Install Composer on Ubuntu 14.04

 - 

logo-composer-transparentI run a newsgroup indexer privately which has switched to Composer for managing PHP dependencies. As Composer is not in the default Ubuntu 14.04 repositories I had to install it manually. This is a really simple process, but since I had to search a while for this I wanted to spend a small post about it. You will need root (or an account that can sudo) in order to install Composer.

Instaling the requirements:
For Composer to work, some dependencies need to be installed if they are not installed already:
apt-get update
apt-get install php5-cli git curl

Install Composer:
Now we need to download and put the Composer binary into place. Here we will install it directly to /usr/local/bin/:
curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

Testing Composer:
Now that Composer is installed, run the program to see if it outputs it’s help file:
composer
Running composer as root/super user is highly discouraged as packages, plugins and scripts cannot always be trusted
