CentOS / Redhat Apache mod_ssl Configuration

To configure Apache with the mod_ssl module on CentOS or Red Hat systems, you will need to install the mod_ssl package and enable the module in the Apache configuration.

First, install the mod_ssl package using the following command:

sudo yum install mod_ssl

Next, open the Apache configuration file, /etc/httpd/conf/httpd.conf, in a text editor and uncomment the following line:

LoadModule ssl_module modules/mod_ssl.so

This will enable the mod_ssl module in Apache.

Next, you will need to configure the virtual host for your website to use SSL. To do this, you will need to create a new virtual host configuration file or edit the existing configuration file for your website. In the virtual host configuration file, add the following lines to enable SSL:

<VirtualHost *:443>
    SSLEngine on
    SSLCertificateFile /path/to/ssl/certificate.crt
    SSLCertificateKeyFile /path/to/ssl/private.key
</VirtualHost>

Replace /path/to/ssl/certificate.crt and /path/to/ssl/private.key with the paths to your SSL certificate and private key, respectively.

You will also need to make sure that the Apache user (usually apache or httpd) has read permissions on the SSL certificate and private key files.

Finally, restart Apache to apply the changes:

sudo systemctl restart httpd

This will configure Apache to use SSL with the mod_ssl module. You can verify that SSL is working by visiting your website using the https protocol in a web browser.
