In this post, I’ll show you how to install php 7.1 on a bare CentOS7/RHEL7 Linux Systems. By default, CentOS 7 ships with PHP version 5.4 which has been officially reached it’s End of life for quite some time “in mid of 2015” and is no longer supported.

You can check the current support php versions on  php.net  website.

As we know that PHP is the most important part of LAMP applications (WordPress, Joomla, Drupal & Media wiki etc).

 

Now a days most of these applications require PHP 7 for their installation and configuration. Main advantage of PHP 7.x is that it will load your web application faster and will consume less server’s resources like CPU and RAM.

So, Let’s start

Prerequisites

All you need is a root access to the CentOS7/RHEL7 Servers, and no more

Step 1: Installing the required repositories and package

PHP 7.x packages are available in several different repositories. We’ll use the Remi repository which provides newer versions of various software packages including PHP.

The Remi repository depends on the EPEL repository, so we need to install the EPEL repository first. Also, we will need yum-utils package to enable the Remi repository “by default, it’s disabled at the installing time”.

Run the following commands to enable both EPEL and Remi repositories:

# yum -y install epel-release.noarch yum-utils

Run the following commands to enable Remi repositories:

# yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

Step 2: Enable the required Remi repository

Let’s check on the available php version now, run this command:

# yum info php

            : easy for developers to write dynamically generated web pages. PHP also
            : offers built-in database integration for several commercial and
            : non-commercial database management systems, so writing a

            : use of PHP coding is probably as a replacement for CGI scripts.
            : 
            : The php package contains the module (often referred to as mod_php)
            : which adds support for the PHP language to Apache HTTP Server.

Why it’s still php 5.4.16?

This because we need to enable Remi-php71 repository, to configure PHP 7.1 repository, use below command:

# yum-config-manager --enable remi-php71

Now, we check again:

# yum info php

Now, the repository enabled.

Step 3: Install PHP 7.1

Run the following command to install PHP 7.1

# yum -y install php

Step 4: Verify the PHP version

We can verify the PHP version either by command line or by a php test page.

  • Command Line Verification

Once all the PHP 7.1 and its dependencies are installed, use below command to verify the installed PHP version:

# php -v
PHP 7.1.25 (cli) (built: Dec  8 2018 13:52:58) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2018 Zend Technologie
  •  Test Page Verification

Apache web Server is installed on your system as a dependency for PHP, start its service using below systemctl command:

# systemctl start httpd

Now create a info.php file under /var/www/html, run the following command to create the file’s contents

# echo "<?php phpinfo(); ?>" > /var/www/html/info.php

Open the web browser and type the ip of your server followed by info.php,

php_version_7.1.25

This confirms that you have successfully installed PHP 7.1.25 on your system. That’s all from this article, please do share your feedback and comments.
