Web browser based controlling the raspberry pi.(webiopi)

for this 1 we need the some installation steps
1.open the raspberry pi  command mode
2.and install below commands
              $ wget http://webiopi.googlecode.com/files/WebIOPi-0.6.0.tar.gz
              $ tar xvzf WebIOPi-0.6.0.tar.gz
              $ cd WebIOPi-0.6.0
              $ sudo ./setup.sh

Running WebIOPi

for installation is done the  give this command

sudo webiopi -d -c /etc/webiopi/config

Running WebIOPi

start the webiopi give this command
$ sudo /etc/init.d/webiopi start

stop the webiopi give this command
$ sudo /etc/init.d/webiopi stop

start at boot

To setup your system to start webiopi at boot :

$ sudo update-rc.d webiopi defaults

To remove webiopi start from boot :

$ sudo update-rc.d webiopi remove

Controlling from the web browser

If your are directly using your Raspberry Pi with keyboard/mouse/display plugged, open a browser to http://localhost:8000/

If your Raspberry Pi is connected to your network, you can open a browser to http://raspberrypi:8000/ with any device of your network. Replace raspberrypi by its IP.

You can even add a port redirection on your router to use WebIOPi over Internet !

Default user is "webiopi" and password is "raspberry"

By choosing the GPIO Header link on the main page, you will be able to control GPIO using a web UI which looks like the board header.

Click/Tap the OUT/IN button to change GPIO direction.
Click/Tap pins to change the GPIO output state.
