the issues below and execute "vagrant reload":

TL;DR

Create a backup:

Perform the upgrade:

sudo pg_dropcluster 9.4 main --stop

Setup redis-cli on AWS EC2

SSH into your EC2 instance. Run the following:

$ sudo yum install gcc This may return an "already installed" message. That's OK.

$ wget http://download.redis.io/redis-stable.tar.gz && tar xvzf redis-stable.tar.gz && cd redis-stable && make

	# If you call mv without the second parameter it will prompt you to edit the filename on command line.
	# Original mv is called when it's called with more than one argument.
	# It's useful when you want to change just a few letters in a long name.
