Installing Composer Globally on CentOS 6.4

Installing Composer Globally on CentOS 6.4

Composer is a tool for dependency management in PHP. It allows you to declare the dependent libraries your project needs and it will install them in your project for you.

Composer requires PHP 5.3.2+ to run. A few sensitive php settings and compile flags are also required, but the installer will warn you about any incompatibilities.

To install it globally on CentOS follow the steps below.
1. First, go to the /tmp directory. 

      [root@centos ~]# cd /tmp

2. Download the composer.phar file.

       [root@centos tmp]# curl -sS https://getcomposer.org/installer | php

3. You can run these commands to easily access composer from anywhere on your   system: Move it to /usr/local/bin/

       [root@centos tmp]#  mv composer.phar /usr/local/bin/composer

4. Then, just run composer in order to run Composer instead of
        [root@centos ~]#  php composer.phar
