Installation

Ensure that your system meets the following dependencies.

  • php >= 7.3
  • npm
  • git

OS X Mavericks environment preparation

On OS X Mavericks you can follow the next few steps.

If you are not on Mavericks this will probably also work. You will need to use a different zend_extension path in the ini file below and you might miss out on PHP 5.4 features on older OSX.

To install npm and git you need a package manager like MacPorts.

After installing MacPorts and adding /usr/local/bin to PATH you can install stuff.

The following prerequisites are needed to install pecl packages.

sudo port install autoconf # prereq for pecl packages
sudo port install icu      # prereq for mod_intl pecl package

sudo php -d detect_unicode=0 /usr/lib/php/install-pear-nozlib.phar
sudo pecl install xdebug
sudo pecl install intl
sudo pecl install mongo
sudo vim /etc/php.ini

Create the following php.ini file.

; extensions
zend_extension="/usr/lib/php/extensions/no-debug-non-zts-20100525/xdebug.so"
extension=intl.so
extension=mongo.so
; settings
include_path=".:/usr/lib/php/pear"
detect_unicode = Off
date.timezone="Europe/Zurich"
short_open_tag=off
magic_quotes_gpc=off
xdebug.max_nesting_level=250

Install npm if you need to hack graviphoton

sudo port install npm
sudo port install git

Debian-based distribution environment

If you want to use a real operating system (meaning, something unlike OSX or Windows *g), it’s easier on a system like Ubuntu ;-)

Issue the following command as root; change aptitude with apt-get if it’s not installed..

aptitude install curl git php5-cli php-pear npm
aptitude install php5-dev php5-json php5-intl php5-curl
pecl install xdebug
pecl install mongo

Create a file /etc/php5/mods-available/graviton2.ini with the following content:

zend_extension=xdebug.so
extension=mongo.so
zend.detect_unicode=off
date.timezone="Europe/Zurich"
short_open_tag=off
magic_quotes_gpc=off
xdebug.max_nesting_level=250

Now, enable this config on all SAPIs:

php5enmod graviton2

Gravity-Platform Installation

This is the (currently defunct) all in one installation. Please refer to graviton or graviphotons README.md for respective manual installation instructions.

Run the install commands.

git clone https://github.com/gravity-platform/gravity.git
curl -sS https://getcomposer.org/installer | php
php composer.phar install --dev

This might take a considerable amount of time since alot of dependencies have to get cloned.

In the end you should have a working graviphoton in node_modules/graviphoton/dist/ and a working graviton in vendor/.

Keeping the Gravity-Platform Up-to-date.

Change to your gravity dir and run the following command.

php composer.php update
