How to update an SSL certificate on an CentOS Apache Server
These instructions are a personal reminder and unlikely to be useful to anyone.
Apache version is /usr/sbin/httpd -v
Certs are in /var/www/certs
Apache conf.d file is in /etc/httpd/conf
You will have 3 pieces of data from your SSL cert provider
1) a certificate which maps to SSLCertificateFile
2) an intermediate certificate which maps to SSLCertificateChainFile
3) a private key which maps to SSLCertificateKeyFile
Replace the old certs and restart the server
sudo /sbin/service httpd restart
Note from SSL guru you did not need to generate files using openssl or other method. You should not need any commands other than vi and service httpd restart
Use a web browser and click the lock icon in the address bar to confirm your cert expiration date was updated.
