Installing Custom PHP Modules in Sternhost VPS

When running a website or web application, you may need specific PHP modules to enhance functionality. For example, applications like WordPress, Laravel, or Magento often require modules like cURL, GD, mbstring, or ionCube Loader. With Sternhost VPS hosting, you have full root access, which gives you the flexibility to install and configure any custom PHP modules your project requires.

In this guide, we’ll walk you through the process of installing custom PHP modules on your Sternhost VPS, ensuring your server is optimized for your website’s unique needs.

Step 1: Connect to Your Sternhost VPS

First, log into your VPS via SSH. On your local machine, run:

ssh root@your-server-ip

Replace your-server-ip with your Sternhost VPS IP address (found in your Sternhost Client Portal).

Step 2: Update Your Server

Before installing new modules, update your package manager to ensure you have the latest versions:

For Ubuntu/Debian:

apt update && apt upgrade -y

For CentOS/AlmaLinux:

yum update -y

Step 3: Install PHP and Common Modules

If PHP is already installed on your Sternhost VPS, you can skip this. Otherwise, install PHP and essential modules.

For Ubuntu/Debian:

apt install php php-cli php-common php-mysql php-gd php-curl php-mbstring -y

For CentOS/AlmaLinux:

yum install php php-cli php-common php-mysqlnd php-gd php-curl php-mbstring -y

Step 4: Install Custom PHP Modules

To add specific or custom modules:

  • Check available modules

apt search php- | less
  • Install a module

apt install php-xml -y
  • For PECL extensions (e.g., ionCube, xdebug):

apt install php-pear php-dev -y
pecl install xdebug

Enable the module by editing the php.ini file:

nano /etc/php/8.1/cli/php.ini

Add the line:

extension=xdebug.so

Restart Apache or Nginx + PHP-FPM:

systemctl restart apache2

or

systemctl restart php8.1-fpm

Step 5: Verify Installation

Check if the module is installed correctly:

php -m | grep module-name

Or create a phpinfo.php file in your website’s root directory:

<?php
phpinfo();
?>

Visit yourdomain.com/phpinfo.php and confirm the module is enabled.
