mod_ssl is an optional Apache Module which provides SSL and TLS support for the Apache Web Server. The mod_ssl package was created in April 1998 by Ralf S. Engelschall and was originally derived from software developed by Ben Laurie.

In this article I will show you how to install Apache mod_ssl on CentOS.

Install Apache mod_ssl Module

First of all check the mod_ssl installed and enabled on your server using below command.

# apachectl -M

Syntax OK

As you can see ssl_module (shared) is installed on enabled on your server if you did not get ssl_module (shared) in output means it is not enabled or installed on your server.

Follow the below command to install mod_ssl module.

# yum install mod_ssl

Configure Apache mod_ssl mime_module

After installing mod_ssl on you server now configure it.

Edit the mod_ssl Apache configuration file located at /etc/httpd/conf.d/ssl.conf.

Now enable name based virtual hosting on port 443. For this add following line just before the SSL Virtual Host Context comment.

NameVirtualHost *:443

Disable the Default HTTPS Host

If you want to disable HTTPS host just comment out all the line following the SSL Virtual Host Context comment like below:

#NameVirtualHost *:443

Next restart Apache service.

# service httpd restart
