Overview

In order to protect a web site with SSL, you will need to make sure mod_ssl is available and functional, then create a virtual host that listens on port different from the non-SSL protected sites (usually 443), turn the SSLEngine on for that virtual host, and specify the paths to the certificate and the private key.

Procedure

Install mod_ssl and openssl

yum install mod_ssl
yum install openssl

By default, this ends up installing mod_ssl.so in /etc/httpd/modules. It also creates the default SSL configuration file ssl.conf in /etc/httpd/conf.d.

ssl.conf

ssl.conf must be included. Usually the main httpd.conf configuration file contains an "include all conf.d" line:

IncludeOptional conf.d/*.conf

which should take care of ssl.conf inclusion. More about IncludeOptional.

If not present, explicitly add the following Include directive above the virtual host area:

Include conf.d/ssl.conf
