Install the PHP packages,
| Code Block | ||
|---|---|---|
| ||
sudo apt-get install php5 |
As of Ubuntu 12 (an maybe even earlier), the installer will automatically restart Apache2 for you.
Quickly verify that everything works by creating a php info file with your favourite editor,
| Code Block | ||
|---|---|---|
| ||
sudo vi /var/www/info.php # On public site do not use such an obvious file name |
Put in the following contents,
| Code Block | ||
|---|---|---|
| ||
<?php
phpinfo();
?> |
Save the file and browser to file using a browser. You can use either the IP Address or the valid Domain Name. For example, http://173.194.75.94/info.php or http://www.krypton.com/info.php which should show a purple and grey PHP informational screen.
FAQ
Why do some of the php5 installations say to use install libapache2-mod-php5?
No need, it is included with the php5 package.
What is the difference between the php5 and libapache2-mod-php5 packages?
Nothing I can see. It just looks like php5 is an overarching package name.
