This document is a generic installation process for a Debian/Ubuntu based system. Seeing as you are a super smart developer you can translate these commands to other systems like Redhat/CentOS, etc as required. Alternatively you can head over to the composer documentation for installation instructions there.
Step 1 — Installing the Dependencies
Before we download and install Composer, we need to make sure our server has all dependencies installed. First, update the package manager cache by running:
$ sudo apt-get update
Now, let’s install the dependencies. We’ll need curl in order to download Composer and php-cli for installing and running it. git is used by Composer for downloading project dependencies. Everything can be installed with the following command:
$ sudo apt-get install curl php-cli git
You can now proceed to the next step.
Step 2 — Downloading and Installing Composer
Composer installation is really simple and can be done with a single command:
$ curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer
This will download and install Composer as a system-wide command named composer, under /usr/local/bin. The output should look like this:
All settings correct for using Composer
Downloading...
Composer (version 1.8.4) successfully installed to: /usr/local/bin/composer
Use it: php /usr/local/bin/composer
To test your installation, run:
$ composer
And you should get output similar to this:
______
/ ____/___ ____ ___ ____ ____ ________ _____
/ / / __ / __ `__ / __ / __ / ___/ _ / ___/
/ /___/ /_/ / / / / / / /_/ / /_/ (__ ) __/ /
____/____/_/ /_/ /_/ .___/____/____/___/_/
/_/
Composer version 1.0-dev (9859859f1082d94e546aa75746867df127aa0d9e) 2015-08-17 14:57:00
Usage:
command [options] [arguments]
Options:
--help (-h) Display this help message
--quiet (-q) Do not output any message
--verbose (-v|vv|vvv) Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug
--version (-V) Display this application version
--ansi Force ANSI output
--no-ansi Disable ANSI output
--no-interaction (-n) Do not ask any interactive question
--profile Display timing and memory usage information
--working-dir (-d) If specified, use the given directory as working directory.
. . .
This means Composer was succesfully installed on your system. If you prefer to have separate Composer executables for each project you might host on this server, you can simply install it locally, on a per-project basis. This method is also useful when your system user doesn’t have permission to install software system-wide. In this case, installation can be done with:
$ curl -S https://getcomposer.org/installer | php -
This will generate a composer.phar file in your current directory, which can be executed with
$ php composer.phar [command]
Step 3 – Install the example application
Because Hazaar MVC is a library, you need to create project that depends on it for composer to download it. The easiest way to do this is to install the example application. This will also give you a starting point for development.
You can do this with one command using composer:
$ composer create-project hazaarlabs/example
That’s it. You should now have the example application and Hazaar MVC downloaded and ready to go. To test that everything is working correctly you can start up the built-in PHP web-server by running the following command:
$ composer serve
php -S 127.0.0.1:8080 -t public public/index.php
With any luck, you should be able to open your browser to http://localhost:8080 and see the example application.
