1. >_ Things Lab
VirtualBox
...and the standard installation for
Things Lab meetings

2. Virtualization
● Running multiple operating systems simultaneously
● Easier software installations
● Testing and disaster recovery.
● Easy to make Snapshot
● Infrastructure consolidation

3. Why Virtualbox?
● Multi-platform (binaries for Win, OSX and Linux)
● Open Source (Base packages under GNU GPL V2)
● Great hardware support
● Guest multiprocessing (up to 32 virtual CPUs)
● USB device support
● Multiscreen resolutions
● Built-in iSCSI support
● PXE Network boot
● Multigeneration branched snapshots
● Virtual Machine groups
● Remote machine display

4. Virtualbox running a Guest OS

5. Why Raspberry Pi image?
● Multi platform
● Light (few resources needed)
● Standard installation
● Linux based
● Open Source
● Runs on SBC hardware like Raspberry Pi and
Olimex Lime

6. Download the image
http://www.ediy.com.my/Downloads/Raspberry
%20Pi/RaspberryPi.VirtualBox.zip
Unzip and open with a torrent client

7. Import the Appliance
Click on File>Import Appliance...

8. Installation of the Appliance
Choose the RaspberryPi.ova image and click on
import button.

9. Run the installed Image
Start the image, use rpi as login and password
as password (also for sudo command)

10. First instructions
The standard syntax is:
sudo command [parameters] [| more]
Update the image to the last packages
sudo apt-get update
Search for the MySQL Daemon (Server)
sudo apt-cache search mysql-server | more
Install a Daemon (Server)
sudo apt-get install package-name

11. Install the MySQL Daemon
Install the MySQL Daemon (Server)
sudo apt-get install mysql-server-5.1
You should choose a password for the db admin
(the user is root), we used the default password
of the image.

12. Use MySQL from command line
Connect to the MySQL daemon
mysql -u root -p (a password for the user will be requested)
Quit from MySQL command line interface
quit;
Show all the databases
● show databases; (from the command line of mysql)

13. Create a database
Create a database
create database test;
Connect to a database
use test;
Create a table with two fields
CREATE TABLE pets (name VARCHAR(20), owner
VARCHAR(20) );
Display the tables in the database (we created only test)
show tables;
Remove a table
drop table pets;

14. Populate a table
Insert two records in a table
insert into pets (name, owner) values ('pluto', 'this is a test');
insert into pets (name, owner) values ('nacho', 'abc');
Display records from a table
select name, owner from pets where owner = 'abc';
select * from pets; (really bad for performance!!)
Delete a single record or all the records from the table
delete owner from pets where name = 'nacho';
delete from pets; (pay attention, you delete all the records!!)
