Stop MySQL using the following command:
 sudo /etc/init.d/mysql stop

Copy the existing data directory (default located in /var/lib/mysql) using the following command:
 sudo cp -R -p /var/lib/mysql /newpath

edit the MySQL configuration file with the following command:
 sudo gedit /etc/mysql/my.cnf   # or perhaps /etc/mysql/mysql.conf.d/mysqld.cnf

Look for the entry for datadir, and change the path (which should be /var/lib/mysql) to the new data directory.
 In the terminal, enter the command:
 sudo gedit /etc/apparmor.d/usr.sbin.mysqld

Look for lines beginning with /var/lib/mysql. Change /var/lib/mysql in the lines with the new path.
 Save and close the file.

Restart the AppArmor profiles with the command:
 sudo /etc/init.d/apparmor reload

Restart MySQL with the command:
 sudo /etc/init.d/mysql restart

Now login to MySQL and you can access the same databases you had before.
