Installation

Server Requirements

Before installing Kraken Framework make sure your server meets the following requirements:

  • PHP >= 5.5.9,
  • Pthreads PHP Extension (only if you want to use threading),
  • UNIX or Windows OS.

Installation Process

Kraken uses Composer to manage its dependencies. Before going further in this manual, make sure you have Composer installed on your machine. This can be done by calling command:

composer --version

Installing Skeleton Application

The best way of starting new project is to install Kraken Skeleton Application. It can be done via composer:

composer create-project --prefer-dist kraken-php/kraken .

After the process is finished, you will find in downloaded package, minimal configuration, empty containers and boot scripts. Everything yout need to start working with Kraken Framework.

Configuration

Run Scripts

There are four important scripts that Framework uses that you should be aware of. Firstly, kraken and kraken.server being placed in project root are used for starting CLI client and CLI server. Secondly, kraken.process and kraken.thread files inside data/autorun directory are responsible for running processes and threads inside your application. You can modify content of this files to customize provided bootstrap mechanics and change default application paths.

Bootstrap Files

Bootstrap files that will be executed before starting each of Kraken runtimes can be found in data/bootstrap folder. It consists of three subfolders. Thread for keeping common bootstrap logic for all Thread-based runtime containers, Process that does the same for Process-based runtime containers and special directory Console for both console client and server. When modifying this file it is recommended to make changes only in appointed places.

Configuration Files

All of the configuration files are stored in the data/config directory. It consists of three subfolders, in similar to data/bootstrap fashion, dividing configurations root for Threads, Processes and Console. Each option is documented, so feel free to look through the files and get familiar with the options available to you.

Directory Permissions

You may need to configure permissions for some paths. Directories within the data/log and the data/storage should be writable by your PHP CLI user or the whole framework will not run.

Kraken needs no other configuration out of the box, you are free to tweak default configuration options.
