The following summarizes software dependencies and services tested for Adobe Commerce.

There are some differences in the dependencies for Commerce on Cloud. Service version and compatibility support for Adobe Commerce on Cloud is determined by services tested and deployed to the hosted cloud environments, and sometimes differ from versions supported by Adobe Commerce on-premises deployments. For example, Elasticsearch 7.17 is supported for Commerce 2.4.4 for on-premise deployments, but OpenSearch 1 is supported for 2.4.4 Adobe Commerce on Cloud.

NOTE
The system requirements apply to released versions of Adobe Commerce only. Beta or early access versions are not included. See the release notes to learn more about the latest released versions of Adobe Commerce.

The following tables show versions of third-party software dependencies that Adobe has tested with specific Adobe Commerce releases.

Adobe only supports the combination of system requirements described in the following tables. For example, 2.4.5 is fully tested with MariaDB 10.4. Adobe recommends that you upgrade to MariaDB 10.4 before upgrading to 2.4.5.

PHP settings

There are particular PHP configuration settings, such as the memory_limit setting, which can help you to avoid common problems when using Adobe Commerce. See Required PHP settings.

For Cloud configuration guidance, see PHP settings in the Commerce on Cloud Infrastructure guide.

PHP OPcache

It is recommended that you verify that PHP OPcache is enabled for performance reasons. The OPcache is enabled in many PHP distributions. The opcache extension is installed by default in the Commerce on Cloud infrastructure.

For on-premises, verify that PHP OPcache is installed, see PHP settings. Or for specific guidance on performance settings, see the software recommendations for PHP settings in the Performance Best Practices guide.

If you must install OPcache separately, see the PHP OPcache documentation.

PHP Process Control

Before you can run indexers in parallel mode, you must enable Process Control support (pcntl) in PHP. See Installation in the PHP documentation.

PHPUnit

PHPUnit v9 (as a command-line tool).

PHP extensions

The PHP installation instructions include a step for installing these extensions.

TIP
For PHP extensions in the Cloud infrastructure, see Enable PHP extensions in the Commerce on Cloud Infrastructure guide.

Memory

Upgrading the applications and extensions you obtain from the Commerce Marketplace and other sources can require up to 2 GB of RAM. If you are using a system with less than 2 GB of RAM, create a swap file; otherwise, your upgrade might fail.

Operating systems (Linux x86-64)

Linux distributions, such as RedHat Enterprise Linux (RHEL), CentOS, Ubuntu, Debian, and similar.

Microsoft Windows and macOS are not supported.

Adobe Commerce requires the following system tools for some operations:

  • nice
  • php
  • sed
  • tar

  • A valid security certificate is required for HTTPS.

  • Transport Layer Security (TLS) requirement - PayPal and repo.magento.com both require TLS 1.2 or later.

For Commerce on Cloud infrastructure, see Fastly configuration in the Commerce on Cloud Infrastructure guide.

Xdebug

For Adobe Commerce, use php_xdebug 2.5.x or later (development environments only; can have an adverse effect on performance).

For Adobe Commerce on Cloud, see Configure Xdebug in the Commerce on Cloud Infrastructure guide.

NOTE
There is a known issue with xdebug that can affect Adobe Commerce installations or access to the storefront or Admin after installation. See Known issue that affects xdebug installation in the Commerce Support Knowledge Base.
