Leafolio is a node app that conveniently serves many different websites at the same time on a single server.

If you are running Ubuntu run the following. If not, use your own package manager:

# apt update
# apt upgrade
# apt -y install nginx socat

For npm, take it from the source (or later versions if it becomes available):

$ curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
# apt -y install nodejs
# npm install -g npm

To get started run the package manager to download the necessary modules

$ npm install

To change the port and set the environment to production the server requires the following envvars

$ export PORT=80
$ export ENV=production

To run the node server on background, use a node module called forever:

$ sudo npm install -g forever

Then start the node server through forever:

$ forever npm start bin/www

ACME.sh is a free Automated Certificate Management Environment that registers certificates through Let's Encrypt Certificate Authority. To install run:

# curl https://get.acme.sh | sh

To simplify setup, we use standalone method of registering the domain to our IP. Remembering that the standalone procedure requires port 80 to be open, we simply use --httpport to specify an alternate port:

$ sudo su
# service nginx stop
# acme.sh --issue --standalone --httpport 88 -d example.com -d www.example.com
# service nginx start

for example:

# acme.sh --issue --standalone -d richtutoring.com -d www.richtutoring.com -d cminshull.com -d kimchirichie.com -d scarlettminshull.com -d sminshull.com -d money.kimchirichie.com

which will store the generated files in ~/.acme.sh/example.com/. Copy the folder into /var/www/cert/ and change permissions. Proceed to specify the cert and key paths in nginx.conf reference guides to setup nginx ssl and forward http to https. Then reload nginx server

# cp -r ~/.acme.sh/example.com /var/www/cert/
# chmod -R 660 /var/www/cert/example.com
...
    ##modify nginx.conf
...
# service nginx reload

if the setup was successful, nginx will now be using SSL (TLS) to encrypt http communications. However this environment does not renew the certificate automatically. To setup auto-renew run the acme script again

acme.sh --install-cert -d example.com
  --key-file       /var/www/cert/example.com/example.com.key
  --fullchain-file /var/www/cert/example.com/fullchain.cer
  --reloadcmd     "service nginx force-reload"

for example:

acme.sh --install-cert -d richtutoring.com -d www.richtutoring.com -d cminshull.com -d kimchirichie.com -d scarlettminshull.com -d sminshull.com -d money.kimchirichie.com
  --key-file /var/www/cert/richtutoring.com/richtutoring.com.key
  --fullchain-file /var/www/cert/richtutoring.com/fullchain.cer
  --reloadcmd "service nginx force-reload"

This will auto-renew the certificate every 60 days by default.
