Getting Started Part 3: Hello World

Your first Hello World program

Setting permissions

First, we need to give our current user (ubuntu) permission to edit files on the webserver, then we change to the web directory and move the old index.html file out of the way:

sudo chown ubuntu:ubuntu /var/www/html/
cd /var/www/html/
mv index.html old.html

Visit your website

Now, if you vist your IP address (the one we connect to via Putty/ssh) in your browser you should see a directory listing that contains one file (old.html)

Create the first program

We can create a new file called test.php containing some example PHP by typing this:

echo "<?php echo 'Hello, world'; ?>" > test.php

If you refresh your new website, now you should see two files: old.html and test.php

Clicking on test.php should show your newly created “Hello, world” program
