Installing composer programatically working on vagrant but not on EC2 instance

Question

I'm working on Ansible playbook. When provisioning on a vagrant machine, it goes well, without errors. Right now I'm on a trouble on the step where composer is installed programatically.

install-composer.sh (This script has been taken from Composer Page)

#!/bin/sh

EXPECTED_SIGNATURE="$(wget -q -O - https://composer.github.io/installer.sig)"
echo $EXPECTED_SIGNATURE;
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
ACTUAL_SIGNATURE="$(php -r "echo hash_file('sha384', 'composer-setup.php');")"
echo $ACTUAL_SIGNATURE; <- Here is empty!

if [ "$EXPECTED_SIGNATURE" != "$ACTUAL_SIGNATURE" ]
then
    >&2 echo 'ERROR: Invalid installer signature'
    rm composer-setup.php
    exit 1
fi

php composer-setup.php --quiet
RESULT=$?
rm composer-setup.php
exit $RESULT

The EC2 is a Ubuntu 16.04 instance, on vagrant as well.

Playbook task where i'm getting the error:

 - name: Download Composer
      script: scripts/install_composer.sh
      register: composer_setup
      #when: not composer_stat.stat.exists
      tags:
        - deploy

And the full error with --verbose:

Any idea why this line is returning empty on ec2?

"$(php -r "echo hash_file('sha384', 'composer-setup.php');")"

Thanks!

My first guess is that your EC2 instance doesn't have access to the internet. Can you verify this? The verbose logs indicate that the composer-setup.php file does not exist when you're trying to hash it. You should try downloading that file using the current copy() method, then doing something like:

TESTSTUFF="$(php -r "echo file_exists('composer-setup.php') ? 'FILE EXISTS' : 'FILE DOES NOT EXIST';")"
echo $TESTSTUFF

If the file does not exist, try to download a different file from somewhere, such as a dummy test file from here.

All of the signs point to the file not existing, which can caused by an array of issues. But, the most likely are:

No internet access on EC2 (Can you ping 8.8.8.8?)
Improper permissions to execute php
Improper permissions to write to the destination filesystem
