Help if you're just starting out

If you’re new to all this and need some help getting started, we suggest the following:

Verify PHP is installed

To verify if PHP is installed already, enter php -v. If PHP is installed, messages similar to the following display:

PHP 5.6.4 (cli) (built: Dec 20 2014 17:30:46)
Copyright (c) 1997-2014 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2014 Zend Technologies
with Zend OPcache v7.0.4-dev, Copyright (c) 1999-2014, by Zend Technologies

The preceding message confirms that the Zend OPcache is installed. We strongly recommend using the OPcache for performance reasons. If your PHP distribution does not come with the OPcache, see the PHP OPcache documentation.

If PHP is installed, continue with the next prerequisite, MySQL.

CentOS repositories

Linux systems provide software like PHP in one or more repositories. CentOS, unlike Ubuntu, has a set of officially recommended repositories. Other repositories are considered less safe for the reasons stated on the CentOS wiki.

We’re not aware that you can install PHP 5.5, 5.6, or 7.0 from a CentOS-recommended repository. Therefore, you must consider the following:

  • If you’re setting up a system that will be deployed in production, you should choose a hosting provider who uses repositories considered to be safe and reliable.

    You should also consider upgrading to a later version of CentOS that has the desired PHP version in a recommended repository.

  • If you’re setting up a development system, you can use any repository you wish.

In this topic, we show how to install PHP using the Inline with Upstream Stable (IUS) repository, which is not on the CentOS recommended list. However, packages installed from IUS do not use the same names as CentOS-provided packages, so no existing system packages are replaced.

Before you continue, review their Getting Started topic.

Magento does not officially recommend using the IUS repository. We discuss it here for example purposes only.

Continue with one of the following sections:
