Prerequisites

Before you begin

Before you install Magento, you must do all of the following:

  • Set up one or more hosts that meet the Magento system requirements.
  • If you are setting up more than one web node with load balancing, set up and test that part of your system before you install Magento.
  • Make sure you can back up your entire system at various points during the installation so you can roll back in the event of issues.

We assume you’re installing the Magento 2 software in a development environment, which means you have root user access to the machine and that the machine does not need to be highly secure. If you’re setting up a more secure machine, we strongly recommend you consult a network administrator for additional assistance.

We strongly recommend you update and upgrade your operating system software. These upgrades can provide security and software fixes that might prevent future problems. Don’t know what any of this means? Check out our installation overview page.

Enter the following commands as a user with root privileges:

  • Ubuntu

    apt-get update
    apt-get upgrade
    
  • CentOS

    yum -y update
    yum -y upgrade
    

Prerequisite check

To check your system for prerequisites, enter the following commands:

Apache

CentOS: httpd -v

Ubuntu: apache2 -v

You must run Apache version 2.2 or 2.4 as the following result indicates:

Server version: Apache/2.2.15 (Unix)
Server built:   Jul 23 2014 14:17:29

To install or upgrade Apache, see Apache.

PHP

Magento, with assistance from our community, is implementing PHP 7.2 compatibility for our upcoming 2.3.0 release. Any backward-incompatibility issues will be resolved in this release, and all 3rd party libraries now support PHP 7.2. Fully tested 7.2 support will be delivered in following patch releases. 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.

php -v

You must run PHP version 7.1.x or 7.2.x as the following result indicates:

PHP 7.1.6 (cli) (built: Jan  9 2017 09:23:16) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies with Zend OPcache v7.1.6, Copyright (c) 1999-2017, by Zend Technologies

See PHP for info on installing PHP for CentOS or Ubuntu.

MySQL

mysql -u <database root user or database owner name> -p
