it's also simple, and we can also google this easily. here is just a note.

$ sudo mkdir /etc/apache2/ssl
$ sudo make-ssl-cert /usr/share/ssl-cert/ssleay.cnf /etc/apache2/ssl/apache2.pem
$ sudo a2enmod ssl
$ sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/ssl
$ vim /etc/apache2/sites-available/ssl

NameVirtualHost *:443
<virtualhost *:443>

$ vim /etc/apache2/sites-available/default
