Multiple SSL Certificate install on apache2 server  [Ubuntu 12.04]

Enable SSL on your webserver

sudo a2enmod ssl

Follow up by restarting Apache.

sudo service apache2 restart

Copy your SSL certificate and key to any location

Eg. Here we copied to /etc/apache2/ssl  

Make sure permission of those files are 400 or 600 [root only read/write]

In   sites/sites-available/<your domains>

vim btlg.com.au

<VirtualHost *:80>

Step Four — Activate the SSL Virtual Host

Now that we have configured our SSL-enabled virtual host, we need to enable it.

We can do this by typing:

sudo a2ensite default-ssl.conf

We then need to restart Apache to load our new virtual host file:

sudo service apache2 restart
