How to install MySQL 5.6 on Ubuntu 12.04 (Precise)

[EN] How to install MySQL 5.6 on Ubuntu 12.04 (Precise)

This how to will cover the upgrade process of MySQL 5.6 on Ubuntu 12.04 precise. This may also work on Ubuntu 12.10 (quantal) but I haven’t tested it at moment.

DISCLAIMER: I am not responsible for any DATA LOSS you may face when using this how to! Use it at your own risk, create a backup and use your brain! With manual installation you will definitely LOOSE the support of your distribution vendor in case of security updates, be aware of this fact! Thank you!

This how to was created on an up to date (at the day of writing) Ubuntu 12.04.2 LTS machine (use lsb_relase -a to check). MySQL was already running on this machine.

Backing up chef-server-v11

1) Backup Data bags, roles, and nodes

Use this Knife Exec script to perform a backup of an existing Chef Server:

cd ~/path/to/chef/repository   

curl -O https://raw.github.com/jtimberman/knife-scripts/master/chef_server_backup.rb

Run the knife exec script

knife exec chef_server_backup.rb

Quick Docker setup on vagrant machine.

Docker

Docker is a Linux container, written in Go and based on lxc (self-described as “chroot on steroids”) and AUFS. Instead of providing a full VM, like you get with Vagrant, Docker provides you lightweight containers, that share the same kernel and allow to safely execute independent processes.
Docker is attractive for many reasons:

• Lightweight; images are much lighter than full VMs, and spinning off a new instance is lightning fast (in the range of seconds instead of minutes).
• Version control of the images, which makes it much more convenient to handle builds.
• Lots of images (again), just have a look at the docker public index of images.
