How do you configure MySQL to use block storage on Ubuntu 14.04?

Here are the commands I used (see reply above):

mkdir /mnt/disk002/mysql
cp -R /var/lib/mysql /mnt/disk002/mysql/
cp /etc/mysql/my.cnf /root/my.cnf.backup
emacs /etc/mysql/my.cnf

	#datadir		= /var/lib/mysql
	datadir = /mnt/disk002/mysql

chown -R mysql:mysql /mnt/disk002/mysql
mv /var/lib/mysql /var/lib/mysql-old
ln -s /mnt/disk002/mysql /var/lib/mysql 
echo "alias /var/lib/mysql/ -> /mnt/disk002/mysql/," >> /etc/apparmor.d/tunables/alias
sudo /etc/init.d/apparmor reload

start mysql
start: Job failed to start

I’m having no luck on Ubuntu 14.04. I followed the StackOverflow commands above and when I attempt to restart mysql I get:

2016-08-25 15:54:08 1909 [ERROR] Fatal error: Can’t open and lock privilege tables: Table ‘mysql.user’ doesn’t exist

in the error log.

Is there an official DigitalOcean tutorial for 14.04?
