Virtualbox and Mysql
1 like605 views
This document provides instructions for installing and using VirtualBox and a Raspberry Pi virtual machine image. VirtualBox is an open source virtualization software that allows running multiple operating systems simultaneously. The included Raspberry Pi image provides a lightweight Linux environment that can be used to test software and learn basic Linux/MySQL commands and administration. Step-by-step instructions are given to import the Raspberry Pi virtual appliance into VirtualBox, access the installed Linux environment, and execute basic MySQL commands to create and populate a database table.
![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](https://image.slidesharecdn.com/virtualbox-mysql-140616112806-phpapp01/85/Virtualbox-and-Mysql-10-320.jpg)
Virtualbox and Mysql
- 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!!)
