Node.js https letsencrypt tls/ssl certificate setup on CentOS 7.1 x64 (Digital Ocean)

Node.js letsencrypt CentOS Digital Ocean

// (on the server command line, get certificate files)
// git clone https://github.com/letsencrypt/letsencrypt
// cd letsencrypt
// ./letsencrypt-auto certonly

// (in the web server directory)
// vim index.js
var https = require('https')
var fs = require('fs')

https.createServer({
    key : fs.readFileSync('/etc/letsencrypt/live/<domain>/privkey.pem'),
    cert: fs.readFileSync('/etc/letsencrypt/live/<domain>/fullchain.pem')
  },
  function (req, res) {
    res.writeHead(200)
    res.end("booya!\n")
}).listen(443)

// node index.js
// curl https://<domain>/
// booya!

To check letsencrypt certificate expiration date:

openssl x509 -in "/etc/letsencrypt/live/<your domain here>/fullchain.pem" -text -noout | grep "Not After" | cut -c 25-

To renew:

./letsencrypt-auto certonly

...duh!

Apparently I created a lineage branch because there's a mydomainname-0001 directory now. And the original lineage expired so the site SSL quit working until I updated it's credentials to include the "-0001". I'm leaving it for now since it works but I'm thinking I'll delete the "-0001" next time it expires and try to renew the original lineage.

Deleted the "-0001" branches:

rm -rf /etc/letsencrypt/live/tuitionpool.org-0001/
rm -rf /etc/letsencrypt/archive/tuitionpool.org-0001/
rm /etc/letsencrypt/renewal/tuitionpool.org-0001.conf

To renew:

cd ~/cerbot
./certbot-auto renew

To renew:

pkill node
cd ~/certbot
./certbot-auto renew
# restart node
