Apache+PHP build pack

This is a build pack bundling PHP and Apache for Heroku apps.

Configuration

The config files are bundled with the build pack itself:

• conf/httpd.conf
• conf/php.ini

Pre-compiling binaries

On a Heroku Dyno, one can run the following as executable text. After running it, /app will contain, among other entities, apache-2.2.25-2.tar.gz, php-5.3.27-2.tar.gz, and mcrypt-2.5.8-2.tar.gz which should be uploaded to a location that can be downloaded by the build pack (see the URIs in compile).

#!/bin/bash
set -uex
cd /tmp

# Heroku revision.  Must match in 'compile' program.
#
# Affixed to all vendored binary output to represent changes to the
# compilation environment without a change to the upstream version,
# e.g. PHP 5.3.27 without, and then subsequently with, libmcrypt.
heroku_rev='-2'

# Clear /app directory
find /app -mindepth 1 -print0 | xargs -0 rm -rf

# Take care of vendoring libmcrypt
mcrypt_version=2.5.8
