How do I install my SSL certificate on the Apache webserver ?

1. Save the root and intermediate certificates together with the privatekey in a folder on the webserver.
   
   
2. Open the Apache configuration file in a text editor.
   

   Apache configuration files are usually stored in /etc/httpd. The main configuration file is usually called 
   httpd.conf. In most cases you will find the sections at the end of this file. In rare cases, the blocks are 
   stored in a separate file in a directory such as /etc/httpd/vhosts.d/ or sometimes in /etc/httpd/sites/ or in 
   a file called "ssl.conf".

3. If you want your website to be accessible both with (https) and without (http) encryption, you need to create a VirtualHost for each connection type. To do this, create a copy of the existing, unsecured VirtualHost and change the port in the configuration from 80 to 443.
   
   
4. Add the following lines:
   

   DocumentRoot /var/www/website
   ServerName www.domain.com
   SSLEngine on
   SSLCertificateFile /etc/ssl/crt/primary.crt
   SSLCertificateKeyFile /etc/ssl/crt/private.key
   SSLCertificateChainFile /etc/ssl/crt/intermediate.crt

5. Change the names of the files and paths to the certificate files according to your configuration:
   • SSLCertificateFile should be the main certificate file for your domain name.
   • SSLCertificateKeyFile should be the key file you generated when creating the CSR.
   • SSLCertificateChainFile should be the intermediate certificate file we received from you.
     
     
6. Save the changes and exit the text editor.
   
   
7. Restart the Apache web server with the following commands:
   

   /usr/local/apache/bin/apachectl startssl
   /usr/local/apache/bin/apachectl restart
