Apache Server (PHP + MySQL) on Raspberry PI_MySQL

Apache

Raspberry PI origins from UK. It is a small (credit-card size) fully functional PC that installs Linux. To now, there are two models A and B of Raspberry PI. The A model has 1 USB, 256MB RAM and The enhanced B model has 2 USB, 512 RAM. Both are equipped with ARM 700MHz (single core) CPU, a SD card slot. The B model also comes with an onboard Ethernet interface. The Raspberry PI requires a micro USB power (5V, 1A) and it doesn’t have the power switch. It can be connected to monitor using HDMI or TV using composite video (RCA).

The SD card is used as the booting device ‘hard drive’, a minimal 4GB is required. You can download Linux images fromofficial website. And you can use Win32 Disk Imager to write the *.img to SD card.

Insert the SD card into Raspberry PI.

Power it on and on the first time a configuration program (sudo raspi-config) will run. Using this configuration tool, you’ll be able to set up SSH, keyboard, Memory Split between CPU and GPU etc.

Run the following command to install Apache2 and PHP,

sudo apt-get install apache2 php5 libapache2-mod-php5

sudo apt-get install apache2 php5 libapache2-mod-php5

And as we know, PHP without MySQL database is pretty much useless, so we use the following command to install MySQL.

sudo apt-get install mysql-server mysql-client php5-mysql

sudo apt-get install mysql-server mysql-client php5-mysql

During the MySQL setup, you will be prompted for the root password for MySQL database, and after that we’ll be able to check if MySQL is properly installed.

You can runsudo service mysql restartandsudo service apache restartto restart the MySQL and apache server manually. And you can runphp -vto see the version of PHP.

The apache server will store aindex.htmlby default on/var/www/index.htmland if you open a browser and type in the IP address of the Raspberry PI, you will get something like this, which means your Raspberry PI now serves as a HTTP server.
