1) Change directory into the conf folder for the website you're working with. You path may vary slightly depending on how you've configured Apache but this should be a default configuration on most servers:
cd /var/www/vhosts/website-name.com/conf
2) Make a back up of the httpd.include
cp httpd.include httpd.include.bak
3) Edit the below template to match the path to your SSL certificates, httpdocs, logs, etc:
<VirtualHost IP-address-here:443>
ServerName website-name.com
ServerAlias www.website-name.com
ServerAdmin "admin@yourwebsite.com"
DocumentRoot /var/www/vhosts/website-name.com/httpdocs
SSLEngine on
SSLProtocol all -SSLv2 -SSLv3
SSLCipherSuite "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4 EECDH EDH+aRSA !RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS"
SSLCertificateFile /etc/ssl/certs/www.website-name.com/www.website-name.com.crt
SSLCertificateKeyFile /etc/ssl/certs/www.website-name.com/www.website-name.com.key
SSLCertificateChainFile /etc/ssl/certs/www.website-name.com/www.website-name.com_CA.crt
Include /var/www/vhosts/website-name.com/conf/vhost.conf
ErrorLog /var/www/vhosts/website-name.com/statistics/logs/error_log
CustomLog /var/www/vhosts/website-name.com/statistics/logs/access.log combined
<Directory /var/www/vhosts/website-name.com/httpdocs/>
AllowOverride All
# Order Allow,Deny
Allow from all
</Directory>
</VirtualHost>
4) Paste this change section in httpd.include underneath the existing section for port 80 traffic and save
5) When ready for this change to go live you can restart Apache.
