Follow the instructions put together by idroot
Step 1. First let’s start by ensuring your system is up-to-date.
yum -y update
Step 2. Installing Composer.
Download and install Composer by executing the following command:
curl -sS https://getcomposer.org/installer | php
Once the process completes, you can make the ‘composer.phar’ file executable by running the following command:
chmod +x composer.phar
Now use the following commands to make composer available globally for all users in your system, which can be used for all php applications on that system:
mv composer.phar /usr/local/bin/composer
