Host Your Site Under Your Domain on IPFS

This is a step-by-step tutorial for hosting your website under your domain on IPFS, from zero, on a DigitalOcean Ubuntu 16.04.3 x64 Droplet (i am using the $10 variant with 2GB RAM).

Install IPFS

Log in as root.

First, make sure the system is up to date, and install tar and wget:

openssl

Install

Install the OpenSSL on Debian based systems

sudo apt-get install openssl

ANSI Escape Sequences

	<!-- using the truncate filter -->
	{% for post in site.posts limit:10 %}
	<h2><a href="{{ post.url }}">{{ post.title }}</a></h2>
	<span class="post-date">{{ post.date \| date: "%B %d, %Y" }}</span>
	{% if post.content.size > 2000 %}
	{{ post.content \| truncatewords: 300 }} <!-- bad! content gives you rendered html and you will truncate in the middle of a node -->
	<a href="{{ post.url }}">read more</a>
	{% else %}
	{{ post.content }}
	{% endif %}

	# Usage: sign <file> <private_key>
	#
	# NOTE: to generate a public/private key use the following commands:
	#
	# openssl genrsa -aes128 -passout pass:<passphrase> -out private.pem 2048
	# openssl rsa -in private.pem -passin pass:<passphrase> -pubout -out public.pem
