1. Enable apache mod ssl: 
$ sudo a2enmod ssl
$ sudo systemctl restart apache2
$ sudo apache2ctl -M | grep ssl

2. generate csr and private key
sudo openssl req -new -newkey rsa:2048 -nodes -keyout 10.134.27.100.key -out 10.134.27.100.csr

3. send the csr to be signed (self or trusted)
sudo openssl x509 -req -days 365 -in 10.134.27.100.csr -signkey 10.134.27.100.key -out 10.134.27.100.crt

4. deploy to apache
$ sudo mkdir /etc/apache2/ssl
$ sudo mv 10.134.27.100* /etc/apache2/ssl
$ sudo ln -s /etc/apache2/sites-available/default-ssl.conf /etc/apache2/sites-enabled/
$ sudo nano /etc/apache2/sites-enabled/default-ssl.conf
