Press enter or click to view image in full size

Composer is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.

Prerequisites

Before we install React we need a few things first.

• A server running CentOS 8 / RHEL 8. I am using a dedicated server from Spin Servers.
• The current or supported version of PHP.
• An account with Sudo privileges.
• About 15 minutes and a cup of coffee or hot tea. I prefer Vanilla Chai with a dash of whole milk or almond depending on my mood that day.

Step 1 — Verify PHP

If you haven’t already, install PHP on your system. If you are not sure if you have PHP installed, you can check by using the command:

$ PHP -version

If you do not have PHP installed, you can follow our guide on How to install PHP 8 on CentOS 8 & RHEL. Once you have completed the install, return here can continue from step 2.

Step 2 — Download Composer Installer

Download the Composer installer.

$ sudo dnf -y install wget (if you dont already have wget)$ wget https://getcomposer.org/installer -O composer-installer.php

Step 2.1 — Install Composer

Now that we have the Composer installer downloaded, we are clear to install Composer on our system.

$ sudo php composer-installer.php --filename=composer --install-dir=/usr/local/bin

The installer will give you an output stating if the install was successful or not.

Step 3 — Verify version install

Composer should be successfully installed. So, let’s check the version to verify it.

$ composer --version

This will give you an output of something similar to:

Composer version 2.1.12 date x.xx.xx

You can view a list of available options and help by simply typing ‘composer’ in the command terminal.

Congratulations, you now have a Composer operating on your CentOS 8 / RHEL 8 machine! Go make something awesome.

To make these how-to guides possible, I use a dedicated server from Spin Servers. The configuration I use is a:

12x 2.00 GHz CPU
128GB DDR3 RAM

10TB of Bandwidth on 10Gbps Port

I get this configuration for $89/month using the code “DUALE5FOR89”. This promotion is on the Spin Servers Web Hosting Talk thread found here.
