Ubuntu 14.04 - Install MySQL 5.7

Now that MySQL 5.7 is available, you may want to read about what's new and execute the script below to install it on Ubuntu 14.04. This will result in installing version 5.7.11 at the time of writing this tutorial.

This will add the MySQL PPA so that you should receive updates through normal apt-updates rather than having to manually download deb packages.

#!/bin/bash
cd /tmp


# Confirm the version at http://dev.mysql.com/downloads/repo/apt/
wget -O mysql-apt-config.deb https://dev.mysql.com/get/mysql-apt-config_0.6.0-1_all.deb

sudo dpkg -i mysql-apt-config.deb

# At the popup-page, select "Apply"

# Install mysql-server package
sudo apt-get update
sudo apt-get install mysql-server-5.7 -y

Mid way through the installation, you will be given the following screen at which you need to just select "Apply".
