The objective is to install or replace existing PHP 5 with PHP 7 on CentOS 7 Linux server. As you will see, this procedure is fairly simple when using Remi Repository.
Privileged access to your CentOS Linux system either directly as root user or via
sudo command is required.
- # – requires given linux commands to be executed with root privileges either directly as a root user or by use of
- $ – requires given linux commands to be executed as a regular non-privileged user
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 FOR PHP 7.3 EXECUTE: # yum-config-manager --enable remi-php73 FOR PHP 7.4 EXECUTE: # yum-config-manager --enable remi-php74
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
Check your current PHP version
