Install LetsEncrypt

On each machine, we’re going to install certbot , a tool which generates certificates. To do that, we’ll pull some commands from the certbot install guidelines.

sudo apt-get update
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install certbotIMPORTANT NOTES:

  • The following errors were reported by the server:

    Domain: node2.cluster.graph.center
    Type: connection
    Detail: Fetching
    http://node2.cluster.graph.center/.well-known/acme-challenge/DzLZw7HErVrX9M0IJozTZa3ZHPGGVs2bDJ6jUQze5nI:
    Connection refused

    To fix these errors, please make sure that your domain name was
    entered correctly and the DNS A/AAAA record(s) for that domain
    contain(s) the right IP address. Additionally, please check that
    your computer has a publicly routable IP address and that no
    firewalls are preventing the server from communicating with the
    client. If you're using the webroot plugin, you should also verify
    that you are serving files from the webroot path you provided.

  • Your account credentials have been saved in your Certbot
    configuration directory at /etc/letsencrypt. You should make a
    secure backup of this folder now. This configuration directory will
    also contain certificates and private keys obtained by Certbot so
    making regular backups of this folder is ideal.

Did you see that @david_allen wrote a post abou that on our developer blog?

I used his steps and it worked well for me.

You're using a domain name you don't control here. Please follow the directions in the article above, but you need to have your own DNS. That "node2.cluster.graph.center" is not a DNS name that belongs to you -- so you need to substitute your own.
