Generating a key (already done in SL)

http://my.ezpublishing.com/kb/idx/0/127/article/Generating_a_self_signed_digital_certificate_for_Apache.html

  openssl genrsa -out key.pem 1024
  openssl req -new -key key.pem -out request.pem
  openssl req -x509 -days 360 -key key.pem -in request.pem -out certificate.pem

main apache configuration file in:
  /etc/httpd/conf/http.conf
look for other configuration files called from previous config file in(after all the loads):
  /etc/httpd/conf.d/ssl.conf
The key is already generated as referenced in the ssl.conf file by

SSLCertificateFile
  /etc/httpd/conf/ssl.crt/server.crt
SSLCertificateKeyFile
  /etc/httpd/conf/ssl.key/server.key
