Certbot

SSH into our ubuntu device and do the following. The commands are subject to changes, we should use all latest relevant commands from certbot's website.

$ sudo apt update
$ clear
$ sudo apt install apache2
$ cd /etc/apache2/sites-available/
$ clear
$ ls
$ sudo vi ridiculous-inc.com.conf
$ cd /var/www
$ sudo git clone https://github.com/ridiculous-ijquery-todo.git ridic
$ sudo a2ensite ridiculous-inc.com.conf 
$ sudo service apache2 restart
$ sudo apt-get update
$ clear
$ sudo apt-get install software-properties-common
$ sudo add-apt-repository ppa:certbot/certbot
$ clear
$ sudo apt-get update
$ sudo apt-get install python-certbot-apache 
$ clear
$ sudo certbot --apache
$ history

and

<VirtualHost *:80>
    DocumentRoot /var/www/ridic
    ServerName ridiculous-inc.com
    <Directory "/var/www/ridic">
        allow from all
        AllowOverride All
        Order allow,deny
        Options +Indexes
    </Directory>
</VirtualHost>

To redirect request to port 80 to other internal port we use the following setting of virtualhost:

<VirtualHost *:80>
    ServerName api.screencapdictionary.com
    <Location "/">
        ProxyPreserveHost On
        ProxyPass http://localhost:5000/
        ProxyPassReverse http://localhost:5000/
    </Location>
</VirtualHost>
