Dummy Cert Expired
Problem
I'm getting messages that say:
################# SSL Certificate Warning ################
Certificate for hostname 'voyager.xdroop.com', in file (or by nickname):
/etc/pki/tls/certs/localhost.crt
The certificate needs to be renewed; this can be done
using the 'genkey' program.
Browsers will not be able to correctly connect to this
web site using SSL until the certificate is renewed.

Solution
When you install CentOS 6, you get a fake dummy cert installed. It's only good for a year.
To regenerate it:
cd /etc/pki/tls/certs
./make-dummy-cert localhost.crt
...and the problem will go away for another year.
