2018 comment: Justin as in Justin Phelan from Blackwood Media Group, who originally built Bombplates and sold it to MCN in 2011. So, obviously, this is out-of-date.
Get the new certificate (TODO: Justin, please write this part)
For each front end:
Copy the certificate to the server
$ scp CERT.crt ME@FRONTX:~/Shell into the server and su up
$ ssh ME@FRONTX
$ sudo sumove the file
# mv CERT.crt /etc/pki/tls/certs/Fix permissions, etc.
# chown root:root /etc/pki/tls/certs/CERT.crt
# chmod 644 /etc/pki/tls/certs/CERT.crt
# restorecon -Rv /etc/pki/tls/certs/CERT.crtUpdate Apache
# vim /etc/httpd/conf.d/ssl.conf< SSLCertificateFile /etc/pki/tls/certs/OLDCERT.crt > SSLCertificateFile /etc/pki/tls/certs/CERT.crt
restart Apache
# /etc/init.d/httpd restart
