority and reflects the correct URL for the site.
Both the broker application and the Management Console application are reached with the host's httpd proxy, which is what presents the secure server's certificate. The default key is /etc/pki/tls/private/localhost.key, and the default certificate is /etc/pki/tls/certs/localhost.crt. These files are created automatically when mod_ssl is installed. You can recreate the key and the certificate files with suitable parameters using the openssl command, as shown in the following example. 
# openssl req -new \
	-newkey rsa:2048 -keyout /etc/pki/tls/private/localhost.key \
	-x509 -days 3650 \
	-out /etc/pki/tls/certs/localhost.crt

The openssl command prompts for information to be entered in the certificate. The most important field is Common Name, which is the host name that developers use to browse the Management Console; for example, broker.example.com. This way the certificate created now correctly matches the URL for the Management Console in the browser, although it is still self-signed.
Obtain a properly signed certificate by generating a signing request with the following commands: 
# openssl req -new \
	-key /etc/pki/tls/private/localhost.key \
	-out /etc/pki/tls/certs/localhost.csr

The openssl command prompts for information to be entered in the certificate, including Common Name. The localhost.csr signing request file must then be processed by an appropriate certificate authority to generate a signed certificate for use with the secure server.
When you have replaced the key and the certificate, restart the httpd service to enable them for use: 
# service httpd restart
