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
php5-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 php5-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
