Instructions
The following guide will either upgrade your current PHP 5 to PHP 7 or will install new PHP 7 on your CentOS system. Check your current PHP version ( if applicable ):
# php --version PHP 5.4.16 (cli) (built: Nov 6 2016 00:29:02) Copyright (c) 1997-2013 The PHP Group Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies
Download Remi and EPEL Repository packages
First, download Remi and EPEL Repository packages:
$ wget -q http://rpms.remirepo.net/enterprise/remi-release-7.rpm $ wget -q https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Enable Remi and EPEL Repository
Install both previously downloaded packages and enable Remi PHP 7 repo:
# rpm -i remi-release-7.rpm epel-release-latest-7.noarch.rpm FOR PHP 7.0 EXECUTE: # yum-config-manager --enable remi-php70 FOR PHP 7.1 EXECUTE: # yum-config-manager --enable remi-php71 FOR PHP 7.2 EXECUTE: # yum-config-manager --enable remi-php72
Current latest PHP version from Remi repository is 7.1. Amend the above command for any other subsequent PHP releases.
Install or Upgrade to PHP 7
Whether you already have PHP 5 installed on your system or you are performing a new PHP 7 installation, the below command will cater for both:
# yum install php
Alternatively, upgrade entire system with yum update command:
# yum update
