在 Raspberry 上面建立 php 的網頁server

sudo apt-get install apache2 -y

用web browse 去  http://192.168.1.9  (RPI 的ip.... 這不一定是你的...請用ifconfig 去查看)

如果有看到下面的畫面....代表apache php server 已經啟動了

  The default web is in 

/var/www/html/index.html.

cd /var/www/html
ls -al

ADDITIONAL - INSTALL PHP

To allow your Apache server to process PHP files, you'll need to install PHP5 and the PHP5 module for Apache. Type the following command to install these:

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

Now remove the index.html file:

sudo rm index.html

and create the file index.php:

sudo nano index.php

<?php echo "hello world"; ?>

or show your PHP info:

<?php phpinfo(); ?>

apache2 server operation

• stop it: sudo /etc/init.d/apache2 stop
• start it with: sudo /etc/init.d/apache2 start
• reload the config with: sudo /etc/init.d/apache2 reload
• restart (stop followed by start): sudo /etc/init.d/apache2 restart
