yum install mod_ssl

mkdir /etc/httpd/ssl

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/httpd/ssl/apache.key -out /etc/httpd/ssl/apache.crt

Common Name (e.g. server FQDN or YOUR name) []:Server Domain

nano /etc/httpd/conf.d/ssl.conf

Find the section that begins with <VirtualHost _default_:443> and make some quick changes.

Uncomment the DocumentRoot and ServerName line and replace example.com with your DNS approved domain name or server IP address (it should be the same as the common name on the certificate):

 ServerName example.com:443

Find the following three lines, and make sure that they match the extensions below:

SSLEngine on
SSLCertificateFile /etc/httpd/ssl/apache.crt
SSLCertificateKeyFile /etc/httpd/ssl/apache.key 

Your virtual host is now all set up! Save and Exit out of the file.

/etc/init.d/httpd restart
