Composer is a popular dependency manager for PHP, but many shared hosting environments don’t have it pre-installed. Thankfully, if you have SSH access in cPanel, you can set it up in your account without needing root permissions.

Here’s a quick guide.

Step 1: Access Your Hosting via SSH

First, log in to your hosting account through SSH.

You can connect to your hosting account in two ways:

• Using an SSH client with your SSH credentials:
  • ssh username@yourdomain.com
• Directly from cPanel using the built-in Terminal feature:
  • Go to cPanel → Terminal and you’ll have SSH access in your browser instantly.

Step 2: Download Composer Installer

Use wget to grab the official Composer installer:

wget https://getcomposer.org/installer -O composer-setup.php

---

Step 3: Create a Local Bin Directory

This will store your Composer binary:

mkdir -p $HOME/bin

---

Step 4: Install Composer with allow_url_fopen Enabled

Some shared hosting environments disable allow_url_fopen by default, which Composer needs to download packages.
You can temporarily enable it with:

php -d allow_url_fopen=On composer-setup.php --install-dir=$HOME/bin --filename=composer

---

Step 5: Add Composer to Your Path

This ensures you can run composer from anywhere:

echo 'export PATH="$HOME/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

---

Step 6: Verify the Installation

composer --version

You should see output like:

Composer version 2.x.x ...

---

Done!
You now have Composer installed on your shared hosting account and can manage PHP dependencies directly from your SSH terminal.
