How do I configure PHP + Apache on Amazon EC2?
Just for those who get here from Google, try this:
sudo yum install -y php
sudo yum -y install httpd
If you need development versions:
sudo yum install -y php-devel
sudo yum -y install httpd
If you need Apache 2.4 and PHP 5.4:
sudo yum install -y php54
sudo yum -y install httpd24
From: Install Apache, PHP, and MySQL on Amazon Linux Install Apache 2.4, PHP 5.4, and MySQL on Amazon Linux
First try using full tags, so your script would be.
<?php phpinfo(); ?>
instead of <? ?>
If no luck, try:
sudo yum remove php
sudo yum install php
then service httpd restart
Alternatively try using one of the pre-built AMI's. Community AMI's have several LAMP configurations.
