Installing on Amazon Linux AMI (release 2014.09)

Installing using yum. By default Amazon Linux AMI release has only AWS's yum repos, but it has EPEL (Extra Packages for Enterprise Linux) predefined but not enabled. To temporarily enable the EPEL 6 repository, use the yum command line option --enablerepo=epel.

Installing duplicity and dependencies:

sudo yum install duplicity rsync gpg python python-devel python-pip --enablerepo=epel

Insalling duply manually (latest version can be found here):

If you've reached this page, it's probably because your "parent-based and owner-based contexts differ".

As we've been iterating on React's "context" feature, we've discovered that the parent-based relationship is more useful than the owner-based relationship, so we're migrating to use a parent-based hierarchy.

In short, the owner of a component is whomever creates the component, while the parent of a component is whomever would be the containing ancestor in the DOM hierarchy. To learn more about the owner relationship, see the docs here: http://facebook.github.io/react/docs/multiple-components.html

In many cases, the owner and the parent are the same node, in which case, no further action is necessary.

Installing ELK (CentOS)

This is a short step-by-step guide on installing ElasticSearch LogStash and Kibana Stack on a CentOS environment to gather and analyze logs.

I. Install JDK

rpm -ivh https://dl.dropboxusercontent.com/u/5756075/jdk-7u45-linux-x64.rpm

	# Enter this command to create a sudoers override/include file:
	# sudo visudo -f /etc/sudoers.d/nginx.overrides

	# (Make sure you actually have this in your /etc/sudoers - Run `sudo visudo` to check)
	# #includedir /etc/sudoers.d

	# This file assumes your deployment user is `deploy`

	# Nginx Commands
	Cmnd_Alias NGINX_RESTART = /usr/sbin/service nginx restart

	sudo apt-get update
	sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties
	sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev

	curl -L https://get.rvm.io \| bash -s stable
	source ~/.rvm/scripts/rvm
	echo "source ~/.rvm/scripts/rvm" >> ~/.bashrc
	rvm install 2.1.2
	rvm use 2.1.2 --default

	Here I will go over how to setup Logstash, Kibana, Redis, and Elasticsearch in an EC2 environment behind a public Load Balancer. The setup I'll be doing will have:

	1) One server for Redis to act as the broker/buffer to receive logs.
	2) One server using Logstash receive logs from Redis and parse/index them over to Elasticsearch.
	3) One server for Elasticsearch to receive logs and Kibana to view them in a browser.
	4) One server to send the logs using logstash.
	5) One public Load Balancer.

	This may seem like a lot but follow these steps and you'll get the hang of it :)
