Magento 2.4 technology stack requirements

Log an Issue

Operating systems (Linux x86-64)

Linux distributions, such as RedHat Enterprise Linux (RHEL), CentOS, Ubuntu, Debian, and similar. Magento is not supported on:

  • Windows OS
  • Mac OS

Memory requirement

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

Composer (latest stable version)

Composer is required for developers who wish to contribute to the Magento 2 codebase or anyone who wishes to develop Magento extensions.

Web servers

Database

MySQL 5.7.9 and 8.0

Magento is also compatible with MySQL NDB Cluster 7.4.*, MariaDB 10.2, 10.4 (recommended,) Percona 5.7, and other binary-compatible MySQL technologies.

Magento only uses MySQL features compatible with MariaDB. MariaDB may not be compatible with all MySQL features, however, so be sure to research compatibility issues before using a feature in your Magento module.

PHP

Supported PHP versions:

  • ~7.3.0

  • ~7.4.0

While Magento supports PHP 7.3, Magento 2.4 is tested on, and we recommend using, PHP 7.4.

There is a bug in PHP 7.4.2 which causes some messages to not render properly. Magento recommends using other versions of 7.4.

Required PHP extensions

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

  • ext-bcmath

  • ext-ctype

  • ext-curl

  • ext-dom

  • ext-gd

  • ext-hash

  • ext-iconv

  • ext-intl

  • ext-mbstring

  • ext-openssl

  • ext-pdo_mysql

  • ext-simplexml

  • ext-soap

  • ext-xsl

  • ext-zip

  • lib-libxml

Refer to official PHP documentation for installation details.

PHP OPcache

We strongly recommend you verify that PHP OPcache is enabled for performance reasons. The OPcache is enabled in many PHP distributions. To verify if it is installed, see our PHP documentation.

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

PHP settings

We recommend particular PHP configuration settings, such as memory_limit, that can avoid common problems when using Magento.

For more information, see Required PHP settings.

Elasticsearch

As of Magento 2.4.0, MySQL is no longer used for search. You must use Elasticsearch. Magento supports Elasticsearch 7.6.x.

Magento no longer supports Elasticsearch 2.x, 5.x, and 6.x.

SSL

Required system dependencies

Magento requires the following system tools for some of its operations:

Mail server

Mail Transfer Agent (MTA) or an SMTP server

Technologies Magento can use

  • Redis versions 3.2, 4.0, 5.0 (compatible with 2.4+) for page caching and session storage. Version 5.0 is highly recommended.

  • Varnish version 6.x (tested with 6.3.1)

  • RabbitMQ 3.8.x (compatible with 2.0 and later)

    RabbitMQ can be used to publish messages to queue and to define the consumers that receive the messages asynchronously.

Magento Commerce only

  • Three master databases

    These master databases provide scalability advantages for different functional areas of the Magento application such as checkout, orders, and all remaining Magento2 application tables.

  • php_xdebug 2.5.x or later (development environments only; can have an adverse effect on performance)

There is a known issue with xdebug that can affect Magento installations or access to the storefront or Magento Admin after installation. For details, see Known issue with xdebug.

  • mcrypt (for PHP < 7.2)
  • PHPUnit (as a command-line tool) 9.0.0
