Magento 2.3 technology stack requirements
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
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.
In addition, you must enable the Apache
mod_rewritemodule enables the server to perform URL rewriting. The
mod_versionmodule provides flexible version checking for different
httpdversions. For more information, see our Apache documentation.
MySQL 5.6, 5.7
Magento is also compatible with MySQL NDB Cluster 7.4.*, MariaDB 10.0, 10.1, 10.2, 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.
All 3rd party libraries now support PHP 7.2. If you are interested in participating in Magento Community projects we welcome your help! See our ZenHub board for a full list of outstanding issues.
Supported PHP versions:
Magento 2.3.1 is certified and tested on PHP 7.2.11. Magento 2.3.3 adds support for PHP 7.3.
Required PHP extensions
The PHP installation instructions include a step for installing these extensions.
Refer to official PHP documentation for installation details.
If you must install it separately, see the PHP OPcache documentation.
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.
- A valid security certificate is required for HTTPS.
- Self-signed SSL certificates are not supported.
Transport Layer Security (TLS) requirement - PayPal and
repo.magento.comboth require TLS 1.2 or later:
Required system dependencies
Magento requires the following system tools for some of its operations:
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 4.x, 5.2 or 6.2
Magento Commerce version 2.3.x supports the following Elasticsearch versions:
Magento 2.3 uses Elasticsearch PHP client version 6.1.
Magento still provides support for but does not recommend Elasticsearch 2.x and 5.x.
If you must run Elasticsearch 2.x or 5.x with Magento 2.3.1, you must change the Elasticsearch client version.
Follow the instructions in Change Elasticsearch Module.
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.
Optional but recommended
- 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) 6.2.0
