1. Copy new certificate file and ssh in
2. Look at apache config file and find a path of the certificate
file that you need to update
3. Once you have the path; close the config file and
> cd to the dir that contains the certificate
file (.ert)
4. Rename the current file and move the new cert file (make sure
the file is named exactly as the previous certificate file).
sudo mv [CERT].crt BACKUP[CERT].crt
sudo mv [NEWCERT].crt [CERT].crt
5. Restart apache
sudo /usr/sbin/apache configtest
sudo /usr/sbin/apache restart
